About this map

The Grand River winds through the northern portion of this Corson County landscape, carving a wide valley through the expansive Ridgeland of northern South Dakota. This mid-century survey documents the area's vital transportation corridor, dominated by the Chicago Milwaukee St Paul and Pacific railroad as it parallels the river's course. Several seasonal waterways, including Snake Creek and Deep Bank Creek, drain the higher elevations of the plateau into the primary river basin. The map captures the topography of the Missouri River Basin during a period of transition, following the 1950 aerial photography and subsequent field checks that recorded the land prior to significant water management changes. The southern reaches are defined by the winding course of Claymore Creek, illustrating the complex drainage patterns that shaped this prairie environment.
