1959 Map of Ringbolt Rapids

About this map

Black Canyon carves a dramatic corridor through this 1959 survey, marking the jagged boundary between Arizona and Nevada. The Colorado River flows through the center of the sheet, characterized by a series of treacherous water features including Ringbolt Rapids, Horseshoe Rapids, and Cranes Nest Rapids. These names reflect the difficult navigation of the river before its character was further altered by regional water management projects. Along the banks, several Hot Springs and geological features like White Rock Canyon punctuate the arid landscape of the Lake Mead National Recreation Area. Human activity is represented by infrastructure such as a Gaging Station, a Ranger Station, and the State Fish Hatchery near the southern end of the canyon. The Eldorado Mountains dominate the western terrain, crisscrossed by a network of Jeep Trails and footpaths.
