About this map

Thor sits at a remote road junction in central Minnesota, serving as a quiet focal point in a landscape dominated by extensive wetlands and glacial lakes. This 1969 field check reveals a region defined by its conservation areas, notably the Rice Lake National Wildlife Refuge in the northeast and the Swamp Lake State Wildlife Management Area further south. These protected lands emphasize the importance of the local ecosystem, where Dam Brook meanders through the lowlands connecting various water bodies.

Local landmarks such as Zion Ch provide evidence of the small-scale community life established in townships like Glen and Lee. The map documents a transition toward outdoor recreation, evidenced by the Campground and multiple boat ramps located at Clear Lake and Swamp Lake. This survey provides a clear look at the hydraulic connections between Long Lake, Sugar Lake, and the surrounding marshes before further modern development.
