The Clam River meanders through this Polk County landscape, feeding into significant water bodies like the Clam Falls Flowage 65 and Knapp Flowage 7. This 2013 survey illustrates a region defined by its glacial heritage, most notably marked by the Ice Age National Scenic Trail as it winds northward past Margaret Lake and Crooked Lake. The terrain is punctuated by numerous kettle lakes, including Godfrey Lake, Somers Lake, and the smaller Briar Lake, which speak to the area's geological history.
