2021 Map of Mouth of Little Dog Creek

About this map

The White River carves a winding path through this South Dakota landscape, creating a dramatic corridor of deeply dissected breaks and ridges that contrast with the surrounding high plains. The confluence where Little Dog Cr enters the river valley defines the central topography, while the Pahapesto Buttes rise as prominent landmarks along the eastern edge. This 2021 survey reveals a territory structured by the intersection of Lyman, Mellette, and Tripp counties, where the land is primarily organized by a sparse network of section-line roads like 297th Ave and 300th Ave. Significant drainage systems including Sedlano Cr and Oak Cr feed into the river basin, illustrating the complex erosion patterns typical of this Missouri Plateau region. The map preserves the modern rural character of the area, showing the enduring ranching and agricultural framework of south-central South Dakota.
