1971 Map of South Point

USGS Topo · Published 1974

About this map

Michigan Islands National Wildlife Refuge and the southern shoreline of Thunder Bay define this coastal landscape on the edge of Lake Huron. The map illustrates a transitional zone where public lands and conservation efforts converge, featuring Thunder Bay River State Forest and Alpena State Park along the mainland's edge in Sanborn. This 1970s survey captures the intricate hydrography of the Great Lakes coastline, noting offshore hazards like Scarecrow Island and Bird Island. The presence of the Detroit and Mackinac railroad line running parallel to the coast highlights the transportation infrastructure necessary to serve this portion of Alpena County. From Hardwood Point to South Point, the map provides detailed bathymetric data and shoreline contours essential for understanding the maritime history and land use of the Alpena area.
