About this map

Medicine Knoll Cr carves a subtle path through the northern reaches of this landscape, defining the topography of a region divided by the border between Sully Co and Hyde Co. This modern survey reveals a highly organized agricultural grid, where a network of numbered section-line roads like 321st Ave, 322nd Ave, and 185th St provide access to the vast open sections of the South Dakota prairie. The landscape is characterized by numerous small, seasonal basins and depressions, typical of the glaciated terrain in this part of the state. Prominent transportation arteries such as Co Rd 649 and Co Rd 154 anchor the rural connectivity of the townships, illustrating the persistent importance of the Public Land Survey System grid in defining modern land use and boundary lines.
