Red Box – Bear Canyon Loop

Running in Bear Canyon.

Bear Canyon

The creek burbled a gentle song of Spring, and downstream a Canyon Wren replied. Standing near the bottom of the narrow gorge, my eyes followed the soaring trunks of a grove of alders to their canopy of new leaves — backlit and bright green in the sun.

Bright green in the sun… In my run-altered state it was one of those aha! moments. The alders are just tall enough to reach from the shadows of the canyon into the sun – and – without the water in the stream that cut the canyon, the alders could not grow to the necessary height. The pieces fit — or was it the endorphins talking?

We were in Bear Canyon, west of Mt. Wilson, about 10 miles and 15 stream crossings into a 20 mile loop. An  idyllic hike along Arroyo Seco a couple of weeks before had reminded me of this wonderfully wild trail.



Our adventure had started at Red Box, on Angeles Crest Highway. Working east down the Gabrielino Trail to the West Fork San Gabriel River, snow could be seen glistening in the morning sun on Mt. Baldy’s summit slopes. There was no snow on our trail, just warm sun, buzzing bees and blooming manzanita. Continuing down the forested river canyon, we followed the Gabrielino Trail to Valley Forge, and then ascended the winding Valley Forge Trail to Eaton Saddle on the Mt. Wilson Road.

At the Mt. Lowe fire road gate at Eaton Saddle we were greeted by yellow warning tape and an “Unsafe for Travel” sign. What had happened? Did Mueller Tunnel collapse or something? Not inclined to turn back, we continued along the road, promising ourselves that we wouldn’t do anything reckless.



Other than the tracks of heavy equipment, nothing seemed out of the ordinary as we approached the tunnel. I had forgotten that the tunnel is curved, and for a moment was concerned when I couldn’t see the exit. But a couple of strides later the arched exit burst into view. The danger was an old one — an ongoing rock slide just beyond the western exit of the tunnel. There must have been a big slide recently. At the moment it was passable, and we figured as long as we didn’t stop under the slide, we’d probably be OK.

From Markham Saddle we followed the Mt. Lowe fire road out Mt Lowe’s elongated west ridge to a single track trail that leads down to Tom Sloan Saddle. From here, the Bear Canyon Trail descends into Bear Canyon following the route of the old Tom Sloan Trail.

Down in the canyon, I was glad to see that the neo-orange plastic tape that had marked the trail in 2007 was now tattered and faded, and not easily seen. Part of the enjoyment of a remote trail is its wildness. The trail descends the canyon — it has nowhere else to go. When progress is blocked on one side of the stream, it crosses to the other side. Plastic tape isn’t needed to show the way.



After many such stream crossings, we eventually worked our way down to the confluence of Bear Creek and Arroyo Seco. Along this reach there is a fantastic series of falls, pools and cascades. Gary Gunder and I were blown away by these drops when we kayaked Arroyo Seco down to JPL in 1998.

Following the Bear Creek trail upstream, we were careful not to miss the turn where the trail climbs steeply to the Gabrielino Trail and traverses above Switzer Falls. At Switzers Picnic area we parted ways — Miklos and Krisztina headed back to their car at Clear Creek, and I continued up Arroyo Seco to Red Box. It was a incredibly scenic and enjoyable trail run.

Here’s a Google Earth image and live Cesium ion view of a GPS trace of the Red Box – Bear Canyon – Switzers Loop. According to SportTracks the length of the loop was 19.5 miles with an elevation gain/loss of around 4000 ft.

Whatever route you use to get there, Sandstone Peak (3111 ft.) is a rewarding summit with sweeping views that range from the Channel Islands to Mt. Baldy and beyond. It is the highest peak in the Santa Monica Mountains, and a popular destination.

The peak is usually done as a steep 3-mile hike (round trip) from the Sandstone Peak Trailhead, or as part of a scenic 6-mile loop from the Mishe Mokwa trailhead. This National Park Service PDF provides additional information and a map of these trails.

A third option is to skip the drive to Yerba Buena Rd., and do the peak as an adventure hike/run from Wendy Drive trailhead in the Conejo Valley. This can be done by ascending one of the routes on the north side of Boney Mountain, then continuing up and over Tri-Peaks to the Mishe Mokwa/Backbone trail junction. From here the Backbone Trail leads to a spur trail that climbs the peak.

We took this last option and climbed Boney Mountain’s more technical western ridge. Done this way, it was about 6.8 miles to Sandstone Peak’s summit, with an elevation gain of about 3100 ft. This includes the short side trip to the high point near the top of the western ridge generally referred to as “Boney Mountain.”

Here’s a view west from Sandstone Peak of the Boney Mountain summit area. Tri-Peaks is the rocky peak on the skyline, right of center, and Big Dome is to the right of Tri-Peaks. The route up the western ridge tops out on the crest between these two peaks. (As seen from Sandstone Peak.)

The basic choices for getting back to the Wendy Drive trailhead are to go back down one of the trails on Boney Mountain’s north side; descend the Chamberlain Trail to the Old Boney Trail, and then loop back over the shoulder of Boney, or descend to Big Sycamore Canyon and then return from there.

Miklos and Krisztina had not run down Boney’s eastern ridge, so they backtracked over Tri-Peaks, and descended the use trail to the Danielson cabin site. I was looking to do some additional mileage, so ran down the Chamberlain, Old Boney, and Blue Canyon trails to the Danielson multi-use area in Big Sycamore Canyon, and then up Sycamore Canyon to the Upper Sycamore Trail, and back to Satwiwa.

Here’s a  Cesium ion view of a GPS trace of my route. The eastern ridge route is also shown.

Malibu Creek State Park Shadow & Sun

Malibu Creek State Park

My trail running shoes had not been wet or muddy since sometime in December. During the entire month of January, Downtown Los Angeles (USC) recorded about one-third of an inch of rain. Not only had it been dry, it had been warm. On a dozen of those January days, the high temperature topped eighty degrees, setting a new record!

But Winter had returned. The past three days, Los Angeles had received about 1.5 inches of rain, valley and foothill locations 2-4 inches, and some mountain stations as much as 5-7 inches. And more Winter weather was on the way. Excited about the change in the weather, today’s run was one with good muck and mire potential — the Bulldog Loop in Malibu Creek State Park.

We were not disappointed. Near Century Lake, mud the consistency of peanut butter pulled at our shoes and slowed the climb up Crags Rd, Further west, near the M*A*S*H site, calf-deep water on the trail washed the gunk off.

The trail conditions on the remainder of the loop were more straightforward. From time to time, shafts of sun would pierce the clouds, resulting in a patchwork of shadow and sun that emphasized the rugged terrain. Along the crest, the ocean views were superb! Before descending to Tapia Park we ran out to Mesa Peak, and then followed the ridgeline to an overlook of the coast. (Marked peak 1800 on the topo.)

Including the side trip to the overlook, this variation of the Bulldog loop worked out to an exhilarating 16.5 miles, with an elevation gain/loss of about 2700 ft.

If current forecasts and outlooks for this month hold true, this won’t be our last wet and muddy trail run this February. In a couple of weeks, Los Angeles rainfall totals may climb above normal for the first time this rain season. We’ll see!

Serrano Valley – La Jolla Valley Loop

Boney Mountain and Serrano Valley from the Ray Miller Trail.

The idea was to do an interesting trail run that wasn’t quite as long and strenuous as last week’s Bandit 30K Course Preview. That was the idea. I could have calculated the mileage and elevation gain of our projected route, but sometimes part of the fun of trail running is not knowing the exact route, how long it will take, or how strenuous it might be.

This particular exploration would visit two of the most scenic areas in the Santa Monica Mountains — Serrano Valley and La Jolla Valley. Many variations of this loop are possible. Our base route included the Ray Miller/Backbone Trail, Fireline Trail, Serrano Canyon Trail, Serrano Valley Trail, Old Boney Trail, Wood Canyon Vista Trail, La Jolla Valley Loop Trail, La Jolla Canyon Trail and connecting roads.

In addition to its wonderful scenery, this course is characterized by moderate uphills that are generally very runnable. The side trips to to the old ranch site in Serrano Valley, and to Mugu Peak pushed the route beyond the 30K mark, but were worth every step. Here’s a Google Earth image and Google Earth KMZ file of a GPS trace of the route. Since none of us had done the eastern leg of the La Jolla Valley Loop Trail, this time we did Mugu Peak from the east. The route around the valley to the western side of Mugu Peak is also shown.

Here is a Live Browser View of the run.

Bandit 30K Course Preview

View on Bandit 30K course in Rocky Peak Park.

Because of a scheduling conflict, two friends weren’t going to be able to enter a challenging new Southern California trail race — the Bandit 30K/14K — so today we previewed the 30K course.

The race starts in Corriganville Park in Simi Valley, and incorporates several of my favorite local trails in Rocky Peak Park. With an elevation gain in excess of 3200 ft., and varied terrain, the race promises to be a memorable test of trail running skill and endurance. A plus is that it is being run in March, when the hills are green; there is water in the creek crossings; and wildflowers along the trails.

So how was the 30K course? In a few words — strenuous, scenic and technical — and more difficult than either the Boney Mountain 21K or Bulldog 22K.

Note: The Bandit Trail Runs are now Rocky Peak Trails.
