Undisturbed old-growth ponderosa pine, Pinus ponderosa, which is becoming increasingly uncommon in the Sierra, occurs extensively in this area. Approximately three-quarters of the area is covered by a Pinus ponderosa - Chamaebatia foliolosa association. The black oak, Quercus kelloggii, is the second main component of the overstory. In portions, the mountain misery forms nearly 100 percent of the understory. Ceanothus integerrimus and Toxicodendron diversilobum occur here also.
White alder, Alnus rhombifolia, and Darmera peltata are the main components of the streamside vegetation.
On the north-facing slopes there are small areas of mixed conifer forest, with Douglas fir, Pseudotsuga menziesii, dominant, and white fir, Abies concolor, incense cedar, Calocedrus decurrens, in association. On the more rocky sites, canyon live oak, Quercus chrysolepis, and Arctostaphylos mewukka are found.
A total of 153 plant species have been identified here.
Mesozoic granitics underlie the area, and it is drained by several perennial and intermittent streams.
Integrity: The area is virtually undisturbed, It has been proposed as a Research Natural Area.
Use: Research, educational, observational.
