The Brule River forms a jagged natural boundary between Wisconsin and Michigan on this 1947 survey, defining the southern edge of the Mastodon area. This landscape was largely dominated by the timber and transport economy of the mid-20th century, centered on the Chicago and Northwestern railroad line. The settlement of Naults sits along these tracks, serving as a key point of reference in a terrain characterized by wetlands and small waterways like Mud Lake and the W Branch Armstrong Creek. Interestingly, a significant portion of the map is designated as an Unsurveyed Area, reflecting the frontier nature of this northern borderland during the postwar period. Local watercourses such as McGoverns Cr drain this wooded interior, illustrating the topographical isolation of the region at the time of the 1945 mapping.
