2017 Map of White Horse

About this map

The Moreau River and Little Moreau River converge in this Dewey County landscape, defining the topography near the settlement of Whitehorse. The terrain is characterized by the complex drainage systems of Whitehorse Cr and Dog Butte Cr, which carve into the plains of the Cheyenne River Reservation. Transportation in this part of South Dakota is largely defined by rural routes such as BIA Hwy 4 and the descriptively named On The Tree Rd. A prominent water feature, Whitehorse Lake, sits to the west of the main townsite. This survey provides a clear view of the cadastral grid, marked by township boundaries like t16n r26e and t15n r26e, which organize the sparsely populated cattle country and river bottomlands during the early twenty-first century.
