About this map

Lake Mead National Recreation Area occupies the southern portion of this landscape, where the arid basin meets the distinct geological formations of the Mojave Desert. The map reveals a sophisticated network of desert hydrology, centered on a series of critical water sources such as Black Willow Spring, Little Arizona Spring, and Tassi Spring. These perennial points were historically vital for livestock and travelers moving through the high desert of northwestern Arizona.

Topographical interest is concentrated in the namesake Gyp Hills and striking natural features like The Cockscomb and The Box. These landforms, along with the drainage systems of Grand Wash and Pigeon Wash, provide a clear picture of the region's complex drainage and erosion patterns. Sparse infrastructure is represented by Co HWY 111 and Co HWY 113, which trace the periphery of this remote desert territory.
