1960 Map of Gunflint Lake

About this map

Gunflint Lake and Loon Lake dominate this 1960 survey of the international boundary between Ontario and the United States. The map documents a landscape defined by its glacial hydrology and early industrial transit, most notably the Old Railroad Grade and the winding Gunflint Trail. These features suggest a period of transition as timber and transport routes gave way to the protected recreational areas of the Superior National Forest and Minnesota State Forest. Researchers can trace the network of interior waterways like the Tucker River, which connects chains of smaller bodies including Tucker Lake and East Dawkins Lake. The map provides detailed bathymetric and topographic data for the deep-water lakes along the border, reflecting a wilderness era before the widespread modernization of the northern frontier.
