About this map

The Arizona-Sonora Boundary defines the southern reach of this late-1950s survey, where the international border meets the high desert floor and the sky islands of the Huachuca Mountains and Santa Rita Mountains. This landscape is marked by its complex history of mining and military presence, from the established Fort Huachuca Military Reservation to the rugged extraction sites at Duquesne Mine and Mowry Mine. The Santa Cruz River and San Pedro River valleys provide the primary north-south corridors for transport and settlement, supporting towns like Nogales and the historic community of Tubac.

Remote settlements such as Ruby and Arivaca are positioned within a network of ephemeral washes and vast land reserves, including the Papago Indian Reservation and the Coronado National Forest. The presence of the Southern Pacific Railroad and arterial routes like U.S. Highway 80 highlight the region's role as a critical transit point for trade and travel between the United States and Mexico during the mid-twentieth century.
