The Hidden Pond – Old Boney Loop is a variation of the XTERRA Boney Mountain Trail Run 21K course. The route is about a half-mile longer and has a couple hundred feet more of elevation gain, but all the key trails are the same. It starts/ends at the Wendy Drive & Potrero Road Trailhead.
Here is an interactive 3D terrain view of the Hidden Pond – Old Boney Loop and a few photos taken along the way.

This morning’s running plan morphed from doing a loop I’ve done many times, to exploring a trail I hadn’t done, and hiking along a ridge to the top of a butte with a sweeping view of Malibu Creek State Park.
My run started at the Cistern Trailhead on Mulholland Highway. After descending the Cistern Trail, I picked up the Lookout Trail and headed west to the top of the Cage Creek Trail and the start of the Yearling Trail. Continuing on the Yearling Trail, I turned left (south) up the Deer Leg Trail, and continued west on the enjoyable, up-and-down single track.
I usually run the Deer Leg trail in the opposite direction and was a little surprised when I happened upon the Lake Vista Trail. How had I managed to run past this trail junction so many times and not notice it? Any trail with “Vista” in the name is worth exploring, so there was little choice but to turn onto the trail and see where it led.
As it climbed toward an obvious ridgeline, the enjoyable single-track trail wound in and out of several small canyons. About 0.7 mile from the Deer Leg Trail junction, the Lake Vista Trail topped out at a very pretty overlook of Malibou Lake (not a typo). My watch showed the mileage to the overlook from the Cistern Trailhead was about 2 miles.
From the overlook an unofficial “use” trail worked back east along a broad ridge to the top of a prominent butte that has an unique exceptional of Malibu Creek, Century Lake and Goat Buttes. Because of the area’s volcanic origins, the use trail is rough and rocky in places, and the trail is not always obvious. It’s a little under a half-mile from the overlook to the summit of the butte. Even though it was Winter, I kept a wary eye and ear out for rattlesnakes.
Once back at the overlook, I made a loop of it by descending the Lake Vista Trail to the Reagan Ranch parking area, and then working back east on the Yearling and Lookout Trails to the Cistern Trail. Here’s an interactive, 3D terrain view of my GPS track of the run and hike.
I was running up Calabasas Peak Mtwy fire road trying to get a better view of the eastern sky, but the view in that direction was blocked by a steep hillside. The road turned to the northeast up ahead, and I hoped the best moments of a rapidly-evolving sunrise would not be lost.
A couple of breathless minutes later, I rounded a corner and was rewarded with an unobstructed view of a vivid, pink-red-orange mackerel sky. Focusing on the ridgeline near Topanga tower, I shot several sets of bracketed photos.
Excited by the sunrise, I continued up the fire road, scanning my surroundings for another photo. My eye settled on the gibbous moon. High in the sky, it’s bright face was subdued by a thin veil of pinkish-gray cloud. I’d previously experimented with handheld shots of the Moon using my running camera — a Lumix ZS100. Zooming to an equivalent focal length of about 250mm, I held my breath, steadied the camera the best I could, and took a few shots. Here’s one of the images — cropped and sharpened — with enough detail to see craters, maria, and some other lunar features.
At the bottom of Topanga Lookout Ridge there were several bigberry manzanita bushes covered with flowers. A hummingbird was up before sunrise, buzzing about the blossoms, busily drinking the precious nectar. Although it had rained a couple days before, this rain year there had been little rainfall, and a corresponding scarcity of early season wildflowers.
As I climbed higher on the ridge, the mountains northwest of Los Angeles came into view, white with snow from the recent storm. The snow-covered peaks are south of Mt. Pinos and Frazier Mountain, in the area of San Raphael Peak, McDonald Peak, Sewart Mountain and Snowy Peak.
Like snow on a mountain, there is a purity in the form and appearance of clouds. When a long, dark streak appeared across a layer of high clouds, it was hard to miss. In this case, the dark line appears to be the shadow of a contrail of a jet flying above the clouds. At the time LAX was reporting scattered clouds at 19,000′ and 23,000′, with a broken layer of clouds at 28,000′. Given the height of the clouds and orientation of the contrail, it may have been from a flight from San Diego to San Francisco.
Topping out on the ridge, I smiled when I saw the masked couple dancing on the Lookout, and continued west toward Saddle Peak.

As I neared the top of Topanga Lookout Ridge, I could hear music coming from the Lookout. It looked like there were people on top, but from my vantage point down on the ridge, it was hard to tell what was going on.
When I reached the isolated platform, I was surprised to find a couple dancing! Wearing masks, and with much of the San Fernando Valley as a backdrop, they had found a unique way to deal with the complications of the pandemic.

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.

Updated June 26, 2023. The spiral has been periodically removed and rebuilt over the years. Google Earth historical imagery shows that it was removed sometime between March 2021 and February 2022. As of June 25, 2023, it had not yet been rebuilt.
Instead of struggling to escape a tar pit, this “mammoth” seems to have been caught up in 25-30 million-year-old sandstone.
The beast can be seen along the Backbone Trail, east of the Corral Canyon Trailhead. When running/hiking/riding east from the trailhead, the trail climbs over two steep steps and up to gap in the rock. In the photo above, the gap is on the left and the mammoth figure is on the right. From the gap, the trail descends a rock corridor to Mesa Peak fire road.
A closer look at the mammoth reveals that it is pockmarked and there are rocks embedded in the sandstone. The embedded rocks are cobble from an ancient river and the pockmarks are where rounded rocks have fallen out of the eroding sandstone.
Stream cobble that has eroded out of sandstone formations in this area has been used to construct a spiral labyrinth on the north side of Mesa Peak Fire Road. The cobble was tumbled and smoothed by streams that drained a range much older than the Santa Monica Mountains.
The title photo is from this morning’s run of the Bulldog Loop.
