Ahmanson 12K Preview

East Las Virgenes Canyon, Ahmanson Ranch

Race director Nancy Shura-Dervin picked a great year, and as it looks now, a great weekend for the inaugural running of the Ahmanson 12K Trails event.

The hills are lush and green; wildflowers are in bloom; valley oaks are sprouting fresh green leaves; and it’s looking like race day may be one of those “gotta run” kind of days.



According to today’s NWS forecast the area will see dry and warmer weather beginning Tuesday and continuing through race day. While there could be a remnant puddle here or there, four days will be plenty of time for the dirt roads to (mostly) dry out. The Cheeseboro RAWS automated weather station can be used to get an idea of the current weather in the vicinity of the race course.

Over the past 10 years I’ve logged approximately 6000 miles at Ahmanson Ranch (now Upper Las Virgenes Canyon Open Space Preserve) and the loop Nancy has selected for the course is a variation of a favorite.



Here’s a Google Earth overview of the 12K course and a preliminary elevation-corrected profile generated in SportTracks. The course is about 7.4 miles long with an elevation gain of about 740 feet. (Note: The loop is run in the clockwise direction.)



Lasky Mesa has long been used to shoot movies, television, commercials, music videos, and even Internet games. Its wildland character and expansive views bely its urban location. For a few weeks one summer the Mission Impossible III bridge was a Lasky Mesa landmark. The aesthetically-shaped valley oak at the west end of Lasky Mesa is a favorite of production companies and I’ve spotted it in more than one commercial.

The Ahmanson 12K should be an outstanding event on an excellent course in conditions we haven’t seen at Ahmanson in several years.

Chumash Trail Clouds and Sun

Cumulus clouds from the Chumash Trail

Instability associated with an upper low resulted in some pop-up showers and thunderstorms today.



As I ran up the Chumash Trail on the east side of the Simi Valley I kept a close eye on a cell that developed near Ladyface in the Agoura Hills. That cell didn’t track as much to the east as I thought it might, but other cells were developing to the east and south of Rocky Peak and Santa Susana Pass area and at one point I heard the rumble of thunder.

As it worked out, I only had a few sprinkles on the run, but drove home in the rain!

The rising sun illuminates a translucent layer of cloud trapped by a shallow inversion in the San Fernando Valley. The mid-level clouds above are associated with a system that brought heavy rain to much of California, but would only produce showers in the Los Angeles area.

Just Me and the Meadowlarks

La Jolla Valley from Mugu Peak

I had to stop running and take it all in. Soaked by recent rains, La Jolla Valley was renewed and green. To my right a meadowlark warbled its silvery call, and in the distance at first one and then another bird followed in song.

Isolated for weeks by the closure of Pacific Coast Highway and Pt. Mugu State Park, the La Jolla Loop Trail was trackless and in places overgrown. Wet with dew, the mustard choking the trail had soaked my shoes and socks.

Sprinkled among the greens were whites, purples, pinks, reds and yellows of the first stage of a wildflower explosion. A sweet scent drifted on the breeze. Running in the valley was like running in a remote and seldom-visited wilderness.



There had been much to see on the run from Wendy Drive. Before the Park closed in December I had surveyed the aftermath of the December 12 flash floods in Sycamore Canyon, Blue Canyon and Upper Sycamore Canyon. One of the reasons for today’s run was to see what had happened in this part of the Park.

Wood Canyon parallels Sycamore Canyon and is probably its largest tributary. Based on the height of the debris piled against the trees, the flash flood that roared down Wood Canyon must have been astounding! Looking down the stream course reminded me of flash floods I’d seen on creeks and streams during the El Nino’s of 1997-98 and 2004-2005.



Bowl-shaped La Jolla Valley is an independent drainage, separate from Sycamore and Wood Canyons and their tributaries. It acts like a huge rain collector and funnels all the runoff down deeply cut La Jolla Canyon to the ocean. In La Jolla Valley all the creeks were scoured by the flash flooding and the small footbridge west of the group campground was washed out. The vernal stock pool on the Loop Trail above La Jolla Canyon was once again full.



It’s no surprise that the December flash floods washed out the trail in La Jolla Canyon. I can’t think of a steeper and more narrow canyon in the park.  The flow must have been phenomenal! The La Jolla Canyon Trail is closed and barricaded at its juncture with the Loop Trail. Here are archived maps of Rancho Sierra Vista/Satwiwa and Pt. Mugu State Park originally from the NPS Santa Monica Mountains web site. Also see the Pt. Mugu State Park maps on VenturaCountyTrails.org.

In recent years the drought has dramatically reduced the number and variety of wildflowers blooming in the Santa Monica Mountains. Not so this year. Since October 1 Camarillo Airport has recorded 7.0 inches of rain, which is about 92% of normal. Last year over the same period only 0.84 inch had been recorded.



Many species are already blooming and many more will be blooming soon. On today’s run I saw shooting stars, encelia, lupine, nightshade, monkeyflower, paintbrush, California poppy, bladder pod, wild hyacinth, phacelia, wishbone bush and more. A small patch of chocolate lilies were in bloom along the eastern segment of the Loop Trail.

La Jolla Valley and Mugu Peak can be busy places, but today it was just me and the meadowlarks.

Update February 3, 2015. According to the Ventura Star six miles of Pacific Coast Highway from Las Posas Road to the Sycamore Cove Day-use Area reopened today providing access to Pt. Mugu State Park from the south. Note that the La Jolla Canyon Trail is still closed and likely to be for some time.
