Trail 7778 can be accessed from highway 68 and the Old Kingman Highway. It’s a very scenic ATV Jeep Trail with dramatic rock formations highlighted by twin rocks towering hundreds of feet over the trail into Arizona’s Black Mountains.

The Black Mountains of northwest Arizona are an extensive, mostly linear, north-south 75-mile long mountain range. It forms the north-south border of southwest Mohave County as it borders the eastern shore of the south-flowing Colorado River from Hoover Dam.

The northwest, and parts of the west of the range are located in the Lake Mead National Recreation Area. Three wilderness areas are in the range, and the historic mining site of Oatman, Arizona, 4 miles adjacent and north of Boundary Cone, is nestled in the range’s south between the Mount Nutt and Warm Springs Wildernesses.

The mountain range is generally 10-15 mi wide, narrower in the north, and west of the Detrital Valley northeast. The southern end of the range with the two wilderness areas is a larger block and the Warm Springs Wilderness is made of a mountain section called Black Mesa (western Arizona), separated from the north section by Sitgreaves Pass, on the route to Oatman, AZ.

The high point of the range is Mount Perkins at 5,456 feet, located west of the water divide of the Detrital Valley northeast, and the Sacramento Valley (Arizona) southeast.
