The Bingham Canyon copper mine is located in the Oakle Mountains near Salt Lake City, Utah. The mine is 1200 meters deep, 4,000 meters wide, and has an area of 7.7 square kilometers. It is one of the artificial landscapes visible in outer space, and its size is imaginable. When it was mined in 1906, it was still a mountain. Over 100 years, the 6 billion tons of ore dug up from here have not only produced a large amount of copper, but also a considerable amount of gold, silver and platinum. Now, the original mountain is gone, replaced by a huge spiral pit, and the excavated ore residue pile into a rolling man-made loess plateau. It is still expanding in size. The landslide in 2013 has stopped opening to the outside world.
