Mt. Baldy from Wrightwood Via the Acorn and North Backbone Trails

The last time I was on this part of the North Backbone Trail it was bitterly cold and very windy. Today it was just very windy. Even though the air temperature was in the 70s, the “wind chill” was enough that I was considering grabbing the sleeves and shell from my pack.

I stopped in the lee of a sprawling, stunted lodgepole pine and enjoyed a moment of relief, shielded from the wind. But there wasn’t that much mountain above me, and I resumed zig-zagging up the final steep stretch of trail. Climbing a little higher, I could see the trail sign that marks the top of the North Backbone Trail.

Mt. Baldy from Wrightwood is a more difficult variation of the North Backbone Trail route. Instead of driving to the North Backbone Trailhead on East Blue Ridge Road (F.R. 3N06), you run/hike to the trailhead using the Acorn Trail and a short stretch of Blue Ridge Road or the PCT. (The dirt road is slightly shorter, but you don’t have to dodge off-road vehicles when on the PCT.)

Including Pine Mountain (9648′) and a short detour to the top of Dawson Peak (9575′), the regular North Backbone route is about 8 miles long and gains/loses around 4700′. Starting in Wrightwood at the small parking area on Acorn Drive ups those totals to around 15 miles, with a 6800′ gain/loss.

A mix of hikers and trail runners were scattered across the broad summit of Mt. Baldy (10,064′). The wind wasn’t as strong on the summit as it had been on the North Backbone. Smoke from the Western wildfires reduced the visibility, but the air quality and view were still pretty good.

Like many mountains, the adventure didn’t end on the top of the peak. The elevation gain on the way back to Wrightwood is significant, and much of the downhill demands close attention — especially on tired legs. I squeezed the water bladder in my pack and tried to estimate how much was left. The day was just going to get warmer, and I hoped it was enough to get me back over Dawson Peak and Pine Mountain. On the way up, I’d stashed a small water bottle near the North Backbone Trailhead, and that would help on the final few miles.

Other than initially running past my water stash, the descent went well. Once on the PCT I could run normally — well, more or less normally — and it didn’t take long to get over to the Acorn Trail.

When doing the AC100 and related training runs, I’d run/hiked up the Acorn Trail a number of times, but I’d never run down it. After all the rough trail on the North Backbone, it was great to be able to cruise down through a forest of pine and fir on a well-groomed trail! Here’s an elevation profile of the route.

Red Box – Bear Canyon – Switzer’s Loop – July 2021

I’d decided to stay off the higher peaks because a combination of monsoon moisture and an upper level low was probably going to produce some thunderstorms in the high country. The action was forecast to stay east of of the Mt. Wilson area, but there was a chance there might be enough clouds to knock the temperature down a few degrees.

But a chance is just that, and the day dawned mostly clear and warm at Red Box. A few feathery high clouds had no effect on the sun, and as I jogged up Mt. Wilson road to the start of the Mt. Disappointment Trail, the temperature was already in the 80s.

I was doing a 15-mile version of the Red Box – Bear Canyon loop. The main trails that make up this version of the loop are the Mt. Disappointment Trail, San Gabriel Peak Trail, Mt. Lowe Fire Road, Upper Bear Canyon Trail, Bear Canyon Trail, and the Gabrielino Trail. Refer to a trail map for additional details.

As it turned out, the Bear Canyon Trail was in the best condition I’ve seen in years. Thank you Bear Canyon Trail Crew! While still rustic, the trail between the old cabin site and the trail camp was a bit more worn than usual, and a little easier to follow. In some years it can be much more difficult to navigate.

No one was camped at Bear Canyon Trail Camp. The condition of the creek was similar to 2018. There were a few small pools here and there, but almost no surface flow. In addition, strict fire restrictions are currently in effect. See Forest Order No. 05-01-21-04.

The dry conditions had one benefit — I didn’t have any issues with stinging nettle. There was still plenty of poison oak, but it was drying out and turning red. For the most part the poison oak could be avoided.

The Gabrielino Trail between Switzer Falls and Switzer’s Picnic area was as busy as usual, including one hiker walking their cat!

As I worked up the Gabrielino Trail above Switzer’s, I kept looking for those monsoon clouds. Temps in the sun on the exposed trail was in the high 90s, and it was a relief to finally get to the more shaded sections near Red Box.

This 17 mile trail run and hike is a longer version of the Inspiration Point to the Pine Mountain Juniper adventure run. Additional details and photos can be found in that post.

The adventure combines a seven-mile run on the PCT along Blue Ridge with a strenuous 1.5 mile, 1500′ climb up the North Backbone Trail to the summit of Pine Mountain (9648′). The Pine Mountain Juniper, estimated to be 800-1000 years old, is found at the 9000′ level of the North Backbone Trail.

On the way out I was glad to see the PCT had been rerouted around a steep, rocky stretch of trail below Mountain High West’s snow-making pond. I stayed on the PCT except for a very short section of dirt road between the top of the Acorn Trail and the overlook of the huge Wright Mountain landslide scar. The single track is more pleasant, and I didn’t have to worry about vehicles or their dust. I left the PCT when I was directly above the North Backbone Trailhead. A short path descended to the road.

The North Backbone Trail was as steep as it has always been. It’s not a constructed and maintained trail, but one that has evolved through use. Stretches of it are very steep, loose and rocky. The tree on Point 8555 that was struck by lightning in 2006 has finally fallen. There must be a lot of lightning activity here because a nearby pine had been recently struck by lightning.

The North Backbone Trail seems to be getting more attention these days. This adventure could be extended to include Dawson Peak and Mt. Baldy. A similar route was part of the 44-mile Big Pines Marathon — possibly the first mountain ultra in the U.S.

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.

Trippet Ranch Loop After the Palisades Fire

The Palisades Fire began the evening of May 14, 2021 in Santa Ynez Canyon, near Michael Lane in Pacific Palisades. According to the Los Angeles Fire Department Palisades Fire incident page, 1202 acres were burned, one firefighter was injured, 710 structures were threatened, but no structures were damaged or destroyed. The fire was fully contained on May 26.

Most of Topanga State Park was closed as a result of the fire. The Park reopened, with restrictions, on June 11. On June 13, I found myself chugging up the Garapito Trail toward Eagle Rock, and wondering what I was going to find.

I was doing a variation of one of my favorite trail runs in the eastern Santa Monica Mountains — the Trippet Ranch Loop.

This trail run links together several single-track trails and fire roads between Marvin Braude Mulholland Gateway Park (Top of Reseda) and Trippet Ranch. With the addition of an out and back segment on the the Santa Ynez Canyon Trail, the route included all the trails impacted by the fire.

Here are a few photos taken along the way.

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.
