Keweenaw National Historical Park

Keweenaw National Historical Park is a unit of the U.S. National Park Service. Established in 1992, the park celebrates the life and history of the Keweenaw Peninsula in the Upper Peninsula of the U.S. state of Michigan. It is a federal-local cooperative park made up of two primary units, the Calumet Unit and the Quincy Unit, and almost two dozen cooperating "Heritage Sites" located on federal, state, and privately owned land in and around the Keweenaw Peninsula. The National Park Service owns approximately 1,700 acres in the Calumet and Quincy Units. Units are located in Baraga, Houghton, Keweenaw, and Ontonagon counties.

The Congressional legislation establishing the Park stated, among other things, that: The oldest and largest lava flow known on Earth is located on the Keweenaw Peninsula of Michigan. This volcanic activity produced the only place on Earth where large scale economically recoverable 97 percent pure native copper is found.
