The Black Mountains, a mid-Miocene formation,^[2] 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.^[3] The range contains deposits of soft manganese oxides/hydroxides.^[4]

History

The Old Spanish National Historic Trail ran down the Virgin Valley-Overton Arm section of the valleys now occupied by Lake Mead. The trail avoided the canyon, at the southwest of the Black Mountains, where the range is separated from Arizona. The trail heading west to Las Vegas, entered the mountains, went southwest of Pyramid Peak, and then skirted Hamblin Mountain to the south, with Pinto and Razorback Ridges north; north of the ridges lies the small, but broad, arid drainage valley, Bitter Springs Valley, which is southeast of, and adjacent the Muddy Mountains.

The trail enters the southern third of the mountain range, and makes the circuit around Hamblin Mountain. The southwestern end of the Black Mountain range, is at Callville Bay, where the trail returned to the bottom land valleys along the Colorado River heading towards Las Vegas.

Access

The northwest, and north of the mountains can be accessed by the paved route, North Shore Road, from Nevada State Route 564, Henderson, Nevada, about 30-mi to the south-southwest.
