The 17.5-mile Trailer Canyon – Santa Ynez Canyon Trail – Trippet Ranch Loop is a longer version of the venerable Trippet Ranch loop from the Top of Reseda. It might also be called the Three Vistas Loop because it visits three high points in Topanga State Park with 360-degree, panoramic views.

The run starts and ends the same as the Trippet Ranch Loop. After running up to the Hub on Fire Road #30, instead of continuing straight on Eagle Springs Fire Road, this route turns left on Temescal Ridge Fire Road. The fire road is followed up to where the Backbone Trail single-track forks left off the road. The Backbone Trail is followed a tenth of a mile east, where a path leads up and left to the top of Temescal Peak.

The view from this little peak is superb. On a day with good visibility, the view can extend beyond Mt. Baldy to San Gorgonio Mountain and San Jacinto Peak. The next overlook on this route, Temescal Lookout, is about a half-mile (as the crow flies) to the south. The third overlook, Eagle Rock, is about a mile to the west.

From Temescal Peak, the route returns to Temescal Ridge Fire Road. I usually follow the use-trail back down and across the Backbone Trail and then continue on the use-trail to the fire road.

The next stop, Temescal Lookout, is about a mile from the top of Temescal Peak and just off Temescal Ridge Fire Road. When doing this loop, I run up a dirt access road on the north side of the lookout and then descend a use trail on the south side. Once the site of a fire lookout, it also has an excellent view. This photo of Downtown and San Jacinto Peak was taken from the viewpoint.

Once back on Temescal Ridge Fire Road and headed south, it’s less than a half-mile to the turn-off down Trailer Canyon Fire Road and then another 2.3 miles down to Michael Lane in Pacific Palisades. On the way down, there are good views of where the loop is headed next — Santa Ynez Canyon. A large part of Santa Ynez Canyon was burned in the May 2021 Palisades Fire.

After turning right (west) on Michael Lane, the street is followed around and down to Vereda de la Montura. A right turn here leads to the Santa Ynez Canyon Trailhead in about a quarter-mile. This is where some route-finding fun begins.

Heavy rains in December 2021 washed out sections of the Santa Ynez Canyon Trail. During the 2022-2023 rain season, the trail took it on the chin again. The good news is the trail sees a lot of use and the washed-out sections are becoming reestablished. There was still a little running water in the creek. Part way up the canyon, I was surprised to find pennyroyal blooming along the trail.

A bit more than a mile from the trailhead, the Santa Ynez Canyon Trail climbs out of the bottom of the canyon and up onto a broad ridge. Another mile of uphill, and it tops out at Eagle Springs Fire Road. After turning left, it’s less than a half-mile down to the Trippet Ranch parking lot.

The previous weekend I’d done the Trippet Ranch Loop, so knew what the expect on the remainder of the run. Other than being a little overgrown, the Musch Trail was in reasonable shape. There were still some late-season blooms of showy penstemon, yellow monkeyflower, and white snapdragon along the trail. This time of year, the round pincushions of buckwheat are common. Water was available at the start of the Musch Trail and at Musch Camp.

Reaching the top of the Musch Trail, high clouds kept the temperature comfortable as I worked up Eagle Rock Fire Road. At the turn-off to climb Eagle Rock, digger bees had established a temporary colony on the fire road. In my experience, these bees are not aggressive, BUT many sources — such as this news item from ISU Extension and Outreach — say the female bees can sting.

Eagle Rock is the third viewpoint on the loop, and the most popular. The massive rock formation overlooks Santa Ynez Canyon and has an airy, 360-degree view. On a clear day, Santa Monica Bay, Palos Verdes Peninsula, and Catalina can be seen to the south. On weekends, it’s rare to find the top empty. The summit had just been vacated as I climbed up and was reoccupied by another hiker as I walked down.

Returning to Eagle Rock Fire Road, I turned right and continued northeast a tenth of a mile to the top of the Garapito Trail.

A little more than three miles long, the Garapito Trail is one of my favorite trails in the Santa Monica Mountains. Several sections of the trail are overgrown at the moment. At one point, not too far from Fire Road #30, it was necessary to bushwhack through a dense patch of six-foot-tall giant rye grass.

Two lilies listed on the CNPS Inventory of Rare and Endangered Plants of California were blooming along the Garapito Trail — Plummer’s mariposa lily and Humboldt lily. Both plants have a Rare Plant Rank of 4.2, which indicates they are of limited distribution and moderately threatened in California. Thanks to our very wet rain season, the eye-catching red of scarlet larkspur was unusually prevalent along the trail.

The Garapito Trail ends at Fire Road #30. Normally the route would cross the fire road and follow the Bent Arrow Trail to dirt Mulholland, but the trail was damaged by rainy season storms and is still closed.

Turning left onto Fire Road #30, I retraced my steps from earlier in the morning and in a few minutes was back to the trailhead at the Top of Reseda (Marvin Braude Mulholland Gateway Park).

Ahmanson Ranch Hot Seat

It was a little past 3:00 in the afternoon when I passed this straight-backed wooden chair along an Ahmanson Ranch trail. The Tempe thermometer clipped to my pack read over 100 degrees.

It gets REALLY hot at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve). In the direct sun the temperature can be 10°F-15°F hotter than in the shade, and there is very little shade at Ahmanson. In-the-sun temperatures of 100°F or more are common in the Summer but can occur just about any time of the year.

There are two weather stations I use to get an idea of the weather conditions at Ahmanson Ranch — the Cheeseboro RAWS and Valley Circle Estates Weather Underground station. Weather station thermometers are usually shielded from the direct sun by a white, ventilated enclosure. The Cheeseboro RAWS includes a measurement of the “Fuel Temperature.” This is generally a better indication of the temperature experienced by a runner, hiker, or rider in the direct sun.

Update on July 29, 2023. Rounding the temperature to whole degrees, my West Hills weather station recorded a high of 100°F, or higher, for 15 consecutive days this July (7/13/23 to 7/27/23). The station is about three miles from the Victory Trailhead at Ahmanson Ranch.

It’s Mid-July And There Is Still Snow in Los Angeles County!

You might not see it from the Los Angeles side of the mountains, but there is still some snow on the higher, north-facing slopes of the San Gabriel Mountains.

During and after storms, snow-laden southerly winds dump their load on the backside of the crest, creating deep drifts, cornices, and compacted slabs of snow. This snow is often the last to melt, not only because it doesn’t face the sun, but because there is more of it.

This morning, I was doing an out-and-back from the Windy Gap Trailhead in the Crystal Lake Recreation Area to Mt. Baden-Powell. The Windy Gap Trail climbs 1730′ in 2.6 miles, joining the PCT at Windy Gap. From there the trail follows the spine of the San Gabriels past Mt. Hawkins, Throop Peak, and Mt. Burnham to Mt. Baden-Powell.

I usually do this run from Islip Saddle, but with Angeles Crest Highway (Highway 2) closed between Red Box and Vincent Gap, the Islip Saddle trailhead isn’t accessible.

Snow at about 9100′ on the west side of Mt. Baden-Powell.

Whether you start at Crystal Lake or Islip Saddle, the length of the run is about the same — a bit over 16 miles. The main difference is that the Windy Gap Trailhead is about 800′ lower in elevation. On the plus side, the Windy Gap Trail is very scenic; on the minus side, it faces south and can bake in the midday sun.

On today’s run, I encountered the first snowbanks at an elevation of 8870′, near the Dawson Saddle Trail junction. Out of curiosity, I tried to follow the trail and soon realized that was a mistake. I was more or less forced to skirt the downhill side of a lengthy and deep drift — it being too steep and icy to cross directly.

For the remainder of the run, I switched to the early season tactic of staying on the crest when the trail deviated onto shaded, north-facing slopes. These areas might have significant snow on the trail. This only happens in a few places, such as when the PCT works around Mt. Burnham. There is a use trail that ascends the west ridge of Mt. Burnham, and then returns to the PCT.

The conditions today are reminiscent of those found here in early July 2005. July 3rd of that year there was still snow on the summit of Baden-Powell, and there was deeper snow in the areas where there was snow today. We had a lot of storms this rain season, but in Rain Year 2004-2005 Downtown Los Angeles (USC) recorded about 9 inches more rain than during the 2022-2023 rain year!

Here is a short slideshow of some photos taken on the run. I’ve also included a few photos from the run to Baden-Powell in 2005 for comparison.

Escape to Mt. Pinos – An Alternative to Closed Angeles Crest Highway Trailheads

A long stretch of Angeles Crest Highway (Highway 2) between Red Box and Vincent Gap remains closed because of storm damage. According to a tweet from Caltrans District 7, it sounds like it may be closed through Summer. Some affected trailheads include Shortcut Saddle, Three Points, Mt. Waterman, Buckhorn, Mt. Williamson, and Islip Saddle.

Mt. Pinos is often overlooked as a trail running destination but offers several options for those that enjoy running or hiking in hilly terrain at higher altitude. Most of the runs at Mt. Pinos start at the Chula Vista Trailhead (8350′) at the end of Mt. Pinos Road.

Today, I was doing an out-and-back from the Chula Vista Trailhead to Mt. Abel/Cerro Noroeste (8280+’). The route includes short side trips to Mt. Pinos (8831′), Sawmill Mountain (8818′), Grouse Mountain (8582′), and Sheep Camp (8300′).

Including the side trips, the run/hike is about 15.5 miles long, with about 3700′ of gain/loss. Google Earth calculates the average elevation of the route to be 8434′. In comparison, the average elevation of the out and back from Islip Saddle to Mt. Baden-Powell is 8201′.

With triple-digit highs expected in some low-elevation areas, the temps on Mt. Pinos today were ever so pleasant — short-sleeves from the start and only a little toasty in a few exposed areas.

Despite the harsh Winter, there were only one or two small trees down on the Vincent Tumamait Trail, and those were inconsequential. As elsewhere in Southern California, the wildflowers along the trail were sensational. After nearly drying up last year, the spring at Sheep Camp was running at full flow.

If you are looking to run longer, add additional elevation gain, or explore the area, running to Lily Meadows and back from Sheep Camp extends the run to about 21 miles, with around 5400′ of elevation gain/loss.

Another option for a longer run is doing an out-and-back to Mesa Spring Camp, instead of Mt. Abel. Including a stop at Sheep Camp on the way back, this run is about 20.5 miles, with about 4800′ of gain/loss.

Lily Meadows and Mesa Springs see far less traffic than the Vincent Tumamait Trail. The trade-off is that both places are at lower elevation and can be 15-20 degrees warmer than Mt. Pinos.

Trying to Use AI to Solve a Malibu Creek State Park Plant Mystery

Terminal leaf cluster of Purple Clarkia (Clarkia purpurea), after it has flowered.

Recently, while doing the Bulldog Loop in Malibu Creek State Park, I noticed a peculiar plant about a half-mile up the Bulldog climb. The linear, red-tinged “petals” were unusual in the early morning light. I snapped a photo of it, planning to identify it later.

When I looked at the photo later that day, I couldn’t ID the plant. Hoping to get some hint about its identity, I tried various “AI-powered” searches and apps. This included Google Lens, Bing Visual Search, Pl@ntNet, iNaturalist Seek, PlantSnap, Flora Incognita, LeafSnap, and others. The most common matches were air plants such as Tillandsia ionantha and various species of paintbrush.

This wasn’t a huge surprise. The AI-based applications were having the same problems I was having — they were not “familiar” with this particular stage of the plant’s life cycle. They also were not keying on an important element of the image.

After a few days without any progress identifying the plant, I headed back to Malibu Creek State Park to take a closer look at the plant.

That turned out to be more challenging than expected. Even though I had the plant’s GPS coordinates, the time of day was different, with different lighting. The plant was also less colorful than before. I walked up and down a 30-yard stretch of Bulldog fire road several times before finally seeing it.

Once located, it didn’t take long to find examples of the plant at an earlier stage of development. In one case, with leaves on the stem and another with leaves and a flower. This helped solve the mystery.

It turned out the plant was one with which I was familiar — Purple Clarkia (Clarkia purpurea). The title photo is after the plant has flowered and all but a terminal cluster of leaves on the stem have wilted. The 8-grooved, elongated-football-shaped structures intermixed with the leaves are ovaries. These are distinctive. A human expert would have immediately zeroed in on these.

The flowers of Purple Clarkia are usually much larger than seen here. They are typically purple-pink with a wine-red spot on each of the four petals. However, the color of the flowers varies, and wine-colored flowers are not uncommon. The size of the flower also varies. Jepson mentions that the subspecies intergrade extensively.

Using the photo of the plant in flower, some of the AI-based apps identified the genus as Clarkia and/or the species as purpurea, or at least included Clarkia among their suggestions.

Searching For Another Blue Oak In Upper Las Virgenes Canyon Open Space Preserve

Blue oak-like leaves of an unusual oak in in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch).

After the Ahmanson Blue Oak in East Las Virgenes Canyon died this Winter, I started to search for another blue oak (Quercus douglasii) in Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson Ranch). Blue oaks are rare at the southern limit of their range, but I was hopeful that if there was one blue oak at Ahmanson, there might be another.

Valley oak leaves.

Typically, blue oak leaves are noticeably different than valley oak leaves. The Jepson eFlora describes the leaf margins of blue oak as being more or less entire, wavy, or more or less lobed. The leaves of the Ahmanson Blue Oak fit this description. Valley oak leaves are usually much more deeply lobed and readily identified.

Recently, while on a run, I noticed an unusual oak near the top of a service road on the western margin of Lasky Mesa. Its leaves are not deeply-lobed and are a bit more dusky than the usual valley oak leaf. But the tree doesn’t look quite the same as the Ahmanson Blue Oak. One difference is that the shape of the leaves is not as uniform as those of the Ahmanson Blue Oak. This might be due to the wet 2022-2023 rain season and the flourish of leaves that resulted. And, as with the Ahmanson Blue Oak, this oak was burned in the 2018 Woolsey Fire, and its trunk is partially hollow.

Based on its leaves, the “West Lasky Mesa Oak” could be a blue oak, blue oak hybrid, or valley oak hybrid. A 2002 study of a mixed stand of blue and valley oaks found that appearance can be misleading. When DNA tested, four of the five hybrid-appearing oaks in the study were not classified as hybrids. Of the four trees deemed most likely to be hybrids, only one oak was intermediate in appearance.

Although it seems unlikely this tree would have been overlooked, I could find no specific reference to the oak in the various studies and surveys done of Ahmanson Ranch. Please get in touch with me if you can provide additional information about this tree or how a DNA analysis can be arranged.
