世界最大露天銅礦Bingham Open Pit Mine.

Here's some photos of the world's biggest open pit copper mine (as claimed). The one with the sign that says "wild horse and burro center" is the entrance to the east trail.

Below are old photos taken back in 2005. Copper Mine from the west trail.

This is the view from the south "rim"--you will find this photo in most publications of the Bingham Open Pit Mine.
