1985 Map of Oak Island

About this map

The Northwest Angle State Forest dominates this unique 1980s landscape, where the northernmost point of the contiguous United States meets the international border. This survey details the intricate geography of the Lake of the Woods, showing the complex boundary between Minnesota and Ontario as it threads through Sturgeon Channel and past Garden Island. The map highlights the tribal lands of the Red Lake Indian Res and a cluster of remote islands including Penasse Island, Little Oak Island, and Crowduck Island. Navigational points like Northwest Angle Inlet and Harrison Creek illustrate the water-dependent lifestyle of this isolated enclave. The planimetric detail records the exact position of landmarks such as Sugar Point and Driftwood Point during a period of modern mapping and boundary refinement.
