In December 2005, in order to protect critical habitat of the mountain yellow-legged frog, the Forest Service closed approximately 1,000 acres in the upper Little Rock Creek drainage in the San Gabriel Mountains. The closed area includes Williamson Rock, and the Pacific Crest Trail between Eagle's Roost and the Burkhart Trail. Angeles Crest Highway (SR2) was also closed at Cedar Springs, just west of Eagles Roost, but has since been re-opened to Islip Saddle. On May 27, 2007, it looked like the road past Islip was being resurfaced.

On May 8, 2007, Angeles National Forest issued a press release and scoping letter, proposing to "develop a trail that will protect the mountain yellow-legged frog and its critical habitat, while also providing access to the Williamson Rock," and has requested that all interested parties provide written comments by June 6, 2007.

Williamson Rock is an area of exceptional scenic and recreational value. Because of its proximity to Los Angeles and its suburbs, variety of climbing routes, scenic beauty, and moderate sunmmertime temperatures, it is one of the most popular rock climbing areas in Southern California. Hopefully the Forest Service will move forward with its proposal and re-open this key recreational resource.

For more information and sample comment letters, see the Friends of Williamson Rock blog.

The photograph of Williamson Rock was taken on the PCT while doing the run Pleasant View Ridge on July 2, 2006.

Rose snapdragon (Antirrhinum multiflorum) at Sage Ranch Park. From a run on May 14, 2007.

Located near Mammoth Mountain, San Joaquin Ridge extends from Minaret Summit (9265') north about six miles to San Joaquin Mountain (11,601'). Views from this ridge are legend, with broad vistas that include Mt. Morrison, Red Slate, Mammoth Mountain, the Minarets and Ritter & Banner, Mono Lake, and much more. In good weather it is an awe inspiring locale in which to hike, ski or run.

This day, the conditions for running the ridge are ideal. In the wake of a weak weather system, skies are mostly clear, and a cool breeze reduces the heat of the harsh sun, producing a welcome warmth. Winter snow is already receding from the ridge crest, allowing a choice of routes over, or around, remnant drifts and cornices.

Returning from a high point a few miles distant, bounding strides lengthen, and I seem to soar down the ridge, weaving among the stunted pines, glissading across bands of snow, caressing the wind and flying up or down slopes with equal ease. It has become a run that defines the root experience of trail running and the rewards of being in the mountains. There is freedom of motion -- and emotion -- in every stride.

Ahead of me, a pair of ravens turn and the Sun glistens from back to wing. Individual feathers ruffle as wings are adjusted to increase lift, and turns are tightened. Soon we are soaring high above the Sierra, and all things seem possible.

From a run at Upper Las Virgenes Canyon Open Space Preserve (formerly Ahmanson Ranch) on May 15, 2007.

Blazing star,
Dancing shadows,
It looms above...

The Baldy Peaks 50K (currently in hiatus) is without a doubt the most challenging 50K I've done. This race climbs to the summit of Mt. Baldy twice, once from the village and once from Manker Flats. And after climbing Baldy twice, you get to amble over to Thunder Mountain as well. The total elevation gain (and loss) is reported to be 10,775 ft.

Race organizers asked endorphin influenced runners to write a poem on the second ascent of the peak.

This particular Blazing Star (Mentzelia laevicaulis) was on the Manzanita Trail, between South Fork Campground and Vincent Gap. In the Baldy Peaks race they were along the service road between the Notch and Manker Flats.

From the Three Points - Mt. Waterman trail run on Sunday.

Five miles of (mostly) downhill to go. Running through an old growth forest of Jeffrey Pine, Sugar Pine and Incense Cedar, I relished being on a pine needle covered trail at 7000 ft. in the San Gabriel Mountains.

From the rocky summit of Castle Peak I traced the course of Bell Creek into the San Fernando Valley, imagining the broad valley as it might have been a few hundred years before.

Blue oak (Quercus douglasii) is a characteristic oak of the lower elevations of the Sierra foothills and coastal mountains, its range essentially encircling California's Central Valley.

Based on its reported range, Upper Las Virgenes Canyon Open Space Preserve (formerly Ahmanson Ranch) contains one of the southernmost populations of blue oak within its range. However, the predominate deciduous oak in the area is valley oak (Quercus lobata), and occurrences of blue oak appear to be rare. Regional climate modeling suggests that over the next century the range of blue oak could shift northward and diminish to nearly 60% of its current range.

Blue oak is reported to hybridize with valley oak, however a 2005 study suggests hybrids of these species may be more rare than generally accepted.

The photograph of the leaves of a blue oak was taken on a run along East Las Virgenes Canyon to Lasky Mesa on April 24, 2007. A valley oak immediately adjacent to this blue oak was killed in the 2005 Topanga Fire.

One of the best indicators of seasonal rainfall I've found in the oak woodland and chaparral areas of Southern California in which I run is Elegant Clarkia (Clarkia unguiculata). In a wet year it can grow more than 6 ft. tall. This year it is the shortest I've ever observed -- about 5 inches in this photo taken near Lasky Mesa.

Running down the Silver Moccasin Trail from Shortcut Saddle to West Fork a couple of weeks ago, I mentioned to my running partner that a few years before, I had carried my whitewater kayak down the trail. Around 1995, Gary Gunder and I started exploring the creeks and rivers of Southern California, looking for hidden gems that rarely - if ever - had been paddled. Kayaking these streams has been an incredible experience, and has enabled us to see some of the wildest and most beautiful places in the mountains of Southern California.

A closer look at the feathery blossoms of the holly-leaved cherry (Prunus ilicifolia) reveal a peculiar flower whose many stamens resemble the tentacles of a sea anemone.

Holly-leaved cherry is a member of the genus Prunus -- the same as apricots, peaches, plums and cherries. As is the case with other species in this genus, the seed and leaves may contain hydrogen cyanide. It produces a small, thin-fleshed fruit favored by coyotes.

The photograph was taken on the slopes of Rivas Canyon near Will Rogers State Historic Park, while doing the route described in the post Will Rogers - Temescal Loop. Once again the weather for this (approximately) 21.5 mile loop was post-card perfect. A Google Earth image of a GPS trace of the route is available in the earlier post.
