Here is some links to the Mine collapse in Utah. Pretty good pictures in some of them. The mine is huge and the slide area is pretty big as well. It's going to take a long time to get this place back up and running. From what I read this mine is responsible for about 10% of the US silver mining capacity and other metals as well. I don't know much about mining, but it sounds like a large variety of stuff comes from this one.
