Boasting amazing minerals from the Great Lakes Region and around the world, the A. E. Seaman Mineral Museum is a Heritage Site of Keweenaw National Historical Park. The facility features the world’s best collection of Michigan minerals, exhibits from the University of Michigan mineral collection, a fluorescent mineral exhibit, and the copper Pavilion, showcasing a world record 17 ton native copper slab.
The museum sits near four old mining shafts on the Mabbs Vein, mined by the Isle Royale Mining Company, dating back to the 1860s. One shaft was rediscovered during construction of the new museum in 2010. It was capped with concrete and lies directly under the museum entrance.
