1951 Map of Mammoth

About this map

The copper-rich terrain of southern Pinal County is defined by the heavy industrial footprint of the Tiger and Mammoth mining districts. This 1951 survey documents the complex mining landscape just as the San Manuel Copper Mine was emerging as a major regional operation, surrounded by established workings like the Mohawk Mine and the Mammoth Mine. The San Pedro River valley acts as the central artery for the region, where numerous family-owned holdings like Clark Ranch and Sacaton Ranch occupy the fertile ground between the river and the rising Galiuro Mts. Further south, the high country transitions into the Coronado National Forest, where the settlement of Campo Bonito and several historic mines like the Southern Belle Mine sit in the shadows of Rice Pk. The presence of several Cemeteries and storied ranching headquarters like the American Flag Ranch provides a window into the varied layers of settlement in this arid landscape.
