2021 Map of Mosher

About this map

Mosher sits at the heart of this section of Mellette County, where the plains are defined by the intricate drainage systems of Oak Cr and its tributaries. This 2021 survey illustrates a sparse ranching landscape where development is concentrated along section-line roads like 274th Street. The drainage of White Horse Cr and De Bell Cr carves into the terrain, creating a network of draws that dictate the placement of local homesteads and transport corridors. By documenting the exact positions of named creeks like McChesneys Cr, the map provides essential geographical context for understanding the historic land use and settlement patterns in this part of South Dakota.
