The prairie landscape of Polk County is defined by the intersection of rail and river near the settlements of Erskine and McIntosh. This modern survey reveals a region heavily managed for agriculture and drainage, evidenced by the Poplar River Diversion Ditch cutting across the plains to control the flow of the Poplar River. The township lines of t148n r42w and t148n r41w are dotted with numerous glacial lakes, including the prominent Oak Lake and the smaller Squirrel Lake, providing a distinct contrast to the rigid grid of county roads and section lines.
