Kennecott Copper Mine, Utah, USA

Also known as Kennecott Copper Mine, it’s an open-pit mine situated in the southwest of Salt Lake City, Utah. The Bingham Canyon Mine is the largest and deepest man-made excavation in the world: more than 3000 ft deep and 2.75 miles wide! Two Empire State buildings piled up one on top of the other wouldn’t stretch to the top. It is the world’s largest open-pit mine and the 2nd largest copper producer in the U.S. Opened in 1904, the mine has been named a historic landmark later on.
