Pushed up and over Boney Mountain's two thousand foot western escarpment, Pacific winds condense into thick cloud along its jagged crest. At times breaking free of the mountain's grasp, patches of cloud drift eastward, creating a patchwork of sun and shadow on the steep slopes, and in the valley below.

In the distance, the Ventura Mountains gleam with a mix of snow and cloud, and below the fields of Satwiwa stand out vibrant and green. At my feet hundreds of purple shooting stars dance in the wind; and nearby yesterday's rain seeps and trickles from moss to lichen on the scraggy volcanic rock.

It is a remarkable morning, and an exceptional one to be doing the Boney Mountain north side loop. Here's a short HD video of some of the views along the way. (If the video doesn't play cleanly the first time through because of bandwidth issues, let it finish and then try playing it a second time.)

From today's run in the Malibu Hills.

Winter into Spring the purple flowers of wishbone bush (Mirabilis californica) are found along sun-warmed sections of low elevation trails in much of Southern California.

The plant's common name refers to the stems of the plant, which are repeatedly forked.

Green hills, partly cloudy skies, and superb trail running in Lang Ranch Open Space, near Simi Valley California.

From this morning's "see how worked my quads are after the Twin Peaks 50K" run at Sage Ranch.

The answer -- pretty worked!

The weather has calmed in Southern California. Medium range models are forecasting a break of about a week in what has turned out to be a very busy rain season. Over the last 90 days a precipitation pattern typical of El Niño has emerged in the western U.S. This is reflected in rainfall total for Downtown Los Angeles (USC), which is now at 13.2 inches for the water year -- 4.78 inches above normal.

The dry weather could not have come at a better time for those affected, or threatened, by mudslides and debris flows. This small slump along a road at Ahmanson Ranch is indicative of the instability that can develop when soil becomes saturated. Had our recent wet pattern been more persistent, mudslides and debris flows might have been much more widespread and devastating.

Nature isn't necessarily nice. Behavior and interactions among animals are often violent. So it is with mountain lions. But the mountain lions of the Santa Monica Mountains also have to cope with the additional problems of living on an island of lion habitat in the middle of an ocean of urban sprawl.

The mountain lion tracks above were photographed on a run at Sage Ranch Park in late January 2000 . They might have been made by a young male mountain lion designated P3, whose territory encompassed this area. There is also a possibility there were from an older female lion, P4 that frequented the Rocky Peak area. Unfortunately both these animals were killed in late 2004 by eating prey (coyote) that had eaten rodents that had consumed anticoagulant based poisons. These poisons are used by parks, schools, golf courses and housing developments for rodent control.

The P3 and P4 pumas were tracked as part of a ongoing study started by the National Park Service in 2002 to learn more about mountain lions in the Santa Monica Mountains National Recreation Area. As of mid January, 2010, fifteen mountain lions, P1 to P15, have been tracked, and their history has been quite a saga.

The patriarch of the lions in the study is P1. He was the first lion captured and collared in 2002, and at that time was estimated to be 5-6 years old. In his prime, P1 was a large, 140+ lb. male whose territory was essentially all of the Santa Monica Mountains. In August of 2004, P1 and P2 - the only female lion known to be in P1's range - produced a litter of four cubs -- two males (P5 and P8) and two females (P6 and P7).

California peony is fairly common in the Santa Monica Mountains and other lower elevation, open space areas of Southern California. It can be found in a variety of habitats, including Coastal Sage Scrub and Chaparral.

It is a perennial, and has adapted to our demanding climate by dieing back when conditions become hot and dry.   Its leaf growth tends to parallel that of annual grasses, and as these grasses become long, lush and green following early Winter rains, you'll usually find flowering peonies somewhere in the area.

From Saturday's trail run in Malibu Creek State Park.

While running the Phantom Trail a couple weeks ago, it occurred to me that the Grassland, Talepop, Liberty Canyon and Phantom Trails could be combined with the Bulldog Loop to create a challenging -- and very scenic -- twenty-something mile trail run.

Just how much longer than twenty depends on which trails you use to connect the Phantom Trail to Crags Rd. I opted to use the Cistern, Lookout, Yearling, and Deer Leg Trails. This variation works out to a little more than 24 miles. Tack on an out and back to the Mesa Peak overlook and you have a marathon length scenic tour of Malibu Creek State Park!

Here's a Google Earth browser view of a GPS trace of my route.

The title photo is a view west from the Cistern Trail to the former site of the Reagan Ranch.

Note: Check for ticks when running here -- particularly in the Winter & Spring!

One of about a dozen vernal pools in the Rocky Peak area. More than just a puddle, these rainy season pools form as a result of the area's unique geology.

In my experience, excessive rainfall is not necessary for the pools to form. Normal month-to-month seasonal precipitation is usually sufficient. Their persistence depends on several factors, but in a season with normal to above average precipitation, the pools can last for several months.

From Wednesday's run on Rocky Peak.
