2011 Map of Dome Rock Mountains SW

About this map

Yuma Proving Ground occupies a significant portion of this landscape in La Paz County, highlighting the region's long-standing connection to military testing and desert operations. The terrain is defined by an intricate network of drainage systems that flow through the arid basin, including the prominent Ehrenberg Wash and the branching paths of Lake Wash and Limekiln Wash. These ephemeral watercourses illustrate the natural hydrological patterns of the Dome Rock Mountains' southwestern slopes. Overland travel in this desert environment is facilitated by historic desert routes such as Cibola Rd and Tom Wells Rd, which intersect the dry beds of La Paz Arroyo and Weaver Wash. The map documents a sparsely settled but strategically important corner of the Arizona desert, where rugged topography meets federal military land use.
