The Nopah Range is rugged and shaded with color, its sedimentary rocks capping at 4,200 feet. Gently rolling alluvial slopes or bajadas on the east and west sweep up to the south end of the rugged folds of the Nopah Mountain Range. Desert bighorn sheep make their home in the northern portion of the mountain range year-round. The eastern part of this wilderness includes portions of California Valley.
Vegetation is sparse, but prairie falcons have been seen hunting over most of the lowland areas.
The environment here is known to support habitat for the ivory-spined agave plant, although no specimens have actually been collected from within the wilderness. Wild horses and burros also may be seen in the area. Access this wilderness from State Highway 127 via the 010 Spanish Trail Highway. Private lands may lie within the wilderness area. Please respect the landowner and do not use these lands without permission.
