About this map

The Colorado River carves a deep path through northwestern Arizona on this 1967 survey, serving as a political and natural boundary between the Grand Canyon National Park and the Hualapai Indian Reservation. This map illustrates the convergence of major federal and tribal lands, including the eastern reaches of the Lake Mead National Recreation Area. The landscape is defined by its dramatic relief and hydrography, marked by significant river features like the Two Hundred and Fivemile Rapids.

Detailed drainage patterns are visible along the steep canyon walls, where named tributaries such as Hundred and Ninetyfour Mile Canyon and Two Hundred and Fivemile Creek meet the river. Notable landmarks include the distinctive peak of Mollies Nipple and the winding course of Spring Canyon, while the border between Mohave and Coconino counties is meticulously plotted as it follows the river's center.
