Strawberry – Bear Canyon Loop

Trail runner in Bear Canyon, in the San Gabriel Mountains.

The Strawberry – Bear Canyon loop trail run is a longer, more adventurous variation of the run around Strawberry Peak described in the post Strawberry Peak Circuit.

The photograph Fall Leaves On Bear Creek was taken on this loop in November 2005. As described in that post, instead of descending directly to Switzer’s from Red Box, this route descends the West Fork to Valley Forge Campground and then climbs up and over the shoulder of Mt. Wilson, and down into Bear Canyon, eventually working its way back to Switzer’s and Clear Creek.

Without any wrong turns or other route finding issues the loop works out to about 25.5 miles with an elevation gain and loss of about 5500-6000 ft. The running (and hiking) is extremely varied, including fire roads, old road beds, easy trail, technical trail, and lots of up and down. Bear Creek’s lush canyon is gorgeous, but 20 miles into the run, it’s winding course and many creek crossings can prove demanding.

I attempted to obtain a GPS trace of this route in 2005, but the steep, narrow canyons defeated my Foretrex 201. Not so with my Forerunner 205. I continue to be amazed at the 205’s performance. Here’s a Google Earth image and Google Earth KMZ file of the GPS trace of my route.

California prickly phlox (Leptodactylon californicum) likes warm, rocky, southwest facing slopes.

A Winter bloomer, California prickly phlox (Leptodactylon californicum) likes warm, rocky, southwest facing slopes where it can bask in the afternoon sun. The flowers have a subtle, musty-sweet fragrance that is especially pleasant when encountered on a still evening, in fading twilight, near the end of a run.

Cheeseboro Bound

Two runners climb up the last yards of a hill before descending into Las Virgenes Canyon in Upper Las Virgenes Canyon Open Space Preserve.

The trail is a connector that joins East Las Virgenes Canyon with upper Las Virgenes Canyon. Our 15 mile loop started at the Victory trailhead, following the El Scorpion Trail to another long-used trail that climbs up to the ridge along the northern boundary of the preserve. From here we descended to Las Virgenes Canyon and worked over to Shepherd’s Flat and down Cheeseboro Canyon, eventually returning to the Victory trailhead by way of the main drag.

The area seen in the photograph is a small portion of the 24,000 acres that was burned in the Topanga Fire in late September 2005.

Although an undercoat of green is apparent, the drought in Southern California continues. According to NWS climate data, as of today, Downtown Los Angeles (USC) has recorded only 2.42 inches of rain since the water year began on July 1, 2006. This total is nearly 9 inches less than normal.

Chaparral Freeze

Freeze damaged Laurel Sumac in Malibu Creek State Park.

Updated March 6, 2007

As evidenced by their survival, native plants are generally well adapted to the environment in which they live. Fire, flood, drought, heat or cold, they’ve seen it all – or nearly so.

On January 14, 2007 many new record low temperatures for the date were set in the Southern California area. Several locations in the San Fernando Valley recorded temperatures in the 20’s. Pierce College in Woodland Hills plunged to a record low of 20°F (-6.7°C).

The freezing temperatures resulted in extensive damage to fruit crops, nursery stock, and landscaping. The brown leaves of freeze damaged shrubs, trees and other plants are a common sight in the Los Angeles suburbs.

Since the freeze, I’ve run in several areas of the Santa Monica Mountains, Santa Susana Mountains and Simi Hills, and most native chaparral shrubs appeared to have weathered the cold temperatures well, exhibiting very minor, if any, visible damage. However, there are some exceptions.

One obvious exception is laurel sumac (Malosma laurina). I first noticed instances of laurel sumac with damaged leaves and stems on a run at Sage Ranch on January 24. Initially, I thought the damage might be limited to sprouting laurel sumac in the 2005 Topanga Fire burn area, but on subsequent runs damaged plants were seen in several areas unaffected by the fire, including Topanga and Malibu Creek State Parks. Now that the dead leaves and stems have turned brown, the affected plants stand out in the chaparral, and the extent of the damage is easy to see.

The sensitivity of Laurel Sumac and other chaparral plants to freezing temperatures and drought has been studied extensively by Dr. Stephen Davis of Pepperdine University’s Seaver College Biology Department. This research confirms that the leaves and stems of laurel sumac are not as tolerent of freezing temperatures as some other chaparral shrubs. This reduced tolerance probably affects the distribution of the plant, favoring its growth in warmer coastal locations and inland microclimates.

Dr. Davis reports that, in addition to laurel sumac, other species that have been damaged at the lower, colder distributions in the Santa Monica Mountains include green bark ceanothus (Ceanothus spinosis), big pod ceanothus (Ceanothus megacarpus), sugar bush (Rhus ovata), and some hairy-leaf ceanothus (Ceanothus oliganthus). The lowest temperature recorded at his field sites was 10.4°F (-12°C).

A factor in the damage is that the freeze occurred during a period of relative drought. As of January 14, Downtown Los Angeles (USC) had recorded only 1.31 inches of rain since (but not including) May 22, 2006 – a period of nearly 8 months.

Although some of laurel sumac’s adaptations to fire and drought may adversely affect the resistance of its foliage to freezing temperatures, it is precisely these adaptations that will enable most of the freeze damaged laurel sumacs to resprout and survive.

The photograph of freeze damaged Laurel Sumac was taken on the Backbone, Bulldog & Beyond run.
