About this map

The White River winds through the northern half of this landscape, forming a natural boundary that defines the drainage patterns of south-central South Dakota. Along its banks lies Gunny Sack Bottom, a notable alluvial feature in a region dominated by the dissected uplands of the Great Plains. These plains are carved by several seasonal drainages, including Mill Iron Cr in the northwest and the winding course of Dog Ear Cr which cuts through the southern sections.

Evidence of the region's historic cattle and ranching history is visible in the network of rural roads that follow section lines and older trails, such as Wagon Rd and Sundance Rd. The map tracks the border between Lyman and Tripp Counties, which zigzags across the river's channel. Other local routes like Calhoon Rd and various numbered section roads provide the primary access to this largely agricultural and open grazing country.
