Clearing clouds, northwest of Los Angeles, following the passage of an upper low storm system that resulted in widespread rainfall in Southern California.

Clearing clouds, northwest of Los Angeles, following the passage of an upper low storm system that resulted in widespread rainfall in Southern California. Several rainfall records for November 26 were broken in Los Angeles County.

Update 12/5/08 P.M. High amplitude flow continues to wreak havoc with forecasts. Our on-again, off-again chance of a shower this weekend might be on again. Original cut-off upper low center is still well offshore, but another low center has developed on the downstream side of high amplitude ridge, and this one is much closer to the Southern California coast. The low appears to be entraining some moisture, and could produce some showers, particularly as the low moves onshore and is absorbed in the main flow. We’ll see!

Update 12/5/08 A.M. No rain is expected in SoCal this weekend… The cut-off upper low set up much further west than suggested by models Tuesday and now is spinning out in the eastern Pacific, nearly halfway to Hawaii. At the moment, it looks like it could be mid-month before our next chance for significant rain.

Update 12/2/08. Computer models have been having a tough time with both the short and medium term forecasts for Southern California. Recent runs have been hinting at the possibility of some rain Saturday or Sunday. This would depend on the strength, position and behavior of an upper low that is forecast to form off the Southern California coast Thursday.

From a run at Sage Ranch Park, near Simi Valley, California.

Twenty-Two Miles and Two Classic Climbs

The West Fork San Gabriel River at the Rincon-Edison road crossing.

We stopped for a few moments at the river crossing, where water stood in pools waiting for Winter rain. Instead, cold air flowed down its course, cool and refreshing. From this point there would be little shade. Rarely cold, the climb out from the West Fork San Gabriel River to Shortcut Saddle is often warm, and sometimes debilitating.

Miklos, Krisztina and I were doing the Shortcut Saddle – Mt. Wilson loop — an approximately 22 mile loop that includes two memorable climbs from the Mt. Disappointment 50K and 50M runs. The loop also incorporates the Rim Trail, an adventurous trail that is rough, steep, and washed out at points, but also includes long stretches of excellent trail running. The route starts with almost four miles of downhill on the the Silver Moccasin Trail — a good warmup and a great way to start a trail running day.

Thankfully, today the weather was cool and the Fall shadows long. This translated to more running and a faster pace up Rincon-Edison road. Even so, we were happy to reach the point where the Silver Moccasin Trail shortcuts the last long switchback of the road, and followed this more direct route up to the trailhead.

Our variation of the climb from the W.F. San Gabriel River to Shortcut Saddle on the Rincon-Edison Road was about 5.6 miles long, with an elevation gain of about 1925 ft.  The climb from the W.F. San Gabriel River at West Fork campground up the Gabrielino and Kenyon DeVore trails to the Mt. Wilson parking lot worked out to about a 2550′ elevation gain in 5.2 miles. The total elevation gain for the loop is about 4500′.

Fossil Trail – Pt. Mugu State Park

Shell impressions on the Fossil Trail in Pt. Mugu State Park.

The Fossil Trail is a steep, approximately mile-long trail in Pt. Mugu State Park that connects the Upper Sycamore Trail, near its junction with Sycamore Canyon Road, to the Old Boney Trail. The most obvious fossils are shell impressions and remnants found in an exposed layer of sandstone about a tenth of a mile below the Old Boney Trail junction. Some of the shell impressions are palm-sized and larger.

The shells appear to be a type of cockle (Anadara devincta) that is an indicator of Miocene-age formations. (See the Oregon Sea Grant publication “Fossils You Can Find on Oregon Beaches.“)  In this case, the fossil exposure appears to be in the Lower Topanga Formation, which is believed to have been formed in the middle to early Miocene, about 20 million years ago.

The shape, thickness and ribbing of this type of shell increases its strength and resistance to crushing — improving the shell’s chances of remaining intact when buried in sediment, and during subsequent geologic processes. This may be one of the reasons it is a prevalent indicator fossil.

The photograph is from Sunday’s run from Wendy Drive to Serrano Valley.

Serrano Valley from Wendy Drive

Descending to Serrano Valley in Pt. Mugu State Park

Scruffy clouds clung to the mountain ridges and summits, confirmation that a weak cold front was moving through the area, cooling temperatures and stirring up the wind. The forecast for the Santa Monica Mountains National Recreation Area had mentioned 25 to 35 mph winds with gusts to 60 mph. So far the weather in Pt. Mugu State Park had been nearly perfect — breezy and little chilly, but without the impenetrable winds that can take all the joy out of running.

Earlier we had climbed the Fossil Trail, a steep mile-long trail that connects the Upper Sycamore Trail, near its junction with Sycamore Canyon Road, to the Old Boney Trail. With only a few weeks remaining to the Solstice, shadows in the canyon were long and the light wintery. I thought we might have missed the fossils, but we happened on a nice exposure about a tenth of a mile below the Old Boney Trail junction.

About 5.5 miles later, we turned off the Old Boney Trail and descended to the rolling grasslands of Serrano Valley, another “must see” area of the Santa Monica Mountains.

Located on the east side of Big Sycamore Canyon, Serrano Valley is a more rugged counterpart to La Jolla Valley, just three miles to the west. Overseen by the castle-like summits of Boney Mountain, its vistas have a roughhewn edge, reminiscent of the most wild areas of the western U.S.

Here is a Google Earth image and Google Earth KMZ file of a GPS trace of our approximately 19 mile route to Serrano Valley and back to Wendy Drive.

Sesnon Fire Recovery – First Growth

Terminal budding in yerba santa 3 weeks after the 2008 Sesnon Fire.

Only three weeks after the area was burned in the 2008 Sesnon Fire, this yerba santa shrub on the Chumash Trail has started the process of foliage replacement. In many areas along the trail, grasses and other annuals (many invasive) were consumed, but adjacent chaparral shrubs were only scorched. Many of these shrubs look like they will be able to recover through budding of existing stems, rather than crown-sprouting.
