About this map

The White River carves a distinctive path across the northern reaches of this landscape on the border of Lyman and Tripp counties. This section of South Dakota is defined by the sharp transition from the river valley's complex drainage patterns to the upland plateaus, where a geometric grid of section lines and rural roads organizes the terrain. Waterways like Black Dog Cr and No Moccasin Cr extend southward from the river, creating a dendritic network of coulees and draws that contrast with the open country.
