1954 Map of Thompson Lake

About this map

The Cloquet Valley State Forest dominates this northern landscape, where the winding Cloquet River and its tributaries define the regional geography. Surveyed in the mid-1950s, the map reveals a wilderness area heavily shaped by water management and resource extraction. The vast Island Lake Reservoir occupies the southern section of the quadrangle, with its shoreline intricately carved by the surrounding terrain. To the north, a series of connected waterways including Alden Lake, Little Alden Lake, and Spring Lake create a complex aquatic network. Human activity is sparsely represented, primarily through a network of unimproved dirt roads and a lone Gravel Pit near the reservoir, illustrating the era's focus on timber and water resources rather than dense settlement. The topography is further marked by the townships of Gnesen and Normann.
