September Storm

Rocky Peak road 

Los Angeles sometimes gets rain in September, but usually it is the result of tropical moisture from a dissipating hurricane, or perhaps the passage of the tail end of a weakening front. It is rare to see a low as cold, deep and energetic as the upper level low that deluged many areas of Los Angeles county Friday afternoon into Saturday.

Thunderstorms raked the San Fernando Valley Friday night, and several locations in and around the Valley recorded more than an inch of rain over the course of the storm. Los Angeles set a new rainfall record on Saturday, recording 0.40 inch of rain, and rainfall records were broken across the area.

In Southern California the first rain of the season often doesn’t occur until October or November and is always savored. Especially this year, when Los Angeles has recorded only 3.21 inches of rain in the last 15 or 16 months, and a developing La Nina threatens to put the kibosh on Winter rain.

I celebrated the rain by doing an out and back run to “Fossil Point” on Rocky Peak fire road. Based on the size of the mud puddles on the dirt road, this unseasonable storm appeared to be wetter than any in last year’s record dry rain season. Here’s a panorama of the view northwest from the fire road to Oak Ridge, the Santa Susana Mountains and beyond.

Rain Gauge

The stalk height of Elegant Clarkia (Clarkia unguiculata) is a good indicator of seasonal rainfall.

One of the best indicators of seasonal rainfall I’ve found in the oak woodland and chaparral areas of Southern California in which I run is Elegant Clarkia (Clarkia unguiculata). In a wet year it can grow more than 6 ft. tall. This year it is the shortest I’ve ever observed — about 5 inches in this photo taken near Lasky Mesa.

New growth on the chaparral shrub laurel sumac (Malosma laurina) at Sage Ranch Park. The red pigment may function as a sunscreen, protecting sensitive new leaves until they mature, and can cope with full sun.

In mid January there was widespread freeze damage to laurel sumac in the Santa Monica Mountains, and other wildland areas near Los Angeles. Although the plant pictured above was not damaged, many laurel sumac plants in low lying and wind protected areas were.

But frost, fire or drought, laurel sumac is a resilient plant that can weather most hazards. At Sage Ranch, many of the plants damaged in the January freeze have already sprouted new growth.

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.

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.

Shooting Stars

Shooting stars (Dodecatheon clevelandii) at Sage Ranch Park, in the Simi Hills, northwest of Los Angeles.

Shooting stars are among the first wildflowers to bloom following soaking Winter rains. These appear to be Dodecatheon clevelandii ssp. patulum.

The flowers produce a semitransparent, otherworldly seed capsule that traps moisture. This is an adaptation to an environment that may be cool and damp one day, and then hot and dry just a few days later.

Ahmanson Lollipop Tree

The Ahmanson lollipop tree can be seen on the skyline south of the main drag about 1.25 miles from the Victory trailhead.

On the South Fork American River is a tree high on a ridge that rafters and kayakers refer to as the Lollipop Tree. It marks the beginning of the Gorge run and the class III rapid “Fowler’s Rock.”

When I run on the “main drag” at Ahmanson Ranch (Upper Las Virgenes Open Space Preserve) there is an oak tree that sits on a hilltop near Laskey Mesa that reminds me of the S.F. American tree. The Ahmanson lollipop tree can be seen on the skyline south of the main drag about a mile from the Victory trailhead.

This photograph was taken on an exploratory out and back run to the headwaters of Las Virgenes Creek on Christmas Eve.

Note: Jon Sutherland nicknamed the main road that connects the Victory trailhead to Las Virgenes Canyon the “main drag.” Jon has run out at Ahmanson for more than 30 years. He is second on the Running Streak List for most consecutive days run. As of September 1, 2006 his streak was 13,613 consecutive days (37 years 99 days), and still counting!
