As long as I was in the neighborhood, I also wanted to do the short side trip to Mt. Waterman’s summit and see how it fared in the Bobcat Fire. (I’d skipped that side trip on the most recent Three Points Loop run.)
My general impression of Bobcat Fire impacts in the Mt. Waterman – Twin Peaks area is of varying severity. In some areas nearly all the trees were killed, while in other the trees are virtually untouched. Perhaps the most common scenario is a mix of burned, partially burned, and unburned trees.
Overall, I was surprised to find that there were so few fallen trees on the Twin Peaks Trail. I think I had to step over one log, go around another, and a couple others had been cleared from the trail. The most serious obstacle was some Poodle-dog bush completely blocking the trail. Poodle-dog bush causes dermatitis in many people.
There was little damage from the heavy December storms. The elevation ranges from about 6540′ at the low point of the Twin Peaks Trail, up to 7761′ on Twin Peaks East, so much of the precipitation must have fallen as snow.
A couple of trees were burned on the perimeter of Twin Peaks East’s flat summit, but the tops of both Twin Peaks East and Mt. Waterman were pleasant places to be.
Most of the time, when I do a trail run in the San Gabriel Mountains, it starts from a trailhead along or near Highway 2 — Angeles Crest Highway.
There are many fine point-to-point and out-and-back runs along Hwy 2, but not very many loops. Of the handful of loops that are currently open and accessible, two start and end at Three Points.
One is the Three Points – Mt. Hillyer Loop and the other is the Three Points Loop around Mt. Waterman. The Three Points – Mt. Hillyer Loop was not affected by the Bobcat Fire and is described in this April 2021 post.
On the other hand, significant parts of the Three Points Loop around Mt. Waterman were burned in Bobcat Fire, and the trails that comprise the loop were closed until April of this year (2022).
A large area on Mt. Waterman was burned by both the Bobcat and Station Fires. This can be seen in this interactive , 3D terrain view the area. The Bobcat Fire is yellow and the Station Fire is red. Where they overlap near Mt. Waterman is orange.
The Three Points Loop is the loop I do most often in the San Gabriel Mountains. The basic loop, not including the side trip to the summit of Mt. Waterman, is about 20 miles long and has about 4000′ of gain/loss. The terrain and trails are varied and interesting, and Buckhorn Campground is conveniently placed near the halfway point of the course. Water is USUALLY — BUT NOT ALWAYS — available when the campground is open.
Doing the side trip to Mt. Waterman adds about 1.7 miles and 350′ of elevation gain. The side trip to Cooper Canyon Falls is even shorter — only about a quarter-mile.
Fire perimeters and burn severity maps don’t tell the whole the story, and I’ve been curious to see how the area was affected by the Bobcat Fire; how the Station Fire recovery is continuing; and how the area burned by both fires has fared.
Here is an interactive, 3D terrain view of the Three Points Loop. The map can be zoomed, tilted, rotated, and panned using the navigation control on the right.

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.
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.
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.
When I parked at Malibu & Piuma to do the Bulldog Loop on Sunday, I didn’t know that I was going to be swept up in a Bulldog Ultra training run.
I had just started up Bulldog Mtwy fire road when the first group of speedy runners swarmed past. The strenuous climb to the Castro Peak Mtwy gains about 1750 feet over 3.4 miles. Much of its infamy is due to the oven-like conditions typically experienced on the second loop during the Bulldog 50K.
This morning, the climb was a little warm in spots, but not bad. There was a good turnout for the training run and nearly everyone was enjoying the run.
On the way up I had an interesting conversation with a runner that had just done their first 100 miler and was going to pace someone in the AC100 this weekend.
Here’s an interactive, 3D terrain view of the Bulldog loop. The map can be zoomed, tilted, rotated, and panned. To change the view, use the control on the upper right side of the screen.

Good luck to all the runners doing Bulldog — especially those doing their first trail race or ultra!
The Angeles Crest 100 Mile Run has always been considered a challenging 100 miler. This year it’s going to be even more challenging. Because of trail closures related to the Bobcat Fire and subsequent heavy runoff, this year’s course will be from Wrightwood, out to Shortcut Saddle, and back.
One of the main reasons it will be more difficult is that the course will, on average, be at higher altitude. According to Google Earth, the average elevation of previous AC100 courses has been around 5100′-5300′. This year’s course averages nearly 6900′.
Another big difference is that in the last 25 miles there will be two tough climbs on the highest sections of the course — the climb from Islip Saddle to Baden-Powell, and the climb from Vincent Gap to Blue Ridge.
And, as if that wasn’t enough, most calculate that the cumulative elevation gain is greater on the 2022 course than previous courses. The estimated elevation gain on the AC100 website for this year’s course is 23,228′.
Because of the increased difficulty, cutoff times have been adjusted and the overall time to complete the course has been increased to 36 hours — from 5:00 a.m Saturday morning to 5 p.m. Sunday afternoon.
The elevation profile of the 2022 AC100 course (PDF) was created in SportTracks from the GPX file on the AC100 website. The profile uses elevations corrected with pkan’s Elevation Correction Plugin and 3DEP 1-meter Lidar-based DEMs and a conservative elevation data smoothing setting.
Placemark locations, mileages, and elevation gains and losses are approximate. See the AC100 website for much more information and details. For comparison, here is an elevation profile from the 2017 AC100. Note that the 2017 profile was created using a GPS track from a runner and calibrated using lower resolution (1/3 arc-second) DEMs.
The race starts on August 6, 2022 at 5:00 a.m. in Wrightwood, California. There is a button/link for Runner Live Tracking on the AC100 Home Page. If you are participating, have a great race!
