About this map

Mining operations and river valleys dominate this mid-1980s landscape of southern Arizona. The San Pedro River and Gila River corridor serves as the primary artery for settlement, connecting towns like Mammoth and Dudleyville with the industrial hubs of Winkelman and Hayden. Large-scale mineral extraction is a defining characteristic of the era, evidenced by the sprawling San Manuel Mine and prominent Mine Dump labels, alongside older sites such as the Silver Queen Mine and Tiger Mine.

Extensive protected lands and high-relief terrain flank the central valleys, with the Galiuro Mountains housing the Galiuro Wilderness and the Santa Catalina Mountains rising to the south. The Southern Pacific railroad parallels the river systems, illustrating the logistical network required to move ore from the remote canyonlands. To the north, the boundary of the San Carlos Indian Reservation marks a transition from the intense mining activity near Oracle Junction to the more primitive reaches of Aravaipa Canyon.
