Pt. Mugu State Park from Boney Mountain — Sycamore Canyon, Laguna Peak, and the Channel Islands from Boney Mountain.

Update on August 17, 2022. As of today, my West Hills weather station has recorded a high of 100 degrees or higher for 12 consecutive days.

It was another triple-digit Sunday. Once again the high in the west San Fernando Valley was forecast to hit one-hundred and something. I’d hope to beat most of the heat by getting an early start and running where it wouldn’t be quite so hot.

I hadn’t been able to get out to Stoney Point Saturday morning, so was looking to do a little easy climbing as part of my Sunday run. I was considering three options: Topanga Lookout Ridge, Strawberry Peak, and Boney Mountain.

Boney Mountain from connector trail above Danielson Road

While none of the three are difficult by rock climbing standards, all require the use of handholds and footholds, good route-finding skills, and good judgment. It is entirely possible to fall on any of them.

The Topanga Lookout Ridge loop is about 8.5 miles long with 2000′ of gain/loss. There are a few short climbing segments on the crest of the ridge that can be accessed from the use trail.

The basic loop up the Western Ridge of Boney Mountain and over Tri Peaks to the Backbone Trail and back to Wendy Drive is about 15.5 miles long with 3400′ of gain/loss. It is longer and more difficult than the Topanga Lookout Ridge loop.

The loop over the top of Strawberry Peak from the Colby Canyon Trailhead is about 12 miles long with 3100′ of gain/loss. There is some class 2/3 climbing on the west side of Strawberry, and it is essential to stay on route. There have been a number of rescues of those attempting to climb the peak.

It was a few minutes past six when I pushed the start button on my Garmin and jogged down the hill from the trailhead at Wendy Drive. I’d run about a half-mile when I heard another runner behind me. We chatted for a couple minutes and I learned he was preparing to do the Wonderland Trail around Rainier and then the Bear 100.

We were both going to the same area, but by different routes. I was climbing Boney Mountain’s Western Ridge and then working over to the Backbone Trail. He was doing an out and back to Sandstone Peak via Upper Sycamore, Sycamore Canyon, and the Backbone Trail. We would run into each other again at the Danielson Multi-Use Area on the way back to Wendy Drive.

As always, the climb up the Western Ridge (Mountaineer’s Route) was enjoyable. The rock climber in me always wants to check out potential lines, but this morning there wasn’t much time for that. The longer it took to get up Boney, the hotter it was going to be later in the run!

The temperature was already in the eighties when I reached the Backbone Trail. Before the fires and floods of past decade, the run down the Chamberlain segment of the Backbone Trail was one of the better running descents in the Santa Monica Mountains. From the Tri Peaks Trail junction to the Old Boney Trail it drops about 1500′ over three miles. Today, except for the stretch of trail near Chamberlain Rock, it was nearly back to its original form.

Holly-leaved cherries along the Chamberlain segment of the Backbone Trail

As in other areas of the Santa Monica Mountains, the effect of the heavy December rains was evident. The red shanks, and chaparral in general, seemed to be greener. This year there is a bumper crop of holly-leaved cherries, which must make the coyotes happy. Unlike last year, it looks like there should be some Christmas berries this Winter, since a number of Toyon were covered in green berries.

On the way down the Chamberlain Trail I started to fret that the water at Danielson might not be turned on. The water faucets in Sycamore Canyon are usually dependable, but on a run a few years ago the water system was turned off for servicing. Or what if there had been a drought-related water supply issue?

It turned out the water was still on, and I drank a lot of it. The remainder of the run went well, although I was a little surprised that the sensor on my pack recorded temps in the nineties in Sycamore Canyon. I had expected the south-facing stretch on Danielson road to be torrid, but a nice breeze kept the temperature tolerable.

The Curve Fire started on Labor Day Weekend 2002, along Highway 39 in the San Gabriel Mountains. Between Mt. Islip and Throop Peak, the fire burned over the crest and down to Angeles Crest Highway. Between Throop Peak and Mt. Baden-Powell, the fire generally burned up to, but did not breach the crest.

The Curve Fire killed many trees, including some large, old-growth trees. The most common species along the trail between Mt. Islip and Throop Peak are white fir, Jeffrey pine, sugar pine, and lodgepole pine. Incense cedar also grows in the area, and limber pine is found on and to the east of Throop Peak. Here is a cross-section of a tree along the PCT about 3.0 miles from Islip Saddle. It is representative of the older trees killed in the Curve Fire.

Prior to the Curve Fire, the FRAP geodatabase of California fires has no record of a large fire that burned along the crest of the San Gabriels between Mt. Islip and Mt. Baden-Powell. The FRAP record extends back to the early 1900s, when the San Gabriel Timberland Reserve became Angeles National Forest. A study of mercury levels in Crystal Lake and newspaper accounts suggest the possibility that a large fire occurred in this area in 1878, or about 124 years before the Curve Fire.

I’ve run and hiked the PCT between Islip Saddle and Mt. Baden-Powell for many years, so have had the opportunity to follow the regrowth of conifers where the Curve Fire burned over the crest. Studying conifer regrowth in this area can provide insights into regrowth in the 2009 Station Fire and 2020 Bobcat Fire burn areas, and in areas burned by more than one of these fires.

The locations of the stands are shown in this Google Earth image, along with the areas burned by the Curve and Bobcat Fires. Of these four areas, Stand #1 is the only one burned by the Curve Fire and Bobcat Fire.

Stand #1

A June 2020 photo of conifer regrowth after the 2002 Curve Fire. These trees were obliterated by the Bobcat Fire.

This stand of young Jeffrey pines looked very healthy in June 2020. The area is about 1.5 miles east of Islip Saddle on the PCT, at an elevation of about 7440 ft. At that time a tree adjacent to the trail stood well overhead.

I almost ran past this area in July 2022. I had to double-check the mileage on my watch. Where were the trees? Here is a comparison of the area before and after the Bobcat Fire.

The young trees were more vulnerable than the mature trees in the area. Eighteen years of Curve Fire regrowth were completely obliterated.

Stand #2

This area of young trees is between Windy Gap and Peak 8426, about 3.0 miles east of Islip Saddle on the PCT, at an elevation of about 7900 ft. Some old-growth Jeffrey pines were killed here. This is what the area looked like on May 30, 2010.

Now the size of the trees ranges from seedlings a few inches tall to this very robust Jeffrey pine that is well over head height.

Stand #3

This area of young trees is on broad ridge, west of Mt. Hawkins, about 4.2 miles east of Islip Saddle on the PCT. The Curve Fire ran down the ridge to Hwy 2, killing hundreds of trees. The elevation at the PCT is about 8500 ft.

Stand #4

This area of young trees is on a south-facing slope, just west of Throop Peak, about 5.1 miles east of Islip Saddle on the PCT. The elevation is about 8900 ft. Because of its aspect, the new trees are taller than in the other areas photographed. Here’s what this area looked like in May 2012, June 2016, and July 2022.

Nope, my eyes weren’t deceiving me, the hiker was carrying his full-size poodle up the trail.

I was running down the PCT, east of Islip Saddle, after a run/hike to Mt. Hawkins and Throop Peak. I’m guessing the hiker was carrying his dog to keep it out of the Poodle-dog Bush on both sides of the trail.

Poodle-dog Bush (Eriodictyon parryi) is a fire-follower that can cause severe dermatitis in some people. In this case the plants sprouted following the 2020 Bobcat Fire.

The last big outbreak of Poodle-dog Bush followed the 2009 Station Fire. At that time many people were unfamiliar with its potential effects, and were caught off-guard.

The plant can get you in a couple of ways — the plant’s resin can affect sensitized people in a manner similar to poison oak, and the plant’s numerous hairs can break off and irritate the skin.

My experience with Poodle-dog Bush is described in the posts Contact Dermatitis from Eriodictyon parryi – Poodle-dog Bush and Getting Over Poodle-dog Bush Dermatitis.

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.

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.

Update February 2, 2024. Bush poppy (Dendromecon rigida) has become a prolific and dominant fire follower in this area.

The 2021 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.
