About this map

The Colorado River carves a deep path through the canyonlands of northwest Arizona in this 1960s topographic survey. The landscape is defined by the convergence of major federal jurisdictions, where the Grand Canyon National Park meets the Lake Mead National Recreation Area and the Hualapai Indian Reservation. The river itself features the turbulent Whitmore Rapids, a significant point of navigation and terrain change within the gorge.

Geological features dominate the northern portions of the map, specifically the Lava Area and the high peaks of the Uinkaret Mountains. Evidence of human presence and survival in this arid environment appears through isolated labels such as Paws Pocket, The Cove, and the vital Cane Spring. Large-scale natural drainage systems like Whitmore Wash cut across the lava-strewn plateaus toward the canyon floor, illustrating the complex erosional history of the Mohave County region.
