Pine Drops

Pine drops (Pterospora andromedea) on the Pacific Crest Trail near Little Jimmy Trail Camp

Pine drops (Pterospora andromedea) and snow plant (Sarcodes sanguinea) are related nonphotosynthetic plants that are found under pine and related trees, primarily in the mountains of the western U.S.

At one time it was believed that these plants were saprophytes, and obtained needed nutrients directly from decaying organic matter in soil. However, research has revealed a more complex parasitic relationship in which the plant obtains carbohydrate from a pine tree, by way of a shared mycorrhizal fungus.

The photograph was taken on the run described in Heat Wave, on July 16, 2006.

Golden Yarrow

Perfectly sized to work the minute central disk flowers of golden yarrow, a tiny insect -- perhaps a species of bee fly -- hovers a few millimeters from the plant.

Perfectly sized to work the minute central disk flowers of golden yarrow, a tiny insect — perhaps a syrphid fly — hovers a few millimeters from the plant, assessing the risk of continuing to feed.

The compound flower head of the golden yarrow (Eriophyllum confertiflorum) is about the size of a green pea (10mm), and the individual disk flowers at its center are about 1/5 as large (2mm).

Lasky Mesa Prickly Pear

Prickly pear on Lasky Mesa in Upper Las Virgenes Canyon Open Space Preserve (formerly Ahmanson Ranch).

This prickly pear on Lasky Mesa appears to have many of the characteristics of the Engelmann prickly-pear, Opuntia engelmannii, but is more likely a cross involving O. engelmannii. One such cross is O. littoralis X (O. engelmannii X O. phaeacantha ) which is referred to as O. ×occidentalis in the Jepson Manual. Here’s a closer view of the stamens and pistil.

Blazing Star

Blazing Star (Mentzelia laevicaulis)

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.

Three Points – Mt. Waterman Loop

Trail sign on the Mt. Waterman Trail in the San Gabriel Mountains.

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.

In a record dry water year, I had been curious to see how the mountains were faring. Although creeks were very low and grasses dry, my impression was that groundwater resources were not quite as bad. The usual springs and seeps still muddied the trail. In 2005 the San Gabriel Mountains were deluged with rain, and in the 2006 the rainfall was nearly normal, so some carryover would be expected.

Update May 27, 2007. My impression of groundwater resources may have been overly optimistic. On a run to Mt. Baden-Powell from Islip Saddle, I stopped by Little Jimmy Spring. It was nearly as low as in late August 2002, when Los Angeles had just experienced its driest water year on record. This year will likely break the 2001-2002 record.

Even so, it was obviously much drier than normal. There were fewer wildflowers, and some young Incense Cedars looked as if they might be stressed. On the plus side, manzanita and currant were blooming in profusion, and perhaps 30-35 scarlet red stalks of snow plant were seen on the loop.

About three miles from Three Points I happened upon another Jeffrey Pine that had been struck by lightning. This strike appeared to more energetic than the bolt that struck the tree on the Baldy North Backbone Trail. The spiral scar was wider and braided at some points, and the strike ignited the tree. Where the Baldy tree was on a sharp ridge crest, this tree was several hundred feet below the main crest in an area where the trail started to work around a projecting ridge.

More about this loop and a Google Earth image of the course can be found in the post Manzanita Morning.
