1959 Map of Munker Island

About this map

Saganaga Lake and its intricate network of islands and narrows dominate this late-1950s survey of the Minnesota-Ontario borderlands. The international boundary passes through the center of the lake, separating Quetico Provincial Park to the north from the Superior National Forest and Minnesota State Forest to the south. The map documents the terminus of the historic Gunflint Trail, where the Trails End settlement and its nearby Campground provided a gateway to the Boundary Waters wilderness. This area, deeply connected to the fur trade era, is characterized by a labyrinth of water bodies including Sea Gull Lake, Alpine Lake, and the Sea Gull River. Landforms like American Point and Munker Island serve as key navigational landmarks for those traversing these connected waterways at the height of the mid-century wilderness conservation era.
