Bingham Canyon Copper Mine

In Bingham Canyon, 25mi/40km southwest of Salt Lake City near the township of Copperton, is the world's largest opencast copper mine, which is also the largest man-made hole in the earth's surface, almost 2.5mi/4km in diameter and over 2950ft/900m deep. From the Visitor Center (informative displays and video shows on copper-mining) there is a good view into the terraced interior of the mine.

A visit to the mine includes watching large trucks taking copper ore to the crusher where they are reduced in size and put on a five-mile conveyor belt.
