  Fringed Pine Sap - Fruit

Hodgdon Meadow Campground

As I walked through the forest within the Hodgdon Meadows campground, something light in color caught my eye.  I turned and walked towards it, then crouched on my knees to get a closer look. What I saw surprised me. It was a  cream colored plant, totally lacking chlorophyll, pushing through the duff on the forest floor.  This was not an individual, but 6 or 7 little plants, each having a striking resemblance to snow plant in structure (not color, as the Snow Plant is a brilliant shade of red). As I took a closer look, I saw movement. There were 2 large bees crawling from flower to flower, and down into the ground underneath the chunks of forest duff that had been pushed up by the plant during it's emergence. What a delightful scene, that I might have passed right by with out a second glance on my way through the campground. According to Botti in the Illustrated Flora of Yosemite National Park, Fringed Pine Sap is a sparingly occurring saprophyte in Yosemite, which grows at elevations of 1200-2450 meters in the dry forest humus in the mixed conifer and montane zones.

Vernal and Nevada Falls

In Yosemite Valley, dropping over 594-foot Nevada Fall and then 317-foot Vernal Fall, the Merced River creates what is known as the “Giant Staircase.” Such exemplary stair-step river morphology is characterized by a large variability in river movement and flow, from quiet pools to the dramatic drops of the waterfalls themselves.
