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).

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.

Red Box – Bear Canyon – Switzer’s Loop – Memorial Day Weekend 2023

The Red Box – Bear Canyon – Switzer’s Loop trail run is a favorite I’ve enjoyed doing for many years. Part of its attraction is the isolated, backcountry feel of Bear Canyon, particularly between Tom Sloane Saddle and Bear Canyon Trail Camp. It’s worth spending a few minutes at the old cabin site in the upper canyon to contemplate a lifestyle from an earlier century.

The descent of Bear Canyon is always adventurous in some way. Based on what I’d been seeing on other trails this year, I’d expected upper Bear Canyon to be a mess. I had braced myself for downed trees, washouts, and overgrown, hard-to-follow sections of trail.

But just a few minutes below Tom Sloane Saddle, a tree blocking the trail had been cleared, and the saw cuts were fresh! As I worked down the trail, I was excited to find more trailwork had been done. Branches or trees that had fallen across the trail had been cut. Some overgrown sections of trail had been trimmed. One washed-out section of trail looked like it had just been repaired. Someone had even trimmed a little of the poison oak that is so common along the trail.

As I discovered when I encountered them lower in the canyon, the Bear Canyon Trail Crew had been hard at work, and they were working in the canyon again today!

The last time I was in Bear Canyon (April 2021), the creek had been nearly dry. This year there was plenty of water and plenty of stream crossings. Unlike several recent runs, I had my poles and was able to keep my shoes and socks mostly dry.

I had debated whether to do this loop on Memorial Day Weekend. It passes through Switzer’s Picnic Area, one of the most popular day-use areas in Angeles National Forest. Many visiting Switzer’s do the hike down the Gabrielino Trail to see Switzer Falls, and many of those continue down the Bear Canyon Trail to the area below the falls.

Today, the two-mile stretch from below the falls to Switzer’s was as busy as expected. One issue I hadn’t anticipated was that some stream crossings were backed up like the Hillary Step on Everest. Other than wading, there was usually only one “dry” route across the stream. At one busy crossing, a hiker — clutching a dog under each arm — deftly balanced across a sequence of slippery rocks and branches, keeping his and his charge’s feet dry.

Once past Switzer’s, things returned to normal. From Switzer’s, it’s about 4.5 miles up to Red Box, with an elevation gain of about 1350′. I had been on this section of the Gabrielino Trail about a month before and was curious to see if a mass of fallen trees blocking the trail had been removed.

The trees still needed to be cleared — Forest Service rules require a qualified sawyer to do that kind of work — BUT the remaining 2.5 miles of trail to Red Box were being trimmed and cleared by several dozen members of the Mt. Wilson Bicycling Association. I wondered why I wasn’t seeing any mountain bikers on the trail — they were all working on it!

Afternoon Run on the Forest and Lost Cabin Trails in Malibu Creek State Park

The seasonal bridge across Malibu Creek is back! No sketchy log to test your balance or thigh-deep water to wade through — just walk across.

This afternoon I’d returned to Malibu Creek State Park to check on the bridge, count the surviving coast redwoods on the Forest Trail, and see what was happening on the Lost Cabin Trail.

When running the Bulldog Loop a couple of weeks ago, I did a quick check of some of the redwoods on the Forest Trail but skipped the back half of the trail. Today, I crawled through the downed trees blocking the trail and checked the rest of the trees.

I counted seven surviving redwoods. Several of these are  multi-tree groups consisting of two or more trees. These family groups  were counted as one tree. One of the trees, and perhaps more, was naturally germinated. Most of the trees looked healthy, but appearances can be deceiving.

One redwood is just a few feet from the Crags Road Trail. It’s on the right side of the trail, just past the seasonal bridge, when going west on Crags Road toward the M*A*S*H site. The unique conifer is easy to spot among the other trees.

The start of the Lost Cabin Trail is on the left as you enter the M*A*S*H site going west on Crags Road. Like the Forest Trail, it is less used and isolated but has a character all its own. Today, the Lost Cabin Trail was a trove of brightly colored wildflowers.

Here are a few photos taken along the way.

Wonderful Wildflowers, a Seasonal Bridge, and a Cranky Rattlesnake on the Bulldog Loop

Update May 5, 2023. Did a run this afternoon in Malibu Creek State Park and the seasonal bridge across Malibu Creek on the Crags Road Trail is back in place!

As I approached the M*A*S*H site, I could see some people taking photos. I stopped to say hi, and without skipping a beat, one of them asked, “Did you wade across the creek?”

He was asking about the creek crossing where Crags Road crosses Malibu Creek upstream of Century Lake and east of the M*A*S*H site.

There’s a substantial log spanning the creek at the moment, and I wanted to answer that I danced across it with my eyes closed. But instead, I explained that I decided to wade — and for sure keep my phone dry — rather than take a chance of falling uncontrolled into three feet of water, ker-splash.

Speaking of which, this morning, I talked to a mountain biker who saw the bridge pulled off to the side of the creek before any flooding had occurred and thought it may have been hauled away. Good news! According to the Malibu Creek Docents, the bridge is seasonal and was designed to be portable. It was removed and stored before this Winter’s rain. It is expected to be reinstalled when the threat of flooding is over — which should be soon.

After crossing Malibu Creek and before continuing to the M*A*S*H site, I took a quick detour on the Forest Trail. Bordered by Century Lake on one side, and steep, rocky slopes on the other, the Forest Trail has a character all its own. It’s a wonderful place to observe, reflect, and enjoy nature. It’s also home to several coast redwoods. Unfortunately, less than half the trees originally growing along the trail survived the 2011-2015 drought. This morning, a redwood that died several years ago had fallen and was partially blocking the trail near its halfway point.

As has been the case in most of Southern California this Spring, the wildflowers on this run were spectacular. Canyon sunflower was particularly prevalent, with many thousands of the bright-yellow blossoms covering the hillsides burned in the 2018 Woolsey Fire.

Also exciting was my first rattlesnake encounter of 2023. I was running down Castro Peak Mtwy Fire Road from the Bulldog “T” when I saw something in the road that looked like a partially exposed root. As I neared, I could see it was a very dark — almost black — Southern Pacific Rattlesnake.

The snake was stretched out straight on the road, basking in the sun. As I approached, it did move, and it did not rattle. Usually, snakes in this state are pretty docile, and I can cautiously walk a few feet behind them. Yikes! This one was super-aggressive. In the blink of an eye, it turned and moved toward me, doubling back on itself. I jumped a mile! It coiled but still did not rattle! It must have recently emerged from its Winter hideaway.

Here are a few photos (primarily wildflowers) taken on the Bulldog Loop.
