About this map

Industrial expansion across the Mule Mountains characterizes this 1920s tactical survey, where the copper mining complex surrounding Bisbee reaches deep into the surrounding canyons. A dense network of mining infrastructure is visible, including the Junction Mine, Denn Mine, and the Phelps Dodge Corp Concentrator. These operations are supported by worker settlements such as Lowell, Warren, and the descriptive Tin Town.

The map details a landscape of international transition, spanning the United States Mexico boundary at Naco. This border zone includes Camp U.S. Troops and a Mex Custom House, while the Southern Pacific R.R. of Mexico extends southward from the line. Numerous family ranches, including Armstrong's Ranch and Forrest's Ranch, dot the plains between the mountain ranges and the Sulphur Spring Valley, illustrating the dual economy of mining and ranching in this high-desert environment.
