About this map

Big Round Lake dominates this glaciated landscape in northern Polk County, surrounded by a dense network of smaller basins and wetlands that characterize the region's hydrography. The settlement of Johnstown is positioned on the eastern shore, marked by the presence of the Johnstown Cem. The terrain is significantly shaped by the Ice Age National Scenic Trail, which winds through the central portion of the map, following the ridges and depressions between water bodies like Straight River and McKenzie Lake.

This 2015 survey reveals a land defined by its post-glacial features, from the flowing Clam River in the northeast to the sprawling Devils Marsh. The map provides a detailed view of local infrastructure, including family-named sites such as Footes Lake and Mullins Lake. For those studying local land divisions, the map clearly delineates the boundaries of townships T35N and T36N, illustrating how rural roads like Round Lake Rd and 250th Ave navigate around the numerous lakes and marshes.
