In normal to wet rain seasons vernal pools can be found throughout the Simi Hills. The pool pictured above is near the sheep corral at China Flat, and another small pond was found nearby, along Albertson Motorway fire road. I've also found vernal pools in the Rocky Peak area and near Sage Ranch.

Geologically, the Simi Hills are characterized by the sandstone rocks of the Chatsworth formation. These inclined layers are of varying hardness, and erode at different rates. It's my guess that water collects in sandy soils between, or at the base of, the more resistant layers.

The photographs of the ponds at China Flat are from Sunday's Scenic Route to Simi Peak run.

When the rainy season turns wet and the grasses green, all routes to Simi Peak are scenic, but the varied trails and terrain, and the wilderness feel of the more remote sections of this 21.5 mile run makes it one of my local favorites.

It is a longer variation of the route described in the post Upper Las Virgenes Canyon Backcountry. The run starts at the Victory (or Vanowen, or Las Virgenes) trailhead of Upper Las Virgenes Canyon Open Space Preserve and explores the headwaters of Las Virgenes Creek. At the junction of the power line service road and "backcountry" trail, instead of turning south up the power line service road, this option works west over to Albertson Motorway fire road, and on to China Flat and Simi Peak.

Here's a Google Earth image and Google Earth KMZ file of a GPS trace of the route.

Wow -- what a great ride! That was my impression the first time I used the Salomon XT Wings trail running shoes. That continues to be my feeling after using the shoe for a couple of weeks and doing several runs in the 15-20 mile range. For my particular trail running requirements, this shoe has a near perfect balance of comfort, smooth ride, cushioning, traction and support.

Southern California can have inclement Winter weather. This January downtown Los Angeles experienced a streak with 8 days of measurable rain, and last year temperatures in the suburbs plunged to a frigid 20°F. Maybe this doesn't compare to Seattle's 2005-2006 rain streak of 27 days, or International Falls' recent record low of 40° below zero, but it qualifies as rainy and cold none the less.

Today it was not rainy and cold. It was just about as pleasant as a day could be. Skies were blue, winds were light, and the temperature was in the mid-seventies. Starting at the Wendy Dr. trailhead on Potrero Rd., we enjoyed the perfect weather by doing a 14.5 mile variant of the Boney Mountain Half Marathon Course.

Update May 18, 2008. Gov. Schwarzenegger's revised state budget, released May 14, rescinded the funding cuts that would have resulted in the closing of 48 California state parks. For now it appears these state parks will remain open. For more information see the Save Our State Parks and Campaign To Save Topanga State Park web sites.

What a fantastic morning! Taking advantage of a break in a series of Southern California rain storms, I was running on Fire Road #30 near the entrance of Topanga State Park. The sun had found its way through a broken layer of clouds, and bright patches of sunlight highlighted the rugged terrain. Down in a steep canyon on my left, wisps of steam wafted from the chaparral.

Following an  "On your left!" a group of mountain bikers swept past. Working up the hill toward the Hub, good morning's were exchanged with other runners, hikers and cyclists.

Many of us live and work in California because of its diverse open spaces, parks and wilderness areas. Incredibly, this popular urban park, along with Will Rogers State Historic Park, Santa Susana SHP, Los Encinos SHP, Mt. San Jacinto SP, and forty-four other California State Parks have been slated for closure in the fiscal year 2008-09 California state budget.

According to an article in the Los Angeles Times, the selection was made according to the dour formula of those parks "that had the fewest visitors, produced the least revenue and would be the easiest to close off to visitors."

This formula necessarily targets less developed parks, such as Topanga State Park, ignoring those intrinsic values that make a park a park. The formula targets walk-in parks, and the hikers, cyclists, riders, and runners that simply enjoy the outdoor experience. The formula targets day use parks in urban areas that don't need campgrounds or additional services. And, the formula targets those with less to spend on recreation.

So is this how we are to appraise the value of our public lands? Closing our state parks would be astonishingly short-sighted. Their varied trails, terrain, and habitats are accessible to millions, providing a therapeutic escape from the rigors of city life, and experiences and insights that can only be gained from the out of doors.

Today I was doing one of my favorite runs in Topanga State Park. It links several trails and visits several popular destinations in the park -- the Hub, Parker Mesa Overlook, Trippet Ranch, Eagle Rock, and the Musch, Garapito and Bent Arrow Trails.

This two minute slide show is a compilation from a few such runs. It is a small selection of photographs from one set of trails, in just one state park.
