The Red Box – Bear Canyon – Switzer’s Loop trail run is a favorite I’ve enjoyed doing for many years. Part of its attraction is the isolated, backcountry feel of Bear Canyon, particularly between Tom Sloane Saddle and Bear Canyon Trail Camp. It’s worth spending a few minutes at the old cabin site in the upper canyon to contemplate a lifestyle from an earlier century.

The descent of Bear Canyon is always adventurous in some way. Based on what I’d been seeing on other trails this year, I’d expected upper Bear Canyon to be a mess. I had braced myself for downed trees, washouts, and overgrown, hard-to-follow sections of trail.

But just a few minutes below Tom Sloane Saddle, a tree blocking the trail had been cleared, and the saw cuts were fresh! As I worked down the trail, I was excited to find more trailwork had been done. Branches or trees that had fallen across the trail had been cut. Some overgrown sections of trail had been trimmed. One washed-out section of trail looked like it had just been repaired. Someone had even trimmed a little of the poison oak that is so common along the trail.

As I discovered when I encountered them lower in the canyon, the Bear Canyon Trail Crew had been hard at work, and they were working in the canyon again today!

The last time I was in Bear Canyon (April 2021), the creek had been nearly dry. This year there was plenty of water and plenty of stream crossings. Unlike several recent runs, I had my poles and was able to keep my shoes and socks mostly dry.

I had debated whether to do this loop on Memorial Day Weekend. It passes through Switzer’s Picnic Area, one of the most popular day-use areas in Angeles National Forest. Many visiting Switzer’s do the hike down the Gabrielino Trail to see Switzer Falls, and many of those continue down the Bear Canyon Trail to the area below the falls.

Today, the two-mile stretch from below the falls to Switzer’s was as busy as expected. One issue I hadn’t anticipated was that some stream crossings were backed up like the Hillary Step on Everest. Other than wading, there was usually only one “dry” route across the stream. At one busy crossing, a hiker — clutching a dog under each arm — deftly balanced across a sequence of slippery rocks and branches, keeping his and his charge’s feet dry.

Once past Switzer’s, things returned to normal. From Switzer’s, it’s about 4.5 miles up to Red Box, with an elevation gain of about 1350′. I had been on this section of the Gabrielino Trail about a month before and was curious to see if a mass of fallen trees blocking the trail had been removed.

The trees still needed to be cleared — Forest Service rules require a qualified sawyer to do that kind of work — BUT the remaining 2.5 miles of trail to Red Box were being trimmed and cleared by several dozen members of the Mt. Wilson Bicycling Association. I wondered why I wasn’t seeing any mountain bikers on the trail — they were all working on it!

The bloom of Yellow Mariposa Lily along the Chumash Trail in Simi Valley has been extraordinary this year. Above, it is pictured with Golden Stars.

Among the multitude of wildflowers blooming along the trail this May were the showy Butterfly Mariposa Lily and intensely blue Parry’s Larkspur.

Running, Hiking and Riding Just Got a Little Easier in Some Parts of Ahmanson Ranch

Dirt roads used to service gas pipelines that pass through Ahmanson Ranch have recently been scraped and graded.

The work was sorely needed. In the wake of our very wet rain season, in some areas the mustard was 8 feet tall and roads were rutted and damaged.

All of the scraped roads are in the western part of Ahmanson, primarily in and near upper Las Virgenes Canyon. Some very welcome weed-cutting was previously done along the roads in other parts of the open space area.

(Officially named Upper Las Virgenes Canyon Open Space Preserve, most users refer to the open space area as Ahmanson Ranch or simply Ahmanson.)

A Really Overgrown Trail, Thirty Creek Crossings, and Thousands of Wildflowers

Starting at the Wendy Drive Trailhead, I’d crossed Satwiwa, run down Danielson Road, rock-hopped across Upper Sycamore Creek, and picked up the Old Boney Trail. The condition of the Old Boney Trail between Danielson Road and the Fossil Trail junction was better than expected. Maybe the trail was going to be in good shape after all.

Wrong! Once I passed the turnoff to the Fossil Trail, the vegetation closed in. In places it was so thick I couldn’t see the trail at my feet, much less a few yards ahead. All I could do is smile and work my way through it. Everything was overgrown — bushes, grasses, wildflowers. And everything was wet with dew. A hundred yards past the Fossil Trail, I was soaked from head to toe.

I tried to see the positive. It was an amazing display of the effect of a wet rainy season. Without trail work and use, it wouldn’t take long for the trail to be completely consumed.

The Old Boney Trail continued to be a tangle of chaparral for about two miles — until I reached the Backbone Trail at Blue Canyon. At that point, it becomes part of the Backbone Trail system, and I was relieved to see that some work had recently been done on the trail.

As I worked up the Backbone Trail toward the Chamberlain Trail junction, I recalled other times I’d run to Serrano Valley using Old Boney. What would the condition of the trail be beyond this point? I’d been on that part of the Old Boney Trail following a wet rain season and knew how overgrown it could be. Some refer to that section of trail as “tick alley.”

But when I got to the junction, surprise, surprise, the Old Boney Trail had been trimmed. More than two miles of trail were groomed. It was good all the way to the Serrano Valley Trail and partway into Serrano Valley. The trail in Serrano Valley was a little overgrown, but NOTHING like the Old Boney Trail between the Fossil and Backbone Trails.

Part of the fun of doing this route is all the stream crossings in Serrano Canyon — what is it 13 or 14? Today, most of these could be done without getting your shoes wet — especially if you have poles. I didn’t have poles, and my shoes and socks were already wet, so I didn’t worry about keeping them dry. Some sections of the Serrano Canyon Trail were also overgrown, but not bad. However, there was a lot of poison oak, some of which wasn’t avoidable.

After getting a drink of water at the faucet at the junction of the Serrano Canyon Trail and Sycamore Canyon Fire Road, I headed up-canyon. Almost immediately, the fire road crossed Big Sycamore Canyon Creek. I did this first crossing without getting my shoes wet, but nine more crossings followed, and most resulted in soaked shoes. The water crossings and wildflowers helped distract me from the five mile run up Sycamore Canyon to the Upper Sycamore Trail.

Getting off Sycamore Canyon Road and onto the Upper Sycamore Trail was a relief. Whatever run I do from Wendy Drive, I always finish it via this trail. The trail gets enough use that it was in good shape. This time all the creek crossings could easily be rock-hopped.

Even with a few tedious sections, it was an adventurous and mostly enjoyable 20 miles. Here are some photos taken along the way.

Afternoon Run on the Forest and Lost Cabin Trails in Malibu Creek State Park

The seasonal bridge across Malibu Creek is back! No sketchy log to test your balance or thigh-deep water to wade through — just walk across.

This afternoon I’d returned to Malibu Creek State Park to check on the bridge, count the surviving coast redwoods on the Forest Trail, and see what was happening on the Lost Cabin Trail.

When running the Bulldog Loop a couple of weeks ago, I did a quick check of some of the redwoods on the Forest Trail but skipped the back half of the trail. Today, I crawled through the downed trees blocking the trail and checked the rest of the trees.

I counted seven surviving redwoods. Several of these are  multi-tree groups consisting of two or more trees. These family groups  were counted as one tree. One of the trees, and perhaps more, was naturally germinated. Most of the trees looked healthy, but appearances can be deceiving.

One redwood is just a few feet from the Crags Road Trail. It’s on the right side of the trail, just past the seasonal bridge, when going west on Crags Road toward the M*A*S*H site. The unique conifer is easy to spot among the other trees.

The start of the Lost Cabin Trail is on the left as you enter the M*A*S*H site going west on Crags Road. Like the Forest Trail, it is less used and isolated but has a character all its own. Today, the Lost Cabin Trail was a trove of brightly colored wildflowers.

Here are a few photos taken along the way.

Upper Las Virgenes Canyon Trailhead Valley Oak

This large valley oak lives near the Upper Las Virgenes Canyon Trailhead of Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson Ranch). There used to be several large valley oaks near the trailhead, but they were killed in the 2018 Woolsey Fire.

The brim of the cap is about 7 inches wide.

This tree is as large as any of the valley oaks I see along the trails at Ahmanson. I estimate it’s diameter to be a little under four feet. That’s not large by Northern California standards, but it is still a sizable tree. Valley oaks have a tougher time here.

Along with coast live oak, the valley oak is one of the iconic species of oak-grasslands at Ahmanson Ranch. In the past 20 years, valley oaks at Ahmanson Ranch have been more severely impacted by drought, fire, and rising temperatures than live oaks. In the not too distant future, the valley oak may become a relic at Ahmanson, much like the blue oak that died earlier this year.
