We followed the signs for the visitor center, and upon arriving, found this amazing sight in front of us.
This copper mine has produced more copper than any other mine in history--more than 18.1 million tons. It's about 2 3/4 miles across at the top and 3/4 of a mile deep. Mining started in Bingham Canyon in 1863, with engineers soon after recommending a revolutionary way of mining the ore, using a process called open-pit mining and then refining the ore on an industrial scale.
To move all this ore and overburden, the mine has 70 giant haulage trucks. You can see the size of them above compared to the crew-cab pickup that is also traveling on the road. Each haulage truck carries 255 to 320 tons of material in each trip at an average speed of 13 mph.
The visitor center had a nice movie and well-thought-out displays. The kids especially liked the models of the mining equipment. I really liked looking at the historic photos and how much things have changed. We also learned about different uses for copper, such as in plumbing, computers, and telephones. It turns out that each person in the U.S. uses about 30 pounds of copper a year. It was a thought-provoking trip, and I'm really glad we went and took a look.
Later, I got to see the mine from the Oquirrh Overlook, which you can take a peek at in this blog post.
