2015 Map of Cottonwood Creek NW

About this map

The Grand River carves a winding path through this northern South Dakota landscape, defining the local drainage patterns for several prominent tributaries. The river valley is joined by Cedar Boy Cr from the north and Meadow Cr from the south, creating a complex series of draws and ridges across the Rock Creek District. This 2015 survey illustrates a sparsely settled region of Corson County where the grid of public land roads, including 218th Ave and 119th St, provides the primary framework for movement between ranchlands. Further south, the terrain is shaped by Black Horse Butte Cr, illustrating the typical hydrology of the Great Plains where seasonal watercourses are vital landmarks for those tracing land use and family holdings in the T20N R20E township and its neighbors.
