About this map

Ajo stands as the primary hub in this mid-century western Arizona landscape, surrounded by extensive mining activity and vast conservation areas including Organ Pipe Cactus National Monument and the Cabeza Prieta Game Range. The map illustrates a complex network of desert survival and transportation, where the Gila River corridor to the north facilitates several settlements like Gila Bend and Theba along the Southern Pacific Railroad.

South of the rail line, the terrain is defined by the Mohawk Mountains and the Growler Mountains, framing the San Cristobal Valley and Growler Valley. Human presence in this arid region is marked by isolated landmarks such as O'Neills Grave and the Devil's Highway, alongside military installations like the Dateland Air Force Auxiliary Field. The eastern portion is dominated by the Papago Indian Reservation, showing traditional village sites such as Gu Achi (Santa Rosa) and Sikul Himatk, while the copper-rich hills near Ajo show the footprints of industrial mining.
