About this map

Turtleback Mountain and the southern reaches of the Gila Bend Mountains dominate this arid landscape in Yuma County. Surveyed in the mid-1960s, the terrain is defined by a network of ephemeral drainage systems including Deadman Wash, Nottbusch Wash, and Red Raven Wash, which carve through the desert towards the Hyder Valley. Human presence is minimal, marked primarily by the Harquahala Palomas Road and various rugged tracks labeled as Jeep Trail.

The map reveals the vital importance of water infrastructure in this remote environment, noting specific points of interest such as Dry Well and Corral Well. To the northeast, the Picacho Hills provide additional topographic relief. This sheet is particularly useful for those tracing old transport routes through the Sonoran Desert before modern development, showing the exact paths of desert roads and trails as they existed decades ago.
