I liked last weekend's run so much that this morning I returned to the Wendy Drive trailhead on Potrero Road and was now chugging up the Danielson-Old Boney trail, planning to do another circuit that would eventually take me back down into Big Sycamore Canyon.

I was about a mile from the Wendy Dr. trailhead on Potrero Rd. in Newbury Park. A cold wind ruffled the chaparral, and to the north snow could be seen on McDonald Peak (6870') and other peaks of the Ventura mountains. I was nearing the top of a rounded ridge in Rancho Sierra Vista/Satwiwa, and in a few minutes would be descending the sun-warmed Old Boney Trail into the upper reaches of Big Sycamore Canyon.

One of the most scenic and isolated areas of Upper Las Virgenes Canyon is traversed by a single track trail that links the Upper Las Virgenes Canyon fire road, northwest of Bell Canyon, to the northern extension of the Cheeseboro Ridge power line service road. The trail, shown on this Park Service map, follows an old road bed through improbable terrain.

I like to do the trail east to west. Once the power line service road is reached the most straightforward option is to turn left, and follow the road up and over the ridge and down to the 4-way junction east of Shepherds Flat. Another option is to turn right on the road and follow it a short distance to another single track that branches left from the road and leads to the Albertson Mtwy. This (dirt) road leads west to a signed intersection near China Flat. From here it is possible to work back to Shepherds Flat at the the top of Cheeseboro.

Many variations are possible, but starting at the Victory Trailhead of Upper Las Virgenes Open Space Preserve, and following the course indicated in this Google Earth image, the first route (up and over the ridge) is about 17.5 miles long. According to my GPS, an alternate route through China Flat is about 19.25 miles long. Both are interesting and challenging trail runs.

The numerous interconnecting roads and trails of the eastern Santa Monica Mountains can be combined to create trail runs ranging from a few miles to marathon length or more.

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.

Sandstone Peak and Boney Mountain from Simi Peak

I hadn't done this course in midsummer, but a long run close to home, and an early morning ascent of Simi Peak sounded like a nice change of pace. A dawn start from El Scorpion Park put me on the peak and back to the car before temps got out of hand.

The Lower Stagecoach - Hummingbird loop is a shorter, somewhat less strenuous alternative to the Chumash - Hummingbird and Chumash - Las Llajas loops. Approximately 6 miles long, about a mile of the route is on pavement, with the remainder on single track trail and fire road. The elevation gain/loss on the loop is about 1300 ft.

Each year, thousands hike, ride or run the 2.3 miles up Rocky Peak fire road to a high point with a nice view of Simi Valley. This is near the point marked "ROAD" in this overview photo. Many turn around here, but some continue along the main road to the Johnson Trail, Chumash Trail, Fossil Point, or beyond.

Another option is to follow a spur trail that branches off the main road at the high point about a quarter-mile to an airy overlook. From this viewpoint you can see the San Fernando Valley and surrounding mountains, and trace your route through Rocky Peak Park's unique sandstone formations.

The overlook marks the end of the "easy" trail and the beginning of a rough, rudimentary trail that leads east-northeast through large boulders and outcrops to the summit of the Rocky Peak (2714').

The summit of Rocky Peak is one of the points that defines the border between Los Angeles and Ventura counties. Last year, I was surprised to find evidence that a coyote had recently visited this summit!

Runner on a track that connects Rocky Peak fire road to Las Llajas Canyon in Rocky Peak Park. From the top of this hill there is approximately 4 miles of fast downhill through a scenic canyon garnished with out of service oil wells and a gurgling creek.

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.

A friend cruises down Calabasas Peak Motorway on the way to the Stunt High Trail, Backbone Trail, Saddle Peak, and Tapia Park – a run of about 14 miles with an elevation gain of about 2600 ft., and loss of about 3600 ft.

Several excellent trail runs in the 11-15 mile range (or longer) can be done from the intersection of Malibu Canyon and Piuma Rd., near Tapia Park. These include an out and back to Saddle Peak (~13 mi), the Bulldog Loop (~14.5 mi), and point to point runs starting at the Secret Trail (~11 mi), or Tunnel #1 on Kanan Rd. (~12.5 mi).
