2022 Map of Edgerton South

About this map

The Coteau des Prairies upland plateau defines this section of southwestern Minnesota, where the high prairie begins its gradual descent toward the Rock River valley. This 2022 survey captures a landscape dominated by agriculture and rural infrastructure, punctuated by the small settlements of Edgerton, Hardwick, and Trosky. The drainage pattern is a defining characteristic of the terrain, with numerous watercourses like Mound Cr and Poplar Cr carving shallow valleys through the glacial till. The strictly gridded road network, featuring routes such as Co HWY 1 and Co HWY 7, highlights the persistence of the Public Land Survey System in organizing the modern township and range layout. Genealogy researchers will find these section lines and local thoroughfares like TWP RD 82 essential for pinpointing historical family farmstead locations across the Pipestone and Rock County line.
