1971 Map of Gyp Hills

About this map

Gyp Hills dominate this arid landscape in Mohave County, where the desert topography is defined by a network of drainage washes and isolated water sources. As part of the Lake Mead National Recreation Area, the map documents the transition from the high desert to the canyon lands. Settled areas are sparse, represented by locations like Seven Springs Ranch and Tassi Ranch, which likely relied on the cluster of named springs including Black Willow Spring, Tassi Spring, and Grapevine Spring.
