About this map

Tiger and Mammoth anchor this 1940s landscape, illustrating a period of intense industrial activity in Pinal County. The map details a sophisticated mining infrastructure, most notably around the San Manuel Copper Mine and Mammoth Mine. This extraction economy is further evidenced by a specialized built environment including a Power House, Cooling Tower, and extensive Tailings Pond facilities. These industrial landmarks are concentrated near Red Hill, where the Mohawk Mine and Ford Mine also appear.

Water management and local terrain are central to the settlement pattern, with numerous washes like Smelter Wash and Tucson Wash draining toward the San Pedro River. Beyond the mines, the map records more permanent community markers, such as the local Cemeteries near Mammoth and several remote wells and tanks scattered across the Black Hills. A prominent Telephone Line serves as a vital communication link, connecting the residential hubs to the productive mining sites.
