However, I have been to the Soudan mine. I went there once with a friend on a camping trip. It was a blast! The site is run by a the Minnesota State Park Service. We rode down into the mine using the elevator that the miners used. It was scary fun. Completely dark, loud and seemingly very fast, the elevator plunged us straight down into the mine.
Visitors are lowered in an 80-year-old electric mine hoist to level 27, the mine's lowest level at 2,341 feet (713.5 m) below ground.
It was like a ride at an amusement park. There we saw a gigantic cave where the miners had dug out the valuable hematite ore. Our tour guide was excellent, telling us fascinating stories about the history of the mine and the mining process.
If you are ever up there in northern Minnesota, be sure to visit. You won't be disappointed.
