Tower Soudan Underground Mine Takes You Half A Mile Down into the Earth [VIDEO]
The Tower Soudan Underground Mine is located in Northern Minnesota and offers tours of the now closed down underground mine.   This morning during our "Are you smarter than Cathy" trivia game, I asked her how far down the mine shaft went.  The answer was 2,341 feet, which is about 2,160 feet more than she thought.  (She had no idea.)
