High Rock Canyon Wilderness

The Wilderness consists of a large area of broad volcanic uplands dissected by the deeply cut drainages of High Rock, Yellow Rock, Grassy, and Mahogany Canyons. The Applegate-Lassen Emigrant Trail is located in High Rock Canyon, which forms the eastern boundary for the area. Elevations range from 4,900 to 5,800 feet. The main vegetation type is sagebrush, with willows and small stands of chokecherry occurring in the canyons. The canyons are relatively well watered and support meadow complexes and other riparian vegetation. Wildlife in the area includes California bighorn sheep, mule deer, pronghorn antelope, mountain lions, coyotes, and sage grouse. The canyons also provide outstanding habitat for nesting raptors.
