Large-scale industrial copper extraction defines the landscape of the Tonto National Forest in this central Arizona survey. The map centers on the massive Pinto Valley Open Pit Mine and the complex infrastructure of the Inspiration district, including the Inspiration Main Shafts, the Castle Dome Concentrator, and a sprawling Leaching Plant. The sheer volume of material moved is evident in the vast Tailings Pond systems that fill the canyons west of the mining pits.
