Chumash Trail Mule Deer

Mule deer on the Chumash Trail in Simi Valley

I saw a flash of brown through the bushes on the trail ahead. I stopped as a deer emerged from a switchback. The doe was walking slowly up the trail with her mule-like ears turned back toward me. I said something like, “Where are you going?”

She turned toward me and stared quizzically. As I slowly pulled the phone from my pack, I continued to talk. Her expression was a mix of caution and curiosity. It was as if she couldn’t quite make up her mind what I was about.

This was peculiar behavior for a deer in this area. It wouldn’t be so strange if I was at Trippet Ranch. The deer there graze around the oaks and grasslands near the parking lot and are used to seeing people. But in decades of running the Chumash Trail, I’ve only occasionally seen deer, and they have always been skittish and quick to react.

This doe watched me as I slowly walked around the bend and toward her. I was reminded of a friend’s experience, when he was hit on the shoulder by a spooked deer. Not wanting to force a reaction, I stopped. The deer casually stepped off the trail and disappeared down the ravine.

Later, running down Las Llajas Canyon, I was startled by the sound of something large moving in the brush. This time I got only a fleeting glimpse, as the deer bounded uphill through the trees, rocks, and brush.

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 that was 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.)

This rain season’s on again, off again pattern has produced an exceptional selection of wildflowers.

Here is a slideshow of a some of the flowers blooming in and around Las Llajas, Chivo, and Tapo Canyons.
