Ore Boat leaving Duluth Harbor in a northeaster, Duluth, Minnesota, 1920s Print

Stormy view of an ore boat leaving Duluth Harbor in a northeaster circa the 1940s.

Located at the westernmost tip of Lake Superior, the Port of Duluth-Superior is North America’s farthest-inland freshwater seaport. A remarkable 9-mile natural breakwater shelters the port’s 49 miles of harbor frontage. Twenty privately owned bulk cargo docks and an award-winning general cargo terminal populate the working waterfront, along with a marine fueling depot, a shipyard with dry docks, multiple tug and barge services, plus an intermodal cargo terminal.
