2021 Map of Groton SW

About this map

West Hanson Cem sits near the junction of 140th St and 402nd Ave, marking a quiet historical anchor in this rural portion of Brown County. The landscape is defined by the subtle drainage patterns of Mud Cr in the northwest and Dry Run in the southeast, which carve gentle paths through the agricultural sections. The map reveals a precise grid of township roads, including the prominent north-south corridor of Co Rd 18. This 2021 survey by the U.S. Geological Survey captures the enduring Public Land Survey System structure, with township lines for T122N and T121N clearly delineated. The arrangement of section lines and access roads reflects a long-standing commitment to prairie agriculture, where every mile is indexed by routes like 143rd St and 401st Ave.
