2021 Map of White Horse

About this map

Whitehorse sits at the eastern edge of this Dewey County landscape, where the Moreau River and Little Moreau River converge. The topography is defined by the drainage basins of Whitehorse Cr and Dog Butte Cr, which carve through the high plains terrain. This 2021 survey illustrates the rural infrastructure of the Cheyenne River Reservation, anchored by localized water features such as Whitehorse Lake. Transport in the area relies on a network of tribal and county routes, including Bia Hwy 4 and the descriptively named On The Tree Rd. The map also preserves the administrative grid of the Public Land Survey System, marking the boundaries of t16n r26e and surrounding townships, providing a clear record of land division and natural watercourses in this portion of South Dakota.
