1981 Map of Tubac

About this map

The Santa Cruz River valley serves as a central corridor for settlement and transit in this southern Arizona landscape. Anchored by the historic Tubac area and the Tumacacori National Monument, the map documents a region where Spanish colonial history meets 20th-century ranching and infrastructure. The Southern Pacific railroad parallels the river, connecting smaller locales like Carmen and Calabasas. Away from the valley floor, the terrain rises into the Tumacacori Mountains and the Coronado National Forest, where a network of canyons such as Aliso Canyon and Rock Corral Canyon define the watershed. Notable for local history researchers are the numerous named wells and ranch sites, including the Kenyon Ranch and Rock Corral Ranch, as well as unique landmarks like the CCC Dam and the Camp Loco ruins tucked into the western ridges.
