Rockslide and water update 17th June 2021

Temperatures this week will continue to be exceptional for June in the San Jacinto mountains. Tuesday 15th set a record high temperature for that date in Idyllwild (99°F), while 120°F in Palm Springs broke the daily record by four degrees (both locations passing records set in a heatwave in June 1961). If you plan on hiking prior to 21st, please pay particular attention to forecasts and plan accordingly for very hot, very dry conditions.

The major trail news this week is the removal on Monday 14th June of the rockslide at PCT Mile 172.5, just north of Antsell Rock. I have before, during (!), and after video available here. The blasting was a success, making this section of the PCT significantly safer, and thank you to USFS for inviting the Trail Report to assist with the project. The trail tread was improved both before and after the blasting by an American Conservation Experience (ACE) volunteer crew, and is now passable with care by hikers (but remains too narrow for stock).

Water conditions in the high country continue to deteriorate rapidly. This week’s weather will not help the situation. The current status of many key springs and creeks is described below.

Be rattlesnake aware. Southern Pacific Rattlesnakes (Crotalus helleri) have been seen on multiple trails at elevations up to near 9000ft.

Mountain Lions are thankfully always common and widespread locally. One of my camera traps in the San Jacinto mountains near Idyllwild obtained excellent footage of a healthy adult passing by on 22nd May and again on 5th June 2021.

The U.S. Forest Service ranger station in Idyllwild remains closed due to USFS coronavirus protocols. It is not expected to reopen before late July. Hiking and camping permits are required for USFS lands, and are available at the kiosk outside the ranger station. The State Park ranger station reopened months ago.

Black Mountain Road reopened on 23rd April, and the Black Mountain Fire Lookout on 23rd May. Boulder Basin campground reopened on 22nd May along with other USFS seasonal campgrounds. Tahquitz Peak Fire Lookout reopened for the season on Sunday 30th May.

WEATHER Temperatures will be far above normal (especially overnight lows), and potentially dangerous, until Sunday 20th, accompanied by low humidity. Temperatures return to near seasonal averages starting Monday 21st June. There is no precipitation in the forecast. Fire risk is severe.

At San Jacinto Peak (10,810ft/3295m) on Wednesday 16th June 2021 at 0700 the air temperature was 60.9°F (16°C), with a windchill temperature of 56.3°F (8°C), 26% relative humidity, and a pleasantly fresh NE wind sustained at 12 mph gusting to 17.8 mph.

At the Peak on Monday 7th June 2021 at 0755 the air temperature was 49.4°F (10°C), with a windchill temperature of 43.3°F (6°C), 28% relative humidity, and a brisk SSW breeze sustained at 6 mph gusting to 11.8 mph.

TRAIL CONDITIONS

Trails throughout the San Jacinto high country cleared of snow in early May. Water conditions are a concern, with most springs and creeks already having flows more typical of autumn.

Many trails have accumulated treefall hazards from the past two winters, passable with care by hikers but not for stock. Some are described below, others include: PCT between Strawberry Cienega and Deer Springs camp (PCT Miles 182-185, about 12 trees down), Fuller Ridge Trail near its northern end (PCT Miles 189.1-190.2, three trees), and upper Spitler Peak Trail (five trees).

Excellent work by the ACE crew in anticipation of the rockslide blasting resulted in the clearing of many treefall hazards from Red Tahquitz to Antsell Rock (PCT Miles 172.5-175). Nevertheless about 20 hazards remain, including at least seven major obstructions for hikers. USFS volunteers had previously cleared all treefall hazards from Tahquitz Creek to Red Tahquitz (Miles 175-177).

Willow Creek Trail has 12 downed trees on its Forest Service section, including a couple of large, heavily-branched trees that are somewhat challenging to pass. USFS has been notified. There are several additional trees down on the State Park section of the same 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 (which both nominally reopened in late 2018) are optimistically described by the Forest Service as “not maintained”. In reality parts of these trails no longer exist with significant sections of both so heavily overgrown that I strongly advise hikers do not attempt to follow them. Experienced hikers have reported getting lost in this area since summer 2019. An informal use trail to the Laws area is much more direct and completely avoids all of the challenging bush-whacking of the unmaintained trails (local hikers have kindly dubbed it the “King Trail“). It leaves Willow Creek Trail exactly 1.0 mile from Saddle Junction, 0.45 mile from the Skunk Cabbage turning (trailhead at N33°46’46”, W116°39’32”, WGS84). The cairned trail descends largely on established deer tracks for 0.9 mile. Be advised that it is a use trail, becoming somewhat less obvious as it nears Willow Creek. From Laws east to Caramba the route of the old Caramba Trail has become increasingly tricky to follow, especially for the first 1.2 miles east of Laws. Closer to Caramba the trail is relatively obvious (for those familiar with the route prior to the 2013 Mountain Fire). Cautious navigation is required throughout this area.

Seven Pines Trail has had limited hiker traffic since November 2018. There are 35 treefall hazards on the trail, four large ones on the short Forest Service section, and the remainder in the State Park, based on my May 2021 survey. Cautious navigation is recommended for those who are not familiar with hiking this trail. Dark Canyon Road has been closed since early 2019, and there is currently no vehicular access to Seven Pines trailhead, although the road is expected to reopen soon.

WATER STATUS: Eastern slope

The Round Valley pipe is flowing. Creeks in Round Valley and Tamarack Valley are already dry (in 2020 neither dried until August).

Both the northern and southern springs at Wellman’s Cienega are flowing gently. These are the sources for Willow Creek, which is flowing relatively weakly where it crosses the Willow Creek Trail.

Tahquitz Creek is flowing steadily at the northern end of Little Tahquitz Meadow. It is also flowing further upstream at its source (known locally as Grethe Spring) where it crosses the PCT at approx. Mile 177.

Tahquitz Creek at the north end of Little Tahquitz Meadow, 14th June 2021.

The small creek in Tahquitz Valley is already dry where it crosses the trail, four months earlier than in 2020. However about 100 yards upstream there is a little surface flow with pools just about suitable for filtering.

Candy’s Creek – that flows through Skunk Cabbage Meadow and then crosses the remaining visible section of Caramba Trail near Reeds Meadow – is currently flowing gently in both locations.

WATER STATUS: Western slope

The North Fork of the San Jacinto River is flowing steadily where it crosses the Deer Springs Trail and again downstream where it crosses the Fuller Ridge Trail on the PCT (approx. PCT Mile 186.2).

The creek in Little Round Valley is flowing very weakly for only a few hundred feet and dries up before leaving the Valley. It is currently marginal for filtering. There is unlikely to be water in LRV beyond June this year. The same creek dried up where it crosses Fuller Ridge Trail (at about PCT Mile 186.4) in April.

Shooting Star Spring (below Little Round Valley but above the North Fork of the San Jacinto River crossing) is flowing weakly and is poor for filtering.

The Deer Springs stream crossing at the PCT (approx. PCT mile 185.6) is now flowing very weakly but remains adequate for filtering.

The tiny spring about 0.4 miles north of Strawberry Junction (known colloquially as Switchback Spring) is trickling. I reworked the tiny pool and there is just adequate depth from which to filter water.

The little creek at Strawberry Cienega (PCT mile 183.0) is functionally dry.

On Devil’s Slide Trail, Middle Spring barely continues to trickle. Other springs on this trail are dry.

On the Ernie Maxwell Trail, the crossing of Chinquapin Creek just below Humber Park is largely dry where it crosses the trail. However, there are small fresh pools just upslope from the trail (this creek is an important source of water for the many dogs walked on this trail).

The faucet at Cinco Poses Spring, about 4.5 miles up Black Mountain Road, was flowing well last week.

WATER STATUS: Desert Divide

Live Oak Spring (N 33 37 21, W 116 33 24) Flowing well. The most reliable water source on the Desert Divide.

Cedar Spring (N 33 40 36, W 116 34 35) Flowing well. Easiest access is the trough about 60 yards upstream from the trail to the campsite.

Apache Spring (N 33 43 11, W 116 37 13) Barely trickling, not now reliable.

Spitler Peak Trail Descending the trail from the PCT there are five water crossings. The first two, at 0.9 and 0.95 miles down, cross a tiny side creek which is largely dry and should be ignored. The next crossing, at 1.1 miles down, is Spitler Creek and is the best source of water (currently flowing gently). The next two crossings are the same creek, but for obvious reasons it is best to fill up at the highest of the three crossings.

Antsell Rock Creek (N 33 41 52, W 116 39 08) Right by the Spitler Peak Trail trailhead on Apple Canyon Road, Antsell Rock Creek is flowing steadily. Just on the upstream side of the road there is excellent access to the creek. Useful if hikers are descending the Spitler Peak Trail.

Thank you hikers for taking the time to read this. While labor and time is volunteered, the San Jacinto Trail Report completely depends on small private donations to cover costs. Every year seems to be challenging and 2021 has been no exception, so every contribution, no matter how small, is truly valuable. If you have found this Report useful, please consider visiting the Donate page. Thank you.
