About this map

The rugged international border region of Pima and Santa Cruz counties is defined here by a dense concentration of late-20th-century mining and ranching history. Just north of the United States-Mexico border, the landscape is punctuated by numerous extraction sites such as the Yellow Jacket Mine, the Austerlitz Mine, and the Saint Christopher Mine. The presence of an Old Mill Site and the El Oro Cemetery near the El Oro Mine suggests a localized industrial node that supported workers in this canyon-heavy terrain.

Ranching life is represented by the Oro Blanco Ranch and Tres Bellotas Ranch, while many tanks like the Cemetery Tank and Mojonera Tank illustrate the critical water management needed for survival in the Coronado National Forest. This 1970s survey captures a landscape where industry and habitation were dictated by the deep cuts of Warsaw Canyon and Alamo Canyon, with remote traces of the past visible at Casa Piedra Ruins.
