Musch Meadow Frost

Frost along the Backbone Trail at Musch Meadow

As I approached Musch Camp, a scrub jay flew from a trailside faucet and into a nearby eucalyptus. There had been a little rain the day before, but the birds at the closed camp were still thirsty. Less than a quarter-inch of rain had fallen, and nearby creeks were still dry.

I was doing a run from the “Top of Reseda,” and on a warmer day would have topped off my water bottle at the camp. I stopped at the faucet and briefly turned on the spigot. Maybe that would make it easier for the jay.

Leaving the camp behind, I continued south on the Backbone Trail, across frost-covered Musch Meadow. Early morning sun had just reached the meadow, and water vapor from the melting frost steamed in the cold air.

In another mile I reached the Trippet Ranch trailhead, and then begin the six mile run back to the Valley. At several points on the run there had been wintry views of the local mountains. On the way back the best view of the snowy mountains was from the Hub, where Mt. Baldy could be seen gleaming white in the morning sun.

A Windy Run, Walk, Ride, for Wildlife Research

The Overlook Fire Road in Pt. Mugu State Park was nearly empty. I’d seen only two hikers between the top of the Fireline Trail and the top of the Wood Canyon Vista Trail. Maybe it was the wind. There had been 20-25 mph wind gusts much of the morning. Along the ridgelines, the gusts were even stronger.

Run, Walk, Ride 2020

I’d picked Pt. Mugu State Park to do a run in support of the Santa Monica Mountains Fund’s Run, Walk, Ride, for Wildlife Research. Many mountain lions have included Pt. Mugu State Park in their home range, including P-1, the patriarch of the mountain lions in the Santa Monica Mountains study.

According to the NPS website, the Santa Monica Mountains National Recreation Area is the world’s largest urban national park. Wildlife in the Park is affected by issues resulting from the proximity of urban and wild areas. Among the problems are poisoning from anticoagulant rodenticides, limited genetic diversity, and vehicular deaths. Only by studying Park wildlife can we better understand and manage these and other issues.

Because water is usually available at several spots in Sycamore Canyon, it’s a great place to do a self-supported ultra-length trail run.

So far, today’s run had taken me from Wendy Drive in Newbury Park to Serrano Valley via the Old Boney Trail. I’d circled past the old ranch in Serrano Valley and then descended the Serrano Canyon Trail to Sycamore Canyon. A short jog south in Sycamore Canyon put me at the bottom of the Fireline Trail, which I’d followed up to the Overlook fire road.

Next up was a scenic loop in La Jolla Valley. After that, I would work my way back to the Upper Sycamore Trail via Sycamore Canyon. From there, it would only be a few miles back to the Wendy Drive Trailhead.

The Santa Mountain Mountains Trails Council has been hard at work. Even though they can’t currently accept volunteer assistance, it looked like the Old Boney, Serrano Canyon, and Upper Sycamore Trails had been recently maintained.

Topanga Lookout From Topanga Ridge

Topanga Lookout From Topanga Ridge

This morning, did the Topanga Lookout Ridge loop, plus the twin summits of Saddle Peak.

Here’s what the Topanga Fire Lookout looked like in 1969.

For more info about the loop, see the posts: Topanga Lookout Loop, Plus Saddle Peak and Topanga Lookout Ridge Loop

The short service road at the top of Saddle Peak’s antennae-festooned west peak was closed when I did this run, but was open again on December 5, 2020.

Too Many Flowers on the Chamberlain Trail

After climbing the western ridge route on Boney Mountain and scrambling over Tri Peaks, I was trying to run down the Chamberlain segment of the Backbone Trail. Usually one of my favorite downhills, the trail was so glutted with the flower stalks of bleeding heart, it made running difficult. Here’s a video snapshot of one short section of trail.

During this second Spring following the Woolsey Fire, bleeding heart has become a predominant fire follower in the Boney Mountain Wilderness. Its rampant growth is reminiscent of the explosion of Poodle-dog bush in the San Gabriel Mountains the second Spring following the 2009 Station Fire.

Sticky snapdragon is another fire follower that has become especially prevalent this Spring. It is truly sticky, with rose-purple-colored flowers along a long stalk.

Other wildflowers seen along the way included Humboldt lily, yellow mariposa lily, Plummer’s mariposa lily, slender tarweed, and scarlet larkspur.

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

Looking along the crest of the Santa Monica Mountains from near the top of the Bulldog fire road.

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.

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.

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:
