History

The county was set off and organized in 1861. It is believed “Keweenaw” is a corruption of an Ojibwe word that means “portage” or “place where portage is made”; compare the names of the nearby Portage Lake and Portage River which together make up the Keweenaw Waterway.

Geography

Two land masses comprise most of the land portion of the county: Isle Royale and the northeastern half of the Keweenaw Peninsula. The county also includes the waters of Lake Superior between the two, extending to the state’s water borders with Ontario and Minnesota. It is thus the largest county in Michigan by total area, at 5,966 square miles (15,450 km), of which just 540 square miles (1,400 km) is land and 5,426 square miles (14,050 km) (91%) is water. Of all counties (or equivalents) in the United States, Keweenaw County has the highest proportion of water area to total area.

The largest lake entirely within the county is Gratiot Lake at 1,438 acres (5.82 km), located at the base of the county’s two highest peaks: Mt. Horace Greeley at 1,550 feet (470 m) and Mt. Gratiot at 1,490 feet (450 m). Other lakes include Lac La Belle near Bete Grise Bay, Lake Medora, Lake Fanny Hooe near Copper Harbor, Lake Bailey at the base of Mt. Baldy, and Schlatter Lake at the tip of the peninsula.

By land, one can only access mainland Keweenaw County via Houghton County.
