A large open pit iron mine that was worked by Inland Steel from 1969-1986 (in Sec 15 T21N R3W). It exploited highly metamorphosed Archean age banded iron formation, covered by Cambrian sandstone and Pleistocene glacial drift.

The mine is now essentially reclaimed, although dump piles still exist and large boulders from the mine decorate the landscape. The area is now protected as Wazee Lake Recreation Area, a Jackson County park. The lake is the filled-in open pit. It is popular with scuba divers as it is the deepest water body in Wisconsin. Glacial and disaggregated Cambrian sandstone from the mining operation make a nice beach at the south-east end of the lake.
