Kennecott Utah Copper-Bingham Canyon Mine – Herriman, Utah - Atlas Obscura

Kennecott Utah Copper-Bingham Canyon Mine

Largest man-made excavation on earth! 


Standing at the overlook within the Bingham Canyon Mine, you can see, hear, and feel the breathtaking and awesome magnitude of the largest man-made excavation on earth. While you watch the action in the mine, a descriptive narration recorded in several languages explains the operations.

From the overlook, you can watch 240 and 320 ton capacity haulage trucks deliver copper ore to the in-pit crusher, where the material is reduced to the size of soccer balls before being loaded onto a five-mile conveyor that carries the ore to the Copperton Concentrator. Some curious facts about the mine include:

*Kennecott’s Bingham Canyon Mine has produced more copper than any mine in history—about 18.1 million tons.

*The mine is 2-3/4 miles across at the top and 3/4 of a mile deep. You could stack two Sears Towers (now known as the Willis Building) on top of each other and still not reach the top of the mine.

*The mine is so big, it can be seen by the space shuttle astronauts as they pass over the United States.

*If you stretched out all the roads in the open pit mine, you’d have 500 miles of roadway—enough to reach from Salt Lake City to Denver.

Update: As of summer 2019, the visitors center and organized tours are back fully operational.
