A good way to think of this adventure is as an excellent 17 mile trail run on the PCT north from Walker Pass (5217'), combined with a three mile scramble up and down the rocky southwest ridge of Owens Peak (8453').

Based on the expanse of granite seen from Hwy 395, I had visualized the southwest ridge of Owens Peak as a somewhat vegetated but relatively clean  ridge. Wrong! The ridge is a geologically complex mix of fractured metamorphic, metavolcanic and gabbro rock capping the granite of Owens Peak. In most areas the rocky sections of the ridge are bounded by dense brush and pinyon pine.

We pretty much stuck to the crest of ridge on the way up, continuing up and over the steep outcrop just below the summit. Although it was an interesting section to climb, the outcrop was quite loose, and we dropped below it on the descent.

Owens Peak is relatively isolated, and the views from the summit are sweeping. To the north we could see Mt. Whitney, Mt. Langley, Olancha Peak, and the windblown crest of the Sierra between Army and New Army Pass.

Not everyone would see the positive aspects of doing a 10 mile route to a peak that could be done in only 3.5 miles -- or enjoy the ups and downs, and somewhat tedious route-finding along a brushy and crumbling ridge. It's an acquired taste. It was good to share the experience with enthusiastic friends who were still smiling as we jogged down the last yards of trail to the car.

Note: After the Spring snowmelt, it appears there are no natural water sources on the PCT between Walker Pass and Owens Saddle (mile 8.6), or on the ridge.

Mammoth Mountain reports more than a foot of snow fell over the Memorial Day weekend, but that translated to cool, puffy white clouds and blue sky weather in the Los Angeles area, seldom seen this late in May.

Taking advantage of the great weather, on Sunday my son and I ran the Garapito figure eight course in Topanga State Park, doing a slight variation that climbed Eagle Rock, before descending the Garapito Trail.

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 Schwarzenegger's revised state budget, released May 14, rescinded the funding cuts that would have resulted in the closing of 48 California state parks, including Topanga State Park. 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.

View of Grasslands and Talepop trails in Malibu Creek State Park from the Las Virgenes View Trail. The Talepop Trail is on the ridge in the middle distance. The Grasslands Trail runs along the base of the hill.

Along with the Chumash Trail to Rocky Peak Rd., the Secret Trail to Calabasas Peak is one of my favorite local short trail runs. The two mile route to the peak is a mix of single track and dirt road that gains about 750' in elevation.

The trail winds its way through shaded ravines, dense chaparral and sandstone outcrops to Calabasas Peak Motorway. This fire road is followed south about half a mile to a use trail (on the right) that follows a ridge to the summit. It's also possible to continue higher up the road and access the summit from the south. There is a survey marker (actually two) on the summit.

Here's a Google Earth image showing the summit area, and a Google Earth KMZ file of a GPS trace of my route.

Calabasas Peak Motorway continues down to Stunt Rd. and connects to the Stunt High Trail and points beyond. Here's what Calabasas Peak looks like from the Backbone Trail near Saddle Peak.

When considering where I might run this weekend, the words "snow" and "altitude" had a certain appeal. Record high temperatures had been set in the Los Angeles area on Friday and Saturday, and there was little doubt that more temperature records would fall today.

There is yellow, and then there is the YELLOW of the mariposa lily, Calochortus clavatus. Remarkable in its brightness and purity, its yellow is one of the most intense and vibrant concentrations of color I have seen in the chaparral.

It is relatively uncommon, and this is one of a few seen along trails in Rocky Peak Park, and the Simi Hills. Of the varieties listed in the Jepson Manual, this appears most similar to the slender mariposa lily (Calochortus clavatus var. gracilis).

The insect emerging from the flower is a small bee -- probably a sweat bee (Halictidae). These bees were found on several of the mariposa blossoms along the trail. They were usually busy slurping nectar from the gland near the base of each petal, and partially hidden by the club-like hairs that gives the species its name.

From a run earlier this week in Rocky Peak Park.

The greens of Southern California's rain season have given way to the sun burnished colors of Summer.

Increasing temperatures over the next few days should also result in an increase in rattlesnake encounters, such as this one today on the "main drag" at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve).

Note: Jon Sutherland nicknamed the main road that connects the Victory trailhead to Las Virgenes Canyon the "main drag." Jon has run out at Ahmanson for more than 30 years. He is second on the Running Streak List for most consecutive days run. As of March 1, 2008 his streak was 14,160 consecutive days (38 years 281 days)!

Cooper Canyon Falls is in the San Gabriel Mountains on a segment of the PCT that is shared with the Burkhart Trail. It is on one of the main tributaries of Little Rock Creek. Including the cascade at the top, Cooper Canyon Falls drops a total of about 50 ft.

A small patch of snow crunched under foot as I worked my way west along Pleasant View Ridge. Overnight the temperature had dropped below freezing, and careful route-finding was required to work around icy patches of steep snow clinging to the ridge. In other years this might be tedious, but after last year's parched Spring, it was enjoyable to have to wind my way through the maze of rocks, trees, chinquapin and snow.

Most of the snow could be avoided by staying on the sunny side of the ridge. but in a couple of places it was easier to drop down and around large patches of snow on the north side of the ridge. The snow was rock hard, and I wondered if the descent from the highest point along the ridge was going to be a problem. There was little doubt that the north slope of peak 8248 would be snow covered. If the snow extended to the northwest ridge and face, I might have to turn back.

Fortunately, as the photograph above shows, most of the ridge was free of snow, and I was able to continue on the loop. It was great to have snow on the peaks and water in the creeks!

It's been late February since Southern California has had a good soaking rain. As of May 1, the water year rainfall total for Downtown Los Angeles (USC) stands at 13.42 inches. This is 90% of the 1921-2006 average of 14.87 inches. According to the NWS 1921-2006 dataset, the average amount of precipitation in May and June is 0.3 inch and 0.1 inch, respectively. We'll see if we get that much this year!

La Niña appears to be winding down.  In it's April 30 ENSO Wrap-Up, the Australian Bureau of Meteorology characterizes Pacific climate patterns as being generally neutral, "with the majority of indicators returning to near-normal levels." The April 28 ENSO Update from the CPC suggests that La Niña will continue through May-July 2008, but many of the factors discussed indicate general weakening of La Niña. Based on the ONI and MEI, La Nina conditions have existed since about August of 2007.
