1981 Map of Twin Buttes

USGS Topo · Published 1981

About this map

Large-scale copper extraction dominates this Pima County landscape, where the massive excavations of the Mission Mine, Pima Mine, and Twin Buttes Mine have reshaped the desert floor with extensive Mine Dump terraces and sprawling Tailings Ponds. The industrial footprint is supported by the Southern Pacific railroad and specialized infrastructure like the Sierrita Mill and complex conveyor systems.
