Another Triple-Digit Sunday
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.

Thirsty Mt. Pinos
A couple leaving the camp saw that I was trying to collect drips of water from the nearly dry spring. I told them I was OK, and had water in my pack — I was just using a makeshift cup to get a couple of mouthfuls of cool water from the slowly dripping spring.
I had stopped at Sheep Camp (8300′) in the Chumash Wilderness, in Los Padres National Forest. The day was warm and the spring at the camp is usually a refreshing stop on the way back to Mt. Pinos and the trailhead at the Chula Vista parking area. Earlier, I’d talked to a runner training for the Kodiak 100, and he’d mentioned that the spring was a key source of water for his dog.
In recent years water has sometimes been an issue at the Sheep Camp spring. In July 2018, six out of the past seven Rain Years had been dry, and the flow of the spring was just a trickle. But it had been enough to slowly refill my Camelbak (TM) and get me down to Lily Camp (6600′) and back. Not so today.
Even without the water, Sheep Camp is a pleasant and worthwhile detour. Old growth pines tower above and bright yellow sneezeweed and other flowers are sprinkled about the forest floor. In the Spring large patches of iris bloom in the damp areas.
Today, I was returning from Mt. Abel, after having done Mt. Pinos, Sawmill Mountain, and Grouse Mountain on the way to Mt. Abel from the Chula Vista parking area. Here is an elevation profile of the run/hike. The cumulative elevation gain on the 15.5 mile run is about 3700′.
The short side trips to the summits of Mt. Pinos and Sawmill require almost no extra effort, and the view from Sawmill — if it’s not too smoky or hazy — is wide-ranging. Getting to the twin summits of Grouse takes a bit more work, but it’s fun to follow the short use trail up the south summit and then to wander through the pines to the slightly taller north summit.
The descent that follows — down the use trail from Grouse and then down the Vincent Tumamait Trail to Puerto del Suelo, drops about 1000′ in elevation over 1.6 miles. This, of course, must be repaid on the way back!
When you reach the road at the end of the Vincent Tumamait Trail, you might remark, “But there’s no trail to Abel!” And you would be correct. It’s fairly straightforward to trek up through the forest from the road, though care is required due to the debris from forestry work in the area.
Here’s an interactive, 3D terrain view of the run/hike from Mt. Pinos to Mt. Abel, with side trips to Sawmill Mountain, Grouse Mountain and Sheep Camp. The map can be zoomed, tilted, rotated, and panned. To change the view, use the control on the upper right side of the screen. Track and placename locations are approximate and subject to errors. Poor weather, snow, ice, and other conditions may make this route unsuitable for this activity.

Revitalized Valley Oak at Ahmanson Ranch
Revitalized by December’s copious rainfall and temperatures in the mid-80s in February, this valley oak at Ahmanson Ranch has produced a lush crown of new leaves.
(Officially named Upper Las Virgenes Canyon Open Space Preserve, most users refer to the open space area as Ahmanson Ranch, or simply, Ahmanson.)
Clearing Skies at Ahmanson Ranch
The cumulus cloud towered overhead, its size accentuated by a lone oak on the skyline. An extraordinary series of December rainstorms were finally over. The year 2021 would end with Downtown Los Angeles (USC) having recorded the third highest amount of December rainfall on record.
I was running from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson) to Las Virgenes Canyon. With about 5 inches of rain in the area over the past two days, I was curious to see how upper Las Virgenes Creek was flowing.
Here are a few photos from the December 31st trail run and several other trail runs at Ahmanson over the past couple of wet weeks.
Running Between Storms on the Trippet Ranch Loop
Update January 4, 2022. Did the Garapito Trail again this weekend as part of a longer run through Santa Ynez Canyon. The debris from the fallen oak tree was much easier to get through this time. Some people coming down the trail after me had a small saw, and said they were planning to work on it.
Update December 31, 2021. It turns out that a lot more rain was on the way! Los Angeles recorded 9.46 inches of rain this month, making it the third wettest December on record, going back to 1877. This puts Los Angeles at 10.40 inches for the Rain Year to date, which is about 237% of the normal.
It had rained the past three days, including Christmas. Today was the 26th, and Downtown Los Angeles (USC) had recorded nearly 150% of the rainfall normally recorded in December. And more was on the way.
I clicked START on my Garmin as I passed the gate at the Top of Reseda. It was about twenty minutes before sunrise. The temperature was around 40 and the eastern sky was brightening with the advancing sun. As I worked up the initial trail to dirt Mulholland, thousands of lights twinkled across the San Fernando Valley.
The chaparral was soaked with overnight rain; and befitting the Holiday season, was ornamented with thousands of silvery water drops.
I took my usual route, turning off Mulholland onto Fire Road #30, and then following it to the Hub. From the Hub, Eagle Springs Fire Road led down to Eagle Springs, then beneath the sunlit face of Eagle Rock to Eagle Rock Fire Road and the top of the Musch Trail. In the Palisades Fire burn area there was some significant erosion along the fire road where the runoff wasn’t controlled.
I’d be doing the Musch Trail later in the run, but for now continued down Eagle Springs Fire Road toward Trippet Ranch.
Mud — slippery, cake-on-your-shoes mud — isn’t normally much of an issue until past the Musch Trail and on the steeper downhill that leads to the top of the Santa Ynez Trail and Trippet Ranch. Today there were some slippery spots, but it wasn’t too bad. Remarkably, I didn’t see anyone until I reached the Trippet Ranch parking lot.
My return route from Trippet Ranch was mostly on trails, beginning with the Musch Trail. There are usually a few muddy sections on the Musch Trail after a good rainstorm. Today, one wet, muddy section of trail was steaming in the morning sun. Once I was on the steep climb up to Eagle Rock Fire Road, most of the significant mud was left behind.
At the top of the Musch Trail, I turned left on Eagle Rock Fire Road and worked up past Eagle Rock and over to the top of the Garapito Trail. I run this trail often, and know it well. Winding down through decades-old chaparral, I became lost in thought, immersed in the outdoor experience, and enjoying every aspect of the trail.
That was why it was such a shock when, at the bottom of the mile and a half descent, the trail suddenly ended in a wall of brush.
That couldn’t be. Had I somehow turned onto a use trail? Nope, I was on the right trail.
That’s when I noticed the “brush” was the top branches of a large oak. The fallen tree had COMPLETELY blocked the trail. I took a quick look around for an alternate route and didn’t see anything obvious. Working through the mishmash of foliage and branches was a bit like bushwhacking through dense manzanita. With some effort, and some rock climbing moves, I eventually emerged on the other side of the mass. The fallen tree was part of an old, multi-trunked oak that has been collapsing over a period of weeks.
The remainder of the run was uneventful, but enjoyable. Continuing up the Garapito trail to Fire road #30, I crossed the fire road and picked up the Bent Arrow Trail. This connects to dirt Mulholland, which leads west to the Top of Reseda.
