About this map

The Colorado River carves through the arid landscape of the Lake Mead National Recreation Area in this mid-century survey of the Arizona-Nevada border. The map documents the flooded reaches of the river canyon, noting a maximum elevation of 647 feet for the reservoir. Along the eastern banks, the landscape is defined by extensive drainage systems like Empire Wash, Portland Wash, and Tyro Wash that cut through the granite uplands.

Evidence of early desert navigation and industry is preserved in labels like Mohave Crossing (Site) and the Gold Chain Mine near the southeastern corner. The rugged western shore is dominated by the Newberry Mountains, where a jeep trail and pipe line indicate limited human infrastructure in the high desert terrain. Local water sources, essential for survival in this environment, are specifically marked at Spring and Calles Spring.
