Padres' shooting star (Dodecatheon clevelandii ssp. patulum) and ground pink (Linanthus dianthiflorus) at Sage Ranch Park

This year's surprisingly generous rainfall is already producing an explosion of wildflowers in the Simi Hills and Santa Monica Mountains.

These are Padres' shooting star (Dodecatheon clevelandii ssp. patulum) and ground pink (Linanthus dianthiflorus) at Sage Ranch Park. Both are California natives.

An offshore wind scours out low-lying fog trapped in the Los Angeles basin by a low altitude temperature inversion.

This photograph of downtown Los Angeles and Century City was taken Sunday morning from the Backbone Trail in Topanga State Park while doing the Will Rogers - Temescal Loop from the "end of Reseda" in the San Fernando Valley.

At the time an offshore wind was scouring out low-lying fog trapped in the Los Angeles basin by a low altitude temperature inversion.

Mallow leaves tracking the sun.

Updated 03/13/08.

My run of the "keyhole loop" at Ahmanson Ranch started out as a tempo run -- not so much as being part of a rigorous training program, but because of a dead battery in my car remote. It felt good to push the pace a bit.

Part way through the loop, running up a short hill into the sun, I was struck by a repetitive pattern of backlit leaves in the new growth on and alongside the road. Like little green satellite dishes, hundreds of the round leaves of mallow (Malva neglecta) were facing directly into the late afternoon sun.

Mallow (Malva spp.) is an invasive plant from the Mediterranean area that has flourished in Southern California's Mediterranean climate. In most years, it is very common. I've run and hiked past thousands of these plants, but never noticed this synchronicity.

Tracking the sun makes sense. Our climate has an extremely variable and relatively short growing season. A plant that maximizes its intake of solar energy and growth by orienting its leaves toward the sun would have an advantage over a less adaptable species. This is probably one of the reasons mallow is such a successful invasive. Another invasive that grows alongside mallow, black mustard, also appears to exhibit heliotropism as it is growing. It creates a rosette of leaves facing into the sun by raising leaves on the side of the stalk away from the sun, and lowering leaves on the side of the stalk toward the sun.

Vernal pool near the sheep corral at China Flat in the Simi Hills.

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.

A trail runner on the Hidden Pond Trail in Pt. Mugu State Park.

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.

The photograph above is of the Hidden Pond Trail near Hidden Pond -- recently restored by Winter rains.

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.

Greening hill at Ahmanson Ranch -- now Upper Las Virgenes Canyon Open Space Preserve.

It's about time -- all the rain in Southern California is finally turning our hills green! Last year the hills of East Las Virgenes Canyon were sun bleached and rain starved.

According to preliminary NWS data, Downtown Los Angeles (USC) recorded measurable rain on each day from January 21 to January 28, 2008. Based on this NWS ranking for 1921-2006, this puts this eight day period in the top six of the station's wettest streaks from 1921-2007.

So far this water year Downtown Los Angeles has recorded 11.73 inches of rain, which is 4.77 inches above normal. Last year on this date Los Angeles had recorded only 1.5 inches of rain. Even if Los Angeles were to receive no rain through the entire month of February (not likely), we would still go into the month of March ahead of normal.

The photograph is from a muddy run at Ahmanson Ranch -- now Upper Las Virgenes Canyon Open Space Preserve.
