About this map

Lake Mead National Recreation Area dominates this desert landscape at the border of Arizona and Nevada, showing the Colorado River as it flows south through Pyramid Canyon. The map records a specific moment in the river's management, noting a maximum elevation of 647 feet. On the eastern shore, the Mohave Crossing (Site) suggests an earlier era of transit across the river before modern water management transformed the corridor.
