Coteau des Prairies, a vast glacial upland, dominates the topography of this eastern South Dakota landscape. The terrain is characterized by a high density of prairie potholes and small wetlands, with Cherry Lake and a northern portion of Spirit Lake serving as the primary permanent water bodies. The 2021 survey reveals a strictly rectilinear road network that follows the Public Land Survey System section lines, including Efraimson Dr and Plum Lake Rd. The boundary between Clark County and Kingsbury County bisects the southern half of the quadrangle, marking a jurisdictional divide through an area otherwise defined by its uniform agricultural grid and scattered depressional basins.
