Rabbitbrush Along the PCT Near Mt. Hawkins

Rubber rabbitbrush (Ericameria nauseosa) along the PCT, near Mt. Hawkins

From mid Summer into Fall, the vibrant yellow flowers of rabbitbrush add a refreshing hit of color to the greens, grays, and browns of the San Gabriel Mountains.

The title photo was taken along the PCT, at an elevation of about 8600′, near Mt. Hawkins. The area was burned in the 2002 Curve Fire. Here, and elsewhere in the burn area, new trees — now in their teens — are slowly replacing some of the trees lost in the fire.

After the Palisades Fire – Snake Tracks and Monkeyflowers

Rattlesnake track on Eagle Springs Fire Road following the May 2021 Palisades Fire

The rattlesnake track above was one of several snake tracks on Eagle Springs Fire Road this morning. This area, which is below Eagle Rock in Topanga State Park, was severely burned in the May 2021 Palisades Fire.

This photo of a blooming bush monkeyflower in the same area underscores the resilience of the chaparral biome.

San Gorgonio Mountain – June 2021

For the second time this month, I was crossing San Gorgonio’s summit plateau and relieved to be nearing the summit. Most of the uphill was done! My route was the same both times — South Fork, Dollar Lake, Divide, and Summit Trails up; then the Summit Trail, Sky High, Dry Lake, and South Fork Trails down. Here is an interactive, 3D terrain view of the route.

The changes along the South Fork Trail in just two weeks were remarkable to see. It may be Summer in the lowlands, but Spring was still in progress on the mountain. Withered-looking black oaks were now flush with leaves; newly sprouted ferns had unfurled, filling areas of the understory with bright green fronds; colorful wildflowers seemed to have appeared overnight.

Over the past two weeks, trailwork continued in the area. The start of South Fork Trail was rerouted for a second time since the 2015 Lake Fire, avoiding a very steep, root-filled section. In a continuing battle, some of the dead trees that had fallen on the trail had been cleared.

Earlier in the month a few small patches of snow could still be seen on the mountain, but today it was nearly gone. Only one tiny, stubborn patch of snow remained on the crest, near the summit. Most of Southern California recorded below average precipitation this past year. According to OntheSnow.com, nearby Snow Summit recorded 121″ total snowfall in the 2020-2021 season. This compares to 110″ in the 2019-2020 season and 143″ in the wet 2018-2019 season. A paltry 36″ was reported in 2017-2018.

As I started up the final rocky hill to the top of San Gorgonio, a small group of hikers scrambled down from the summit. As was the case earlier in the month, the summit area was nearly empty. On an ascent in September 2019 — when wilderness permits were not required — I’d estimated 40-50 people on, or around, Gorgonio’s summit. The restoration of the permits seemed to have made a big difference.

Relaxing on the summit, I looked over at another high point about 100 yards to the ESE. The traditional U.S.G.S. 1996 7.5′ San Gorgonio Mountain Quadrangle isn’t high enough resolution to show this secondary summit. From the official summit, the other point looks higher, and vice versa.

Out of curiosity, following the run I checked the high resolution 3DEP Lidar data for San Gorgonio. It resolves the twin summits, and indicates the official (west) summit is about three feet higher.

In 1989, the “San Bernardino County Surveyors” determined the elevation of San Gorgonio Mountain to be 11,501.6 feet. They placed this small marker on summit. The USGS page Global Positioning Application and Practice discusses some higher precision GPS equipment and survey methods. The elevation of the mountain has probably shifted a little since that measurement was done.

After comparing notes with a runner doing the clockwise version of the route I was doing, I headed back down the Summit Trail to its junction with the Sky High Trail.

By their very nature, mountain trails are scenic, but the Sky High Trail is exceptionally so. Running down the Sky High Trail is what running in the mountains is all about. It is spectacular! That doesn’t mean it’s a cakewalk. The trail is rough, rocky, and crosses steep slopes. As with any trail on such terrain, snow on the trail can be a serious issue.

The Sky High Trail ends at Mineshaft Saddle. From here, I picked up the Dry Lake Trail and continued down, down, down. Above Dry Lake, a section of trail pummeled by an avalanche in 2019 had been restored. Continuing, the trail winds down through a complex of glacial moraines above Dry Lake. and then follows the margin of a large moraine down to Dry Lake. The lake dried up early this year, and was already dry on June 6.

It can be very warm in the afternoon on the Dry Lake Trail between Dry Lake and South Fork Meadows, but today gusty winds kept the temperature moderate. At South Fork Meadows, I gulped down a liter-bottle of water, enjoying the cool shade, and then finished the run.

San Bruno Mountain and Windy Hill Trail Runs

With vaccinations on the increase and Covid on the decline, it was wonderful to once again be able to visit family.

As we always try to do, Brett and I got in a couple of runs. We usually do at least one run that is new to me, and there are certainly plenty from which to choose in the Bay Area.

Our first run was on San Bruno Mountain. We’d previously done the Ridge Trail, so this time opted to do a variation of the Summit Loop. The parking lot at the base was was closed, so we started the run using the Old Ranch Road Trail. This was a plus because it added a little mileage and there were a lot of wildflowers along the trail, including monkeyflower, iris, lupine, yellow paintbrush, daisy, and foxglove.

It was an excellent run on single-track trail. As is the rule on San Bruno, it was a bit breezy, with hazy views of the surrounding communities and the Pacific. An island of open space in an urban sea, San Bruno Mountain is a miracle of land conservation, and an area to be relished. Here is a map of trails in the area.

The next day, after watching a spirited youth soccer match, we headed south on 280. On the way, Brett filled me in on the runs he likes to do in Windy Hill Open Space Preserve and Huddart Park. We couldn’t go wrong with either choice but finally decided to save Huddart Park for another day.

Windy Hill Open Space Preserve is on the northeast-facing slopes of the Santa Cruz Mountains above Portola Valley. We parked near the Alpine Trailhead and ran up the road to the Eagle Trail. Corte Madera Creek was running, but low. Although the grasses along the trail were green and the undergrowth was relatively lush, I suspect the conditions were more like July than May. Open hillsides looked mid-Summer dry and the lichen on the trees was drab and desiccated.

Like the rest of California, the Santa Cruz Mountains have seen well below average precipitation this rain season. One station near Windy Hill, Woodside 3.4 S, recorded only about 28% (12″) of normal precipitation from October 1 to May 19. Another station, Skyline Ridge Preserve, recorded about 41%  of normal (16.5″) from October 1 to May 3.

From the Eagle Trail/Private Road we turned onto the Razorback Ridge Trail. According to my Garmin track, the Razorback Ridge Trail gains 1000′ or so over 2.4 miles to its junction with the Lost Trail. It’s all runnable, switch-backing up a thimbleberry and fern-lined trail, shaded by California bay trees.

While the Razorback Ridge Trail continues up another 0.4 miles to Skyline Blvd., we turned right onto the Lost Trail. This trail parallels Skyline as it works in and out of the tributary ravines of Jones Gulch, on its way over to the Hamms Gulch Trail. Along the way there were views across the valley to Mt. Diablo, some 40 miles distant. Western columbine was blooming along the trail, its bright red color complimenting the green theme.

At the top of Jones Gulch, there is an impressive, old-growth Douglas-fir. At chest height, it is about as wide as Brett is tall. This would put its diameter at over 72″ and its circumference at over 220″, suggesting an age in the neighborhood of 350 years.

The run down the Hamms Gulch Trail was as good as the run up Razorback Ridge. Given the weather was nearly perfect for a hike or run, we were surprised to see only a dozen or so people on the trail.

From where we were parked the run worked out to about 8 miles, with about 1500′ of gain/loss. Here is a trail map of the area, and here is an interactive, 3D terrain view of my GPS track of the loop.

According to the Dibblee geologic map of the area, the strata are part of the Modelo Formation. And… the Modelo Trail passes directly over the top of the hill.

The photo was taken on a run from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve to the Cheeseboro Ridge Trail and back.

It was a chilly 45 degrees in the canyon, and I had already resigned myself to having to wade across Big Tujunga Creek. But I didn’t even get my shoes wet. The water level was low enough that the large rocks placed across the creek were high and dry.

It was a good start to what was to be an excellent run and hike. As I gained elevation, it was evident there had been recent work on the trail. Trimmings from the brush along the trail were still green, and in several spots the tread had been freshly manicured. The higher I climbed, the more work had been done. In a couple of places, substantial washouts had been repaired.

Last year, the trailwork ended abruptly about halfway up the trail. Not so this year. An impressive amount of work had been done to clear the trail of a tortuous mix of dead scrub oaks and thorny brush. Without having to crawl over, around, and through those snarls, my roundtrip time to the summit and back was a full hour faster than last year. Many thanks to whoever worked on the trail!

Although rainfall has been below normal this rain season, there were still some wildflowers blooming along the trail. Among them were bush poppy, chaparral currant, and hoary-leaved Ceanothus.
