The industrial and maritime heart of the Twin Ports is revealed in this detailed 1980 survey, where the St Louis River empties into Lake Superior. The map centers on the critical rail and water junction of Duluth and Superior, highlighting the complex transportation corridors used by the Burlington Northern and the Duluth Missabe and Iron Range railroads. Beyond the urban centers, the landscape transitions into the heavily wooded tracts of the Fond Du Lac State Forest and the Fond Du Lac Indian Reservation.
