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.)

Bulldog Loop Plus the Phantom Loop

The Bulldog Loop, without any extras, is a little over 14 miles long, with an elevation gain of about 2700′.

While doing the Phantom Loop last week, I was reminded that a good way to extend the Bulldog Loop is to combine it with the Phantom Loop. This produces a run of about 19 miles, with an elevation gain of around 3650′.

This weekend I was looking to do something a little longer. With the National Forests in Southern California still closed, the usual high country options weren’t available. The temperature forecast looked warm, but not crazy hot, so it was a good day to do this run.

The Cistern/Phantom Trailhead on Mulholland Highway is a convenient place to start and end the loop. Later in the run, water is usually available from a faucet and fountains adjacent to the restrooms at the main MCSP parking lot. If doing the loop counterclockwise from the Cistern Trailhead, the restrooms and water are about 14 miles into the run.

The main attraction is still the Bulldog climb. From Crags Road to Castro Mtwy, the Bulldog Mtwy gains about 1730′ over about 3.4 miles. From the MCSP parking lot to the high point on the Phantom Trail, the route gains a bit more than 1000′ over 4.7 miles.

Here’s an interactive view of the merged 19 mile loop. A longer variation continues on the Grasslands Trail to De Anza Park and returns to Liberty Canyon on the Talepop Trail.

Redwoods, Raptors, and the Phantom Loop

It was a chilly 45°F as I crossed algae-covered Malibu Creek on a foot-worn log. Following a brutally hot Summer with temps in the West San Fernando Valley reaching 121°F, the chill of the cold air felt especially good.

The plan was to do the Phantom Loop, but first, I was going to run over to the Forest Trail. The side trip was not only to check on the coast redwoods along the trail but to enjoy the calm beauty of the area. To say 2020 has been unsettling is like saying a rattlesnake bite is a little annoying — and the year isn’t over yet.

After crossing the creek, I stopped to photograph the redwood near the junction of the Forest Trail and Crags Road. The sun had just risen, and behind the tree, orange-tinted sunlight illuminated the rocky ridge above the M*A*S*H site.

Continuing along the Forest Trail toward Century Lake, I counted four healthy-appearing redwoods and two struggling trees. Redwoods sometimes grow in a group of two or mote trees, and these were counted as a single “tree.” Near the end of the trail is a naturally-germinated redwood that has grown to about 5.5 inches in diameter. Remarkably, this young tree survived the 2011-2015 drought and the 2018 Woolsey Fire, and appears healthy!

I had just finished photographing the young tree when a Cooper’s or Sharp-shinned Hawk flew from a nearby oak and through the trees along the trail. It landed on the limb of an oak ahead of me but was in deep shade. In a much-enlarged image, the bird looks like a Sharp-shinned Hawk, but distinguishing the two species can be challenging.

A few yards down the trail, a much larger raptor — a Red-tailed hawk — was perched at the top of the tallest redwood. The huge bird had its wings pulled back to expose more of its body to the warming sun. It looked like a giant penguin sitting atop a tree. As I approached, it began to preen its feathers, comfortable with its lofty position.

With a sigh, I left the Forest Trail behind and returned to Malibu Creek. This time I crossed the creek on a plank near the washed-out bridge. This was a more direct route than the fallen tree upstream but only worked because the creek was low. At the crossing, a passing runner asked if he was on the Bulldog Loop. I assured him he was and was a little envious that he was getting to experience that excellent run for the first time.

As usual, Crags Road and the High Road were busy thoroughfares. The easy running under the sprawling coast live oaks was pleasant, and the morning view of Malibu Creek and Goat Buttes outstanding.

In a few minutes, I’d reached Mulholland Highway and then followed the Grasslands Trail to the Liberty Canyon Trail. From Liberty Canyon, the Phantom Trail gains about 750′ in elevation over about 1.5 miles to a high point and ridgeline with excellent views of Saddleback Peak, Las Virgenes Canyon, Brents Mountain, Goat Buttes, Castro Peak, Ladyface, and Boney Mountain.

The air quality this morning hadn’t been too bad. From up on the ridge, I could see there was far less smoke to the west of Las Virgenes Canyon than to the east. Yesterday, I’d done a run in the eastern Santa Monica Mountains and had to cut the run short because of smoke. That wasn’t a problem today, and the run had been a good one.

Poison Oak Along the Upper Sycamore Trail

The soft-hued reds and yellows of these changing poison oak leaves was accentuated by the soft, orange light of a smoky sky.

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.

Bobcat Fire Perimeter and Some Angeles National Forest Trails

Bobcat Fire Perimeter and Some Angeles National Forest Trails

For official information see the Bobcat Fire incident page on Inciweb and the Angeles National Forest website.  National Forests in California have reopened to varying degrees. For more information, contact the National Forest.

Here’s a Google Earth image of a Bobcat Fire perimeter from the National Interagency Fire Center (NIFC). The area inside the Bobcat perimeter is transparent yellow. Where the Bobcat perimeter overlaps older fire  perimeters, the area appears transparent orange. The image acquisition timestamp of the Bobcat perimeter is 10/6/2020 2045 (PDT) .

Also included are adjacent perimeters for the 2002 Curve Fire, 2002 Williams Fire, 2009 Morris Fire and 2009 Station Fire. Some trails in Angeles National Forest are also shown as yellow tracks. All map data are approximate.

Here’s a 3D interactive Cesium view of the 10/6/2020 perimeter and trails.

Angeles National Forest has partially reopened and issued Bobcat Fire Closure Order 05-01-20-08. The maps included in the Closure Order PDF are low resolution and poor quality. CalTopo has created an unofficial, but much more useful map, based on Closure Order.
