UPDATE Saturday 26th April 2025: very light, fine snow started as low as Idyllwild at 1145 and continued on/off all afternoon as I ascended to San Jacinto Peak. Total accumulation in the high country was barely one inch, as I described in a short video report recorded at the Peak (linked here). As I descended this evening, snow depth at Saddle Junction (8100 ft) was 0.5 inch (photo below), with a patchy 0.25 inch at Humber Park (6500 ft). The very light snow has not significantly altered the trail conditions described below. Spikes remain useful to carry, but are certainly not generally required.

—————————————————

The passage of a storm system largely to our north this weekend will draw the marine layer high up onto the west slope of the San Jacinto mountains, in a similar manner to the event described below on 16th-18th. This will result in cloudy, cool, and damp conditions at mid elevations on 26th-27th, with a forecast for light precipitation on Saturday 26th, in the afternoon and again overnight. Initially forecast to be drizzle, temperatures may be cold enough for very light snow as low as 5000 ft (unlikely to accumulate more than one inch). Temperatures will certainly be below freezing in the high country on 25th-28th, and even below seasonal on 26th-27th. The highest peaks may remain above the cloud, but an inch of snow has been predicted in the most recent forecasts.

Trails below 9000 ft have now generally cleared of snow (except the most sheltered areas) and even the highest peaks are rapidly clearing on all but their most sheltered slopes (example photos below). The Pacific Crest Trail has heavily-traveled tracks in the very limited areas – described below – where snow remains on the trail in the San Jacinto mountains. Spikes provide ample traction, but are no longer needed on most of the PCT.

Below-seasonal temperatures on 16th-18th April were accompanied by an especially deep and dense marine cloud layer (photos below), at times bringing thick fog to Idyllwild. Over the three days, sadly drizzle in Idyllwild only added up to 0.06 inch, with zero precipitation in the high country which remained above the cloud.

Spikes remain a useful option above about 9000 ft (lower in a handful of places) although with reliable grippy footwear, hikers experienced on icy snow will find spikes are generally no longer required on established tracks. This even includes the north side of Tahquitz Peak, although spikes – at least – remain strongly recommended there (details below).

Snow depths are no longer detailed below. This does not imply that there is no snow in the high country, rather that snow cover is generally too patchy in most areas to provide meaningful measurements or change hiking conditions. Forecast warm and sunny weather will result in continuing steady snowmelt.

Black Mountain Road remains closed (to vehicle traffic only) at the gate 1.7 miles up from Highway 243. USFS expects to reopen the road before the end of April. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is expected to be closed for the year due to staffing/budget reasons (the trail and road remain open for hikers however). USFS gates at Humber Park and South Ridge Road both reopened in late March after brief closures.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures have been above seasonal averages for much of April, and that trend is forecast to broadly continue for the remainder of the month, with temperatures getting especially warm from Tuesday 29th into the first week of May.

Another high marine layer event on the western slope will result in cloudy, cool, and damp conditions at mid elevations on 26th-27th, with a forecast for light drizzle (<0.2 inch) in Idyllwild on Saturday 26th, possibly mixed with, or turning to, very light snow down to 5000 ft. Temperatures well below freezing on 25th-28th in the high country may result in very light snow (1-2 inches) on 26th, but it is also possible that the uppermost elevations remain above the cloud.

Below-seasonal temperatures on 16th-18th April were accompanied by an especially deep and dense marine cloud layer which brought periodic very light drizzle. In Idyllwild this only added up to 0.06 inch across the three days, with no precipitation above 9000 ft.

The latest video discussion from National Weather Service San Diego (linked here) includes data that confirm that this winter in Southern California has been one of the driest and warmest on record – with observations back to 1850 – especially for our area of montane central Riverside Country. Projections for the next few months suggest a hotter-than-average summer, with no clarity at this time on the likelihood of monsoonal moisture reaching us before late summer, if at all.

At San Jacinto Peak (10,810ft/3295m) on Sunday 20th April 2025 at 0800 the air temperature was 36.8°F (3°C), with a “windchill” temperature of 34.9°F (2°C), 25% relative humidity, and a barely discernable SW breeze sustained at 0 mph gusting to 2.6 mph.

At the Peak on Thursday 17th April 2025 at 0850 the air temperature was 31.1°F (-1°C), with a windchill temperature of 20.5°F (-6°C), 25% relative humidity, and a light WNW wind sustained at 4 mph gusting to 9.6 mph.

At the Peak on Wednesday 16th April 2025 at 0815 the air temperature was 36.9°F (3°C), with a windchill temperature of 25.0°F (-4°C), 17% relative humidity, and a fresh SSW wind sustained at 7 mph gusting to 12.0 mph.

TRAIL CONDITIONS

Snowmelt has been generally rapid since the last notable storm in mid March, and will continue throughout the remainder of April. Snow depths and trail conditions in the first half of April more closely resembled May (or even early June in a good snow year).

Everywhere above about 9000 ft carrying spikes is recommended as established trails have been consolidated by hiker traffic. As always, spikes tend to be most useful for descending, even when they are not necessarily required for ascending. Hikers with considerable experience on snow and ice will find that spikes are now generally not required on the tracks of the established trail system.

The Pacific Crest Trail through the San Jacinto mountains is largely clear of snow. Snow is gone from Miles 151 (Highway 74) to about Mile 175. Snow cover averages 60% from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat). Snow cover is very patchy between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is about 80%. Miles 181-184 are sun-exposed and clear. Snow cover increases after Mile 184. There is a well-traveled boot track through an average of 50% snow cover on the PCT along Fuller Ridge (Miles 185.5-191). This track does not accurately follow the trail in places. Miles 186-186.5 and 187.5-188.3 in particular are sun-exposed and now snow-free. Most hikers will find spikes are useful in places throughout this section, but they are not required as the track is well-defined with good steps. The trail is functionally clear of snow from Mile 190 northwards.

PCT hikers should not attempt to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak, even though this looks temptingly short and simple on apps and maps (photo above, further details below).

Although the situation improved somewhat in 2024, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. About 60 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work.

PCT hikers are asked to respect that overnight stays are not permitted at or near San Jacinto Peak, including in the historic shelter, to minimize impacts to a sensitive subalpine environment. Officially Mt. San Jacinto State Park permits overnight stays only in established campgrounds (Little Round Valley and Strawberry Junction are good options for thru-hikers).

Devil’s Slide Trail [surveyed 17th April] is clear of snow.

The Ernie Maxwell Trail is clear of snow. The one remaining minor downed tree on this trail has been reported to the Forest Service.

The PCT heading north from Saddle Junction is clear of snow to 9000 ft (approx. Miles 179-180, a.k.a. “Angel’s Glide”).

Snow cover on the Wellman Trail [surveyed 17th April] is only 20% and is almost entirely confined the forested 0.3 mile section immediately north of Annie’s Junction. Wellman’s Cienega is unfrozen and flowing well.

The Peak Trail [surveyed 17th April] now averages only 40% snow cover, almost all of which is above 10,000 ft elevation. Snow cover is continuous in the north-facing and sheltered section at 9900-10,100 ft that is always slow to clear in spring. There is a well-traveled compacted posthole track on the uppermost part of the Peak Trail.

The East Ridge Trail route [surveyed 17th April] to San Jacinto Peak starting at 10,400 ft near Miller Peak remains almost fully snow-covered. The route has been much less-traveled with the recent clearing of the upper Peak Trail, but a posthole track through shallow snow remains.

South Ridge Trail [surveyed 18th April] from the top of South Ridge Road is clear of snow to Tahquitz Peak. Spikes are not required. South Ridge Road is lumpy but readily passable in any moderate clearance vehicle.

The 0.4 mile section of South Ridge Trail between Chinquapin Flat/PCT Mile 177 and Tahquitz Peak [surveyed twice weekly, most recently 18th April] has a single postholing boot track to follow through the steeply angled snow (photo above), which in its steepest section does not accurately follow the trail route and has considerable underlying ice. These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is still not recommended for most hikers at this time. Although the track is passable without spikes for the most experienced hikers, spikes at a minimum are strongly recommended, should be accompanied by hiking poles or ideally an ice axe, and, critically, adequate experience and knowledge of how to use this equipment in such terrain.

Spitler Peak Trail is clear of snow [multiple surveys in March and April]. Storms in February-March brought down another 34 trees across this trail. All but one were removed in late March, bringing to 162 the total number of trees removed by the Trail Report from this route in the past six years. A very large burned cedar remains which can be a little tricky to pass, next to the first crossing of Spitler Creek (3.2 miles up from the trailhead, 1.6 miles down from the PCT).

Round Valley Trail is largely clear of snow from Long Valley to Round Valley. There is a well-traveled track through the remaining very thin and patchy snow from there to Wellman Divide.

Marion Mountain Trail [surveyed 20th April] is clear of snow, other than a limited patch right at the PCT junction.

Deer Springs Trail [surveyed 20th April] is clear of snow to just south of the junction with Marion Mountain Trail (about 1.5 miles north of Strawberry Junction). Thereafter thin snow cover averages 70% to San Jacinto Peak although many patches of trail, lengthy in places, are now clear in the most sun-exposed sections. The well-traveled track is generally easy to follow to Little Round Valley. Above Little Round Valley the trail is roughly 60% clear of snow but both the trail and the remaining posthole tracks are tricky to follow, with the latter frequently running into patches of cleared bushes and rocks. Spikes remain somewhat useful at least for descending upper Deer Springs Trail, but especially on mornings when the icy snow is crisp and dry, they are no longer required.

Seven Pines Trail [surveyed 24th April] is functionally clear of snow to 8200 ft, with about 40% cover of soft snow drifts from there to the PCT/Deer Springs Trail. Seventeen downed trees have been removed so far this month, and significant progress made on removal of accumulated winter debris in the trail up to about 8000 ft (photos below). The Trail Report “adopted” Seven Pines as a priority for maintenance work years ago due to a disproportionate number of lost hiker rescues in the previous decade, with neither State Park nor Forest Service having shown significant interest in maintaining the route for many years. Since 2019 we have removed 92 downed trees and the trail is generally trimmed and cleared at least annually. About six trees remain to be cut above the current snow line to restore the original trail route, plus one very large recently downed tree lower down. Although our work has largely restored this trail, note that Seven Pines remains a genuine wilderness trail unlike the wider, bare, obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains invaluable for those without considerable experience of hiking this trail. Also note the trail becomes most obscure in its uppermost mile – especially at present due to snow drifts – i.e. closest to the Deer Springs Trail/PCT junction.

The Caramba Trail from near Reeds Meadow through Laws Camp and on to Caramba, and the Cedar Trail from Willow Creek Trail to Laws, are euphemistically (and potentially dangerously) described by the Forest Service as “not maintained”. In reality both trails have been abandoned and no longer exist. They are so heavily overgrown, largely with dense whitethorn which obscures dozens of downed trees, that hikers should not attempt to follow them (regardless of how much you may trust an app). An informal use trail to Laws is much more direct, generally well maintained, and avoids the bushwhacking of the unmaintained trails (some local Idyllwild hikers dubbed it the “King Trail” when I established the route in 2019). It leaves Willow Creek Trail exactly 1.0 mile from Saddle Junction, 0.46 mile from the Skunk Cabbage turning (trailhead at N 33.7796, W 116.6590). The route descends largely following established deer trails for 1.2 miles, meeting Willow Creek about 0.2 mile upstream from the site of the historic Laws Camp (the remains of which were destroyed by the 2013 Mountain Fire and subsequent flood and treefall damage). One huge tree fell in late 2024 across the King Trail about midway down and requires a minor scramble underneath (that tree will not be cut soon), while another fell in January 2025 close to the bottom of the trail that is relatively easy to cross over. Another five recently downed trees were either removed or worked around in January 2025, when the trail was thoroughly trimmed and cleared. From Laws east to Caramba the original Caramba Trail has been cairned by myself and others and can largely be followed with careful route-finding. My February 2025 survey counted about 120 trees down on this 2.1 miles of trail. It is extremely obscure for the first 0.5 mile east of the Willow Creek crossing, becoming more obvious (but still subtle) as it descends towards Caramba. Very cautious navigation is advised throughout the area.

In late 2024 Willow Creek Trail was nearing its 2020 condition, the last time the original trail route was fully cleared and passable. Four new trees came down on the Forest Service section in January, two of which are large and tricky for hikers to pass. In addition to trees being cut in 2024, whitethorn trimming was largely completed, mainly by volunteers, on the Forest Service side in late summer. On the State Park side localized trimming of the worst patches was undertaken in 2024, and the minor treefall hazards new in 2023/24 were removed, leaving just two major long term downed trees (both easy to pass for hikers).

The Zen Center Trail continues its serious deterioration that started following the 2013 Mountain Fire, with a combination of vigorous regrowth and treefall hazards further obscuring the route with each passing season. The lower and upper thirds of this trail are partially cairned and not too bad for those who are very familiar with the former route, but even the experienced find navigating the central section tricky. Long trousers, scrambling gloves, and a genuine enjoyment of bush-whacking are all strongly recommended.

With temperatures well above seasonal on 6th-15th April at all elevations, melting of snow has been predictably rapid and widespread. Trails below 9000 ft have generally cleared (except the most sheltered areas) and even the highest peaks are largely clear on sun-exposed slopes. The air temperature of 50.3°F (10°C) recorded at San Jacinto Peak on Friday 11th was the highest ever reported for the Peak in April, and was more typical of midsummer months.

The PCT-specific section has now been incorporated into Trail Conditions and abbreviated due to the speed of melting and the relative ease of conditions at this time. The Pacific Crest Trail has very well-traveled tracks in the limited areas (described below) where snow remains on the trail in the San Jacinto mountains. Spikes provide ample traction, but are no longer needed on most of the PCT.

Below-seasonal temperatures on 17th-18th April may be accompanied by light rain (<0.3 inch) at mid elevations, and a decreasing possibility of a dusting of snow (<0.5 inch) in the high country. Temperatures will briefly be well below freezing at the highest elevations on 17th-19th. Trail conditions are not expected to be significantly altered by this brief change in weather.

Spikes remain useful above about 9000 ft (lower in places) although with reliable grippy footwear, hikers very experienced on icy snow will find spikes are generally no longer required on established tracks. Crampons remain an option on the north side of Tahquitz Peak for another week or so, although spikes are now sufficient (details below). Crampons are otherwise of very limited use elsewhere on the trail system. Snow depths and conditions are unsuitable for snowshoes.

Snow depths are no longer detailed below. This does not imply that there is no snow in the high country, simply that snow cover is generally too thin and so patchy in most areas to provide meaningful measurements or change hiking conditions. Forecast mild and sunny weather (with the exception noted above) will lead to further steady snowmelt.

Black Mountain Road remains closed (to vehicle traffic only) at the gate 1.7 miles up from Highway 243. USFS expects to reopen the road by the end of April. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is expected to be closed for the year due to staffing/budget reasons (the trail and road remain open for hikers however). USFS gates at Humber Park and South Ridge Road both reopened in late March after brief closures due to winter conditions.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

WEATHER

Unseasonably warm weather arrived on 5th April, and temperatures rose far above seasonal on 9th-11th, more typical of June, or even a mild midsummer day. The air temperature of 50.3°F (10°C) that I recorded at San Jacinto Peak on Friday 11th was the highest ever observed at the Peak in April.

Temperatures briefly drop closer to seasonal starting Wednesday 16th. A rising marine layer penetrating well inland will bring below-seasonal temperatures on 17th-18th April accompanied by light rain (<0.3 inch) at mid elevations, and the possibility of a dusting of snow (<1.0 inch) in the high country. Temperatures will briefly be well below freezing at the highest elevations on 17th-19th.

Temperatures quickly rise again above seasonal for the remainder of April from 19th onward, with no significant further precipitation in the forecasts.

At San Jacinto Peak (10,810ft/3295m) on Thursday 17th April 2025 at 0850 the air temperature was 31.1°F (-1°C), with a windchill temperature of 20.5°F (-6°C), 25% relative humidity, and a light WNW wind sustained at 4 mph gusting to 9.6 mph.

At the Peak on Wednesday 16th April 2025 at 0815 the air temperature was 36.9°F (3°C), with a windchill temperature of 25.0°F (-4°C), 17% relative humidity, and a fresh SSW wind sustained at 7 mph gusting to 12.0 mph.

At the Peak on Friday 11th April 2025 at 0835 the air temperature was 50.3°F (10°C), with a “windchill” temperature of 44.8°F (7°C), 10% relative humidity, and a light SW breeze sustained at 2 mph gusting to 6.6 mph.

TRAIL CONDITIONS

Snowmelt has been rapid since the last significant storm in mid March, and is expected to continue to be steady throughout the remainder of April. Snow depths and trail conditions in the first half of April more closely resemble May (or even early June in a good snow year).

Everywhere above about 9000 ft carrying spikes is recommended as established trails have been consolidated by hiker traffic. As always, spikes tend to be most useful for descending, even when they are not necessarily required for ascending. Hikers with considerable experience on snow and ice will find that spikes are now generally not required on the tracks of the established trail system.

The entire Pacific Crest Trail through the San Jacinto mountains is readily passable. The trail is clear of snow from Miles 151 (Highway 74) to about Mile 175. Snow cover averages 70% from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat). Snow cover is very patchy between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is about 90%. Miles 181-184 are sun-exposed and clear. There is a well-traveled boot track through variable snow cover on the PCT along Fuller Ridge (Miles 185.5-191). This track does not accurately follow the trail in places. Miles 186-186.5 and 187.5-188.3 are now snow-free. Most hikers will find spikes are useful in places throughout this section, but they are not required. The trail is functionally clear of snow from Mile 190 northwards.

PCT hikers should not attempt to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak, even though this looks temptingly short and simple on apps and maps (photo above, further details below).

Although the situation improved somewhat in 2024, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. About 60 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak).

Devil’s Slide Trail [surveyed 17th April] is clear of snow.

The Ernie Maxwell Trail is clear of snow. The couple of minor downed trees on this trail have been reported to the Forest Service.

The PCT heading north from Saddle Junction (a.k.a. “Angel’s Glide”) is functionally clear of snow to 9000 ft.

Snow cover on the Wellman Trail [surveyed 17th April] is only 20% and is almost entirely confined the forested 0.3 mile section immediately north of Annie’s Junction. Wellman’s Cienega is unfrozen and flowing well.

Thirteen downed trees have been removed so far this month, and significant progress made on removal of accumulated winter debris in the trail up to about 8000 ft. The Trail Report “adopted” Seven Pines as a priority for maintenance work due to a disproportionate number of lost hiker rescues in the past decade, with neither State Park nor Forest Service having shown significant interest in maintaining the route for many years. Since 2019 we have removed 88 downed trees and the trail is trimmed and raked regularly. About ten trees remain to be cut above the current snow line, with one large one lower down. Although our work has hugely improved the condition of the trail, Seven Pines remains a genuine wilderness trail unlike the wider, bare, and much more obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains invaluable for those without considerable experience of hiking this trail. Note the trail becomes most obscure in its uppermost mile, closest to the Deer Springs Trail/PCT junction.

UPDATE Friday 11th April 2025: Melting has been very rapid as expected, and hikers this weekend will find conditions are generally more benign than described below. Most snow has now gone from areas below 9000 ft, especially on sun-exposed slopes. Snow above that elevation is generally so thin and compacted that postholing in established tracks is actually minimal. Carrying spikes remains wise for most hikers everywhere above about 9000 ft.

———————————-

In a year already full of major swings in weather, the most dramatic is underway. After a lovely cool first few cloudy days of April, with a light dusting of snow on Wednesday 2nd, and firm, reliable snow tracks, temperatures rise dramatically this week. The impacts of this change will be especially noticeable as snow is relatively shallow everywhere, and with such unseasonably hot weather, rapid melting will bring back the sloppy postholing of late March, with quickly clearing trails especially below 9000 ft and, in the most sun-exposed areas, even up to the highest peaks.

This update includes a detailed PCT-specific section (between Weather and Trail Conditions), although much of the remainder of the Report includes material relevant to thru hikers also. The Pacific Crest Trail has well-traveled tracks where snow remains along its entire length in the San Jacinto mountains. Spikes are sufficient traction everywhere on the PCT, but are no longer required in many areas.

Carrying spikes remains recommended everywhere above about 7500 ft, although with reliably grippy footwear, hikers with significant experience on icy snow will find they are not required for travel on or adjacent to established tracks. To give a sense of conditions, although I have carried spikes as a precaution, I have not used them for my last five ascents (via various routes) of San Jacinto Peak in the past ten days.

Crampons are preferable on the north side of Tahquitz Peak (details below). Crampons can be used elsewhere on the high country trails, generally above 9000 ft, but they are certainly not required, and will become far less suitable as snow-free patches rapidly appear throughout the high country in the next few days.

Snowshoes may again briefly become an option above about 9000 ft after about Monday 7th April on warm days from late morning onwards as snow softens dramatically (but consistent snow depths may well be too shallow in all but very sheltered areas).

Details of snow depths measured at a few sample locations on the trail system are given below (for what may be the final time this season, given the imminent dramatic melting expected). Note that snow depth itself is very rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example, a firm, well-compacted track across deep snow – e.g., see photo below – is often much easier hiking than a less well-traveled track across just a few inches depth of angled icy snow.

Black Mountain Road remains closed (to vehicle traffic only) at the gate 1.7 miles up from Highway 243 due to winter conditions. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is expected to be closed for the year due to staffing/funding reasons. USFS gates at Humber Park and South Ridge Road both reopened in late March after brief closures due to winter conditions.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 1-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

WEATHER

A minor storm on 2nd April produced only very light snow, with 0.5 inch in Idyllwild and locations up to 7000 ft, 0.75 inch at Saddle Junction (PCT Mile 179), and just two inches everywhere from 9000 ft up to San Jacinto Peak. Fresh snow was so shallow that most had melted in sun-exposed areas within a day or two, despite cold temperatures.

Sadly, summer temperatures arrive 2-3 months ahead of schedule this week, albeit only briefly. Temperatures started to rise steadily on Saturday 5th, and will be more typical of June, or even a mild midsummer day, on 9th-11th. Temperatures may drop closer to seasonal the following week (by about 15th). Remaining snow will melt rapidly, and softer snow conditions will mean a return to the postholing of late March.

Temperatures are forecast to remain largely above seasonal for the remainder of April, and the prospects for significant further precipitation are also poor, as described in detail in the latest video report from National Weather Service San Diego (linked here).

Idyllwild is currently at about 85% of seasonal snowfall for the water year, but only 45% of average rainfall. We will once again be dependent on an increasingly unreliable monsoon season to approach an average water year.

At San Jacinto Peak (10,810ft/3295m) on Sunday 6th April 2025 at 0800 the air temperature was 27.8°F (-2°C), with a windchill temperature of 8.8°F (-13°C), 39% relative humidity, and a steady NE wind sustained at 20 mph gusting to 25.3 mph.

At the Peak on Friday 4th April 2025 at 0845 the air temperature was 15.1°F (-9°C), with a windchill temperature of -4.5°F (-20°C), 90% relative humidity, and a sharp NNE wind sustained at 11 mph gusting to 16.8 mph.

At the Peak on Thursday 3rd April 2025 at 0910 the air temperature was 12.8°F (-11°C), with a windchill temperature of -9.0°F (-23°C), 100% relative humidity, and a frigid NNE wind sustained at 15 mph gusting to 19.8 mph.

PACIFIC CREST TRAIL

All of the PCT in the San Jacinto mountains is readily passable with, crucially, suitable skills and equipment, patience, and a thorough knowledge of all possible alternates if needed. Snowmelt has been rapid since the last significant storm in mid March, and is expected to continue to be fast throughout the remainder of April.

There is a continuous boot track on the PCT through the entire San Jacinto mountains. However, that does not mean the hike is easy, as laborious postholing will be required in many areas this month as temperatures rise markedly.

The trail is largely clear of snow from Miles 151 (Highway 74) to about Mile 174. Limited patchy snow remains on north-facing and sheltered slopes, such as the descent to Fobes Saddle, and on the east side of Spitler Peak. Apache Peak is now largely clear of icy snow, and those wishing to avoid now there altogether can pass over the top of the Apache Peak saddle (leave the trail due north at about Mile 169.2).

Snow cover is largely continuous from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat), although the terrain is generally benign. Many hikers will find spikes useful on this section.

PCT hikers should not attempt to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak, even though this looks temptingly short and simple on apps and maps. This section of steeply angled (and notoriously treacherous) ice slopes remains challenging weeks after surrounding trails have melted, and currently requires crampons, ice axe, and the expertise to use that equipment.

Snow cover is becoming patchy between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is largely clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is almost continuous (phot above). Miles 181-183 are sun-exposed and are largely clear. Snow cover is largely continuous from Mile 184 through to about Mile 192. Most hikers will find spikes are very useful throughout this section.

There is a moderately traveled postholing boot track through variable snow cover on the PCT along Fuller Ridge (Miles 185.5-191). This track does not accurately follow the trail in places. Extensive snow-free sections are now developing on Miles 186-186.5 and 187.5-188.3. At this time continuing north on Fuller Ridge requires the skills and comfort level to hike on angled terrain with some moderate exposure, and spikes are recommended (although not essential for the experienced). Taking the Black Mountain Road alternate remains an excellent option for hikers less comfortable with the Fuller Ridge section for the next week or so.

A well established alternate from Idyllwild – avoiding Fuller Ridge – is to connect back to the PCT at about Mile 191 using Black Mountain Road. Black Mountain Road is clear of snow for the lower five miles, and then has only patchy snow cover for the upper three miles to the PCT but with an obvious track following the road through the snow patches. Mile 192 northward to Interstate 10 is clear of snow.

Although the situation improved somewhat in 2024, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed February 2025).

PCT hikers are asked to respect that overnight stays are not permitted at or near San Jacinto Peak, including in the historic shelter, to minimize impacts to a sensitive subalpine environment. Officially Mt. San Jacinto State Park permits overnight stays only in established campgrounds (Little Round Valley and Strawberry Junction are good options for thru-hikers).

TRAIL CONDITIONS

Where snow remains, tracks are in place for almost all trails. Melting has been fast since the very minor storm on 2nd April, and will accelerate dramatically this week with the first major heatwave of the year. Conditions this week will deteriorate for snow hiking, with the softening snow lending itself to significant sloppy postholing.

Everywhere above about 7500 ft carrying spikes is recommended as established trails have been consolidated by hiker traffic. As always, spikes tend to be most useful for descending, even when they are not necessarily required for ascending. Hikers with considerable experience on snow and ice will find that spikes are now generally not required on the tracks of the established trail system.

For details of specifics of downed trees, prior to the March snow storms, see an earlier Report (linked here).

Devil’s Slide Trail [surveyed 4th April] is rapidly clearing of snow, with just a few limited, dirty patches remaining, largely concentrated close to Saddle Junction. Most hikers will find spikes are no longer required.

The Ernie Maxwell Trail is clear of snow. The couple of minor downed trees on this trail were recently reported to the Forest Service.

From Saddle Junction northbound a well-defined posthole track – in areas that still have snow -continues to San Jacinto Peak through Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails [all surveyed 30th March].

The PCT heading north from Saddle Junction (a.k.a. “Angel’s Glide”) is largely clear of snow to 9000 ft. Snow cover remains about 90% from 9000 ft through Annie’s Junction and onward to near Wellman’s Cienega. Snow cover on the Wellman Trail averages only 50% [all surveyed 4th April].

The Peak Trail route [surveyed 4th April] is very well-defined, and a few small snow-free patches are starting to appear. There is now a well-traveled posthole track on the uppermost part of the Peak Trail, but at 10,400 ft near Miller Peak, the alternate direct track climbs up the East Ridge Trail route, as is traditional in winter.

The 0.4 mile section of South Ridge Trail between Chinquapin Flat/PCT Mile 177 and Tahquitz Peak [surveyed 7th April] has an indistinct single boot track to follow through the steeply angled snow, which in its steepest section does not accurately follow the trail route and has considerable underlying ice (photo below). These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for almost all hikers at this time. Spikes at a minimum are strongly recommended (crampons preferable), should be accompanied by an ice axe, and, critically, adequate experience and knowledge of how to use this equipment in such terrain.

South Ridge Trail [surveyed 7th April] from the top of South Ridge Road is functionally clear of snow to Tahquitz Peak, with just a handful of tiny patches close to the peak. Spikes are not required. South Ridge Road is lumpy but passable in any moderate clearance vehicle.

Spitler Peak Trail [surveyed 27th March] is clear of snow. Storms in February-March brought down another 34 trees across this trail, but all of the small-to-medium-sized hazards were removed on 21st and 23rd March (bringing to 162 the total number of trees removed by the Trail Report from this route in the past six years). Just one very large burned cedar remains which can be a little tricky to pass, next to the first crossing of Spitler Creek (3.2 miles up from the trailhead, 1.6 miles down from the PCT).

Round Valley Trail is rapidly clearing of snow from Long Valley to Round Valley. There is a well-traveled track on increasingly patchy icy snow from there to Wellman Divide.

Marion Mountain Trail [surveyed 6th April] is largely clear of snow below 7500 ft, averaging about 10% snow cover. From that elevation to the junction with Deer Springs Trail/PCT, snow cover averages 40%. There is a well-worn track throughout all snow patches. Some hikers will find spikes are useful, at least for descending, but steps are so well-defined through the snow that spikes are certainly no longer required.

Deer Springs Trail [surveyed 6th April] is clear of snow from the Highway 243 trailhead to the Suicide Rock trail junction at 7000 ft. From there to Strawberry Junction (8100 ft) snow cover averages just 10% with snow patches increasing in length and frequency as you ascend. Spikes are not required as far as Strawberry Junction, even for descending. Snow cover is largely continuous from Strawberry Junction to San Jacinto Peak, although extensive clear sections are starting to appear below 8500 ft (south of the top of the Marion Mountain Trail). A well-traveled track is then generally easy to follow to Little Round Valley, although there are two tracks in places and even the more traveled option does not accurately follow the trail route in places. Above Little Round Valley there are multiple posthole tracks, all generally much more direct than the actual trail and none remotely following the established trail route (as is traditional in adequate snow conditions). There is one well-traveled track well north of the trail, and another well to the south, plus my very direct single posthole track straight to the Peak. Despite their challenges, all these routes do ultimately end up at San Jacinto Peak. Spikes are generally useful at least for descending upper Deer Springs Trail, but on mornings when the icy snow is crisp and dry, they are not required.

Seven Pines Trail [surveyed 9th and 12th April] is functionally clear of snow to 8200 ft, with about 50% cover of soft snow drifts from there to the PCT/Deer Springs Trail. Thirteen downed trees have been removed so far this month, and significant progress made on removal of accumulated winter debris in the trail up to about 8000 ft. The Trail Report “adopted” Seven Pines as a priority for maintenance work due to a disproportionate number of lost hiker rescues in the past decade, with neither State Park nor Forest Service having shown significant interest in maintaining the route for many years. Since 2019 we have removed 88 downed trees and the trail is trimmed and raked regularly. Currently about ten trees remain to be cut above the snow line, and one large one lower down. Although our work has hugely improved the condition of the trail, Seven Pines remains a genuine wilderness trail unlike the wider, bare, and much more obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains invaluable for those without considerable experience of hiking this trail. Note the trail becomes most obscure in its uppermost mile, closest to the Deer Springs Trail/PCT junction.

SNOW DEPTHS

Measured on 6th April (west slope locations) and 4th April 2025 (east side). The first number gives current average depth. Strong winds accompanying storms led to extensive drifting, and there has been highly variable melting in the past week or so. The number in parentheses indicates the greatest depth for that location recorded this winter, generally on 15th March after the last significant storm. Altitudes and PCT Miles are approximate.

San Jacinto Peak (10810 ft): 14 inches drifted to two feet in places (was 40 inches on 15th March)

Little Round Valley (9800 ft): 9 inches ranging from 0-24 inches (was 35 inches on 15th March)

Wellman Divide (9700 ft): 2 inches, ranging from 0-8 inches (was 20 inches on 15th March)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 15 inches (was 38 inches on 15th March)

Saddle Junction/PCT Mile 179 (8070 ft): 1 inch, ranging from 0-4 inches (was 21 inches on 15th March)

Strawberry Junction/PCT Mile 183 (8050 ft): 0 inches (was 20 inches on 15th March)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inches (was 15 inches on 7th March and 12 inches on 15th March)

Idyllwild (at 5550 ft): 0 inches (was 14 inches on 7th March and 11 inches on 15th March)

UPDATE Friday 4th April 2025: the minor storm system on 2nd produced only very light snow, with 0.5 inch in Idyllwild and locations up to 7000 ft (already largely melted), 0.75 inch at Saddle Junction (PCT Mile 179), and two inches everywhere from 9000 ft up to San Jacinto Peak. Snow was so shallow that pre-existing tracks could be followed relatively easily, and I recorded a short video report as I descended the East Ridge Trail of San Jacinto Peak on 3rd (linked here). I resurveyed throughout the high country on 4th. The Pacific Crest Trail has well-traveled tracks throughout the fresh snow along its entire length in the San Jacinto mountains. Spikes are sufficient traction everywhere on the PCT and also on the main trails to the high peaks. Melting has already been remarkably rapid and will accelerate this weekend, and trail conditions are already starting to resemble those described below.

————————————-

As described in the introduction to the previous report (linked here) we are on track for one of the driest winters in recorded history for the San Jacinto high country. That said, this week is pleasantly cool and cloudy – perhaps the last vestige of winter 2024/25 – resulting in relatively firm and reliable snow conditions, ideal for brisk, efficient hiking. Largely gone is the soft, slushy postholing of last week, at least until temperatures warm again next weekend (from about 5th April onwards).

This update includes a detailed PCT-specific section (between Weather and Trail Conditions), although much of the remainder of the Report includes material relevant to thru hikers also.

Carrying spikes remains recommended everywhere above about 7500 ft, although with reliably grippy footwear, hikers with extensive experience on icy snow will find they are not required for travel on or adjacent to established tracks. Spikes remain very valuable for significant sections of the PCT, as described below. To give a sense of track conditions, although I have carried them as a precaution, I have not used spikes for my last three ascents (via various routes) of San Jacinto Peak in recent days.

Crampons are preferable on the north side of Tahquitz Peak (details below). Crampons are also a reasonable option elsewhere on the high country trails, generally above 9000 ft, but they are not required, and will become much less suitable as snow-free patches appear throughout the high country in the second week of April.

Conditions are currently unsuitable for snowshoes on established tracks due to the firmness of icy snow almost everywhere. Snowshoes may again become an option above about 9000 ft after about Monday 7th April on warm days from late morning onwards as snow softens dramatically (but by then consistent snow depths may well be too shallow in all but very sheltered areas).

Details of snow depths measured at a few sample locations on the trail system are given below. Note however that snow depth itself is very rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example – as discussed above – a firm, well-compacted track across deep snow is often much easier hiking than a less well-traveled track across just a few inches depth of angled icy snow.

The USFS gate at Humber Park reopened on 21st March, having closed on 5th March. South Ridge Road reopened on 25th March, having been closed since 10th. Black Mountain Road remains closed (to vehicle traffic only) at the gate 1.7 miles up from Highway 243 due to winter conditions. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is closed long-term for staffing/funding reasons.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 1-3 times per week (more frequently during stormy weather), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

WEATHER

A cooler, unsettled week between Saturday 29th March and Friday 4th April will include temperatures at or even below seasonal at all elevations, largely cloudy days, strong winds in the high country, and modest chances for some light precipitation.

Very light rain is possible any day in this cooler period, but is currently most likely on the afternoon and evening of Tuesday 1st and again on the afternoon of Thursday 3rd April. Total rainfall at mid elevations across the 4-5 day period is expected to be less than 0.5 inch. Dustings of 0.5-1.0 inch of snow are currently forecast as possible at higher elevations on the afternoons of 1st and 3rd April.

Temperatures start to rise steadily on Saturday 5th into the second week of April. Remaining snow will melt rapidly, and softer snow conditions will mean a return to the postholing of last week.

Idyllwild is currently at about 85% of seasonal snowfall for the water year, but only 45% of average rainfall. We will once again be dependent on an increasingly unreliable monsoon season to approach an average water year. The latest video report from National Weather Service San Diego suggests generally warmer and drier than average conditions may now persist for months (video linked here).

At San Jacinto Peak (10,810ft/3295m) on Sunday 30th March 2025 at 0845 the air temperature was 28.8°F (-2°C), with a windchill temperature of 10.8°F (-12°C), 93% relative humidity, and a fresh WNW wind sustained at 19 mph gusting to 31.0 mph.

At the Peak on Tuesday 18th March 2025 at 0925 the air temperature was 23.3°F (-5°C), with a windchill temperature of 2.6°F (-16°C), 21% relative humidity, and a potent WNW wind sustained at 25 mph gusting to 33.7 mph.

PACIFIC CREST TRAIL

All of the PCT in the San Jacinto mountains is readily passable with, crucially, suitable skills and equipment, patience, and a thorough knowledge of all possible alternates if needed. Snowmelt has been very rapid since the last storm in mid March, and is expected to continue to be fast into early April (at least). Nevertheless, I cannot overemphasize the importance of having both appropriate equipment and the right skill set for the terrain. The latter includes interpreting the snow/ice conditions, understanding your physical and mental abilities, and conservative decision making.

There is now a continuous boot track on the PCT through the entire San Jacinto mountains. However, that does not mean the hike is easy, as laborious postholing is required in many areas, and some sections – notably Miles 169-176 and Miles 185.5-191 – have consequential terrain in places that will not be suitable for some hikers depending on their equipment and experience traversing icy snow slopes.

The trail is largely clear of snow from Miles 151 (Highway 74) to about Mile 167. Limited patchy snow remains on north-facing and sheltered slopes, such as the descent to Fobes Saddle, and on the east side of Spitler Peak. There are alternates at Fobes Saddle (Mile 166) and Spitler Peak Trail (Mile 168.5) that would be good options for hikers not comfortable on the icy snow slopes ahead.

We surveyed PCT Miles 168.5-170, including the challenging north-east side of Apache Peak, on Friday 21st March, recording a short video report (linked here). Melting has been fast but sheltered north and east facing slopes between Miles 167 (Spitler Peak) and 176 (Red Tahquitz) remain partly snow-covered and require the necessary equipment and experience for such conditions.

Snow cover is largely continuous from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat), although the terrain is generally benign. Many hikers will find spikes useful on this section.

PCT hikers should not attempt to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak, even though this looks temptingly short and simple on apps and maps. This section of steeply angled (and notoriously treacherous) ice slopes remains challenging weeks after surrounding trails have melted, and currently requires crampons, ice axe, and the expertise to use that equipment.

Snow cover is becoming patchy between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is largely clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is almost continuous. Miles 181-183 are sun-exposed and are largely clear. Snow cover is largely continuous from Mile 184 through to about Mile 192. Most hikers will find spikes are very useful throughout this section.

There is currently only a moderately traveled postholing boot track through variable snow cover on the PCT along Fuller Ridge (Miles 185.5-191). This track does not accurately follow the trail in places. Extensive snow-free sections are now developing on Miles 186-186.5 and 187.5-188.3. At this time continuing north on Fuller Ridge requires the skills and comfort level to hike on angled terrain with some moderate exposure, and spikes are recommended (although not strictly essential for the experienced). Taking the Black Mountain Road alternate remains an excellent option for hikers less comfortable with the Fuller Ridge section for the next week or so.

A well established alternate from Idyllwild – avoiding Fuller Ridge – is to connect back to the PCT at about Mile 191 using Black Mountain Road. Black Mountain Road is clear of snow for the lower five miles, and then has only patchy snow cover for the upper three miles to the PCT but with an obvious track following the road through the snow patches. Mile 192 northward to Interstate 10 is clear of snow.

Although the situation improved somewhat in 2024, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed February 2025).

PCT hikers are asked to respect that overnight stays are not permitted at or near San Jacinto Peak, including in the historic shelter, to minimize impacts to a sensitive subalpine environment. Officially Mt. San Jacinto State Park permits overnight stays only in established campgrounds (Little Round Valley and Strawberry Junction are good options for thru-hikers).

TRAIL CONDITIONS

Where snow remains, tracks are in place for almost all trails. Melting has been fast since the last storm on 15th March, but will be minimal this week in cooler, cloudier weather. Conditions this week will be excellent for snow hiking, with relatively firm, reliable footings in the compacted icy snow.

Everywhere above about 7500 ft carrying spikes is recommended as established trails are now consolidated by hiker traffic and as they continue to undergo freeze-thaw cycles. As always, spikes tend to be especially useful for descending, even when they are not necessarily required for ascending. Hikers with considerable experience on snow and ice will find that spikes are generally not required on the tracks of the established trail system.

For details of specifics of downed trees, prior to the latest snow storms, see an earlier Report (linked here).

Devil’s Slide Trail [surveyed 30th March] is almost clear of snow, with just a few limited, dirty patches remaining, largely concentrated close to Saddle Junction. Most hikers will find spikes are no longer required.

The Ernie Maxwell Trail is clear of snow [surveyed 27th March].

From Saddle Junction northbound a well-defined posthole track – in areas that still have snow -continues to San Jacinto Peak through Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails [all surveyed 30th March].

The PCT heading north from Saddle Junction (a.k.a. “Angel’s Glide”) is largely clear of snow to 9000 ft. Snow cover remains about 90% from 9000 ft through Annie’s Junction and onward to near Wellman’s Cienega. Snow cover on the Wellman Trail averages only 50% [all surveyed 30th March].

The Peak Trail route [surveyed 30th March] is very well-defined, and a few small snow-free patches are starting to appear. There is now a lightly-traveled posthole track on the uppermost part of the Peak Trail, but at 10,400 ft near Miller Peak, the heavily-traveled track climbs up the East Ridge Trail route, as is traditional in winter.

The 0.4 mile section of South Ridge Trail between Chinquapin Flat/PCT Mile 177 and Tahquitz Peak [surveyed 1st April] has a single boot track to follow through the steeply angled snow, which in its steepest section does not accurately follow the trail route and has considerable underlying ice (photo above). These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for most hikers at this time. Spikes at a minimum are strongly recommended (crampons are preferable), should be accompanied by an ice axe, and, critically, adequate experience and knowledge of how to use this equipment in such terrain.

South Ridge Trail [surveyed 1st April] from the top of South Ridge Road is functionally clear of snow to Tahquitz Peak, with just a handful of tiny patches close to the peak. Spikes are no longer required. South Ridge Road is clear of snow.

Spitler Peak Trail [surveyed 27th March] is clear of snow. Storms in February-March brought down another 34 trees across this trail, but all of the small-to-medium-sized hazards were removed on 21st and 23rd March (bringing to 162 the total number of trees removed by the Trail Report from this route in the past six years). Just one very large burned cedar remains which can be a little tricky to pass, next to the first crossing of Spitler Creek (3.2 miles up from the trailhead, 1.6 miles down from the PCT).

Round Valley Trail is rapidly clearing of snow from Long Valley to Round Valley. There is a well-traveled track on largely continuous but thin icy snow from there to Wellman Divide.

Marion Mountain Trail [surveyed 29th March] is largely clear of snow below 7500 ft, averaging about 10% snow cover. From that elevation to the junction with Deer Springs Trail/PCT, snow cover averages 50%. There is a well-worn track throughout all snow patches. Some hikers will find spikes are useful, at least for descending, but steps are so well-defined through the snow that spikes are certainly no longer essential.

Deer Springs Trail [surveyed 29th March] is clear of snow from the Highway 243 trailhead to the Suicide Rock trail junction at 7000 ft. From there to Strawberry Junction (8100 ft) snow cover averages just 10% with snow patches increasing in length and frequency as you ascend. Spikes are not required as far as Strawberry Junction, even for descending. Snow cover is largely continuous from Strawberry Junction to San Jacinto Peak, although clear sections are starting to appear below 8500 ft (south of the top of the Marion Mountain Trail). The track from Strawberry Junction to the junction with Marion Mountain Trail is generally a laborious posthole track. A well-traveled track is then generally easy to follow to Little Round Valley, although it does not accurately follow the trail route in places. Above Little Round Valley there are multiple posthole/snowshoe tracks, all generally much more direct than the actual trail and not remotely following the established trail route (as is traditional in adequate snow conditions). There is one well-traveled track well north of the trail, and another well to the south, plus my very direct single posthole track straight to the Peak. Despite their challenges, all these routes do ultimately end up at San Jacinto Peak. Spikes are generally recommended at least for descending upper Deer Springs Trail, but on mornings when the icy snow is crisp and dry, they are not required.

SNOW DEPTHS

Measured on 29th March (west slope locations) and 30th March 2025 (east side). The first number gives current average depth. Strong winds accompanying storms led to extensive drifting, and there has been highly variable melting in the past week or so. The number in parentheses indicates the greatest depth for that location recorded this winter, generally on 15th March after the last significant storm. Altitudes and PCT Miles are approximate.

San Jacinto Peak (10810 ft): 16 inches drifted to 2-3 feet in places (was 40 inches on 15th March)

Little Round Valley (9800 ft): 11 inches ranging from 0-24 inches (was 35 inches on 15th March)

Wellman Divide (9700 ft): 3 inches, ranging from 0-10 inches (was 20 inches on 15th March)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 16 inches (was 38 inches on 15th March)

Saddle Junction/PCT Mile 179 (8070 ft): 1 inch, ranging from 0-5 inches (was 21 inches on 15th March)

Strawberry Junction/PCT Mile 183 (8050 ft): 0 inches (was 20 inches on 15th March)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inches (was 15 inches on 7th March and 12 inches on 15th March)

Idyllwild (at 5550 ft): 0 inches (was 14 inches on 7th March and 11 inches on 15th March)

Despite the snowfall from storms between mid February and mid March, if the San Jacinto high country receives no more snowfall this winter then 2024/25 will be the second driest winter on record for the upper elevations of these mountains (using the metric of total snowfall at San Jacinto Peak). It would be unprecedented not to get at least a few more inches of snow between now and 1st June, although remarkably we still need 40+ inches to avoid this being one of the three driest high country winters on record.

Of course, none of this will be much solace to PCT hikers postholing through melting, soft, slushy snow, or taking alternates, or both. With temperatures currently well above seasonal at all elevations until 26th March, melting will continue steadily. At mid elevations temperatures drop to around seasonal for the last four days of March into the first week of April, but temperatures remain largely above seasonal in the high country (with the exception of 28th-30th March, and 4th April). Relatively cloudy skies will be a feature of the next 7-10 days, slowing snow melt somewhat.

It was striking on Monday 24th that the PCT immediately north of Saddle Junction, a section that had an average depth of two feet of snow just nine days ago, is already rapidly clearing, with extensive bare patches in and near the trail. San Jacinto Peak has already lost more than 12 inches of snow in the same time period.

This update includes a detailed PCT-specific section (between Weather and Trail Conditions), although much of the remainder of the Report includes material relevant to thru hikers also.

We surveyed PCT Mile 169.5, the challenging north-east side of Apache Peak, on 21st March, where I recorded a short video report (linked here). Melting has been fast but sheltered north and east facing slopes between Miles 167 (Spitler Peak) and 176 (Red Tahquitz) remain snow-bound and require the necessary equipment and experience for such conditions. Since recording that video, Spitler Peak Trail has been cleared of all but one of 34 trees that came down in recent storms, so that is now a relatively hassle-free alternate.

Carrying spikes is recommended everywhere above about 7500 ft for the foreseeable future. They remain invaluable for significant sections of the PCT, although they are not strictly required. On Monday 24th and Saturday 29th I was able to hike to San Jacinto Peak via Devil’s Slide and Marion Mountains trails, respectively, without using spikes either up or down, specifically with an Alpine start on relatively firm morning snow (note that I carried spikes just in case).

Crampons are required on the north side of Tahquitz Peak (details below). Crampons are also a reasonable option elsewhere on the high country trails, generally above 9000 ft, but they are not required, and will become much less suitable as snow-free patches appear in the second week of April.

Conditions are currently reasonable for snowshoes everywhere above about 9000 ft, only on warmer days from late morning onwards as snow softens dramatically, especially on sun-exposed slopes.

Details of snow depths measured at a few sample locations on the trail system are given below. Note however that snow depth itself is very rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across deep snow is often much easier hiking than a less well-traveled track across just a few inches depth of angled icy snow.

The USFS gate at Humber Park reopened on 21st March, having closed on 5th March. South Ridge Road reopened on 25th March, having been closed since 10th. Black Mountain Road remains closed (to vehicle traffic only) at the gate 1.7 miles up from Highway 243 due to winter conditions. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is closed long-term for staffing/funding reasons.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 1-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

WEATHER

The complex sequence of minor and moderate storms that impacted the region in the first half of March is described in a previous report (linked here).

The overall pattern for the remainder of March into the first week of April is for warmer than seasonal temperatures at higher elevations, but cooling to near seasonal, with significant cloudiness, at mid elevations. Temperatures will be hot (for March) until Thursday 27th. Thereafter, 7-10 days of cooler, seasonally average temperatures are forecast for mid elevations, but temperatures will generally remain above average (and, crucially, near or above freezing) in the high country, other than brief but notable cooling on 2nd-4th April.

The last few days of March and the first week of April are expected to be partly or mostly cloudy, in contrast to recent clear, sunny days. There are possibilities for very light rain at mid elevations on the western slope (e.g., Idyllwild and the PCT) from 28th March to 4th April as a dense layer of moist marine cloud rises to at least 7000 ft elevation.

Idyllwild is currently at about 85% of seasonal snowfall for the water year, but only 45% of average rainfall. We will once again be dependent on an increasingly unreliable monsoon season to approach an average water year. The latest video report from National Weather Service San Diego suggests generally warmer and drier than average conditions may now persist for months (video linked here).

At San Jacinto Peak (10,810ft/3295m) on Monday 24th March 2025 at 0835 the air temperature was 38.1°F (3°C), with a windchill temperature of 27.0°F (-3°C), 45% relative humidity, and a remarkably steady ESE wind sustained at 13 mph gusting to 15.0 mph.

At the Peak on Tuesday 18th March 2025 at 0925 the air temperature was 19.1°F (-7°C), with a windchill temperature of -3.1°F (-20°C), 33% relative humidity, and a chilly NNW wind sustained at 15 mph gusting to 27.6 mph.

PACIFIC CREST TRAIL

All of the PCT in the San Jacinto mountains is readily passable with, crucially, suitable skills and equipment, patience, and a thorough knowledge of all possible alternates if needed. Snowmelt has been very rapid since the last storm in mid March, and is expected to continue to be fast into early April (at least). Nevertheless, I cannot overemphasize the importance of having both appropriate equipment and the right skill set for the terrain. The latter includes interpreting the snow/ice conditions, understanding your physical and mental abilities, and conservative decision making.

There is now a continuous boot track on the PCT through the entire San Jacinto mountains. However, that does not mean the hike is easy, as laborious postholing is required in many areas, and some sections – notably Miles 169-176 and Miles 185.5-191 – have consequential terrain in places that will not be suitable for some hikers depending on their equipment and experience traversing icy snow slopes.

The trail is largely clear of snow from Miles 151 (Highway 74) to about Mile 167. Some thin patchy icy snow remains on north-facing and sheltered slopes, such as the descent to Fobes Saddle, and on the east side of Spitler Peak. There are alternates at Fobes Saddle (Mile 166) and Spitler Peak Trail (Mile 168.5) that would be good options for hikers not comfortable on the icy snow slopes ahead.

We surveyed PCT Miles 168.5-170, including the challenging north-east side of Apache Peak, on Friday 21st March, recording a short video report (linked here). Melting has been fast but sheltered north and east facing slopes between Miles 167 (Spitler Peak) and 176 (Red Tahquitz) remain significantly snow-covered and require the necessary equipment and experience for such conditions.

Snow cover is continuous from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat), although the terrain is generally benign. Many hikers will find spikes useful on this section.

PCT hikers should not attempt to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak, even though this looks temptingly short and simple on apps and maps. This section of steeply angled (and notoriously treacherous) ice slopes remains challenging weeks after surrounding trails have melted, and currently requires crampons, ice axe, and the expertise to use that equipment.

Snow cover is thinning and just starting to become patchy between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is already starting to clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is continuous. Miles 181-183 are sun-exposed and are clearing of snow very quickly. Snow cover is largely continuous from Mile 183.5 through to about Mile 192. Most hikers will find spikes are very useful throughout this section.

There is currently only a lightly traveled postholing boot track through moderate snow cover on the PCT along Fuller Ridge (Miles 185.5-191). This track does not accurately follow the trail in places. Snow-free patches are now developing on Miles 186-186.5 and 187.5-188.3. At this time continuing north on Fuller Ridge requires the skills and comfort level to hike on angled terrain with some moderate exposure, and spikes are recommended (although not strictly essential for the experienced). Taking the Black Mountain Road alternate is an excellent option for hikers uncomfortable with the Fuller Ridge section for the next week or two.

In recent years a myth has periodically circulated on PCT social media that going up and over San Jacinto Peak somehow avoids Fuller Ridge. This is erroneous and potentially dangerous. Whether you remain on the PCT northbound (going around at lower elevation via Strawberry Junction, Mile 183) or leave the PCT at Annie’s Junction (Mile 180.8) to go up to San Jacinto Peak and then down the west side to reconnect to the PCT at about Mile 185.5, you still have to hike Fuller Ridge (Miles 185.5-190.5). It is possible to do the former route more safely by leaving the PCT at Strawberry Junction and descending Deer Springs Trail, which is largely clear of snow below Strawberry Junction, back into Idyllwild.

A well established alternate from Idyllwild – avoiding Fuller Ridge – is to connect back to the PCT at about Mile 191 using Black Mountain Road. Black Mountain Road is clear of snow for the lower five miles, and then has patchy snow cover for the upper three miles to the PCT but with an obvious track following the road through the snow patches. Mile 192 northward to Interstate 10 is functionally clear of snow, and patchy snow on Miles 191-192 will clear in the next week.

Although the situation improved somewhat in 2024, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed February 2025).

PCT hikers are asked to respect that overnight stays are not permitted at or near San Jacinto Peak, including in the historic shelter, to minimize impacts to a sensitive subalpine environment. Officially Mt. San Jacinto State Park permits overnight stays only in established campgrounds (Little Round Valley and Strawberry Junction are good options for thru-hikers).

TRAIL CONDITIONS

Tracks are now in place for most major trails, although above 7500 ft they generally require significant postholing through softening, melting snow, especially for the next 1-2 weeks.

Everywhere above about 7000 ft carrying spikes is recommended as established trails become consolidated by hiker traffic and as they undergo freeze-thaw cycles (more thaw than freeze recently). As always, spikes tend to be especially useful for descending, even when they are not necessarily required for ascending.

Snow depths and conditions are suitable for snowshoeing everywhere in the high country above 9000 ft, best above 9500 ft. On sun-exposed slopes that snow is softening and becoming “weighty” by mid morning (if not sooner) making for slower and less enjoyable snowshoeing. The same however is true for postholing.

For details of specifics of downed trees, prior to the latest snow storms, see an earlier Report (linked here).

Devil’s Slide Trail is functionally clear of snow below 7400 ft, with just a few minor patches remaining. Above that elevation, snow cover averages about 60%. Icy snow patches are lengthy around the upper switchbacks (switchbacks 6-8 for those very familiar with the trail) and close to Saddle Junction. Most hikers will find spikes can be useful, especially for descending.

The Ernie Maxwell Trail is clear of snow [updated 27th March].

From Saddle Junction northbound a well-defined posthole track continues to San Jacinto Peak via Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails.

The PCT heading north from Saddle Junction (a.k.a. “Angel’s Glide”) is clearing rapidly of snow on its sun-exposed sections, especially the lower half below 8500 ft. Snow cover is >95% and the track is a fairly laborious posthole mess from 9000 ft through Annie’s Junction and onward on the Wellman Trail to Wellman Divide.

The Peak Trail route is very well-defined, and due to volume of traffic, averages less uneven than the Wellman Trail. At 10,400 ft near Miller Peak, the track climbs up the East Ridge Trail route, as is traditional in winter (the uppermost Peak Trail still has no tracks to follow).

The 0.4 mile section of South Ridge Trail between Chinquapin Flat/PCT Mile 177 and Tahquitz Peak [updated 26th March] has no track to follow through the steeply angled snow, with substantial underlying ice. These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for most hikers at this time. Crampons are required, always accompanied by an ice axe, and, critically, adequate knowledge of how to use this equipment.

South Ridge Trail [updated 26th March] from the top of South Ridge Road to Tahquitz Peak is clear of snow to Old Lookout Flat (7600 ft). Snow cover averages only 10% from there to Tahquitz Peak, with patches increasing in frequency and length close to the peak. Most hikers will not require spikes, but they can be useful for descending the uppermost switchbacks. South Ridge Road is clear of snow.

Spitler Peak Trail is clear of snow. Storms in February-March brought down another 34 trees across this trail, but all of the small-to-medium-sized hazards were removed on 21st and 23rd March (bringing to 162 the total number of trees removed by the Trail Report from this route in the past six years). Just one very large burned cedar remains which can be a little tricky to pass, next to the first crossing of Spitler Creek (3.2 miles up from the trailhead, 1.6 miles down from the PCT).

Round Valley Trail has a well-traveled track on largely continuous but thin icy snow from Long Valley/Tram to Wellman Divide.

Marion Mountain Trail is largely clear of snow below 7500 ft, averaging about 10% snow cover. From that elevation to the junction with Deer Springs Trail/PCT, snow cover average 50%. There is a well-worn track throughout all snow patches. Some hikers will find spikes are useful, at least for descending, but steps are so well-defined through the snow that spikes are certainly no longer essential.

Deer Springs Trail is functionally clear of snow from the Highway 243 trailhead to the Suicide Rock trail junction at 7000 ft. From there to Strawberry Junction (8100 ft) snow cover averages just 20% with snow patches increasing in length and frequency as you ascend. Spikes are not required as far as Strawberry Junction, even for descending. Snow cover is largely continuous from Strawberry Junction to San Jacinto Peak, although clear sections are starting to appear below 8500 ft (south of the top of the Marion Mountain Trail). The track from Strawberry Junction to the junction with Marion Mountain Trail is generally a laborious posthole track. A well-traveled track is then generally easy to follow to Little Round Valley, although it does not accurately follow the trail route in places. Above Little Round Valley there are multiple posthole/snowshoe tracks, all generally much more direct than the actual trail and not remotely following the established trail route (as is traditional in adequate snow conditions). There is one well-traveled track well north of the trail, and another well to the south, plus my very direct single posthole track straight to the Peak. Despite their challenges, all these routes do ultimately end up at San Jacinto Peak. Spikes are generally recommended at least for descending upper Deer Springs Trail, but on mornings when the icy snow is crisp and dry, they are not required.

SNOW DEPTHS

Measured on 24th March 2025. The first number gives current average depth. Due to strong winds accompanying recent storms there has been extensive drifting. The number in parentheses indicates the greatest depth for that location recorded this winter, generally on 15th March after the last significant storm. Altitudes and PCT Miles are approximate.

San Jacinto Peak (10810 ft): 25 inches (was 40 inches on 15th March) drifted to 3-4 feet in places

Wellman Divide (9700 ft): 7 inches (was 20 inches on 15th March)

Annie’s Junction/approx. PCT Mile 180.8 (9020 ft): 27 inches (was 38 inches on 15th March)

Saddle Junction/approx. PCT Mile 179 (8070 ft): 4 inches (was 21 inches on 15th March)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inches (was 15 inches on 7th March and 12 inches on 15th March)

Idyllwild (at 5550 ft): 0 inches (was 14 inches on 7th March and 11 inches on 15th March)

UPDATE Friday 21st March 2025: We surveyed PCT Mile 169.5, the challenging north-east side of Apache Peak, this morning, where I recorded a short video report (linked here). Melting has been fast but sheltered north and east facing slopes between Miles 167 (Spitler Peak) and 176 (Red Tahquitz) remain snow-bound and require the necessary equipment and experience for such conditions.

I have heavily revised this report since it was first issued on 15th March, having now re-surveyed all of the high country and much of the PCT. A dedicated PCT section is below (between Weather and Trail Conditions below).

The San Jacinto mountains were impacted by back-to-back storms last week, a moderate snow storm all day on Thursday 13th March, immediately followed by a second minor system on Friday 14th. These represented the eleventh and twelfth storm systems of this winter (for comparison, the previous two winters had 26 and 28 storm systems, respectively). Further minor precipitation on 17th produced 0.17 inch of rain in Idyllwild but no new snow in the high country.

Although of shorter duration, the system on 13th March was broadly similar to that on 5th-7th March, a cold atmospheric river with snow dusting as low as 3500 ft, and with significant depth of snow everywhere above about 4500 ft elevation. This had an immediate major impact on all trails in the San Jacinto mountains, including the entire PCT section from Miles 151 (Highway 74 crossing) to 197 (above Snow Creek village).

Although significant snow conditions will persist in the high country into April, thru hikers in particular should note that melting is expected to be rapid. Temperatures generally well above seasonal are now forecast for much of the remainder of March at both mid and upper elevations. Based on my detailed observations in the past decade, it is normal for the high country to lose 12 inches of snow per week in March-April, assuming average sun exposure and temperatures.

Details of snow depths measured at a few sample locations on the trail system are given below. Note however that snow depth itself is very rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across deep snow is often much easier hiking than a less well-traveled track across just a few inches depth of angled icy snow.

The final combined new snow total form this latest storm sequence at San Jacinto Peak was 17 inches, for a current total depth of 40 inches, while snow accumulation in Idyllwild (at 5550 ft) was an impressive 11 inches (nine on 13th, followed by two inches on 14th). Ultimately, both storms on 13th and 14th produced somewhat less snow than forecast, especially at higher elevations.

I recorded a short video at San Jacinto Peak late morning on Saturday 15th discussing general conditions at that time (linked here).

Conditions are currently suitable for snowshoes everywhere above about 8000 ft. This elevation will continue to rise steadily this month. With rapid melting, conditions for snowshoes will deteriorate quickly below about 8000 ft, despite the snow depths. Nevertheless snowshoes will remain the best option even in the soft, wet, melting snow.

Carrying spikes is recommended everywhere above about 7000 ft for the foreseeable future. Crampons are required on the north side of Tahquitz Peak (details below). At this time the snow is generally too soft to require crampons elsewhere in the high country, but that may well change with freeze-thaw cycles and compaction over the coming days.

I broke trail on 15th March from Humber Park to San Jacinto Peak, accurately following the route via Devil’s Slide Trail, a short section of the PCT, and the Wellman, Peak, and East Ridge trails. Andrew “Bones” Simpson joined me for the final mile above 10,100 ft. These tracks will hold up well given a relatively mild, sunny forecast, although melting and ice falling from trees will deteriorate them.

On my descent late morning on Saturday 15th, I have never seen the snow conditions deteriorate so quickly (having surveyed >200 storms in the past decade). Within hours, lovely firm, fresh, powder had softened to wet, heavy, deteriorating snow, even above 10,000 ft. By early afternoon, sections of lower Devil’s Slide Trail were linear patches of slush, where six hours earlier it had be unblemished powder.

On Tuesday 18th I ascended San Jacinto Peak via the east side (Devil’s Slide, Wellman, Peak, and East Ridge trails) and descended the west side via Deer Springs Trail, carrying spikes and snowshoes. This facilitated survey of the highest parts of the PCT in the San Jacinto mountains (roughly Miles 179-181 and 185.5-183) plus several side trails. I was able to ascend barebooting on my well-traveled snowshoe track to 10,300 ft on the Peak Trail before needing spikes to continue. I then wore spikes all the way down Deer Springs Trail to about 7500 ft.

The USFS gate at Humber Park reopened on 21st March, having been closed since 5th March. Even when closed there are nine legal parking spaces immediately below the gate. South Ridge Road has been closed since 10th March due to seasonal conditions. Black Mountain Road is also closed (to vehicle traffic only) at the gate 1.7 miles up from Highway 243 due to winter conditions. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is closed long-term for staffing/funding reasons.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

WEATHER

Seasonally warm days prior to the arrival of these latest storms stimulated significant melting, with, for example, most areas of Fern Valley and Idyllwild below 6500 ft almost completely clear of snow.

A minor storm on Tuesday 11th, starting pre-dawn and lasting for most of the day, produced mainly light rain at mid elevations (0.3 inch in Idyllwild), and a dusting of 1-2 inches of snow in the high country. That brief minor storm ran almost seamlessly into a cold atmospheric river on 13th March, similar to the storm of 5th-7th March, producing 9-15 inches of snow everywhere above about 5000 ft, and dusting as low as 3500 ft. Finally, a minor atmospheric river immediately followed that on 14th, producing less snow than forecast (only two inches throughout the mid and higher elevations), with a little light drizzle also below 7000 ft.

The overall pattern for the remainder of March is for warmer than seasonal temperatures, getting progressively warmer as the month continues. In addition, most days will be cloudless and sunny, further accelerating snow melt, especially on sun-exposed slopes. Temperatures will be hot (for March) on 23rd-27th.

An atmospheric river system passed largely to our north on the evening of Monday 17th March, producing no more that limited light rain at mid elevations (017 inch in Idyllwild) and evidence of drizzle to 9500 ft, but no new snowfall at higher elevations.

At San Jacinto Peak (10,810ft/3295m) on Tuesday 18th March 2025 at 0925 the air temperature was 19.1°F (-7°C), with a windchill temperature of -3.1°F (-20°C), 33% relative humidity, and a chilly NNW wind sustained at 15 mph gusting to 27.6 mph.

At the Peak on Saturday 15th March 2025 at 1010 the air temperature was 27.4°F (-3°C), with a windchill temperature of 9.3°F (-13°C), 55% relative humidity, and a frigid NNW wind sustained at 14 mph gusting to 27.9 mph.

PACIFIC CREST TRAIL

All of the PCT in the San Jacinto mountains is readily passable with, crucially, suitable skills and equipment, patience, and a thorough knowledge of all the possible alternates if needed. Snowmelt is expected to be rapid for the remainder of March. I cannot overemphasize the importance of having both appropriate equipment and the right skill set for the terrain. The latter includes interpreting the snow/ice conditions, understanding your physical and mental abilities, and conservative decision making. Some of these challenges may actually increase briefly over the next week or so with temperatures fluctuating either side of freezing at the highest elevations and highly variable snowmelt.

There is now a continuous boot track on the PCT through the entire San Jacinto mountains. However, that does not mean the trail is easy to follow, laborious postholing is required in many areas, and some sections – notably Miles 169-176 and Miles 185.5-191 – have consequential terrain that will not be suitable for many hikers depending on their equipment and experience traversing icy snow slopes.

The trail was largely covered in thin snow from Miles 151 (Highway 74) to about Mile 167 as of 15th March. However this has already melted rapidly. Some thin patchy icy snow remains on north-facing and sheltered slopes. There are alternates at Fobes Saddle (Mile 166) and Spitler Peak Trail (Mile 168.5) that would be good options for hikers not comfortable on the icy snow slopes ahead.

We surveyed PCT Mile 168.5-170, including the challenging north-east side of Apache Peak, on Friday 21st March, recording a short video report (linked here). Melting has been fast but sheltered north and east facing slopes between Miles 167 (Spitler Peak) and 176 (Red Tahquitz) remain significantly snow-covered and require the necessary equipment and experience for such conditions.

Snow cover is continuous from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat), although the terrain is generally benign. Many hikers will find spikes useful on this section.

PCT hikers should not attempt to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak, even though this looks temptingly simple on apps and maps. This section of steeply angled (and notoriously treacherous) ice slopes remains challenging weeks after surrounding trails have melted, and currently requires crampons, ice axe, and the expertise to use that equipment.

Snow cover is thinning and will soon become patchy between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is already starting to clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is continuous. Miles 181-183 are sun-exposed and will clear of snow in the next week. Snow cover is continuous from Mile 183.5 through to about Mile 195. Spikes are useful throughout this section.

There is currently only a single postholing boot track through moderate snow cover on the PCT along Fuller Ridge (Miles 185.5-191). This track does not accurately follow the trail in places. At this time continuing north on Fuller Ridge requires the skills and comfort level to hike on angled terrain with some moderate exposure, and spikes are required. Taking the Black Mountain Road alternate is recommended for the majority of hikers for the next week or two.

In recent years a myth has periodically circulated on PCT social media that going up and over San Jacinto Peak somehow avoids Fuller Ridge. This is erroneous and potentially dangerous. Whether you remain on the PCT northbound (going around at lower elevation via Strawberry Junction, Mile 183) or leave the PCT at Annie’s Junction (Mile 180.8) to go up to San Jacinto Peak and then down the west side to reconnect to the PCT at about Mile 185.5, you still have to hike Fuller Ridge (Miles 185.5-190.5). It is possible to do the former route more safely by leaving the PCT at Strawberry Junction and descending Deer Springs Trail, which is largely clear of snow below Strawberry Junction, back into Idyllwild.

A well established alternate from Idyllwild – avoiding Fuller Ridge – is to connect back to the PCT at about Mile 191 using Black Mountain Road. Black Mountain Road is rapidly clearing of snow for the lower five miles, and then has continuous snow cover for the upper three miles to the PCT but following the road through the snow patches is obvious. Mile 195 northward to Interstate 10 is functionally clear of snow, and Miles 191-195 will clear in the next week or so.

Although the situation improved somewhat in 2024, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed February 2025).

PCT hikers are asked to respect that overnight stays are not permitted at or near San Jacinto Peak, including in the historic shelter, to minimize impacts to a sensitive subalpine environment. Officially Mt. San Jacinto State Park permits overnight stays only in established campgrounds (Little Round Valley and Strawberry Junction are good options for thru-hikers).

TRAIL CONDITIONS

Tracks are now in place for most major trails, although they may require significant postholing through softening, melting snow, especially for the next 1-2 weeks.

Snow depths and conditions are suitable for snowshoeing everywhere in the high country. Melting is already well underway and it has been noticeable on sun-exposed slopes that snow is softening and becoming “weighty” by mid morning (if not sooner) making for slower and less enjoyable snowshoeing. The same is true for postholing.

Everywhere above about 7000 ft carrying spikes is recommended as established trails become consolidated by hiker traffic and as they undergo freeze-thaw cycles. As always, spikes tend to be especially useful for descending, even when they are not necessarily required for ascending.

For details of specifics of downed trees, prior to the latest snow storms, see an earlier Report (linked here).

Devil’s Slide Trail has a very well defined track to Saddle Junction. Snow is rapidly clearing below 7000 ft.

The Ernie Maxwell Trail is largely clear of snow, and has a very well-defined track through the remaining patches of shallow icy snow. Snow patches are distributed throughout the length of the trail, but become longer and more frequent on the upper trail (closer to Humber Park). Some hikers may find spikes are useful, especially for the upper trail.

From Saddle Junction northbound a well-defined snowshoe track continues to San Jacinto Peak via Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails. Due to spindrift, the tracks can be periodically obscure on some exposed slopes closest to the Peak.

The 0.4 mile section of South Ridge Trail between Chinquapin Flat/PCT Mile 177 and Tahquitz Peak, that has attracted much media attention recently, has no track to follow through the steeply angled snow, with substantial underlying ice. These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for most hikers at this time. Crampons are required, always accompanied by an ice axe, and, critically, adequate knowledge of how to use this equipment. Snowshoes are not recommended due to the underlying angled ice.

Spitler Peak Trail [updated 23rd March] is clear of snow. Unfortunately storms in February-March brought down another 34 trees across this trail. All of the small-to-medium-sized obstacles were removed on 21st and 23rd March (bringing to 162 the total number of trees removed by the Trail Report from this route in the past six years). One very large burned cedar remains, right by the first crossing of Spitler Creek (3.2 miles up from the trailhead).

Round Valley Trail has a well-traveled track on continuous moderate icy snow from Long Valley/Tram to Wellman Divide.

South Ridge Trail from the top of South Ridge Road to Tahquitz Peak has a moderately-traveled track to follow through moderate icy snow for about one mile. There is then a lightly-traveled posthole track on to Old Lookout Flat (7600 ft). There is currently no track to follow from there to Tahquitz Peak (as of 17th March). Spikes are not required for ascending, but some hikers will find them useful for descending.

Marion Mountain Trail has a well-defined snowshoe and posthole track throughout, but the track does not always accurately follow the actual trail route. Spikes are recommended, at least for descending.

Deer Springs Trail is rapidly clearing from the Highway 243 trailhead to the Suicide Rock trail junction at 7000 ft. From there to Strawberry Junction (8100 ft) snow cover averages 90% with snow patches increasing in length and frequency as you ascend. Spikes were not required even for descending by the afternoon of 18th. Snow cover is continuous from Strawberry Junction to San Jacinto Peak, although a few small patches are starting to appear below 8500 ft (south of the top of the Marion Mountain Trail). The track from Strawberry Junction to the junction with Marion Mountain Trail is a laborious posthole track. An adequate snowshoe track is then generally easy to follow to Little Round Valley, although it does not follow the trail route in many places. Above Little Round Valley there is only a single. very circuitous, snowshoe track (which does not remotely follow the established trail route). However the compaction of the track is useful for negotiating the unconsolidated snow, and it does ultimately end up at San Jacinto Peak. Spikes are recommended at least for descending upper Deer Springs Trail, but snowshoes are preferable on warm days (i.e. daily now until the end of March).

SNOW DEPTHS

Measured on 15th March 2025. The first number gives total average depth. Due to strong winds accompanying recent storms there has been extensive drifting. The number in parentheses indicates the new snowfall in the storms on 13th-14th March. Altitudes and PCT Miles are approximate.

San Jacinto Peak (10810 ft): 40 inches (17 inches new snow), drifted to 4-5 feet deep in places

Wellman Divide (9700 ft): 20 inches (14 inches new snow), heavily melted from 8th-12th March

Annie’s Junction/approx. PCT Mile 180.8 (9020 ft): 38 inches (12 inches new snow)

Saddle Junction/approx. PCT Mile 179 (8070 ft): 21 inches (13 inches new snow)

Devil’s Slide Trail at Humber Park (6550 ft): 12 inches (12 inches new snow, already rapidly melting by late morning on 15th)

Idyllwild (at 5550 ft): 11 inches (11 inches new snow, already largely melted on 15th)

The eleventh storm of winter 2024/25 – forecast to produce the most precipitation this winter – is moving across the San Jacinto mountains between Thursday 13th and Friday 14th March 2025.

Please check this page for periodic updates – the most recent is at the top – throughout the multiple day storm sequence. The next comprehensive Report update, summarizing conditions during and after the storm, is planned for late on Saturday 15th March.

UPDATE Friday 14th March at 1600

Snowfall has been very light for much of the day at all elevations, with only 1.5 inches accumulating in Idyllwild, and no more than two inches at both Long Valley (8500 ft) and San Jacinto Peak (10,810 ft). Total accumulation at the Peak is now 40-45 inches, and 10-12 inches in Idyllwild (although slow melting is already underway this afternoon).

UPDATE Friday 14th March at 1035

After a clear night, light snow started again just after 0800 this morning. Accumulation rates are slow at both high and mid elevations, barely 0.25 inch/hour. This snowfall is forecast to continue most of today, with 3-4 inches expected at all elevations above about 5000 ft. There was significant melting overnight and this morning below 5000 ft, with snow cover now thin and patchy at 4000-4500 ft.

UPDATE Thursday 13th March at 1925

Total snow accumulation from the storm today has been 9.0 inches in Idyllwild, with snowfall rates dropping to about 0.5 inch/hour for much of the afternoon, then stopping before dusk. Storm total at San Jacinto Peak is 13-14 inches, for a total depth just over 40 inches.

A secondary storm tomorrow is forecast to be accompanied by very strong winds (and hence severe drifting) in the high country. Light snowfall throughout most of the daylight hours on Friday will include 3-4 inches at the highest elevations, with 4-6 inches at mid elevations (such as Idyllwild), and with the freeze level remaining around 4000 ft.

UPDATE Thursday 13th March at 1025

Fresh snowfall at San Jacinto Peak since last night has been about 10 inches, for a current total depth near 40 inches. Long Valley (8500 ft) has added 7-8 inches this morning.

Rainfall in the early hours of the morning in Idyllwild (at 5550 ft) was 0.37 inch by 0700, having turned to snow around 0630. Snowfall rates have neared an impressive two inches per hour, with 6.0 inches accumulating between 0630-1000.

With significant fresh snowfall now down below 4500 ft elevation, almost all the PCT in the San Jacinto mountains (Miles 151-197) is now covered with at least several inches of fresh snowfall. This will make for heavy postholing everywhere, even below 7000 ft, and snowshoes would be ideal above that elevation (potentially much lower).

Further significant snow is expected throughout today and again on Friday. That said, melting will be rapid at all elevations with temperatures abruptly swinging to above seasonal by Sunday 16th, and remaining (relatively) warm for much of next week.

UPDATE Wednesday 12th March 2025: I am not updating the main report until Saturday 15th given the dramatic changes expected in the next couple of days. I recorded a short video report from Saddle Junction (PCT Mile 179, 8100 ft elevation) this morning, to give a feel for current conditions, discussing the challenging next couple of days, and the encouraging news for thru hikers for the remainder of March (video linked here). The storm over 13th-14th March is expected to be very similar to the one described below last week.

UPDATE Tuesday 11th March 2025: light precipitation most of the day produced 0.29 inch of rain in Idyllwild (at 5550 ft), light snow with no significant accumulation in Pine Cove (6200 ft), two inches of snow at Saddle Junction (8100 ft) and at San Jacinto Peak (10,810 ft).

UPDATE Monday 10th March 2025: As expected, melting has been rapid and judging by our hike on a lengthy section of the PCT today, Miles 151-167 are largely clear of snow. North and east facing slopes, such as the PCT around Spitler Peak, still retain moderate depth snow. Options for nobo PCT hikers would be to leave the trail at Fobes Trail (Mile 166) or at Spitler Peak Trail (Mile 168.5). Miles 169-177 require crampons and ice axe, and the time and energy for miles of postholing. Conditions will change again very soon, with rain and/or snow (depending on elevation) on 11th, and a significant snow storm (similar to the one on 5th-7th described below) on 13th.

——————————

This is a summary of trail conditions following a moderate snow storm spread across nearly 36 hours from the afternoon of Wednesday 5th into the early hours of Friday 7th March. This update is intentionally brief because (i) with a weekend imminent, details of which trails have been traveled may change dramatically in the next day or two, (ii) rapid warming will result in equally rapid snow melt, especially below about 7500 ft, and (iii) further rounds of significant precipitation are forecast for the next ten days, which will change conditions yet again.

Ultimately this latest atmospheric river was cold, with snow dusting as low as 3500 ft, and with 12 inches or more of snow everywhere above 4500 ft elevation. This has obviously had a dramatic impact on all trails in the San Jacinto mountains, including the entire PCT section from Miles 151 (Highway 74 crossing) to 197 (above Snow Creek village).

Details of snow depths for select locations are given below. The final storm total at San Jacinto Peak was 18 inches, for a current total depth of about 27 inches, while snow accumulation in Idyllwild (at 5550 ft) was an impressive 14 inches. Snow depths at almost all other locations above 5000 ft fell somewhere in the range of 14-18 inches.

I recorded a short video (linked here) giving a feel for the gorgeous conditions at San Jacinto Peak early on the morning of Friday 7th.

Initially the storm system was very mild on arrival on Wednesday 5th, with drizzle all the way to San Jacinto Peak, although thankfully it quickly turned to snow. Mid elevations received reasonable rain (0.78 inch in Idyllwild) before it turned to snow around first light on Thursday 6th.

Conditions are currently excellent for snowshoes everywhere above about 5000 ft, potentially lower in places. Rapid melting is already underway, and the next three days are forecast to be relatively warm before further precipitation arrives in the early hours of Tuesday 11th. Consequently conditions for snowshoes will deteriorate quickly below about 7000 ft, despite the snow depths.

Therefore, carrying spikes is recommended everywhere above about 5000 ft for the foreseeable future. Crampons are required on the north side of Tahquitz Peak (details below). At this time the snow is generally too soft to require crampons elsewhere, but that may well change with freeze-thaw cycles and compaction over the coming days.

For anyone interested in snowshoeing (or postholing perhaps) to San Jacinto Peak this weekend from Humber Park, I broke trail on 7th March accurately following the route via Devil’s Slide Trail, a short section of the PCT, and the Wellman, Peak, and East Ridge trails. These tracks should hold up relatively well as strong winds are not forecast again until next week.

Into the second half of March at least, hikers must be prepared for genuine winter conditions in the high country, with temperatures near or below freezing, and generally well (or even far) below freezing when considering wind chill effects (see below for my recent weather observations from San Jacinto Peak).

The USFS gate at Humber Park closed on 5th March. Even when closed there are nine legal parking spaces immediately below the gate. This weekend “road closed” signs will likely be in place at the junction with Forest Drive, further complicating parking. South Ridge Road closed on 10th March due to seasonal conditions, as did Black Mountain Road at the gate 1.7 miles up from Highway 243. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is closed long-term from maintenance reasons.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (even more frequently during storms), Tahquitz Peak and area 1-3 times per week, plus a wide variety of other trails on intervening days.

WEATHER

After seasonally warm days on 9th and 10th, which will stimulate significant melting, a minor storm is forecast for Tuesday 11th, starting pre-dawn and lasting for most of the day. A relatively warm system will likely produce mainly light rain (<0.5 inch) at mid elevations, with a tentative forecast for 1-3 inches of snow in the high country.

That brief minor storm will run almost seamlessly into a moderate storm forecast for 12th-13th March. This will be a colder atmospheric river, similar to the storm of 5th-7th March, with a snow level potentially down to 4000 ft again. Mid elevations (e.g., Idyllwild) are currently expected to receive 4-8 inches of snow. High country snow estimates have ranged from 15-30 inches, with the lower end of that range currently favored by most recent forecasts.

Yet another storm system is tentatively forecast for 17th-18th March. Precipitation amounts and exact timing are uncertain this far in advance, but 6-18 inches of snow are again possible for the high country.

At San Jacinto Peak (10,810ft/3295m) on Friday 7th March 2025 at 0620 the air temperature was 12.8°F (-11°C), with a windchill temperature of -6.0°F (-21°C), 100% relative humidity, and a light due North wind sustained at 3 mph gusting to 9.8 mph.

At the Peak on Wednesday 5th March 2025 at 1550 the air temperature was 29.8°F (-1°C), with a windchill temperature of 15.4°F (-9°C), 98% relative humidity, and a frigid SW wind sustained at 8 mph gusting to 18.6 mph.

TRAIL CONDITIONS

Trails are obscured by moderate depth snow everywhere above about 4500 ft. Most of the established trails do not have tracks to follow at this time. Cautious navigation is critical everywhere.

Snow depths and conditions are excellent for snowshoeing everywhere in the high country, and, at least temporarily, at mid elevations also. Melting was already underway by late morning on 7th below about 8500 ft, and it was noticeable on sun-exposed slopes that the powder was already softening and becoming “weighty”, making for slower and less enjoyable snowshoeing. The same would be true for postholing.

Everywhere above about 5000 ft carrying spikes is recommended as established trails become consolidated by hiker traffic and as they undergo freeze-thaw cycles. As always, spikes tend to be especially useful for descending, even when they are not necessarily required for ascending.

For details of specifics of downed trees, prior to this latest snow storm, see an earlier Report (linked here).

Details of snow depths measured at a few sample locations on the trail system are given below. Note however that snow depth itself is very rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across deep snow is often much easier hiking than a poorly defined track across just a few inches depth of angled icy snow.

Devil’s Slide Trail has a well-traveled track through moderate depth snow to about 7500 ft, beyond which, at the time of writing, only my snowshoe tracks continue to Saddle Junction.

The Ernie Maxwell Trail did not have a track through the moderate depth snow at its upper end (near Humber Park) as of Saturday 8th March.

From Saddle Junction northbound a posthole track continues to San Jacinto Peak via Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails. Due to spindrift, the tracks may be obscure on some exposed slopes closest to the Peak.

The 0.4 mile section of South Ridge Trail between Chinquapin Flat/PCT Mile 177 and Tahquitz Peak, that has attracted much media attention recently, has no track to follow through the steeply angled snow, with substantial underlying ice. These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for most hikers at this time. Crampons are required, always accompanied by an ice axe, and, critically, adequate knowledge of how to use this equipment. Snowshoes are not recommended due to the underlying angled ice.

SNOW DEPTHS

Measured on 7th March 2025. The first number gives total average depth. Due to very strong winds accompanying the most recent storm system there was extensive drifting. The number in parentheses indicates the new snowfall in the storm on 5th-7th March. Altitudes and PCT Miles are approximate.

San Jacinto Peak (10810 ft): 27 inches (17.5 inches new snow, drifts in places to 40 inches deep)

Wellman Divide (9700 ft): 17 inches (14 inches new snow)

Annie’s Junction/approx. PCT Mile 180.8 (9020 ft): 28 inches (17 inches new snow)

Saddle Junction/approx. PCT Mile 179 (8070 ft): 14 inches (13 inches new snow)

Devil’s Slide Trail at Humber Park (6550 ft): 15 inches (15 inches new snow, already rapidly melting by noon on 7th)

Idyllwild (at 5550 ft): 14 inches (14 inches new snow, already melting on 7th)

Only the ninth storm of winter 2024/25 – but forecast to be one of the most notable for expected precipitation – is moving across the San Jacinto mountains between Wednesday 5th and Friday 7th March 2025.

Please check this page for periodic updates – the most recent is at the top – throughout the multiple day storm sequence. The next comprehensive Report update, summarizing conditions during and after the storm, may be published late on Friday 7th March.

UPDATE Friday 7th March at 0500

Final storm total at San Jacinto Peak is 18 inches, for a current total depth of about 27 inches (although variable due to extensive drifting, and up to three feet deep in places).

I recorded a short video (linked here) giving a feel for the gorgeous conditions at San Jacinto Peak early this morning.

Snow depth in Idyllwild (at 5550 ft) is an impressive 14 inches.

UPDATE Thursday 6th March at 2030

Snow depth at San Jacinto Peak is now around 22 inches, with 13 inches the current storm total. The lovely fluffy powder is ideal for snowshoeing. Several more inches are expected tonight.

Current accumulation is an impressive 8-9 inches in Idyllwild, and it continues to snow gently.

With significant snowfall now down below 5000 ft elevation, almost all the PCT in the San Jacinto mountains (Miles 151-196) are now covered with at least several inches of fresh snowfall. This will make for heavy postholing below 7000 ft, and snowshoes would be ideal above that elevation (potentially much lower) . Melting will be rapid at mid elevations this weekend, but further snow is expected next week.

UPDATE Thursday 6th March at 1730

After several hours of minimal snow at all elevations, snowfall has become markedly heavier in the past three hours, with larger flake size. Storm total is now 11 inches at San Jacinto Peak, accumulating at one inch per hour.

Snow depth in Idyllwild in Idyllwild is 5.5 inches at 5550 ft, following 0.78 inch of rain overnight.

UPDATE Thursday 6th March at 1100

Light snow in the mid elevations has accumulated to 1.25 inches in Idyllwild (5550 ft) and 2-3 inches in Pine Cove (6200 ft).

Snow at San Jacinto Peak is tiny rounded grains which consequently are struggling to accumulate to notable depth, another two inches this morning, for a current storm total of seven inches. Long Valley has about half that, roughly 3.5-4 inches.

The heaviest snowfall is forecast for this afternoon and evening, potentially doubling the current storm totals.

UPDATE Thursday 6th March at 0730

Fresh snowfall at San Jacinto Peak overnight was four inches, for a storm total of five, and a total depth of about 14 inches. Long Valley (8500 ft) added about three inches, for a total accumulation of about 8 inches.

Snow level is now below 5000 ft elevation, meaning that almost all the PCT in the San Jacinto mountains (at least Miles 151-195) will be covered with fresh snowfall.

Rainfall in Idyllwild at 5550 ft was 0.78 inch by 0700, having turned to snow around 0600 and already accumulating 0.75 inch. Rainfall generally at mid elevations (up to 6500 ft) was 0.8-1.0 inch throughout the western side of the mountain range, with much less at eastern locations.

UPDATE Wednesday 5th March at 1920

Light drizzle started at about 1400 at mid and upper elevations. Yes, sadly it was warm enough (at just below freezing) to rain as high as San Jacinto Peak on my hike this afternoon.

By 1600 the precipitation finally turned to very light snow above 10,000 ft, although accumulation is less than 0.25 inch per hour.

After dark the snow level dropped to 8000 ft, with barely 0.25 inch of snow having accumulated in Long Valley (8500 ft) in two hours.

UPDATE 5th March 2025: A moderate atmospheric river storm will start to cross the San Jacinto mountains this afternoon, continuing in phases into the early hours of Friday 7th. Significant snowfall, accompanied by strong winds and severe cold, is expected in the high country, with inches of snow as low as 4000-5000 ft elevation. Further significant storms are predicted overnight on 10th-11th and again on 12th-13th March.

———————————-

This is a brief summary of trail conditions following a minor snow storm overnight on Sunday 2nd March. Although nominally the eighth storm of this winter, seven of those, like this most recent storm, have been minor and total snowfall at San Jacinto Peak since September 2024 has been a paltry 29 inches.

This summary is thankfully brief because this is expected to be the first of four storms in rapid succession – with the next three on 5th-6th, 10th-11th, and 13th-14th March – all of which are currently forecast to produce significant precipitation.

I broke trail through light snow on the morning of Monday 3rd March via Devil’s Slide Trail, a short section of the PCT, and the Wellman, Peak, and East Ridge trails, to San Jacinto Peak. At San Jacinto Peak in late morning I recorded a short video report (linked here), and also took a video of the beautifully sunny, but windy, conditions on top (linked here).

This report includes a brief dedicated Pacific Crest Trail section (below, between Weather and Trail Conditions) for the benefit of northbound PCT hikers. Additional information elsewhere in the report is however also of use to PCT hikers.

Trails below about 6600 ft are already clearing of snow, with snow on trails up to 9000 ft on the most sun-exposed slopes already becoming thin and patchy (details under Trail Conditions below).

Details of recommended traction devices are given below under Trail Conditions. In summary, carrying spikes is recommended everywhere above about 6500 ft. Crampons are potentially useful everywhere in the high country above about 9000 ft for the next couple of days as the light powder is not adhering well to the pre-existing icy snow below. Crampons are required on the north side of Tahquitz Peak (details below). Snowshoes can be useful above about 9000 ft elevation, and will become invaluable after 5th March.

For the foreseeable, hikers must be prepared for genuine winter conditions in the high country, with temperatures near or well below freezing, and potentially far below freezing when considering wind chill effects, in addition to strong winds and heavily drifting snow (see below for my recent weather observations from San Jacinto Peak).

Details of snow depths measured at a few sample locations on the trail system are given at the foot of this posting. Note however that snow depth itself is very rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across deeper snow is often much easier hiking than a poorly defined track across just a few inches depth of angled icy snow.

The USFS gate at Humber Park is open, but is expected to close on 5th March. Even when closed there are nine legal parking spaces immediately below the gate. South Ridge Road currently remains open and is readily passable, albeit somewhat lumpy in places. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is closed due to seasonal conditions.

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (even more frequently during storms), Tahquitz Peak and area 1-3 times per week, plus a wide variety of other trails on intervening days.

WEATHER

March may be far more interesting meteorologically than the preceding several months. Within hours of the passage of the light snow storm on 3rd, temperatures were already warming rapidly, with melting visible on bushes and rocks at 10,000 ft by noon that day. This will continue on Tuesday 4th.

A moderate (or even major) storm is forecast for 5th-6th March. Two precipitation phases are expected, on the afternoon and evening of Wednesday 5th, and then again on the afternoon and evening of Thursday 6th. The former will be warmer, with predominantly rain expected at mid elevations (possibly an inch in Idyllwild) before turning to snow that night. At mid elevations it may snow for much of 6th, with 3-5 inches possible.

Snow is expected throughout the higher elevations from Wednesday evening to Friday morning, with the heaviest accumulations on Wednesday and Thursday nights. Total snowfall forecasts for the high country have varied greatly from 10-25 inches, with 12-20 inches now most likely above 10,000 ft.

Temperatures may warm quickly after passage of that storm, and will be above seasonal yet again on 8th-9th, before an extended period of unstable weather is forecast starting Monday 10th March. Details remain uncertain at this time, but light or moderate precipitation is possible daily from 10th to 14th March, in the high country perhaps most likely at the beginning and end of that period.

At San Jacinto Peak (10,810ft/3295m) on Monday 3rd March 2025 at 1025 the air temperature was 11.9°F (-11°C), with a windchill temperature of -13.7°F (-25°C), 69% relative humidity, and a wild WNW wind sustained at 18 mph gusting to 30.0 mph.

At the Peak on Friday 28th February 2025 at 0800 the air temperature was 27.8°F (-2°C), with a windchill temperature of 11.3°F (-13°C), 41% relative humidity, and a bitter SE wind sustained at 17 mph gusting to 23.9 mph.

PACIFIC CREST TRAIL

The trail was largely covered in thin snow from Miles 151 (Highway 74) to about Mile 175 as of 3rd March. However this was already melting rapidly that afternoon. Some thin patchy icy snow remains on north-facing and sheltered slopes from February. A patchy 1-2 inches of snow on the north-east side of Apache Peak (Miles 169.5) poses no significant problems. Treefall hazards are a problem on parts of this section but none are insurmountable, as described in more detail below.

Snow cover is continuous from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat), with no boot track at this time through very limited consequential terrain. Many hikers may find spikes useful on this section.

PCT hikers should not attempt to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak, even though this looks temptingly simple on apps and maps. This section of steeply angled (and notoriously treacherous) ice slopes will become especially problematic after further snowfall on 5th March.

Snow cover is thin and starting to become patchy and averages 90% between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is already starting to clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is continuous. Miles 181-183 are sun-exposed and will briefly clear of snow on 4th March, and snow cover is then becomes continuous from Mile 183.5. Spikes can be useful on the snowy parts of this section, but are not required at this time for hikers experienced with snow travel.

There is currently no boot track through moderate snow cover on the PCT along Fuller Ridge (Miles 185.5-191). At this time continuing north on Fuller Ridge requires the skills and comfort level to hike on angled terrain with some moderate exposure, and spikes are recommended. After 5th March, taking the Black Mountain Road alternate will probably be recommended for the foreseeable future, pending thorough surveys.

In recent years a myth has periodically circulated on PCT social media that going up and over San Jacinto Peak somehow avoids Fuller Ridge. This is erroneous and potentially dangerous. Whether you remain on the PCT northbound (going around at lower elevation via Strawberry Junction, Mile 183) or leave the PCT at Annie’s Junction (Mile 180.8) to go up to San Jacinto Peak and then down the west side to reconnect to the PCT at about Mile 185.5, you still have to hike Fuller Ridge (Miles 185.5-190.5). It is possible to do the former route more safely by leaving the PCT at Strawberry Junction and descending Deer Springs Trail, which is largely clear of snow below Strawberry Junction, back into Idyllwild.

A well established alternate from Idyllwild – avoiding Fuller Ridge – is to connect back to the PCT at about Mile 191 using Black Mountain Road. Black Mountain Road is clear of snow for the lower five miles, and then has increasingly patchy 20% snow cover for the upper three miles to the PCT but following the road through the snow patches is obvious. Mile 192 northward to Interstate 10 is functionally clear of snow.

Although the situation improved somewhat in 2024, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed February 2025).

PCT hikers are asked to respect that overnight stays are not permitted at or near San Jacinto Peak, including in the historic shelter, to minimize impacts to a sensitive subalpine environment. Officially Mt. San Jacinto State Park permits overnight stays only in established campgrounds (Little Round Valley and Strawberry Junction are good options for thru-hikers).

Trails are covered with thin patchy snow above about 6000 ft, and light-to-moderate depth snow above about 8500 ft. Melting is rapidly underway at all elevations, and clear patches are already appearing as high as 8500 ft in places. This is expected to change dramatically from 5th March onward (see Weather above).

For details of trail conditions, including specifics of downed trees, prior to this latest minor snow storm, see the previous Report (linked here).

Everywhere above about 6500 ft carrying spikes is recommended as established trails become consolidated by hiker traffic and as they undergo freeze-thaw cycles. As always, spikes tend to be especially useful for descending, even when they are not necessarily required for ascending.

Devil’s Slide Trail has a well-traveled track through very thin snow to Saddle Junction.

There is a moderately traveled track south on the PCT from Saddle Junction (Mile 179) to about Mile 177 (Chinquapin Flat).

From Saddle Junction northbound a posthole track continues to San Jacinto Peak via Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails. Due to strong winds, the tracks may be obscure on some exposed slopes.

There is now a continuous posthole track on the Peak Trail. However the track turns up to the Peak near Miller Peak via the East Ridge Trail route. These tracks may well have been obscured by spindrift snow by the afternoon of 3rd March.

Tahquitz Peak trail from Chinquapin Flat/PCT Mile 177 has a challenging and very lightly traveled posthole track to follow through the steeply angled icy snow. These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for most hikers at this time. Spikes (or preferably crampons) are strongly recommended, with at least hiking poles or ideally an ice axe (and, critically, adequate knowledge of how to use it).

SNOW DEPTHS

Measured on 3rd March 2025. The first number gives total average depth. Due to strong winds accompanying the most recent storm system there was extensive drifting and accumulation in the trails. The number in parentheses indicates the new snowfall in the storm on 2nd-3rd March. Altitudes and PCT Miles are approximate.

San Jacinto Peak (10810 ft): 10 inches (4 inches new snow on 3rd March)

Wellman Divide (9700 ft): 6 inches (3 inches new snow on 3rd March)

Annie’s Junction/approx. PCT Mile 180.8 (9020 ft): 12 inches (3 inches new snow on 3rd March)

Saddle Junction/approx. PCT Mile 179 (8070 ft): 2-3 inches (2 inches new snow on 3rd March)

Devil’s Slide Trail at Humber Park (6550 ft): 0-1 inches (1 inch new snow on 3rd March, already largely melted by that afternoon)

Idyllwild (at 5550 ft): 0 inches (0.5 inch new snow on 3rd March, already largely melted)

UPDATE Friday 28th February 2025: I recorded a video report from San Jacinto Peak early this morning (linked here), giving a feel for current conditions and discussing the significant weather change on the way. Below seasonal temperatures are expected for the next two weeks, with three snow storms in quick succession expected on 2nd-3rd, 5th-6th, and 10th-11th March. Even limited snowfall in the first of these storms will be enough to complicate conditions underfoot in the high country by obscuring the thin icy snow above about 9000 ft elevation (lower in places) that persists from mid February.

Despite the moderate storm mid month, Southern California continues to experience one of the the driest winters since records began in 1850. Worse still, this is easily the driest winter in history for the San Jacinto mountains high country, where total snowfall at San Jacinto Peak since September 2024 has been a paltry 25 inches. That number will need to more than double in the next couple of months even to match the lowest snow total in recorded history (57.75 inches in winter 2021/22). The air temperature at San Jacinto Peak on Monday 24th (40.8°F/5°C) was the hottest ever recorded there in the month of February.

The first – and so far only – notable storm of this winter, between Wednesday 12th and Friday 14th February, accounted for 70% of this winter’s snowfall to date and was described in detail in the previous report (linked here). There is an increasing possibility of a minor storm on 2nd-3rd March, with 1-5 inches of snow forecast for the high country, and a mix of light snow and rain for mid elevations.

This report is the first of the season to include a dedicated Pacific Crest Trail section (below, between Weather and Trail Conditions) for the benefit of northbound PCT hikers. Additional information elsewhere in the report is however also of use to PCT hikers.

Trails below about 7600 ft are now generally clear of snow, with snow on trails up to 9000 ft on sun-exposed slopes becoming increasingly patchy (details under Trail Conditions below).

Carrying spikes is recommended throughout the trail system above about 7500 ft. While they are not required, depending upon your expertise and comfort level hiking on shallow, variable, icy snow – with snow condition itself depending on time of day and sun exposure – spikes continue to be widely useful as established tracks undergo freeze-thaw cycles and are consolidated by hiker traffic. Typically spikes tend to be much more valuable for descending trails than for ascending.

Snowshoes are no longer helpful on the established trail system, which is too compacted for their use. Hikers venturing well off-trail may find that they remain valuable in some areas above about 9000 ft.

Hikers should be prepared for temperatures near or below freezing in the high country, and well below freezing when considering wind chill effects, from 28th February into the first week of March (see below for my recent weather observations from San Jacinto Peak).

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

Details of snow depths measured at various locations on the trail system are given at the foot of this posting. Note however that snow depth itself is very rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across deeper snow is often much easier hiking than a poorly defined track across just a few inches depth of angled icy snow.

The USFS gate at Humber Park reopened on 18th February after a brief closure. Even when closed there are nine legal parking spaces immediately below the gate. South Ridge Road remains open and is readily passable, albeit somewhat lumpy in places. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is closed due to seasonal conditions.

WEATHER

Since the passage of the storm more than a week ago, temperatures have been largely above seasonal. Temperatures are forecast to be far above average for February from 23rd-27th, with snow softening and melting everywhere.

A rapid cooling will result in temperatures below average from 28th February throughout the first week of March, as minor systems pass through on 2nd-3rd and again 5th-6th March. From 27th February onwards, most days will be partly or mostly cloudy.

Forecasts are currently indicating possibilities for light precipitation on 1st-6th March, most likely on 3rd, with 1-3 inches of snow possible at the highest elevations. The system will be cold enough to produce a dusting of snow as low as 4000 ft.

At San Jacinto Peak (10,810ft/3295m) on Friday 28th February 2025 at 0800 the air temperature was 27.8°F (-2°C), with a windchill temperature of 11.3°F (-13°C), 41% relative humidity, and a bitter SE wind sustained at 17 mph gusting to 23.9 mph.

At the Peak on Monday 24th February 2025 at 0810 the air temperature was 40.8°F (5°C), with a windchill temperature of 30.6°F (-1°C), 55% relative humidity, and a very light NW wind sustained at 3 mph gusting to 7.5 mph.

At the Peak on Thursday 20th February 2025 at 0820 the air temperature was 35.6°F (2°C), with a windchill temperature of 23.2°F (-5°C), 17% relative humidity, and a steady NNW wind sustained at 10 mph gusting to 18.3 mph.

PACIFIC CREST TRAIL

The trail is largely clear of snow from Miles 151 (Highway 74) to about Mile 175. Some thin patchy snow remains on north-facing and sheltered slopes. A patchy 1-2 inches of snow on the north-east side of Apache Peak (Miles 169.5) poses no significant problems. Treefall hazards are a problem on parts of this section but none are insurmountable, as described in more detail under Trail Conditions.

Snow cover is continuous from Miles 175 (Red Tahquitz) to 177.7 (Chinquapin Flat), with a lightly-traveled boot track through very limited consequential terrain. Many hikers may find spikes useful on this section.

PCT hikers attempting to use South Ridge Trail from the PCT at Chinquapin Flat (roughly Mile 177.7) to Idyllwild via Tahquitz Peak – even though this looks temptingly simple on apps and maps – should note that there is only a rough track with limited steps to follow through a section of steeply angled (and notoriously treacherous) ice slopes.

Snow cover is thin and starting to become patchy and averages 90% between Miles 177.7 to Saddle Junction (about Mile 179). The south-facing slope of Miles 179-180 is 50% clear, but from Mile 180 (elevation 8900 ft) to about Mile 181 just past Annie’s Junction snow cover is continuous. Miles 181-183 are sun-exposed and clearing of snow, and snow cover then becomes largely continuous from Mile 183.5. Spikes can be useful on the snowy parts of this section, but are not required at this time for hikers experienced with snow travel.

There is a boot track through an average of 90% moderate snow cover on the PCT along Fuller Ridge (Miles 185.5-191), steadily clearing on the most sun-exposed areas. The track does not accurately follow the PCT route in some places and passes through some challenging terrain, especially in Miles 185.5-187. At this time continuing north on Fuller Ridge requires the skills and comfort level to hike on angled terrain with some moderate exposure, and spikes are recommended.

In recent years a myth has periodically circulated on PCT social media that going up and over San Jacinto Peak somehow avoids Fuller Ridge. This is erroneous and potentially dangerous. Whether you remain on the PCT northbound (going around at lower elevation via Strawberry Junction, Mile 183) or leave the PCT at Annie’s Junction (Mile 180.8) to go up to San Jacinto Peak and then down the west side to reconnect to the PCT at about Mile 185.5, you still have to hike Fuller Ridge (Miles 185.5-190.5). It is possible to do the former route more safely by leaving the PCT at Strawberry Junction and descending Deer Springs Trail, which is largely clear of snow below Strawberry Junction, back into Idyllwild.

A well established alternate from Idyllwild – avoiding Fuller Ridge – is to connect back to the PCT at about Mile 191 using Black Mountain Road. Black Mountain Road is clear of snow for the lower five miles, and then has increasingly patchy 20% snow cover for the upper three miles to the PCT but following the road through the snow patches is obvious. Mile 192 northward to Interstate 10 is functionally clear of snow.

PCT hikers are asked to respect that overnight stays are not permitted at or near San Jacinto Peak, including in the historic shelter, to minimize impacts to a sensitive subalpine environment. Officially Mt. San Jacinto State Park permits overnight stays only in established campgrounds (Little Round Valley and Strawberry Junction are good options for thru-hikers).

TRAIL CONDITIONS

Trails are covered with thin patchy snow above about 7500 ft, and light-to-moderate depth snow above about 8500 ft. Melting is steadily underway at all elevations, and clear patches are already appearing as high as 9000 ft in places. Due to unusually mild temperatures at all elevations this week, snow is softening as early as mid morning, and significant postholing is possible by late morning.

Everywhere above about 7500 ft carrying spikes is recommended as established trails become consolidated by hiker traffic and as they undergo freeze-thaw cycles. This elevation will continue to rise over the next few days as sun-exposed trails continue to melt. As always, spikes tend to be especially useful for descending, even when they are not necessarily required for ascending. For example I have yet to need spikes to ascend to San Jacinto Peak since recent snowfall, but have used them to descend down to 8900 ft on Deer Springs Trail.

Devil’s Slide Trail is now clear of snow to about 7600 ft. From there to Saddle Junction there is about 40% cover of thin and increasingly patchy icy snow to Saddle Junction. Some hikers will find spikes useful in this upper section, especially for descending.

There is a moderately traveled posthole track south on the PCT from Saddle Junction (Mile 179) to about Mile 177 (Chinquapin Flat), that is then very lightly-traveled onward to Tahquitz Peak.

From Saddle Junction northbound a well-traveled track continues to San Jacinto Peak via Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails.

There is now a continuous posthole track on the Peak Trail. However the most-consolidated posthole tracks turn up to the Peak near Miller Peak via the East Ridge Trail route, and although there are various meandering options ascending the ridge, they all merge near the Peak.

Also on the tram side, there is a well-traveled posthole track from Long Valley through Round Valley to Wellman Divide. Earlier tracks coming directly up from the tram via Tamarack Valley (the “Sid Davis” route) that were put in immediately after the storm last week are no longer passable due to melting.

Deer Springs Trail is clear of snow to the Suicide Rock trail junction. The trail remains clear of snow to 7500 ft, with then about 10% thin snow cover nearer Strawberry Junction (8050 ft). Thereafter snow cover is largely continuous to San Jacinto Peak, albeit thin and starting to become patchy especially below 8600 ft. The track is relatively lightly-traveled but easy to follow to the junction with Marion Mountain Trail. Above that point the well-traveled track largely follows the true trail route to Little Round Valley. Above Little Round Valley, there is a mess of meandering posthole tracks that all head upslope toward San Jacinto Peak, with none of them consistently or accurately following the trail route (as is typical in winter with adequate snow depth on this slope), before coalescing near Summit Junction (10,500 ft).

On the section of Deer Springs Trail between Strawberry Junction and the top of Marion Mountain Trail (roughly PCT Miles 183-185) six significant treefall hazards remain, mostly from high winds in January. Three more came down in a concentrated area just north of the top of Seven Pines Trail (near Mile 185.2). About ten further trees on the upper trail (above Fuller Ridge) have been down and reported repeatedly for more than a decade but with no action from the State Park. Two significant obstructions are down across the trail between the Suicide Rock Trail junction and Strawberry Junction.

Marion Mountain Trail is clear of snow to 7600 ft. For a brief transition 0.1 mile above that elevation, icy snow cover is about 50%, before quickly becoming 90% up to the PCT/Deer Springs Trail. There is a good boot track to follow throughout. While spikes are not essential on the ascent, most hikers will find them invaluable for the descent. Several large tree limbs and four medium-sized trees came down across the trail in recent weeks, with one on the Forest Service section and three in the State Park, all of which are relatively easy to pass over for hikers.

South Ridge Trail [updated 28th] is now largely clear of snow until the uppermost switchbacks close to the peak. In the uppermost switchbacks (>8500 ft, switchback 12) icy snow cover averages 60%, and some hikers will find spikes useful, especially for descending. Five treefall hazards that came down in the trail earlier this year have already been removed by the Trail Report, and the most extensive trail trimming program on South Ridge in more than a decade has continued throughout this winter.

Tahquitz Peak trail from Chinquapin Flat/PCT Mile 177 has a challenging and very lightly traveled posthole track to follow through the steeply angled icy snow (photo in previous Report linked here). These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for most hikers at this time. Spikes (or even crampons) are strongly recommended, with at least hiking poles or preferably an ice axe (assuming adequate knowledge of how to use it).

Although the situation has improved somewhat in recent months, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed January 2025).

On the Fuller Ridge Trail section of the PCT there are 12 trees down on the State Park section of the trail (Miles 185.5-189, which have not been maintained by that agency for many years). Several of these pose quite significant hazards for hikers. On the Forest Service section (Miles 189.3-190.5) five significant treefall hazards were removed by USFS late in 2024. Snow cover on Fuller Ridge Trail averages only 50%, but is very localized with sun-exposed sections completely clear and shaded sections still with 1-2 inches depth of snow in the trail.

Trees down on the Strawberry Trail section of the PCT (Annie’s Junction to Strawberry Junction, Miles 180.8-183) have remained uncut by the Forest Service for nearly a decade. About six hazards on this section are thankfully all relatively easy for hikers to negotiate.

The Trail Report heavily trimmed the formerly overgrown Wellman Trail (Annie’s Junction to Wellman Divide) from September 2024-January 2025.

In February 2025 the Trail Report cleared Spitler Peak Trail of the six trees that came down in Santa Ana winds in January (bringing to 129 the total number of trees removed by the Report from this trail in recent years). We also removed most of the whitethorn from the central portion of the trail in December 2024. While more brush trimming work is always required, in general the trail is currently in its best condition since at least mid 2023. Spitler Creek continues to flow gently at its various crossings in the upper switchbacks, and Antsell Rock Creek starting flowing gently again late last year.

The Trail Report removed the only two new small trees down across Fobes Trail earlier in February. The trail is otherwise largely clear, with only a few minor branch hazards mainly along the lower trail.

The Caramba Trail from near Reeds Meadow through Laws Camp and on to Caramba, and the Cedar Trail from Willow Creek Trail to Laws, are euphemistically (and potentially dangerously) described by the Forest Service as “not maintained”. In reality both trails have been abandoned and no longer exist. They are so heavily overgrown, largely with dense whitethorn, which obscures dozens of downed trees, that hikers should not attempt to follow them (regardless of how much you may trust an app). An informal use trail to Laws is much more direct, well maintained, and avoids the bushwhacking of the unmaintained trails (some local Idyllwild hikers dubbed it the “King Trail” when I established the route in 2019). It leaves Willow Creek Trail exactly 1.0 mile from Saddle Junction, 0.46 mile from the Skunk Cabbage turning (trailhead at N 33.7796, W 116.6590). The route descends largely following established deer trails for 1.2 miles, meeting Willow Creek about 0.2 mile upstream from the site of the historic Laws Camp (the remains of which were destroyed by the 2013 Mountain Fire and subsequent flood and treefall damage). One huge tree fell in late 2024 across the King Trail about midway down and requires a minor scramble underneath (that tree will not be cut soon), while another fell in January 2025 close to the bottom of the trail that is relatively easy to cross over. Another five recently downed trees were either removed or worked around in January 2025, when the trail was thoroughly trimmed and cleared. From Laws east to Caramba the route of the original Caramba Trail has been cairned by myself and others and can largely be followed with careful route-finding. My February 2025 survey counted about 120 trees down on this 2.1 miles of trail. It is extremely obscure for the first 0.5 mile east of the Willow Creek crossing, becoming more obvious (but still subtle) as it descends towards Caramba. Very cautious navigation is advised throughout the area.

In late 2024 Willow Creek Trail was nearing its 2020 condition, the last time the original trail route was fully cleared and passable. Four new trees came down on the Forest Service section in January, two of which are large and tricky for hikers to pass. In addition to trees being cut in 2024, whitethorn trimming was largely completed, mainly by volunteers, on the Forest Service side in late summer. On the State Park side localized trimming of the worst patches was undertaken in 2024, and the minor treefall hazards new in 2023/24 were removed, leaving just two major long term downed trees (both easy to pass for hikers).

The Trail Report “adopted” Seven Pines Trail as a priority for maintenance work as the trail had a disproportionate number of lost hiker rescues in the past decade, and both State Park and Forest Service have shown no interest in maintaining the route for years. Since 2020 we have removed 75 downed trees and the trail is trimmed and cleared multiple times annually. As of late 2024 the trail is – by its low standards – relatively clear of treefall hazards, with three down across the trail in its upper section, all easily passable for hikers. A further half-a-dozen downed trees close to the PCT junction would need to be removed to fully restore the original route of the trail. Although the condition of the trail is greatly improved, Seven Pines remains a genuine wilderness trail unlike the wider, bare, obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains essential for those without considerable experience of hiking this trail. Be aware in particular that Seven Pines Trail becomes most obscure in the mile closest to its junction with Deer Springs Trail/PCT.

The Zen Center Trail continues its serious deterioration that started following the 2013 Mountain Fire, with a combination of vigorous regrowth and treefall hazards further obscuring the route with each passing season. The lower and upper thirds of this trail are partially cairned and not too bad for those who are very familiar with the former route, but even the experienced find navigating the central section tricky. Long trousers, scrambling gloves, and an enjoyment of bush-whacking are all strongly recommended.

SNOW DEPTHS

Measured on 24th February 2025 (20th February for Deer Springs Trail locations). Note that average depth is given; due to strong winds accompanying the storm system there was extensive drifting, especially in the trails. Altitudes and PCT Miles are approximate. Also note that – remarkably for February – none of these locations had any snow remaining from prior storms (i.e. everything recorded here was from the latest, mid February, storm).

San Jacinto Peak (10810 ft): 11 inches (was 17.5 inches on 14th February, drifted areas ranging from 7-24 inches)

Little Round Valley (9750 ft): 16 inches (drifted to 24 inches in places)

Wellman Divide (9700 ft): 6 inches (was 17 inches on 14th February, heavily drifted in places)

Annie’s Junction/approx. PCT Mile 180.8 (9020 ft): 13 inches (was 16-17 inches on 14th February)

Fuller Ridge Trail junction with Deer Springs Trail/approx. PCT Mile 185.5 (8800 ft): 12 inches

Saddle Junction/approx. PCT Mile 179 (8070 ft): 1-2 inches (was 3.5 inches on 14th February)

Strawberry Junction/approx. PCT Mile 183.1 (8050 ft): 1-2 inches (patchy 0-4 inches)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inches (was 2-3 inches on 14th February)

Idyllwild (at 5550 ft): 0 inches (0.25 inch of snow on 12th February, and 5.3 inches of rain 12th-14th February)

UPDATED Thursday 20th February: I hiked to San Jacinto Peak today for the fourth time in the past week, ascending via the Wellman and Peak trails, descending Deer Springs Trail, and have updated the Trail Conditions section below accordingly. I summarized my observations from Sunday 16th in a video report from the far-too-warm-for-February Peak (linked here). On 17th we hiked both north and south sides of Tahquitz Peak. High country tracks are generally firm and reliable underfoot in the early morning, but become soft by late morning, with a much greater likelihood of postholing by and after noon.

————————————-

This is a summary of conditions following the seventh, but by far most substantial, snow storm of winter 2024/25, with the majority of the snow falling between the afternoon of Thursday 13th and the morning of Friday 14th February.

Exactly six years on from the (in)famous Valentine’s Day flood of 2019 – when eight inches of rain in less than a day destroyed several mountain roads, some for months – heavy rain was also a feature of this storm, with Idyllwild recording 5.3 inches (and nearly four inches in one 24 hour period).

This complex storm sequence had multiple phases as discussed under Weather below. The practical consequence was a strikingly high snow level, with moderate snow above about 8500 ft, and surprisingly shallow snow lower down. I have never recorded such a discrepancy in snow depths between Saddle Junction (8100 ft, with just three inches by the afternoon of 14th) and Annie’s Junction (9020 ft, nearly 18 inches).

Final storm totals included 17-18 inches at San Jacinto Peak, similar amounts at Wellman Divide and Annie’s Junction (due to the complexities of the timing of the snowfall), just 10-11 inches at Long Valley, and three inches or fewer from Saddle Junction (8100 ft) down to about 6500 ft.

I recorded a short video report from San Jacinto Peak in the snow just after 0900 on Friday 14th (linked here).

Most trails have now been traveled and most are no longer obscured by significant snowfall, due to hiker traffic and with rapid melting continuing. Nevertheless cautious navigation is recommended everywhere. Snow depths measured on 14th are listed at the foot of this posting, but note that due to very strong winds accompanying the storm there was extreme drifting, and snow is often deeper in the trails.

Until about 18th, conditions were unusually good for snowshoeing above about 9000 ft on most of the mountain, and as low as 8000 ft on the eastern side (where less impacted by rainfall). Rarely have I encountered such a densely formed snowpack in fresh powder, and I was gliding across the surface of the snow on 14th. With compaction from freeze/thaw cycles, conditions are now better for spikes.

Everywhere above about 7000 ft it is recommended to carry spikes for the foreseeable future as established trails have become consolidated by hiker traffic and as they undergo freeze-thaw cycles. This elevation will rise further over the next week as sun-exposed trails rapidly melt.

Sadly – but unsurprisingly given the trend this winter – temperatures abruptly rise to above seasonal on Saturday 15th February, and remain warm for days, possibly even for the remainder of the month. Consequently melting will be rapid at all elevations, especially on sun-exposed slopes. Only those traditional locations that are especially sheltered – for example the north face of Tahquitz Peak, either side of Annie’s Junction (PCT Mile 180.8), in and below Little Round Valley – may continue to hold deep snow for the next several weeks.

The USFS gate at Humber Park reopened on 18th February after a brief closure. Even when closed there are nine legal parking spaces immediately below the gate. If there is a “Road Closed” sign lower down, it is also possible to park along Forest Drive. South Ridge Road remains open and is readily passable, albeit somewhat lumpy in places. Dark Canyon Road (4S02), the access road to the Seven Pines trailhead, is closed due to seasonal conditions.

WEATHER

Temperatures are forecast to abruptly rise above seasonal averages this weekend and remain elevated for the remainder of February, especially on 23rd-27th. By Sunday 23rd record high temperatures for the month of February are possible around the highest peaks. Most days are forecast to be clear and sunny until the turn of the month. Obviously these factors will combine to cause rapid snow melt and deteriorate hiking conditions markedly.

The three day storm on 12th-14th was complex with three distinct phases. The first cold phase on the morning of Wednesday 12th included snow dusting down to just below 5000 ft but minimal depth, with only 0.25 inch in Idyllwild and 0.5 inch at Tahquitz Peak (8836 ft). Upper elevations and especially the eastern side of the mountains received no measurable snow at that time.

As temperatures warmed on 12th and into 13th, the shallow snow at mid elevations melted, producing slush on the trails below 9000 ft. Rainfall then dominated as the snow level rose – briefly as high as San Jacinto Peak – before stabilizing around 8500 ft.

From the evening of 12th to the early hours of 14th, rainfall dominated below about 8500 ft, with snowfall above that elevation, and the greatest intensity of both overnight on 13th.

The final third phase was another cooling as the system departed, with the snow level dropping to 6000 ft early on 14th. Precipitation became more inconsistent throughout 14th, finally ending in the early afternoon.

At San Jacinto Peak (10,810ft/3295m) on Thursday 20th February 2025 at 0820 the air temperature was 35.6°F (2°C), with a windchill temperature of 23.2°F (-5°C), 17% relative humidity, and a steady NNW wind sustained at 10 mph gusting to 18.3 mph.

At the Peak on Sunday 16th February 2025 at 0915 the air temperature was 36.4°F (2°C), with a windchill temperature of 30.1°F (-1°C), 45% relative humidity, and a very light WNW wind sustained at 3 mph gusting to 5.8 mph.

At the Peak on Friday 14th February 2025 at 0915 the air temperature was 20.4°F (-6°C), with a windchill temperature of -1.3°F (-19°C), 100% relative humidity, and a bitter WNW wind sustained at 17 mph gusting to 26.7 mph.

TRAIL CONDITIONS

Trails are snow-covered with thin snow above about 7500 ft, and moderate depth snow above about 8500 ft. Melting is underway at all elevations, and clear sections are already appearing below 7500 ft, e.g., lower Devil’s Slide Trail, South Ridge Trail, and lower Deer Springs Trail.

Until about 18th least, beware of large volumes of ice falling from trees over trails, especially from 8000-10,000 ft. Although this happens to some extent following every storm, due to the large volume and high elevation of freezing rain associated with this latest storm, the ice fall risk is unusually noteworthy at present.

Everywhere above about 7500 ft carrying spikes is strongly recommended for the foreseeable future [updated 20th February] as established trails become consolidated by hiker traffic and as they undergo freeze-thaw cycles. This elevation will rise over the next few days as sun-exposed trails continue to melt. As always, spikes tend to be especially useful for descending, even when they are not necessarily required for ascending. Early on the morning of 20th I did not need spikes at all to ascend the Wellman and Peak trails to San Jacinto Peak, on an excellent firm snow track, but used them to descend down to 8900 ft on Deer Springs Trail. By about 1030, snow was becoming soft below Strawberry Junction (but was thankfully already very shallow).

Conditions remain suitable for snowshoeing above about 9000 ft on most of the mountain. Snowshoes may actually become increasingly useful over the next week to minimize postholing as snow softens by late morning, especially on sun-exposed slopes.

Devil’s Slide Trail [20th February] is now functionally clear of snow to about 7500 ft. Hikers are unlikely to require spikes below that elevation. From there to Saddle Junction there is a well-consolidated track to follow through thin, icy snow to Saddle Junction. Spikes are useful in this upper section, especially for descending.

There is a lightly traveled posthole track south on the PCT from Saddle Junction (Mile 179) to about Mile 177 (Chinquapin Flat).

From Saddle Junction northbound [20th February] a well-traveled track continues to San Jacinto Peak via Annie’s Junction (PCT Mile 180.8) and Wellman Divide, via the Wellman, Peak, and East Ridge trails.

Tracks on the Peak Trail end near Miller Peak, where they are joined by tracks coming up from the tram via Tamarack Valley. These all continue up to the Peak via the East Ridge Trail route [20th February], and although there are various options ascending the ridge, they all end up at the Peak.

Also on the tram side, there is a well-traveled posthole track from Long Valley through Round Valley to Wellman Divide.

Deer Springs Trail [20th February] is clear of snow to the Suicide Rock trail junction. The trail remains largely clear of snow to 7500 ft, with then about 50% thin snow cover to Strawberry Junction. Thereafter snow cover is continuous to San Jacinto Peak, albeit very thin below 8600 ft. The track is relatively lightly-traveled but easy to follow to the junction with Marion Mountain Trail. Above that point the well-traveled track is relatively easy to follow, and largely follows the true trail route, to Little Round Valley. Above Little Round Valley, there is only a scattering of posthole tracks that all meander upslope to San Jacinto Peak, with none of them approximating to the trail route (as is traditional in with adequate snow depth on this slope).

South Ridge Trail [22nd February] has a posthole track to Tahquitz Peak fire lookout. The trail is clear of snow to Old Lookout Flat (at 7600 ft). Snow cover averages 50% beyond that. In the uppermost switchbacks (>8500 ft, switchback 12) snow cover is continuous, uneven (due to icefall) and most hikers will find spikes are useful, especially for descending.

Tahquitz Peak trail from Chinquapin Flat/PCT Mile 177 has a challenging and very lightly traveled posthole track to follow through the steeply angled icy snow (photo below). These slopes comprise some of the most consequential terrain in winter in these mountains, and this route is not recommended for most hikers at this time. Spikes (or even crampons) are strongly recommended, with at least hiking poles or preferably an ice axe (assuming adequate knowledge of how to use it).

SNOW DEPTHS

Measured on 14th February 2025. Note that average depth is given; due to strong winds accompanying the storm system there is extensive drifting, especially in the trails. Altitudes and PCT Miles are approximate. Also note that – remarkably for February – none of these locations had any snow remaining from prior storms (i.e. everything recorded here was from this latest storm).

San Jacinto Peak (10810 ft): 18 inches (drifted areas ranging from 7-24 inches)

Wellman Divide (9700 ft): 17 inches, heavily drifted in places.

Annie’s Junction/approx. PCT Mile 180.8 (9020 ft): 15-18 inches

Saddle Junction/approx. PCT Mile 179 (8070 ft): 3 inches

Devil’s Slide Trail at Humber Park (6550 ft): 2 inches (largely slushy, melting already underway)

Idyllwild (at 5550 ft): 0 inches of snow. The 0.25 inch on 12th melted very rapidly. An impressive 4.69 inches of rain since the 12th included 3.72 inches in the 24 hour period starting 0700 on 13th.

Only the seventh storm of winter 2024/25 – but by far the most notable one for expected precipitation – is forecast to move across the San Jacinto mountains between Wednesday 12th and Friday 14th February 2025.

Please check this page for periodic updates – the most recent is at the top – throughout the multiple day storm sequence. The next comprehensive Report update, summarizing conditions during and after the storm, may be published late on Friday 14th February.

UPDATE Friday 14th February at 1010: it continues to snow gently in the high country, but it is accumulating at only 0.25-0.5 inch per hour. Storm total at San Jacinto Peak is 16-17 inches.

I recorded a short video report from San Jacinto Peak in the snow just after 0900 (linked here).

UPDATE Friday 14th February at 0700: Idyllwild has recorded an impressive 3.72 inches of rain in the past 24 hours, for a current storm total of 4.69 inches.

Snow depths broadly doubled overnight, with storm totals of 14-16 inches at San Jacinto Peak and 9-10 inches in Long Valley (8500 ft). Strong winds overnight mean that drifting is severe, with measurements around San Jacinto Peak ranging from 7-22 inches. Snow fell entirely as fine rounded grains (rather than big flakes) so couldn’t reach the most optimistic depths forecast.

UPDATE Thursday 13th February at 1700: Snow has been slow to accumulate at San Jacinto Peak, with currently 5.0 inches of fresh powder (but very heavily drifted in strong winds).

Snow level on my morning hike was above 9000 ft, with rain below 8500 ft, and sleet in between, but all are expected to drop overnight.

Idyllwild has added 1.32 inches of rain since 0700 today, for a storm total of 2.29 inches already (and the most intense precipitation still to come in the next few hours).

UPDATE Thursday 13th February at 1330: Freezing rain overnight reached all the way to San Jacinto Peak before turning to light snow early this morning. There is currently 3.5 inches of fresh powder at the Peak, and I measured 2.5 inches at Wellman Divide (9700 ft) a couple of hours earlier. The heavy snowfall is expected over the next 12 hours.

Idyllwild has added another 0.75 inches of rain since 0700 for a storm total of >1.7 inches so far. Trail conditions were challenging between 7500-9300 ft, with heavy water flows running underneath 1-2 inches of slush as the light snow from yesterday melted.

UPDATE Thursday 13th February at 0700

Rainfall in the past 24 hours in Idyllwild has totaled 0.97 inch and is steadily intensifying. It finally started snowing lightly in Long Valley at about 0500 this morning, accumulating very slowly.

UPDATE Wednesday 12th February at 1950

Very light misty drizzle in Idyllwild for most of the afternoon and evening has added up to 0.15 inch so far. This aligns with most weather stations in the San Jacinto mountains which are reporting 0.1-0.2 inch, with 0.25 inch in Anza. The eastern slope is still not reporting any snow at upper elevations.

UPDATE Wednesday 12th February at 1340

We hiked to a windy and frigid Tahquitz Peak (8836 ft) this morning through very light, fine snow, and recorded a short video report from the fire lookout (linked here). Periodic brighter spells suggested that the top of the cloud was just above us, somewhere between 9000-10,000 ft, and hence unsurprisingly Long Valley (at 8500 ft on the east slope) remains snow-free at this time. No more than 0.5 inch accumulated around Tahquitz Peak, and by the time we descended, snow was starting to melt as high as 8500 ft and below 6500 ft it had already completely melted as the temperature rose to a few degrees above freezing.

UPDATE Wednesday 12th February at 0630

In the early hours of this morning Idyllwild was dusted with 0.25 inch of snow, but it had stopped by first light. The high country and eastern side of the mountains have remained largely above the cloud at this time, with no snow in Long Valley (8500 ft). As the bulk of the storm system moves in, temperatures are forecast to rise, with rain starting at mid elevations around noon and light snow in the high country around dusk. Total snow accumulation estimates for the high country have increased, with up to two feet now possible on Thursday.

UPDATE Wednesday 12th February 2025 at 0630: In the early hours of this morning Idyllwild was dusted with 0.25 inch of snow, but it had stopped by first light. The high country and eastern side of the mountains have remained largely above the cloud at this time, with no snow in Long Valley (8500 ft). As the bulk of the storm system moves in, temperatures are forecast to rise, with rain starting at mid elevations around noon and light snow in the high country around dusk. Total snow accumulation estimates for the high country have increased, with up to two feet now possible on Thursday.

————————————-

The first substantial storm system of winter 2024/25 to impact Southern California is finally forecast for this coming week. A moderate “atmospheric river” is expected between Wednesday 12th and Friday 14th February, with the first light precipitation possible on the evening of Tuesday 11th. The system will be mild, with a high snow level that may drop close to 5000 ft only briefly at the beginning and end of the storm sequence. Consequently rain is forecast for mid elevations (e.g., Idyllwild), with an impressive 2-4 inches possible. Snow estimates for the highest elevations of the high country have ranged widely from 10-40 inches, although a depth around 12-18 inches is now most likely. Regardless of the final depth, impacts on the trail system could be significant, at least for the remainder of February.

Melting of the light snow from the storm on 26th-27th January has been rapid. We experienced continuous snow cover in the high country for only four days (the late January storm is described in detail in a prior Report linked here). Total snowfall at San Jacinto Peak since September 2024 has been a pitiful 7.6 inches. Most trails are clear of snow (details under Trail Conditions below).

In the early hours of Friday 7th February we caught the southernmost edge of an atmospheric river passing to the north. I hiked to San Jacinto Peak that morning through pleasant misty cloud and periodic drizzle before reaching patchy blue sky right around the Peak. The storm was mild, producing only rain all the way to the highest elevations. Above 9500 ft freezing rain plastered all surfaces with ice but that quickly melted in full sun the following day. Saddle Junction (8100 ft) with 0.51 inch recorded the most rainfall, with 0.41 inch at Wellman’s Cienega (9300 ft), 0.32 inch in Idyllwild, and 0.2 inch at San Jacinto Peak.

Conditions are currently suitable for spikes in places above about 8700 ft on the western slope (e.g., Deer Springs Trail) as the established trails have undergone freeze-thaw cycles and remaining thin snow has become icy due to consolidation by hiker traffic. Recommendations for traction devices are expected to change significantly starting 12th February.

Hikers must be prepared for temperatures below freezing in the high country, and well below freezing when considering wind chill effects, for the foreseeable future (see below for my recent weather observations from San Jacinto Peak).

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days.

Regardless of how low the snow level drops during the storm this week, access to Forest Service dirt roads may well close due to seasonal conditions, at least temporarily. The USFS gate at Humber Park is currently open. Even when closed there are nine legal parking spaces immediately below the gate. South Ridge Road is currently open and is readily passable with AWD/4WD vehicles.

WEATHER

Following temperatures this past weekend that were again well above seasonal, a rapid cooling will result in temperatures below average on 11th-14th February.

As described above, a moderate storm system is forecast for this coming week, impacting the San Jacinto mountains between Tuesday 11th and Friday 14th February. The system will be relatively mild with several inches of rain forecast for mid elevations, with a possibility for light snow at the beginning of the storm as low as 5000 ft (which will subsequently melt as temperatures rise on 13th and 14th).

Snow estimates for the high country have ranged as high as 40 inches. The most likely final depth is now expected to be 1-2 feet at most. The relative warmth of the system will result in a high snow level, around 7000-8000 ft for much of the storm, with consequently little or no snowfall expected below 6000 ft.

Immediately after passage of the storm, temperatures quickly rise to above seasonal at all elevations starting 15th February, but most strikingly at the highest elevations. Consequently melting of snow may be rapid once again.

At San Jacinto Peak (10,810ft/3295m) on Monday 10th February 2025 at 0845 the air temperature was 24.9°F (-4°C), with a windchill temperature of 8.2°F (-13°C), 44% relative humidity, and a cool due West wind sustained at 13 mph gusting to 18..7 mph.

At the Peak on Sunday 9th February 2025 at 0835 the air temperature was 29.4°F (-1°C), with a windchill temperature of 14.5°F (-10°C), 12% relative humidity, and a steady WSW wind sustained at 14 mph gusting to 18.9 mph.

At the Peak on Friday 7th February 2025 at 0940 the air temperature was 27.4°F (-3°C), with a windchill temperature of 8.8°F (-13°C), 100% relative humidity, and a bitter WSW wind sustained at 18 mph gusting to 28.4 mph.

TRAIL CONDITIONS

There is currently no continuous settled snow in the San Jacinto mountains, an unprecedented situation in recorded history this late into the winter. The thin covering above 9000 ft that fell on 7th January only lasted for a few days despite cold temperatures, while the 4-6 inches of snow from the minor storm on 26th-27th January has already largely melted. Obviously this situation is expected to change starting Wednesday 12th February, and hikers must be fully prepared for winter conditions thereafter.

Most hikers will find that traction devices are not widely required on the trail system at this time, although conditions are currently suitable for spikes in places above about 8700 ft on the western slope (Deer Springs Trail and short parts of the PCT) as the established trails have undergone freeze-thaw cycles and the thin snow has become icy due to consolidation by hiker traffic. Spikes tend to be much more valuable for descending trails than ascending.

There is functionally no snow on trails on the eastern side trails, e.g., the Peak Trail is almost completely clear. Tiny patches persist in the most sheltered areas above 9000 ft, notably either side of Annie’s Junction (PCT Mile 180.8), then again at 9900-10,100 ft on the Peak Trail and above 10,500 ft around San Jacinto Peak.

The East Ridge Trail (between Miller-San Jacinto peaks) is still 50% snow-covered, but only one inch deep and with a well-traveled (but icy) track accurately following the old trail route.

Deer Springs Trail is clear of snow from the trailhead to Strawberry Junction, and then beyond for about 1.5 miles to near 8600 ft elevation. From just south of the junction with Marion Mountain Trail snow cover is a patchy 60% in the trail to San Jacinto Peak, although much of the sun-exposed route above Little Round Valley is now clear. Snow is thin and patchy in the trail, but due to hiker compaction it is icy. Some hikers will find spikes useful on the upper part of this trail.

On the section of Deer Springs Trail between Strawberry Junction and the top of Marion Mountain Trail (roughly PCT Miles 183-185) six significant treefall hazards remain, mostly from high winds in January. Three more came down in a concentrated area just north of the top of Seven Pines Trail (near Mile 185.2). About ten further trees on the upper trail (above Fuller Ridge) have been down and reported repeatedly for more than a decade but with no action from the State Park. Two significant obstructions are down across the trail between the Suicide Rock Trail junction and Strawberry Junction.

South Ridge Trail is clear of snow from the top of South Ridge Road to Tahquitz Peak (updated 3rd Feb). Four treefall hazards that came down in the trail in strong winds in January were removed by the Trail Report in early February.

There is a well-traveled track through patchy thin snow on the short section of South Ridge Trail on the north side of Tahquitz Peak to Chinquapin Flat. This is icy in places and hikers may find spikes are useful here.

Although the situation has improved somewhat in recent months, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed January 2025).

On the Fuller Ridge Trail section of the PCT there are 12 trees down on the State Park section of the trail (Miles 185.5-189, which have not been maintained by that agency for many years). Several of these pose quite significant hazards for hikers. On the Forest Service section (Miles 189.3-190.5) five significant treefall hazards were removed by USFS late in 2024. Snow cover on Fuller Ridge Trail averages only 50%, but is very localized with sun-exposed sections completely clear and shaded sections still with 1-2 inches depth of snow in the trail.

Trees down on the Strawberry Trail section of the PCT (Annie’s Junction to Strawberry Junction, Miles 180.8-183) have remained uncut by the Forest Service for nearly a decade. About six hazards on this section are thankfully all relatively easy for hikers to negotiate.

The Trail Report heavily trimmed the formerly overgrown Wellman Trail (Annie’s Junction to Wellman Divide) from September 2024-January 2025. The Wellman Trail currently averages about 20% snow cover, confined to the sections that are sheltered under the forest canopy.

In February 2025 the Trail Report cleared Spitler Peak Trail of the six trees that came down in Santa Ana winds in January (bringing to 129 the total number of trees removed by the Report from this trail in recent years). We also removed most of the whitethorn from the central portion of the trail in December 2024. While more brush trimming work is always required, in general the trail is currently in its best condition since at least mid 2023. Spitler Creek continues to flow gently at its various crossings in the upper switchbacks, and Antsell Rock Creek starting flowing gently again in November 2024 (but will dry again this spring without significant further precipitation).

The Trail Report removed the only two new small trees down across Fobes Trail last week. The trail is otherwise largely clear, with only a few minor branch hazards mainly along the lower trail. Snow was gone from this trail (all below 6000 ft) by 31st January.

The Caramba Trail from near Reeds Meadow through Laws Camp and on to Caramba, and the Cedar Trail from Willow Creek Trail to Laws, are euphemistically (and potentially dangerously) described by the Forest Service as “not maintained”. In reality both trails have been abandoned and no longer exist. They are so heavily overgrown, largely with dense whitethorn, which obscures dozens of downed trees, that hikers should not attempt to follow them (regardless of how much you may trust an app). An informal use trail to Laws is much more direct, well maintained, and avoids the bushwhacking of the unmaintained trails (some local Idyllwild hikers dubbed it the “King Trail” when I established the route in 2019). It leaves Willow Creek Trail exactly 1.0 mile from Saddle Junction, 0.46 mile from the Skunk Cabbage turning (trailhead at N 33.7796, W 116.6590). The route descends largely following established deer trails for 1.2 miles, meeting Willow Creek about 0.2 mile upstream from the site of the historic Laws Camp (the remains of which were destroyed by the 2013 Mountain Fire and subsequent flood and treefall damage). One huge tree fell in late 2024 across the King Trail about midway down and requires a minor scramble underneath (that tree will not be cut soon), while another fell in January 2025 close to the bottom of the trail that is relatively easy to cross over. Another five recently downed trees were either removed or worked around in January 2025, when the trail was thoroughly trimmed and cleared. From Laws east to Caramba the route of the original Caramba Trail has been cairned by myself and others and can largely be followed with careful route-finding. My February 2025 survey counted about 120 trees down on this 2.1 miles of trail. It is extremely obscure for the first 0.5 mile east of the Willow Creek crossing, becoming more obvious (but still subtle) as it descends towards Caramba. Very cautious navigation is advised throughout the area.

In late 2024 Willow Creek Trail was nearing its 2020 condition, the last time the original trail route was fully cleared and passable. Four new trees came down on the Forest Service section in January, two of which are large and tricky for hikers to pass. In addition to trees being cut in 2024, whitethorn trimming was largely completed, mainly by volunteers, on the Forest Service side in late summer. On the State Park side localized trimming of the worst patches was undertaken in 2024, and the minor treefall hazards new in 2023/24 were removed, leaving just two major long term downed trees (both easy to pass for hikers).

The Trail Report “adopted” Seven Pines Trail as a priority for maintenance work as the trail had a disproportionate number of lost hiker rescues in the past decade, and both State Park and Forest Service have shown no interest in maintaining the route for years. Since 2020 we have removed 75 downed trees and the trail is trimmed and cleared multiple times annually. As of late 2024 the trail is largely clear of treefall hazards, with three down across the trail in its upper section, all easily passable for hikers. A further half-a-dozen downed trees close to the PCT junction would need to be removed to fully restore the original route of the trail. Although the condition of the trail is hugely improved, Seven Pines remains a genuine wilderness trail unlike the wider, bare, obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains essential for those without considerable experience of hiking this trail. Be aware in particular that Seven Pines Trail becomes most obscure in the mile closest to its junction with Deer Springs Trail/PCT.

The Zen Center Trail continues its serious deterioration that started following the 2013 Mountain Fire, with a combination of vigorous regrowth and treefall hazards further obscuring the route with each passing season. The lower and upper thirds of this trail are partially cairned and not too bad for those who are very familiar with the former route, but even the experienced find navigating the central section tricky. Long trousers, scrambling gloves, and an enjoyment of bush-whacking are all strongly recommended.

UPDATE Friday 7th February at 1330: we caught the southernmost edge of an atmospheric river passing to our north overnight. I hiked to San Jacinto Peak this morning through pleasant misty cloud and periodic drizzle before reaching patchy blue sky right around the Peak. The storm was mild, producing only rain all the way to the highest elevations. Above 9500 ft freezing rain has plastered all surfaces with a thin but treacherous covering of ice. Spikes are strongly recommended at the highest elevations until the emerging sun melts the ice. The most rainfall on the mountain was at Saddle Junction (8100 ft) with 0.51 inch, with 0.41 inch at Wellman’s Cienega (9300 ft), 0.24 inch in Idyllwild, and 0.2 inch at San Jacinto Peak.

——————————————-

The dramatically variable weather that is increasingly typical of the climate this century has certainly been impacting the San Jacinto mountains in the past week. Only five days after the all-too-minor snow storm of last week, it was t-shirt-and-shorts weather in Idyllwild this weekend. Temperatures quickly swung from below seasonal to far above average for February. San Jacinto Peak flirted with an all-time record high temperature for the month of February on 2nd, and may continue to do so on/off throughout the first two weeks of the month (the record high for February is 39.3°F on 22nd in 2021).

Predictably, melting of the light snow from the storm on 26th-27th January has been very rapid. We experienced continuous snow cover in the high country for only four days (the late January storm is described in detail in the previous Report linked here). Total snowfall at San Jacinto Peak since September 2024 has been a pitiful 7.6 inches. Many trails are already functionally clear of snow (details under Trail Conditions below) and the remainder may be within days.

Moderate rainfall is now forecast for the mid elevations overnight on 6th and throughout 7th February. Up to one inch is possible at 5000-6000 ft (e.g., Idyllwild-Pine Cove). The high country may stay largely above the precipitation, with less than 0.1 inch rain currently expected (and temperatures forecast to be too warm for snow). Another storm system is brewing for next week (12th-14th February) with possibilities for more significant snowfall, and further rain at mid elevations.

Conditions are currently suitable for spikes in places above about 8700 ft on the western slope as the established trails have undergone freeze-thaw cycles and the thin snow has become icy due to consolidation by hiker traffic. Snow depths are of course insufficient for snowshoes. Snow depths are insufficient to justify listing at the foot of this posting.

Despite temperatures being above seasonal for February, hikers should be prepared for temperatures near freezing in the high country, and potentially well below freezing when considering wind chill effects on some days (see below for my recent weather observations from San Jacinto Peak).

Survey hikes by the Trail Report every single day throughout the year in the San Jacinto mountains include varied routes to the high peaks including San Jacinto Peak typically 2-3 times per week (more frequently during storms), Tahquitz Peak and area 1-2 times per week, plus a wide variety of other trails on intervening days. On Sunday 2nd we ascended San Jacinto Peak via the classic east side route (using Devil’s Slide, Wellman, and Peak trails) and descended the west side via Deer Springs Trail. This facilitated survey of the highest parts of the PCT in the San Jacinto mountains (roughly Miles 179-181 and 185.5-183.5) plus several of its side trails.

The USFS gate at Humber Park reopened late last week. Even when closed there are nine legal parking spaces immediately below the gate. Vehicles not parked in these spaces have been ticketed in past winters. South Ridge Road is open and is readily passable with AWD/4WD vehicles.

WEATHER

Temperatures are forecast to remain well above seasonal until Tuesday 4th February, when they drop to near (or even slightly below) average for at least a week. Most days into mid February are forecast to be at least partly cloudy.

A warm atmospheric river passing (predictably) to our north this week will raise the marine layer to 6000-8000 ft elevation, potentially producing some light rain between 4th-7th February. Current projections are for less than 0.2 inch of rain across the four days, most likely on Friday 7th, focused on the western slope and west-facing valleys (e.g., much of the PCT in these mountains, Idyllwild-Pine Cove, Garner Valley and the Desert Divide).

The high country is expected to remain above the cloud and receive no significant new precipitation, although there is a slim possibility of a very light dusting of snow on Friday 7th. Due to the warmth of the upper level air mass, temperatures in the high country are forecast to remain 5-10°F above normal on most days into mid February, although westerly winds will remain relatively strong.

At San Jacinto Peak (10,810ft/3295m) on Sunday 2nd February 2025 at 0825 the air temperature was 37.7°F (3°C), with a windchill temperature of 22.1°F (-5°C), 45% relative humidity, and a steady due West wind sustained at 22 mph gusting to 32.1 mph.

At the Peak on Monday 27th January 2025 at 1040 the air temperature was 16.0°F (-9°C), with a windchill temperature of 9.0°F (-13°C), 74% relative humidity, and a remarkably calm hint of a NNW breeze sustained at 0 mph gusting to 2.8 mph.

TRAIL CONDITIONS

For details of water availability prior to the late January minor storm, see an earlier Report (linked here).

There is currently no continuous settled snow in the San Jacinto mountains, a truly unprecedented situation in recorded history this far into the winter months. The thin covering above 9000 ft that fell on 7th January only lasted for a few days despite cold temperatures, while the 4-6 inches of snow from the minor storm on 26th-27th January has already largely melted.

Most hikers will find that traction devices are not required on the trail system, although conditions are currently suitable for spikes in places above about 8700 ft on the western slope (Deer Springs Trail and short parts of the PCT) as the established trails have undergone freeze-thaw cycles and the thin snow has become icy due to consolidation by hiker traffic. Spikes tend to be much more valuable for descending trails than ascending.

There is functionally no snow on trails below 9000 ft on the eastern side trails, e.g., Devil’s Slide Trail is clear, as is most of PCT Miles 178-180. Patches persist in the most sheltered areas above 9000 ft, notably either side of Annie’s Junction (PCT Mile 180.8), then again at 9900-10,100 ft on the Peak Trail and above 10,500 ft around San Jacinto Peak.

The East Ridge Trail (between Miller-San Jacinto peaks) is still 90% snow-covered, but only 1-2 inches deep and with a well-traveled track accurately following the old trail route.

Deer Springs Trail is functionally clear of snow from the trailhead to Strawberry Junction, and then beyond for about 1.5 miles to 8600 ft elevation. From just south of the junction with Marion Mountain Trail snow cover is about 90% in the trail all the way to San Jacinto Peak. Snow is thin and patchy in the trail, but due to hiker compaction it is icy. Some hikers will find spikes useful on the upper part of this trail.

On the section of Deer Springs Trail between Strawberry Junction and the top of Marion Mountain Trail (roughly PCT Miles 183-185) six significant treefall hazards remain, mostly from high winds in January. Three more came down in a concentrated area just north of the top of Seven Pines Trail (near Mile 185.2). About ten further trees on the upper trail (above Fuller Ridge) have been down and reported repeatedly for more than a decade but with no action from the State Park. Two significant obstructions are down across the trail between the Suicide Rock Trail junction and Strawberry Junction.

South Ridge Trail is clear of snow from the top of South Ridge Road to Tahquitz Peak (updated 3rd Feb). Four treefall hazards that came down in the trail in strong winds in January were removed by the Trail Report in early February.

There is a well-traveled track through almost continuous thin icy snow on the short section of South Ridge Trail on the north side of Tahquitz Peak to Chinquapin Flat. This is icy in places and hikers will find spikes are useful here.

Although the situation has improved somewhat in recent months, treefall hazards remain a significant problem along parts of the Pacific Crest Trail, most notably between Antsell Rock and South Peak. Some 56 trees are down across the trail between PCT Miles 170.5-174, with 37 of these, including several serious obstructions that make for slow-going, between Miles 172.5-174 (around and immediately south of South Peak). A further nine smaller obstructions are down from Miles 168.5-170.5 (Spitler Peak Trail to Zen Center Trail). Significant sections of Miles 168.5-175 are also badly overgrown with brush and are in urgent need of major trimming work (surveyed January 2025).

On the Fuller Ridge Trail section of the PCT there are 12 trees down on the State Park section of the trail (Miles 185.5-189, which have not been maintained by that agency for many years). Several of these pose quite significant hazards for hikers. On the Forest Service section (Miles 189.3-190.5) five significant treefall hazards were removed by USFS late in 2024. Snow cover on Fuller Ridge Trail averages only 50%, but is very localized with sun-exposed sections completely clear and shaded sections still with 1-2 inches depth of snow in the trail.

Trees down on the Strawberry Trail section of the PCT (Annie’s Junction to Strawberry Junction, Miles 180.8-183) have remained uncut by the Forest Service for nearly a decade. About six hazards on this section are thankfully all relatively easy for hikers to negotiate.

The Trail Report heavily trimmed the formerly overgrown Wellman Trail (Annie’s Junction to Wellman Divide) from September 2024-January 2025. The Wellman Trail currently averages about 20% snow cover, confined to the sections that are sheltered under the forest canopy.

In February 2025 the Trail Report cleared Spitler Peak Trail of the six trees that came down in Santa Ana winds in January (bringing to 129 the total number of trees removed by the Report from this trail in recent years). We also removed most of the whitethorn from the central portion of the trail in December 2024. While more brush trimming work is always required, in general the trail is currently in its best condition since at least mid 2023. Spitler Creek continues to flow gently at its various crossings in the upper switchbacks, and Antsell Rock Creek starting flowing gently again in November 2024 (but will dry again this spring without significant further precipitation).

The Trail Report removed the only two new small trees down across Fobes Trail last week. The trail is otherwise largely clear, with only a few minor branch hazards mainly along the lower trail. Snow was gone from this trail (all below 6000 ft) by 31st January.

The Caramba Trail from near Reeds Meadow through Laws Camp and on to Caramba, and the Cedar Trail from Willow Creek Trail to Laws, are euphemistically (and potentially dangerously) described by the Forest Service as “not maintained”. In reality both trails have been abandoned and no longer exist. They are so heavily overgrown, largely with dense whitethorn, which obscures dozens of downed trees, that hikers should not attempt to follow them (regardless of how much you may trust an app). An informal use trail to Laws is much more direct, well maintained, and avoids the bushwhacking of the unmaintained trails (some local Idyllwild hikers dubbed it the “King Trail” when I established the route in 2019). It leaves Willow Creek Trail exactly 1.0 mile from Saddle Junction, 0.46 mile from the Skunk Cabbage turning (trailhead at N 33.7796, W 116.6590). The route descends largely following established deer trails for 1.2 miles, meeting Willow Creek about 0.2 mile upstream from the site of the historic Laws Camp (the remains of which were destroyed by the 2013 Mountain Fire and subsequent flood and treefall damage). One huge tree fell in late 2024 across the King Trail about midway down and requires a minor scramble underneath (that tree will not be cut soon) while another one close to Laws is relatively easy to pass over. Another five recently downed trees were either removed or worked around in January 2025, when the trail was thoroughly trimmed and cleared. From Laws east to Caramba the route of the original Caramba Trail has been cairned by myself and others and can largely be followed with careful route-finding. My February 2025 survey counted about 120 trees down on this 2.1 miles of trail. It is extremely obscure for the first 0.5 mile east of the Willow Creek crossing, becoming more obvious (but still subtle) as it descends towards Caramba. Very cautious navigation is advised throughout the area.

Willow Creek Trail is nearing its 2020 condition, the last time the original trail route was fully cleared and passable. Four new trees came down on the Forest Service section in January, two of which are large and tricky for hikers to pass. Many prior treefall hazards on the Forest Service section were cut in 2024. Whitethorn trimming was largely completed, mainly by volunteers, on the Forest Service side in late summer 2024. On the State Park side some localized whitethorn trimming of the worst patches was undertaken in 2024, and the minor treefall hazards new in 2023/24 were removed, leaving just two major long term downed trees (both have simple workarounds for hikers).

The Trail Report “adopted” Seven Pines Trail as a priority for maintenance work as the trail had a disproportionate number of lost hiker rescues in the past decade, and both State Park and Forest Service have shown no interest in maintaining the route for years. Since 2020 we have removed 75 downed trees and the trail is trimmed and cleared multiple times annually. As of late 2024 the trail is largely clear of treefall hazards, with three down across the trail in its upper section, all easily passable for hikers. A further half-a-dozen downed trees close to the PCT junction would need to be removed to fully restore the original route of the trail. Although the condition of the trail is hugely improved, Seven Pines remains a genuine wilderness trail unlike the wider, bare, obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains essential for those without considerable experience of hiking this trail. Be aware in particular that Seven Pines Trail becomes most obscure in the mile closest to its junction with Deer Springs Trail/PCT.

The Zen Center Trail continues its serious deterioration that started following the 2013 Mountain Fire, with a combination of vigorous regrowth and treefall hazards further obscuring the route with each passing season. The lower and upper thirds of this trail are partially cairned and not too bad for those who are very familiar with the former route, but even the experienced find navigating the central section tricky. Long trousers, scrambling gloves, and an enjoyment of bush-whacking are all strongly recommended.

This is a summary of conditions following the only notable (so far) snow storm of winter 2024/25, albeit a minor storm by the standards of the San Jacinto mountains, with snow falling on 26th and 27th January. As is increasingly the trend with a rapidly changing climate in recent years, the snowfall did not fit an obvious altitudinal pattern (in which snow depth generally increases at higher elevations), with storm totals of about four inches at both Idyllwild (at 5550ft) and at San Jacinto Peak (10,810ft). The greatest depths I measured were between 7500 and 9500 ft, peaking at 6.5 inches at Saddle Junction (8100 ft).

The storm system was not a conventional “atmospheric river” originating well to the west, but came from a stalled “cut off” low pressure system around which the jet stream took a sinuous path from northern Canada. Consequently the system was cold, with a dusting of snow below 4000 ft on the morning of 27th, and the slow movement resulted in light snow continuing on/off for most of two days. The bulk of the snowfall was nevertheless concentrated in two phases, in the early hours of Sunday 26th, and then again overnight into the early hours of Monday 27th.

I broke trail to San Jacinto Peak via Devil’s Slide, Wellman, Peak, and East Ridge trails on Sunday 26th January, enjoying the conditions so much that I then repeated the same route, again breaking trail through further fresh snow, on Monday 27th. I recorded short video reports from the Peak on both days (linked here for Sunday 26th, and here for Monday 27th). We broke trail up South Ridge to Tahquitz Peak on 29th, and also put in a trail on the north side of Tahquitz between the peak and Chinquapin Flat.

Currently some trails have not been traveled and most are somewhat obscured by light snowfall. On my descent on the afternoon of 27th I noted that apart from Devil’s Slide Trail (and my own tracks on the PCT northbound ultimately heading to San Jacinto Peak) there were no other broken trails away from Saddle Junction. This will change soon with limited hiker traffic, but cautious navigation is recommended everywhere. Snow depths are listed at the foot of this posting, but note that due to drifting, snow is sometimes deeper in the trails themselves.

Snow depth and structure are both currently suitable for spikes above roughly 7000 ft, and spikes will become increasingly valuable as established trails become consolidated by hiker traffic and undergo freeze-thaw cycles. With rapid melting expected in the next week, the elevation at which spikes are needed will rise quickly. Snow depths are generally insufficient for snowshoes (except possibly around the Tahquitz area meadows for the next day or two) and crampons/ice axe are not required anywhere.

Hikers should be prepared for temperatures below freezing in the high country, and well below freezing when considering wind chill effects until Thursday 30th (see below for my recent weather observations from San Jacinto Peak).

The USFS gate at Humber Park closed on Sunday 26th January. Even when closed there are nine legal parking spaces immediately below the gate. Vehicles not parked in these spaces have been ticketed in past winters. South Ridge Road remains (unexpectedly) open and is readily passable with AWD/4WD vehicles.

WEATHER

Temperatures are forecast to remain below seasonal averages until Thursday 30th, with no significant further precipitation in January, although a possibility of light precipitation on the afternoon of Tuesday 28th. Temperatures are then forecast to rise dramatically to far above seasonal starting Friday 31st, with both daytime highs and overnight lows 10-15°F above average for January/February. The high country will not be spared, with temperatures also some 15°F above normal during the first couple of days of February. This will obviously very rapidly accelerate snowmelt at all elevations.

Temperatures are expected to cool somewhat into the second week of February, with light precipitation currently forecast for Wednesday 5th. This rainfall may be confined to the mid elevations with about 0.25 inch forecast for Idyllwild, with the high country forecast to be above the cloud with no snow expected at this time.

The latest video report from National Weather Service San Diego (linked here) summarizes the recent storm event and describes the weather patterns for the next week.

At San Jacinto Peak (10,810ft/3295m) on Monday 27th January 2025 at 1040 the air temperature was 16.0°F (-9°C), with a windchill temperature of 9.0°F (-13°C), 74% relative humidity, and a remarkably calm hint of a NNW breeze sustained at 0 mph gusting to 2.8 mph.

At the Peak on Sunday 26th January 2025 at 1110 the air temperature was 17.8°F (-8°C), with a windchill temperature of -3.8°F (-20°C), 100% relative humidity, and a cool WSW wind sustained at 9 mph gusting to 15.9 mph.

TRAIL CONDITIONS

For details of specific trail conditions (and water availability) prior to this latest minor storm, see the previous Report (linked here).

All trails above about 6000 ft are at least partially snow-covered. By the afternoon of 27th melting was already underway below 6500 ft, and this will accelerate rapidly over the next few days. Reliable tracks are currently only known to be in place for Devil’s Slide Trail through to San Jacinto Peak via Wellman Divide.

Devil’s Slide Trail has a relatively well-traveled track to follow.

Deer Springs Trail has a reliable track through the snow all the way to San Jacinto Peak as of Thursday 30th.

South Ridge Trail has a lightly traveled posthole track through to Tahquitz Peak as of Wednesday 29th. On the same day we put through a track on the north side to and from the Peak to Chinquapin Flat, where snow depth averages five inches but is drifted to 8-12 inches in the trail.

The Ernie Maxwell Trail has a well-traveled track to follow.

SNOW DEPTHS

Numbers given here are storm totals, measured initially on 26th then again on 27th January 2025, after each of the two main periods of snowfall. Note that average depth is given; some drifting and accumulation has occurred, especially in trails. Altitudes and PCT Miles are approximate.

San Jacinto Peak (10810 ft): 3.5 inches

Wellman Divide (9700 ft): 5.0 inches

Annie’s Junction/approx. PCT Mile 180.8 (9020 ft): 5.0 inches

Tahquitz Peak (8836 ft): 5.0 inches, drifted 8-12 inches on north side trail, and 6-8 inches on uppermost South Ridge Trail

Long Valley (8400 ft): 4.5 inches

Saddle Junction/approx. PCT Mile 179 (8070 ft): 6.5 inches

Devil’s Slide Trail at Humber Park (6550 ft): 5.0 inches (largely melted by 29th)

Idyllwild (at 5550 ft): 4.0 inches, largely melted by afternoon of 27th.
