Perus Toquepala copper mine#
At the surface, the open pit is 2.5 km (1.5 mi) across, and it descends more than 700 m (2,300 ft) into the earth. A dark line on the wall of the pit is the main access road to the bottom. Spoil dumps of material mined from the pit are arranged in tiers along the northwest lip of the pit.
Numerous angular leaching fields appear lower right, and the railroad to the coast is a line that exits the image center left. The railroad was built to export Toquepalas copper and connects the coastal port of Ilo, 95 km (60 mi) to the southwest.
