Bulldog Loop Plus the Phantom Loop

The Bulldog Loop, without any extras, is a little over 14 miles long, with an elevation gain of about 2700′.

While doing the Phantom Loop last week, I was reminded that a good way to extend the Bulldog Loop is to combine it with the Phantom Loop. This produces a run of about 19 miles, with an elevation gain of around 3650′.

This weekend I was looking to do something a little longer. With the National Forests in Southern California still closed, the usual high country options weren’t available. The temperature forecast looked warm, but not crazy hot, so it was a good day to do this run.

The Cistern/Phantom Trailhead on Mulholland Highway is a convenient place to start and end the loop. Later in the run, water is usually available from a faucet and fountains adjacent to the restrooms at the main MCSP parking lot. If doing the loop counterclockwise from the Cistern Trailhead, the restrooms and water are about 14 miles into the run.

The main attraction is still the Bulldog climb. From Crags Road to Castro Mtwy, the Bulldog Mtwy gains about 1730′ over about 3.4 miles. From the MCSP parking lot to the high point on the Phantom Trail, the route gains a bit more than 1000′ over 4.7 miles.

Here’s an interactive view of the merged 19 mile loop. A longer variation continues on the Grasslands Trail to De Anza Park and returns to Liberty Canyon on the Talepop Trail.

Redwoods, Raptors, and the Phantom Loop

It was a chilly 45°F as I crossed algae-covered Malibu Creek on a foot-worn log. Following a brutally hot Summer with temps in the West San Fernando Valley reaching 121°F, the chill of the cold air felt especially good.

The plan was to do the Phantom Loop, but first, I was going to run over to the Forest Trail. The side trip was not only to check on the coast redwoods along the trail but to enjoy the calm beauty of the area. To say 2020 has been unsettling is like saying a rattlesnake bite is a little annoying — and the year isn’t over yet.

After crossing the creek, I stopped to photograph the redwood near the junction of the Forest Trail and Crags Road. The sun had just risen, and behind the tree, orange-tinted sunlight illuminated the rocky ridge above the M*A*S*H site.

Continuing along the Forest Trail toward Century Lake, I counted four healthy-appearing redwoods and two struggling trees. Redwoods sometimes grow in a group of two or mote trees, and these were counted as a single “tree.” Near the end of the trail is a naturally-germinated redwood that has grown to about 5.5 inches in diameter. Remarkably, this young tree survived the 2011-2015 drought and the 2018 Woolsey Fire, and appears healthy!

I had just finished photographing the young tree when a Cooper’s or Sharp-shinned Hawk flew from a nearby oak and through the trees along the trail. It landed on the limb of an oak ahead of me but was in deep shade. In a much-enlarged image, the bird looks like a Sharp-shinned Hawk, but distinguishing the two species can be challenging.

A few yards down the trail, a much larger raptor — a Red-tailed hawk — was perched at the top of the tallest redwood. The huge bird had its wings pulled back to expose more of its body to the warming sun. It looked like a giant penguin sitting atop a tree. As I approached, it began to preen its feathers, comfortable with its lofty position.

With a sigh, I left the Forest Trail behind and returned to Malibu Creek. This time I crossed the creek on a plank near the washed-out bridge. This was a more direct route than the fallen tree upstream but only worked because the creek was low. At the crossing, a passing runner asked if he was on the Bulldog Loop. I assured him he was and was a little envious that he was getting to experience that excellent run for the first time.

As usual, Crags Road and the High Road were busy thoroughfares. The easy running under the sprawling coast live oaks was pleasant, and the morning view of Malibu Creek and Goat Buttes outstanding.

In a few minutes, I’d reached Mulholland Highway and then followed the Grasslands Trail to the Liberty Canyon Trail. From Liberty Canyon, the Phantom Trail gains about 750′ in elevation over about 1.5 miles to a high point and ridgeline with excellent views of Saddleback Peak, Las Virgenes Canyon, Brents Mountain, Goat Buttes, Castro Peak, Ladyface, and Boney Mountain.

The air quality this morning hadn’t been too bad. From up on the ridge, I could see there was far less smoke to the west of Las Virgenes Canyon than to the east. Yesterday, I’d done a run in the eastern Santa Monica Mountains and had to cut the run short because of smoke. That wasn’t a problem today, and the run had been a good one.

Trees, Bees, and a Washed-Out Footbridge on the Bulldog Loop in Malibu Creek State Park

With the reopening of trails in the Santa Monica Mountains, my list of “must do” trails is impossibly long. Today, I headed over to Malibu Creek State Park to do a variation of the popular Bulldog Loop, and catch-up on what was happening in the Park as it recovers from the Woolsey Fire.

The route I was running starts at the Cistern Trail trailhead on Mulholland and descends to Crags Road using the Lookout and Cage Creek Trails. After a side trip on the Forest Trail to see the coast redwoods, it continues counterclockwise around the regular Bulldog Loop. Here’s an interactive, 3D view of the approximately 17-mile variation of the Bulldog Loop.

Crossing Malibu Creek

As I ran along Crags Road toward the M*A*S*H site, I wondered how much water would be in Malibu Creek, and if the fallen tree used to cross the creek would still be there.

Washed-out footbridge on Malibu Creek

Since February 2019, hikers, runners, and riders doing the Bulldog Loop or headed to the M*A*S*H site have had to either get their feet wet or use a fallen tree to cross Malibu Creek. The concrete slab bridge is still there, but the stream now flows around the bridge, rendering it useless.

The bridge survived a canyon-wide flood in mid-February 2017. But two years later, and just 11 weeks after the Woolsey Fire, sediment-laden runoff from burned hillsides clogged the drainage pipes embedded in the bridge’s concrete slab. With nowhere to go, the stream simply circumvented the structure.

Nearly to the bridge, I turned right off of Crags Road and followed the well-trodden path along the creek for about 70 yards. The downed tree had not washed away. Not wanting to take an early morning bath, I carefully worked across the logs and limbs and then rejoined the Crags Road Trail, near a coast redwood.

Checking on the Malibu Creek State Park Redwoods

Whenever I do the Bulldog Loop, I usually stop by the Forest Trail and see how the 100+ year-old coast redwoods are doing. Several of the 16 or so redwoods were killed by the 2011-2015 drought, and virtually all the trees were scorched in the Woolsey fire.

I’d last checked on the redwoods at Christmas and had been encouraged by the condition of the remaining trees. In Los Angeles, three of the past four rain years have recorded average or above-average rainfall. This seems to have really helped the surviving redwoods.

There are five or six trees that are doing well. They’ve added a lot of new foliage and look healthy. I was excited to see that a young, naturally-germinated redwood was thriving. It was burned in the Woolsey Fire and lost most of its foliage.

Leaving the redwoods behind, I continued toward the M*A*S*H site and then up the Bulldog climb.

Coast Live Oak Recovery

Live oaks are amazingly resilient. Oaks, more or less as we know them, have been around for millions of years. According to Cal Poly’s PolyLand web site, 25 myr-old fossils of coast live oak have been found in the Pacific Northwest. This suggests an exceptionally adaptable species.

As I worked up the Bulldog fire road, I marveled at the number of live oaks sprouting new foliage on their burned trunks and limbs. On Mesa Peak Mtwy fire road, there is a grove of live oaks that used to provide welcome relief from the blazing-hot summer sun. On the crest of a ridge, the trees must have been fully-engulfed in fire when burned during Woolsey Fire. None the less, the trees are recovering. Compare this December 2018 photo of one of the larger live oaks, to what it looks like today. Incredible!

Digger Bees

Cruising along Mesa Peak Mtwy fire road, I took an auditory double-take. What the heck was all the buzzing around me? That’s when I realized the loud, resonate buzz was from thousands and thousands of bees. I’d just run into a huge aggregation of digger bees.

I’ve encountered them before. Even though the males (reportedly) don’t have a stinger and the females (reportedly) aren’t usually aggressive, it was a little unnerving walking through so many active bees. Here’s a video snapshot of the bees.

Digger bees are not social in the same way as honeybees. Female digger bees build their individual brood cells in a communal area to efficiently reproduce. According to behavioral ecologist John Alcock, the males emerge slightly before the females and then fly low over the area, searching for females that are about to emerge. Using their antennae, the males can find the females in a burrow, before they emerge, gaining a competitive edge. For more info, see the article Desert Diggers, in Arizona State University School of Life Sciences’ Ask A Biologist web site.

Splendid Mariposa and Other Wildflowers

At first I ran past it. I was descending the Tapia Spur Trail and nearly to the gravel parking lot in Malibu Creek State Park when a flash of purple caught my eye. My thought was that it was a solitary farewell-to-spring (Clarkia). But something didn’t seem right, and it would be unusual to see just one farewell-to-spring. So I went back to take a look, and it turned out to be a splendid mariposa lily (Calochortus splendens). Although it is common in areas south of Los Angeles, it is the first I have photographed in the Santa Monica Mountains. This one was not quite so splendid as it might have been since a beetle had been feasting on its petals.

Here are a few other flowers seen along the way:

Malibu Canyon to Saddle Peak, Topanga Lookout, Calabasas Peak, and the Secret Trail

Corpse Wall and other rock formations along the Backbone Trail near Saddle Peak.

The range of temperatures had been remarkable. At the Secret Trail trailhead in Calabasas, where I left my car, it had been a balmy 60 degrees. Near the start of my run from the Tapia Trailhead in Malibu Canyon, it had been a very chilly 32 °F. Near the end of the run, the temp topped out at 79 °F. That’s SoCal Winter running!

On the way to Saddle Peak, I was surprised to see how wet it was on some sections of the Backbone Trail. There has been very little rain this January, but marine layer dew, the trail’s north-facing aspect, the low sun angle, the canopy of bays and oaks, and relatively cool temps have kept the trail damp. In places it looked like it had just rained yesterday.

Because there’s about 1000′ less elevation gain, I usually do this run in the opposite direction, starting on the Secret Trail and ending at Tapia. This is the route described in the venerable guidebook, 50 Trail Runs in Southern California. But I’d run it in that direction a bunch of times — so here I was, chugging up the Backbone Trail, nearing the end of a 2600′, seven-mile climb from Tapia to Saddle Peak.

The area around Saddle Peak is yet another spectacular section of the Backbone Trail. (There are so many!) Just west of the peak, the trail winds through a narrow passage with massive sandstone rocks on either side. As the trail levels out, there is a short spur trail to the peak’s antennae-infested summit.

Even if a little obstructed, views from the top extend to Catalina, Boney Mountain, Mt. Pinos, and Mt. Baldy. Sometimes San Gorgonio Mountain and San Jacinto Peak can be seen beyond Mt. Baldy. The round trip to the summit of Saddle Peak adds about 0.8 mile. The eastern summit is slightly lower, but no antennae obstruct the view.

Getting to Saddle Peak from the Tapia trailhead is relatively straightforward, if a bit strenuous. Getting to Calabasas Peak and the Secret Trail from Saddle Peak is not as simple.

The “normal” way to get from Saddle Peak to Calabasas Peak would be to run back down the Backbone Trail to the Stunt High Trail and then follow that trail to the parking area on Stunt Road. Calabasas Peak Mtwy is across the highway and slightly downhill (west) of the parking area and leads to Calabasas Peak and the Secret Trail.

If doing the regular route, note that the Stunt High Trail crosses Stunt Road twice on the way down. In each case turn right and follow the road east about 100 yards to pick up the trail on the other side of the road. There are also various side trails to avoid.

I had been planning to do the regular route, but as I was returning to the Backbone Trail from Saddle Peak, it occurred to me there was a way to avoid backtracking. Instead of turning left on the Backbone Trail and descending to the Stunt High Trail, I turned right and continued east, past the water tank, to the Lois Ewen Overlook. From there, I ran over to the Topanga Lookout and then scrambled down Topanga Lookout Ridge to Calabasas Peak Mtwy.

This option is more adventurous, but requires good route-finding skills and being comfortable clambering down a rocky ridge. This 3D Cesium interactive view shows a GPS track of my route. The yellow track is today’s route. The red track is the usual route between the Backbone Trail and Calabasas Peak Mtwy. The view can be zoomed, tilted, rotated and panned. Placemark and track locations are approximate and subject to errors.

Scrambling down the ridge put me at “The Bench,” at the junction of Calabasas Peak Mtwy and Red Rock Road. This is a little more than a mile from Calabasas Peak. Once on Calabasas Peak, it was only about 0.6 mile to the top of the Secret Trail, and from there about 1.3 miles of mostly downhill running to the trailhead.

With about 4000′ of gain over 14 miles, it was a demanding route, with challenging route-finding and a fun scramble down a rocky ridge. Here are a few photos taken along the way.

Visualizing Trail Runs and Other KML Data Using Cesium 3D High Resolution Terrain

Cesium ion 3D view of San Gorgonio Mountain

Google discontinued its Google Earth API/Plugin in January 2017. That technology was used on PhotographyontheRun.com for 3D visualizations of trail runs, fire data, and other data.

I’ve been looking at alternatives since then, and have recently implemented an interactive viewer using the CesiumJS and Cesium ion components of the Cesium 3D Geospatial Platform. No browser add-on or plug-in is required. The viewer uses the Cesium World Terrain high-resolution global terrain tileset, with resolutions to 0.5 meter. The West Coast of the US is one of the areas covered by this resolution.

Following are example 3D visualizations of some of my recent runs. The views are interactive and can be zoomed, tilted, rotated and panned. Click/tap the “?” in the upper right corner for help manipulating the scene. Mileages and elevation gains/losses are approximate.

California Fuchsia Along East Las Virgenes Canyon Road

If the wildflower is red, the season is Fall, and you are in Southern California, the flower is probably California fuchsia. You might also find there is a hummingbird feeding on the “hummingbird trumpets,” or hovering nearby, watching over its flowers.

As a result of the wet 2018-19 rain season, and somewhat cooler than normal summer, California fuchsia is especially abundant this Fall, with some exceptional displays along local trails.

I’ve added California fuchsia, and a few other flowers that are blooming this Fall, to my Weekday Wildflowers slideshow. These are wildflowers photographed this year on weekday runs from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve.
