Black Mountain stands at 3,941 feet, a mesa rising above an expanse of desolate, ancient lava flows. The mountain lies in the northwest corner of the Wilderness, and from the summit, the area drops in elevation to 2,080 feet. You'll find a deposit of fine-grained sand in the southeast corner, and not much else other than an occasional golden eagle or prairie falcon circling in search of food. There are no trails, but a spring exists near Opal Mountain. A significant amount of privately owned acreage exists within the area that should not be used without permission.
