Waterman Meadow on the Three Points - Mt. Waterman Trail

There are a variety of trail runs that can be done from Three Points in the San Gabriel Mountains. The Pacific Crest Trail and Silver Moccasin Trail pass through Three Points, and the Three Points – Mt. Waterman Trail starts near Three Points. Additionally, several Forest Service roads in the area can be used to connect trails, extend routes, or explore the surrounding area.

The previous weekend. I’d done a loop from Three Points that started on the Silver Moccasin Trail, ascended the Mt. Hillyer Trail, and then descended forest roads to the PCT. The PCT was followed back to Three Points.

It can get hot in the middle elevations of the San Gabriels, but on this run a thick layer of high clouds kept the temperature in the 60s and 70s. There was a steady stream of through-hikers on the PCT, and as usual, they were enthusiastic about being on the trail. Flannel bush was in full bloom, and paintbrush and lupine added patches of energizing color to the trails.

This weekend, I returned to Three Points to do one of my favorite trails in the San Gabriels — the Three Points – Mt. Waterman Trail (10W04). It is an out-of-the-way trail with a capricious character. On one run, I counted more than 40 trees and limbs across the trail, but on another, none. The trail is defined by use, and depending on the amount of use, some sections may be challenging to follow. All of that is part of the fun.

I usually do the Three Points – Mt. Waterman Trail as part of the Three Points Loop. Today, I opted to do the run as an out and back to the top of Mt. Waterman (8038′).

It was a good day to do that because the San Gabriel Mountains Trailbuilders had been hard at work, and the Three Points – Mt. Waterman Trail was in the best shape I’ve seen since May 2018. Several large trees had been cleared from the trail. I didn’t have to climb over or go around a single tree. Painful mountain whitethorn and other prickly bushes had also been trimmed. The trail was well-defined and generally easy to follow.

Waterman Meadow was bright green with newly unfurled fronds of bracken fern. Among the Spring wildflowers along the trail were golden yarrow, mountain phlox, southern mountain lupine, beardtongue penstemon, wallflower, and snow plant. Along lower elevations of the trail, deer brush was covered in flowers. There was still a little Poodle-dog bush here and there.

Several granite crags are scattered across Mt. Waterman’s summit. Since I wasn’t doing the loop around Waterman, I had time to do a little bouldering. I didn’t recall exactly where the summit benchmark was, but eventually found it on one of the smaller crags.

It’s rare to encounter anyone on the Three Points – Mt. Waterman Trail, but the trail that ascends Mt. Waterman from Buckhorn is very popular. As I ran down from the summit, I began to wonder if I would see anyone when I encountered a small group of hikers coming up from Buckhorn. Those were the last hikers I saw until I was nearly back to Three Points.

The hike to Twin Peaks from Buckhorn used to be another popular option. In 2020, the Bobcat Fire decimated the north face of Twin Peaks. Curious to see the impacts, I did Twin Peaks in 2022. Some stretches of the use trail escaped the fire and most of east summit was not burned. In 2022, there weren’t many fallen trees on the trail, but there are likely more now.

Except in wet years, there are no dependable water sources on the Three Points – Mt. Waterman Trail. There’s a spring partway down the Twin Peaks Trail, but I haven’t visited it enough times to know if it is reliable. It can be hot on this trail, even when there isn’t a heat wave. Although temperatures were relatively moderate today, I drank nearly all the water I had carried.

This high-resolution, interactive, 3D terrain view shows the Three Points Loop (yellow) along with the spur trail to the summit of Mt. Waterman (red). The out and back to the summit of Mt. Waterman is about 15 miles RT with about 3100′ of gain/loss. The Three Points Loop ranges from 20 to 25 miles, depending on the variation.

Fire Followers Along the Fossil Ridge Trail

Fire Followers Along the Fossil Ridge Trail. May 25, 2025.

Recently, while doing the Topanga Lookout Ridge Loop, I was surprised to find that the “Closed” sign and tape blocking access to the Fossil Ridge Trail had been removed. The Fossil Ridge Trail has been closed since the Palisades Fire and was closed when I did the Hondo Canyon Trail on May 4.

This 0.6-mile segment of the Backbone Trail connects the top of the Hondo Canyon Trail to Topanga Ridge Mtwy, near the Lois Ewen Overlook. From the overlook, the Backbone Trail continues west to Saddle Peak and then on to Malibu Canyon and other trailheads.

I decided to check out the initial stretch of the Fossil Ridge Trail, intending to turn around if it was obviously damaged, overgrown, or there was some other issue.

What I found was a trail that had been recently groomed and a hillside full of wildflowers — thousands of wildflowers. The number of large-flowered Phacelias — a showy, purple fire follower — was extraordinary. Also decorating the trail were caterpillar Phacelia, collarless poppy, bindweed, star lily, Catalina mariposa lily, yellow mariposa lily, blue Dicks, and false mustard.

Continuing east on the trail, I passed the rock slide containing fossil shell impressions. The impressions are on a rock that broke apart in the slide. The slide is on the north side of the trail, about a quarter-mile from the western trailhead and 0.4-mile from the eastern trailhead.

After checking the eastern end of the trail, I retraced my steps and returned to the Lois Ewen Overlook. From there, I continued west on the Backbone Trail, visited the eastern summit of Saddle Peak, and then descended the Backbone Trail to its junction with the Stunt High Trail. The Stunt High Trail was used to complete the loop.

Other than the top of Saddle Peak, virtually none of the Topanga Lookout Ridge Loop was burned. The Backbone Trail crosses a huge preemptive firebreak on the north side of Saddle Peak several times, but the firefighters who constructed the firebreak took care to preserve the trail.

Hondo Canyon Out and Back Trail Run

Update October 25, 2025. The Fossil Ridge segment of the Backbone Trail APPEARS to have reopened. The orange tape across the trail at the top of the Hondo Canyon Trail and the CLOSED sign at its western end, near the Lois Ewen Overlook, have been removed. There is a stunning display of fire followers along the trail, including thousands of purple, large-flowered Phacelias.

When the updated restrictions for Topanga State Park were announced on March 21, 2025, one of the open trails that caught my eye was the Hondo Canyon segment of the Backbone Trail.

I’d run the Hondo Canyon Trail as part of point-to-point runs from Will Rogers and the Top of Reseda, but never as an out-and-back run from the trailhead on Old Topanga Road. Done this way, the segment is about 8 miles round-trip, with an elevation gain/loss of around 1700 feet.

When the Fossil Ridge/Saddle Peak segment of the Backbone Trail reopens, extending the route to Saddle Peak will add a bit more than three miles (round trip) to the route.

The turnout for the trailhead is on the southwest side of Old Topanga Canyon Road, about 0.4 mile from N. Topanga Canyon Blvd. Please note there is fire hydrant in the turnout that must remain clear and accessible.

The number of flowers and amount of plant growth along the trail were much more than would be expected in a “dry” Rain Year . Part of the reason, is that the previous two Rain Years were very wet. Another reason is the timing of the rain this Winter. The area received almost no rain until the end of January. Thanks to a wetter than normal February, and normal March, Los Angeles rainfall has been about normal since January 25. When it finally started to rain, it was at a time that was especially beneficial to the chaparral plants.

Here is an interactive, high resolution, 3-D terrain view of the Palisades burn area, zoomed in on the area of Hondo Canyon, Topanga Lookout, and Saddle Peak.

And here are a few photos and notes from the run.

More Ahmanson Mustard, Two Mariposa Lilies, and a Scraggy Road

Expansive mustard bloom at Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch)

This year’s expansive mustard bloom continues to draw hikers to the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch). Even though it’s an invasive weed and fire hazard, when it’s in widespread bloom it highlights the terrain as only mustard can.

Two of the three mariposa lilies that are found in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch) are blooming at the moment. The Catalina mariposa lily is especially prevalent along the first half-mile of East Las Virgenes Canyon fire road, near the Victory Trailhead. The yellow mariposa lily isn’t as easily found. It generally blooms after the Catalina mariposa lily, and occurs in widely scattered, small patches. Its yellow is so vivid as to be nearly incandescent. Even less common is Plummer’s mariposa lily, which typically blooms during the heat of summer.

Near the beginning of a run from the Victory Trailhead the other day, a passing mountain biker commented that the fire road in East Las Virgenes Canyon was “really chopped up.” It had rained a few days before, on the Saturday of a busy Spring weekend (April 26). Following the storm, the multitude of shoe imprints and clumps of mud hardened into an irregular, scraggy, concrete-like surface. The footing is the worst near the Victory Trailhead, but gradually gets better the farther west you go on East Las Virgenes Canyon fire road.

Simi Valley and Boney Mountain from the Chumash Trail

It rained yesterday, and today, the unsettled weather produced cloud-enhanced views of the Simi Valley and Boney Mountain from the Chumash Trail.

In the title photo, beyond the foothills of Simi Valley, is Boney Mountain. More than just a peak, Boney Mountain is a prominent volcanic massif at the western end of the Santa Monica Mountains.

In the photo, Sandstone Peak (3116′) — the highest peak in the Santa Monica Mountains — is on the left side of the massif, and Tri Peaks (3040′) is on the right. (Elevations are from PeaKBagger.com.)

The views from the Chumash Trail underscored the season, as did the Spring wildflowers. Like many other low-elevation areas of Southern California, a forest of black mustard covered the first few hundred yards of the trail.

Farther along the trail, bright yellow patches of bush sunflower amplified the scattered patches of sun, and yellow pincushion and golden yarrow added dabs of color to the chaparral.

Several species of Ceanothus are found along the trail. Hairy-leaved Ceanothus was in bloom. It is one of two local Ceanothus species that are 3-veined from the base but the only one with finely serrated leaves.

Notable for its beauty and dangerous character, this poisonous Fremont’s star lily was found about halfway up the trail.

Before you know it, the green hills of Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch) will have turned brown, and many of the early Spring wildflowers blooming along the area’s trails will be just a memory.

At the moment, all of the wildflowers mentioned in my previous post can still be found, but the earliest bloomers — such as goldfields  — are  gradually going away.

Some additional wildflowers that may currently be seen along Ahmanson Ranch trails include: Catalina mariposa lily, blue Dicks, monkey flower, fiddleneck, miniature lupine, and arroyo lupine.

Invasive mustard has become very prevalent, not only in the Kenneth Fire burn area, but throughout Upper Las Virgenes Canyon Open Space Preserve. It is picturesque when blooming, but fields and slopes covered in mustard increase the fire hazard when the stalks and leaves dry out under the hot summer sun.
