1960 Map of Long Island Lake

About this map

Gunflint Lake and the international boundary between Ontario and Minnesota anchor this 1960s study of the Superior National Forest. The landscape is defined by a dense network of interconnected waterways, where the Gunflint River and Cross River flow through a complex system of glacial basins including Seagull, Magnetic, and Long Island Lake. Early 20th-century infrastructure is visible at the Forest Service Guard Station and the Gunflint Lookout Tower, which monitored the surrounding timberlands. Human activity in this remote wilderness is concentrated along the Gunflint Trail and near isolated resource extraction sites like Mine Lake and various Gravel Pits. The map documents a transition point where the Superior National Forest meets the Minnesota State Forest, preserving a record of the region's hydrography and forestry management before modern developments.
