About this map

The industrial and natural landscapes of the Pinal County region are defined by the convergence of the Gila River and San Pedro River. By the mid-1980s, the copper mining legacy of the area is centered on the massive San Manuel Mine and the accompanying San Manuel Arizona RR, which snakes through the desert terrain. To the north, the confluence of the rivers near Winkelman and Hayden anchors a corridor of settlement that includes Dudleyville.

Remote reaches of the Galiuro Mountains and the Santa Teresa Mountains provide a backdrop to more isolated operations like the Silver Queen Mine and Grand Prize Mine. The map reveals the stark topography of the Aravaipa Canyon and the Galiuro Wilderness, contrasting the deep desert washes such as Mammoth Wash with the established communities of Oracle and Catalina near the base of the Santa Catalina Mountains.
