of water. The shoreline of the lake stretches 2,730 miles (4393 km) (including islands).
It borders Ontario in Canada, and Minnesota, Wisconsin and Michigan in the United States of America. It is an important shipment route for iron ore and is part of the Great Lakes Waterway.
The lake is fed by over 200 rivers. The largest include the Nipigon River, the St Louis River, the Pigeon River, the Pic River, the White River, the Michipicoten River and the Kaministiquia River. Lake Superior drains into Lake Huron by the St. Mary's River. The rapids on the river necessitate the Soo Locks, a part of the Great Lakes Waterway, to move boats over the 25 foot height difference from Lake Huron.
Important towns on Lake Superior include Duluth, Minnesota, Thunder Bay, Ontario, Marquette, Michigan, Sault Ste. Marie, Ontario, and Sault Ste. Marie, Michigan.
The lake was named Lac Supérieur by French explorers because it was the highest in elevation of all the Great Lakes.
The largest island in Lake Superior is Isle Royale National Park.
The Anishinabe were primarily located around the Great Lakes region.
