About this map

The Colorado River carves a deep path through the Eldorado Mountains in this late 1950s survey of the Arizona-Nevada border. This stretch of the river, within the Lake Mead National Recreation Area, shows a transition from the narrow confines of White Rock Canyon to the broader Detrital Valley. The settlement at Willow Beach serves as a focal point for activity, featuring a State Fish Hatchery, a Ranger Sta, and a Gaging Sta.

Industry and transport are marked by the Two Bs Mine on Black Ridge and various Jeep Trails navigating the desert terrain. Significant landmarks like Mount Wilson, Housholder Pass, and the distinctive Malpais Flattop Mesa provide essential orientation in this desert landscape. The map also records numerous river features such as Ringbolt Rapids and Roaring Rapids, noting the character of the river before modern water management further altered the flow.
