Mineview in the Sky Visitor Center, Minnesota

Operated by the Laurentian Chamber of Commerce, this mine overlook was originally established for mine foremen to view the operations below, a network of pits known as the Rouchleau group, a mine complex nearly three miles long and 450 feet deep, which was operated by U.S. Steel and its predecessors until 1977. Now the mines visible from here are closed, and the pits are filled with water, giant unused rectangular lakes. A small gift shop and a broken haul truck are located at the overlook.
