Black Mountain Wilderness

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. Golden eagles and prairie falcons have been seen foraging in this area, which is also known for its occasional display of spring flowers. There are no trails, but a spring exists near Opal Mountain. If you travel to the southeast corner of the Wilderness you will find a deposit of fine-grained sand. A significant amount of privately owned acreage exists within the area that should not be used without permission.
