About this map

The Desert Range and the Black Hills define the rugged topography of this landscape on the boundary of the National Wildlife Range. The eastern portion is dominated by the steep ridges of the Desert Range, while the west descends into the Three Lakes Valley and a broad Depression. This area is characterized by a mix of wildlife conservation and intensive military use, as evidenced by the presence of the Nellis Air Force Range boundary.

Remote infrastructure serves both past and present functions across the desert floor. An Old Railroad Grade cuts across the southwestern corner, marking a legacy of former transport corridors through this arid terrain. Modern military operations are visible through specialized labels like Target Area, Protective Dome, and a Borrow Pit. Navigation across the territory relies on unpaved routes such as Alamo Road and Cow Camp Road, which connect the valley to the higher elevations.
