2017 Map of Mouth of Little Dog Creek

About this map

The White River meanders prominently across this South Dakota landscape, carving a deep valley that serves as the boundary between Lyman and Mellette counties. This 2017 survey captures a remote ranching region characterized by sharp topographic relief, particularly near the Pahapesto Buttes in the southeastern quadrant. The drainage network is complex, with several seasonal tributaries including Little Dog Cr, Sedlano Cr, and Oak Cr feeding into the main river channel. Transport is limited to a sparse grid of section-line roads such as 252nd St and the winding River Rd, which follows the river's northern bench. The map provides a precise look at the Public Land Survey System divisions, documenting the township and range intersections where Mellette, Lyman, and Tripp counties converge.
