Will Rogers – Rivas Canyon – Temescal Canyon Trail Run

The previous weekend I’d done an out and back run from the “Top of Reseda” to the Oak Tree on the Rogers Road segment of the Backbone Trail. It’s an enjoyable run I could do on one bottle of water and get back by mid-morning. Including Temescal Peak, the run was about 14 miles roundtrip, with about 1800′ of elevation gain/loss.

This weekend, I hadn’t expected to be back on the Backbone Trail and headed for the Oak Tree again, but last weekend’s run reminded me that I hadn’t done the Will Rogers – Rivas Canyon – Temescal Canyon/Ridge loop in a couple of years.

The 20+ mile loop is an outstanding trail run that is both challenging and scenic. Done clockwise from the Top of Reseda, the run down Rogers Road is as enjoyable as the climb out of Temescal Canyon is difficult. On paper, the elevation gain/loss is around 3400′, but for me the run is usually a bit more strenuous than that stat would suggest.

On the way out I usually do a short side trip to Temescal Peak, and on the way back a short detour to Temescal Lookout. With good visibility, both points have extensive, 360-degree views. Temescal Peak can be accessed from the Backbone Trail about 0.1 mile east of Temescal Ridge Fire Road via a use trail. Temescal Lookout is just off the Temescal Ridge Fire Road, about 0.5 mile north of the Trailer Canyon/Temescal Ridge Fire Road junction.

On a clear day, there is a long list of places and peaks visible along the route. Among them are Century City, Downtown, Santa Monica Bay, Palos Verdes, Catalina, Boney Mountain, Hines Peak, San Gabriel Mountains, Mt. Baldy, Santiago Peak, and sometimes San Gorgonio Mountain and San Jacinto Peak.

Water is usually available at Will Rogers State Historic Park at the restrooms adjacent to the main parking lot and polo field. I’ve also topped off my water at the Temescal Canyon trailhead. The Rivas Canyon Trail is used to connect Will Rogers SHP to Temescal Canyon.

Not So Busy Sandstone Peak

With the closure of Los Padres, Angeles, San Bernardino, and Cleveland National Forests until Thursday, I did not expect to find the summit of the highest peak in the Santa Monica Mountains empty. Even if it was by happenstance, I’ve rarely found the summit of Sandstone unoccupied on a Saturday or Sunday morning.

Like last weekend’s run, this morning’s trail run started at the Wendy Drive Trailhead on Potrero Road in Newbury Park. But today’s route had a lot more elevation gain, and some steep scrambling up the rocks of Boney Mountain’s Western Ridge. It’s an adventurous way to do Boney Mountain, Tri Peaks, and Sandstone Peak, and get in some excellent running on a very scenic stretch of the Backbone Trail.

Overall, the route was in the best shape I’ve seen since the 2018 Woolsey Fire. The path that works up the north side of Tri Peaks and around the east side of its summit blocks was relatively clear. Following trailwork by the Santa Monica Mountains Trails Council, the Chamberlain Trail segment of the Backbone Trail was once again an enjoyable downhill run.

Here’s an interactive, 3D terrain view of a GPS trace of my usual route (yellow) to Sandstone Peak from Wendy Drive via Boney Mountain’s Western Ridge, and return via Big Sycamore Canyon. A GPS track of the Cabin trail is also shown. Variations of the route include doing the Mishe Mokwa loop after climbing Sandstone Peak; and returning to Sycamore Canyon via Serrano Valley/Canyon instead of Blue Canyon.

Fogbow Near the Top of Hell Hill in Pt. Mugu State Park

Fogbow Near the Top of Hell Hill in Pt. Mugu State Park

Fogbows form opposite the sun in a manner similar to rainbows, except the water droplets that create a fogbow are much smaller than raindrops. Because a fog droplet is so small, the physics of the interaction is different. The result is often a diffuse, primarily white bow.

The photograph of the fogbow was taken Sunday morning on an out and back run from Wendy Drive to Mugu Peak. The sun was about 14 degrees above the horizon. More about fogbows and other atmospheric phenomena can be found on Les Cowley’s Atmospheric Optics website.

Hidden Pond – Old Boney Loop, Pt. Mugu State Park

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.

Chasing a Sunrise, Taking a Moonshot, Los Padres Snow, and a Dark Line in the Sky

Colorful sunrise in the eastern Santa Monica Mountains

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.
