1967 Map of Travertine Rapids

About this map

The Lower Colorado River cuts through the profound depths of the Granite Gorge in this 1960s survey, marking a stark geological and political boundary between the Shivwits Plateau and the Hualapai Indian Reservation. The river corridor is defined by its treacherous technical features, including Two Hundred and Thirtytwo Mile Rapids, Travertine Rapids, and Diamond Creek Rapids. This reach of the canyon is also noted for Travertine Falls, where mineral-rich waters have shaped the landscape. High above the river, the Lake Mead National Recreation Area extends across the plateau, with Kelly Point serving as a prominent overlook. The map illustrates the intense topographical relief of the region, from the high desert of the plateau down through the steep walls of Two Hundred and Twentymile Canyon to the river floor.
