Modelo Mustard

Mustard flowering in Cheeseboro Canyon reveals the underlying structure of a hill.

Mustard flowering in Cheeseboro Canyon reveals the underlying structure of a hill.

According to the Dibblee geologic map of the area, the strata are part of the Modelo Formation. And… the Modelo Trail passes directly over the top of the hill.

The photo was taken on a run from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve to the Cheeseboro Ridge Trail and back.

It was a chilly 45 degrees in the canyon, and I had already resigned myself to having to wade across Big Tujunga Creek. But I didn’t even get my shoes wet. The water level was low enough that the large rocks placed across the creek were high and dry.

It was a good start to what was to be an excellent run and hike. As I gained elevation, it was evident there had been recent work on the trail. Trimmings from the brush along the trail were still green, and in several spots the tread had been freshly manicured. The higher I climbed, the more work had been done. In a couple of places, substantial washouts had been repaired.

Last year, the trailwork ended abruptly about halfway up the trail. Not so this year. An impressive amount of work had been done to clear the trail of a tortuous mix of dead scrub oaks and thorny brush. Without having to crawl over, around, and through those snarls, my roundtrip time to the summit and back was a full hour faster than last year. Many thanks to whoever worked on the trail!

Although rainfall has been below normal this rain season, there were still some wildflowers blooming along the trail. Among them were bush poppy, chaparral currant, and hoary-leaved Ceanothus.

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.

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.

Chumash-Las Llajas Loop

Update of a post from December 30, 2006.

The Chumash-Las Llajas Loop is a scenic 9.3 mile trail run in the eastern Simi Valley. Run counterclockwise, it combines a  strenuous climb on a single-track trail and fire road with a fast-paced 4-mile downhill on a dirt road. The cumulative elevation gain/loss on the loop is about 1600′.

I like to do the loop starting at the Las Llajas Canyon trailhead on Evening Sky Drive. A short jog up Evening Sky Dr., then across a field, and you’re on your way up the Chumash Trail. From this point, it’s an approximately 1000′ climb over 2.7 miles of rocky trail to Rocky Peak fire road.

After turning left (north) on Rocky Peak fire road, a short downhill is followed by three-quarters of a mile of climbing to “Fossil Point.” A short detour off the main fire road leads to a cairn marking the high point. From here there is a panoramic view of Oat Mountain, San Fernando Valley, San Gabriel Mountains, Santa Monica Mountains, Simi Valley, Boney Mountain, Channel Islands, and Ventura Mountains.

Exposures of fossil shells are found near the high point. According to the area’s Dibblee geology map, these may have been deposited in shallow marine lagoons a couple million years ago.

From the high point, the loop continues north on Rocky Peak Road. At first, it descends steeply, then climbs to a hilltop with a few valley oaks. Partway up the hill, a roadcut reveals the long roots of the chamise plants on the hillside.

Following a short downhill, the road continues past a fallen valley oak killed by the 2011-2015 drought. There is a fork in the road here. The road connecting to Las Llajas Canyon goes up a short hill to an overlook of the canyon. From the top of the hill, there are more than 4 miles of downhill through the winding canyon. There used to be oil field equipment on the connector between Rocky Peak Rd. and Las Llajas Canyon, but it has been removed.

If the creek in the canyon is flowing, there are several places where the (usually) small stream crosses the road. In the Spring and early Summer, many species of wildflowers can be found in the canyon.

Some of the wildlife, and not-so-wild animals, I’ve encountered on the loop include rattlesnakes and other snakes, deer, longhorn cattle, roadrunners, and a kangaroo rat. Although others have seen mountain lions in the area, I’ve only photographed their tracks.

The loop ends with a short, steep climb up a paved road. At the top of the hill, turn left to return to the trailhead.

Here’s a 3D, interactive view of a GPS trace of my usual route. (It is also possible to start the loop at the Chumash Trail trailhead at the end of Flanagan Dr.)

Orange Sun Rising – A Boney Mountain Adventure Run

Smoky view from Boney Mountain's Western Ridge

To the east, the sun rose orange, cast that color by a thick pall of smoke. From the Satwiwa Loop Trail, the view of Boney Mountain were surprisingly clear. As the air pollution sensors in the area had indicated, the air quality appeared to be passable. I hoped it would stay that way for the remainder of the run.

With all the National Forests in California closed through at least September 21, and the smoke from wildfires affecting many areas, I’d been fortunate to find a place where I could get out and stretch my legs.

I was doing a route I had done many times before — a loop incorporating the Western Ridge of Boney Mountain and the Chamberlain segment of the Backbone Trail. I’d last done the loop in June and was curious to see the condition of the Chamberlain Trail and how recovery from the 2018 Woolsey Fire was progressing.

From the top of Peak 2935, it seemed the “smoke front” to the east was slowly creeping closer. The flat, orange light was eerie. Continuing to Tri Peaks, I decided to skip the side trip to Sandstone Peak and followed the west Tri Peaks trail directly to the top of the Chamberlain Trail.

Foot traffic on the Chamberlain Trail had opened it up a bit, but there were still thousands and thousands of stalks of bleeding heart along the trail. The condition of the trail improved somewhat below Chamberlain Rock.

When I’d done the route in June, I’d seen no one until just before the junction of the Chamberlain & Old Boney trails. In June it had been a group of hikers. This time it was another runner, and we exchanged notes about the routes we were doing. Below the junction, I was surprised to find that one of the seeps on the Old Boney Trail was still wet.

After getting some water at the Danielson Multi-Use Area, I continued up Sycamore Canyon, finishing the run on the Upper Sycamore Trail, Danielson Road, and the network of Satwiwa trails.

Here are a few photos taken along the way.
