About this map

Chippewa National Forest and the Land O' Lakes State Forest converge in this northern Minnesota landscape, creating a densely wooded region defined by its complex glacial hydrology. Central to the map is the expansive Thunder Lake, while the northern portion is dominated by the marshy shores of Big Rice Lake and the branching flow of the Willow River. The presence of the Townhall near the forest boundary and the Steiner Landing Strip in the northwest suggests a sparse but established administrative and transport infrastructure in the early 1970s.

Local landmarks such as the Draper Lookout Tower and a nearby Radio Tower emphasize the importance of fire surveillance and communication in this heavily forested terrain. Numerous smaller bodies of water, including Coffin Lake, Bass Lake, and the uniquely named Kidney Lake, are interspersed among the ridges and depressions of Smoky Hollow, illustrating the intricate natural drainage patterns of Cass County before further modern development.
