About this map

The White River carves a winding, serpentine path across this landscape, defining the county line shared by Jones and Mellette Counties. The terrain is characterized by a series of deeply eroded drainages and tributary systems, including Cottonwood Cr and Yukon Cr to the north, while Cedar Cr and Roundup Cr flow through the southern breaks. The geographic orientation of the region is established by the local road network, specifically 259 Ave and 260 Ave, which cut across the high ground between the river valleys. This survey illustrates the intricate topography of the South Dakota plains, where the land is shaped almost entirely by the movement of water toward the river channel, creating a complex network of draws and ridges.
