1968 Map of Isle SW

About this map

The Mille Lacs State Wildlife Management Area anchors the southern portion of this landscape, where the boundary between Mille Lacs and Kanabec counties cuts through a terrain defined by complex wetland systems and small watercourses. The drainage of the Knife River and Hay Brook dominates the central and northern sections, reflecting the glaciated topography of central Minnesota in the late 1960s. Surveyed for the township divisions of Isle Harbor, Lewis, and Hillman, the map reveals a sparsely populated region primarily utilized for conservation and resource extraction. Human presence is marked by the Isle Harbor Lookout Tower and scattered industrial sites, including a Quarry and multiple Gravel Pits, which suggest the local importance of aggregate mining within this heavily forested and marshy environment.
