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.

Was that thunder? I warily eyed the dark clouds over the mountains and pondered the situation.
I was about halfway to the top of the Chumash Trail and was planning to run along the crest to Rocky Peak. The run had started in short sleeves and sunshine, but it was pretty obvious that wasn’t going to last.
A cold upper-level low had brought badly needed rain to the area for the past two days. The low was moving off to the east, but there was still a chance of afternoon showers and maybe even a thunderstorm.
It was the “thunderstorm” part that I needed to pay attention to. I had enough gear to deal with a downpour and cooling temps, but electrical storms are no fun at all.
I decided to continue to the top of the Chumash Trail and reassess. As I worked up the trail, I pictured the counterclockwise circulation around the low, and how convective cells develop over the mountains and then dissipate as they drift south. The concern was that the cells don’t always dissipate.
It looked like things weren’t getting any better at the top of the Chumash Trail, but it wasn’t worse either. I hadn’t heard any thunder for a while, and most of the activity seemed to be a few miles to the west and east. Having been starved of stormy weather for much of the rain season, I turned right on Rocky Peak Road and headed south toward Rocky Peak.
The run from the Chumash Trailhead to Rocky Peak is a challenging mix of technical single-track trail and hilly fire road. There are wide-ranging views of Simi Valley & Simi Hills, the San Fernando Valley, Santa Monica Mountains, Ventura County mountains, and San Gabriel Mountains. On a clear day, the view can extend to the Channel Islands, Saddleback, and San Jacinto Peak.
The actual turnaround point for a run to “Rocky Peak” varies. Some like to turnaround at the high point of Rocky Peak Road that is near Rocky Peak. Most of the time, I turnaround at a viewpoint that is at the end of a spur trail that branches off from the high point of Rocky Peak Road. From time to time, it’s fun to hike over to Rocky Peak and scramble to the top. That’s a bit more involved and requires some route-finding.
I felt the first raindrops as I reached the high point on Rocky Peak Road and turned onto the spur trail that leads to the overlook. There was some increased development to the east, but it looked like there would be enough time to get over to Rocky Peak, take a couple of pics, and then head back.
I felt a little exposed on top of Rocky Peak. I hadn’t heard any thunder for the past hour, but a cell to the east was spouting heavy rain over the San Fernando Valley, which meant there was probably enough development to produce lightning. I took the title photo and a couple of others and hurriedly descended from the peak.
Back on Rock Peak Road, the sprinkles increased, and the showers became more steady as I ran north toward the Chumash Trail. Under the dark clouds, a raven perched on a large pinnacle cawed incessantly, either enjoying the rain or complaining about it. In the distance, a siren wailed down in the valley. It was cold, and I was very glad to have an extra shirt, sleeves, gloves and a light rain shell.
As I began the descent of the Chumash Trail, the sun briefly broke through the clouds, reflecting brightly on the wet sandstone rocks. I breathed deeply, relishing the smell of the cleansed air and wet chaparral, and continued down the trail.
Here’s an interactive 3D terrain view of my GPS track. Over the run, the temperature sensor on my pack recorded a drop of about 30 degrees — from around 70°F at the start of the run to about 40°F when the showers began! Here’s what a NOAA Radar Mosaic looked like at the start of the run and when I was on Rocky Peak.

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 unique view of Malibu Creek State Park.
I was running west on the Deer leg Trail, in the Reagan ranch area, when I stumbled onto the Lake Vista Trail. What’s this? I usually run the Deer Leg Trail in the opposite direction, and for some reason had not previously noticed this trail. 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 various small canyons. About 0.7 mile from the Deer Leg Trail junction, the Lake Vista Trail topped out at a very pretty overlook of Malibu Lake. My watch showed the mileage to the overlook from the Cistern Trailhead was about 2 miles.
From the overlook an unofficial “use” trail works back east along a broad ridge to the top of a butte that has a unique view 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.
