Black Mountains (Nevada)

Black Mountains (Nevada)

The Black Mountains, a mid-Miocene formation, in Nevada are a series of rugged, arid rocky volcanic mountains ranging in elevations to 3310 ft. The range lies on the north shore of Lake Mead, at the southwest corner of the Overton Arm, about 25 mi south of Overton, Nevada.

The Black Mountains are mostly within the Lake Mead National Recreation Area, with a small valley bordering north, the Bitter Spring Valley at the southeast of the arid Muddy Mountains

Deep canyons and washes that flow southeast into the Overton Arm of Lake Mead cut into the mountain range. The range contains deposits of soft manganese oxides/hydroxides.
