Bingham Canyon Copper Mine, Salt Lake City

This is one awesome sight in which ordinary people like me would never get to see very often. This working copper mine is a sight to behold. The size and depth of the open-pit mine is mind-blowing! It would take 2 Sears Tower stacked on top of each other to match the depth of the mine. The giant trucks traversing up and down the mine looked like toy trucks from the observation lookout point. And it's difficult to imagine that a mountain once stood there a century ago. This mine is only half an hour drive from downtown SLC, so this should be everyone's itinerary while visiting Salt Lake City.
