About this map

Colorado River whitewater and sheer canyon walls dominate this mid-century survey of northwestern Arizona. The river flows through the formidable Granite Gorge, marked by a series of treacherous obstacles for river runners, including Waterfall Rapids, Devils Slide Rapids, and Last Chance Rapids. To the west, the Hualapai Indian Reservation encompasses high-altitude terrain like Horse Flat, while the eastern side of the river is defined by the massive uplift of the Sanup Plateau within the Lake Mead National Recreation Area.

The landscape is characterized by its dramatic elevation changes, where deep incisions like Burnt Canyon and Surprise Canyon drain into the main river channel. Aside from the occasional Trails shown traversing the plateau, the area remains largely undeveloped, preserving the primitive character of the gorge before modern accessibility. The map provides a precise record of the Hualapai Indian Reservation Boundary as it follows the river's path through the canyon depths.
