1961 Map of Blind River

About this map

Drummond Island and St Joseph Island anchor this detailed 1980 revision of the international border between Michigan and Ontario. The map traces the rugged northern coast of Lake Huron and the sheltered waters of the North Channel, where numerous small settlements like Bruce Mines and Thessalon are linked by the Canadian Pacific railroad. This region, shown as it appeared in the late twentieth century, displays a distinct transition from the forested interior of Mississagi Provincial Park and the high ridges of the La Cloche Mtns to the intricate bays of Potagannissing Bay. The network of interior lakes, such as Wakomata Lake and Quirke Lake, suggests a landscape defined by the drainage of the Mississagi River and the Serpent River, supporting both timber and early mining operations throughout the Algoma District.
