Christmas Berry on the Garapito Loop

Photo of the berries of toyon,  Christmas berry (Heteromeles arbutifolia)

A photo of the berries of Toyon (Heteromeles arbutifolia) taken on the Garapito Loop trail run on Thanksgiving Day. Also called Christmas berry, the plant is protected by a California law.

The Garapito Loop is a pleasant 7.5 mile figure eight course that starts at the south end of Reseda Blvd. at Marvin Braude Mulholland Gateway Park, goes up to near Eagle Rock via Fire Road #30 and Eagle Rock Fire Road, and then returns via the Garapito and Bent Arrow Trails. Here’s a Google Earth image of a GPS trace of the route and a 3D, interactive view of a slightly longer variation of the loop that visits Eagle Rock.

Milk Thistle Seed Heads

Milk Thistle (Silybum marianum) seed heads.

A native of the Mediterranean, Milk Thistle is an invasive weed that appears to be increasingly profuse in roadside areas of Upper Las Virgenes Canyon Open Space Preserve. Generally considered detrimental in the wild, the plant has been used medicinally for at least 2000 years, and is cultivated in Texas, Canada and Argentina.

According to the Washington State Noxious Weed Control Board, Milk Thistle (Silybum marianum) produces about 190 seeds per flower, and over 6000 seeds per plant. Dense stands are reported to produce 1.4 million viable seeds and four tons of vegetation per acre! Here is a closer look at an individual Milk Thistle seed.

This photograph was taken on a run at Ahmanson Ranch on July 13, 2006. The posting Convoluted includes a photograph of the white-veined leaf, and a photo of a dense stand of Milk Thistle in Las Virgenes Canyon. Additional information regarding Milk Thistle, including its history, laboratory studies, clinical trials, and adverse effects can be found in the National Cancer Institute’s Milk Thistle (PDQ®).

Heat Wave

As I turned into the Vincent Gap parking lot and pulled to a stop, a few sprinkles of rain dotted my windshield. Opening the car door, I wanted to close it again. It was 7:30 in the morning and the temperature was already nearing 70 degrees. It shouldn’t have been a surprise. The previous two days the National Weather Service office had issued an “excessive heat warning” for much of the Los Angeles area, including the lower elevations of the mountains.

Angeles Crest Highway was closed 2.6 miles west of Islip Saddle, so my plan was to do the Islip Saddle – South Fork – Mt. Baden-Powell loop from the Vincent Gap side. (Update May 21, 2009. Angeles Crest Highway has since been re-opened to Islip Saddle, and through to Wrightwood.) This difficult 23 mile loop, and some of its logistical issues, were described in the posting Complications.  The day was really too warm to be doing this route, but with a chance of thunderstorms in the forecast maybe some clouds would help keep temps in check. I’d run at least to Little Jimmy Spring. If it was too hot, I could always head back.

It didn’t take long for the clouds that had spritzed my windshield to move off to the west. Except for a smoky haze from the Sawtooth Fire, mostly clear skies prevailed as I worked up the numerous switchbacks of Mt. Baden-Powell.  Near the summit of of the peak, I paused for a moment to admire the Wally Waldron Tree. At an elevation and in an environment similar to the 4000+ yr. old White Mountain Bristlecone Pines, this gnarled and weather-beaten Limber Pine is estimated to be 1500 years old. Clearly ancient, it has survived wind and weather too extreme to imagine. According to the Forest Service, some Limber Pines in this area may be as much as 2000 years old. Extended longevity doesn’t appear to be limited to Limber and Lodgepole pines; a stunted White Fir near the summit also looks unusually old.

Down from the summit, and back on the Pacific Crest Trail, the running along the ridge was outstanding. Near Mt. Burnham, I stopped to take a few photographs, and watch a bumblebee working through a batch of Grinnell’s Penstemon (Penstemon grinnellii). The throat of this particularly bulbous penstemon perfectly accommodates the bumblebee, and perhaps is an example of a flower adapting to a preferred pollinator. Continuing along the crest, between Throop Peak and Mt. Hawkins, red accents among the rocks marked patches of Bridge’s Penstemon (Penstemon rostriflorus). From time to time, sparse clouds masked the sun, but as I descended toward Windy Gap, the temperature climbed inevitably higher.

One of the pros of doing the loop from Vincent Gap is that it is great to have fresh legs for the exceptional trail running down to Islip Saddle. Except for a short climb over the shoulder of Throop Peak, the running is generally downhill from the summit of Baden-Powell  (9399′), all the way to South Fork Campground (4560′). This is a distance of over 13 miles, with an elevation loss of nearly 5000′. The major con is having to do the lowest elevation segment of the loop, and the climb back to Vincent Gap (6565′), during a warmer time of the day.

Aside from the heat, another concern had been nagging at me. What if the trail was impassable? This wasn’t heat induced paranoia. Last year, several sections of the South Fork trail were buried in small rock slides, and a couple of places where the Manzanita Trail crossed steep erosion gullies were in very bad shape. A Winter had passed, and who knew what recent thunderstorms had done to the trails?

Switchbacking down to Little Jimmy Spring, I had already decided to continue to Islip Saddle. In the battle of “do, or do not” I knew that once at Islip Saddle, “do” would win again. Maybe some clouds would help me on my way…

Epilogue: In sun-baked South Fork canyon, even the downhill was difficult, but the rock slide plagued trail was still passable. Some clouds provided temporary relief at South Fork Campground, but didn’t last. The damage to the Manzanita Trail was worse than last year, but with care I was able to get through. In nearby Valyermo, midday temps reached over 100°F. Here’s a Google Earth image and Google Earth KMZ file of a GPS trace of the route, and a Forest Service diagram of area trails that’s at Vincent Gap.

Lemon Lily

Lemon Lily (Lilium parryi)

If somehow you were to miss the bright yellow of this lily amid the greens of a mountain meadow, its arresting fragrance would certainly draw your attention.

In terms of its habitat niche, the Lemon Lily (Lilium parryi) is a higher elevation analogue to the Humboldt Lily, occurring in meadows and near seeps and springs in pine and fir forests up to an elevation of about 9000 feet.

The Lemon Lily is listed by the California Native Plant Society as being rare, threatened, or endangered.

The photograph was taken on the Three Points – Cooper Canyon – Mt. Waterman loop described in Manzanita Morning.

Seeing Red

Indian Paintbrush (Castilleja affinis) in Cheeseboro Canyon.

In this case, Indian Paintbrush (prob. Castilleja affinis), Scarlet LarkSpur (Delphinium cardinale), and Indian Pink (Silene laciniata) in the Cheeseboro Canyon area of Southern California.

As is the case with many wildfires, one of the side effects of the 2005 Topanga Fire has been to promote a population explosion in many species of wildflowers. Scarlet Larkspur has been especially prevalent in some areas, such as upper Cheeseboro Canyon.

These photos were taken on a run to Simi Peak from the Las Virgenes Rd. trailhead of the Upper Las Virgenes Open Space Preserve on June 11, 2006. I like to go out via upper Las Virgenes Canyon, and come back through Cheeseboro Canyon. This variation is about 16 miles, with an elevation gain and loss of about 2000 ft. The run can be extended to about 21 miles by starting at El Scorpion Park, near Vanowen and Valley Circle. Following are links to trail maps for Upper Las Virgenes Canyon Open Space Preserve and Cheeseboro/Palo Comado Canyons.

Plummer’s Mariposa Lily

Plummer's Mariposa Lily (Calochortus plummerae).

When the hills and valleys of Southern California turn golden brown, and temperatures reach into the nineties or beyond, mixed in among the desiccated grasses, enjoying the heat and the sun, may be the delicate pink to purple of a Plummer’s Mariposa Lily (Calochortus plummerae).

Previously listed by the California Native Plant Society as being rare, threatened, or endangered, the Plummer’s Mariposa is now listed as uncommon and fairly endangered in California.

Note: Plummer’s Mariposa Lily (Calochortus plummerae) and Foothill Mariposa Lily (Calochortus weedii var. intermedius) are closely related species that have intersecting ranges and similar characteristics. C. plummerae is more frequently reported in Los Angeles County.
