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.
Later, I got to see the mine from the Oquirrh Overlook, which you can take a peek at in this blog post.
