1959 Map of Black Canyon

USGS Topo · Published 1966

About this map

The Colorado River carves through the heart of this landscape, separating the Black Mountains of Arizona from the Eldorado Mountains of Nevada. This mid-century survey captures the river's character before major modern alterations, highlighting a series of formidable whitewater features including Ringbolt Rapids, Cranes Nest Rapids, and Roaring Rapids. The settlement at Willow Beach serves as a focal point for activity along the water, housing a Ranger Station and the State Fish Hatchery. Away from the river corridor, the terrain transitions into the desolate beauty of Detrital Valley. The map also documents isolated industry and navigation aids such as the Two Bs Mine tucked into the Black Ridge and a Gaging Station perched above Indian Rapids, reflecting the dual priorities of mineral extraction and water management in this arid borderland.
