Easily rolling alluvial slopes (bajadas) from the east and west sweep gently up to the south end of the rugged folds of the Nopah Mountain Range in the South Nopah Range Wilderness. Shaded with soft colors, the Nopah Range is composed of sedimentary rocks capped at about 4,200 feet. The California Valley extends into the eastern Wilderness. Desert bighorn sheep may be seen here, especially in the northern portion, along with wild horses and wild burros. A few prairie falcons have been spotted hunting over the low desert regions. Vegetation is sparse but the environment is known to support the ivory-spined agave plant. You should see evidence of old mining activity in the southern portion. You won't find any trails or much water to drink. Just across the Old Spanish Trail on the north end lies Nopah Range Wilderness.
