A portion of the Ibex Hills and parts of the Dublin Hills and Black Mountains are preserved in this Wilderness. The Ibex Hills form a craggy, north-south divide between the alluvial slopes of Greenwater Valley on the east and the raggedy Black Mountains on the west. From a low of about 3,000 feet, elevations climb to 4,752 feet on the summit of Ibex Peak on the western boundary. Horizontal rock layers in the mountains are highlighted with distinctive bright red, yellow, and black hues. The ruins of at least a half-dozen old talc mines are scattered forlornly throughout the area, and a non-Wilderness road corridor extends from the southeast to the major mining region. Visitors have spotted desert bighorn sheep frolicking about, and can occasionally draw water from several springs. Death Valley National Park lies to the west and south.
