2015 Map of Mouth of Mission Creek

About this map

The White River winds through the northern frontier of the Rosebud country, forming a distinct natural boundary as it flows eastward between Lyman and Tripp counties. This landscape is defined by the convergence of several drainages, including the lengthy Mission Cr and Cottonwood Cr, which carve deep paths through the prairie breaks toward the river valley. The topography reveals a sparsely settled ranching territory where local movement relies on a grid of section line roads like 257th St and named tracks such as Bison Rd and Paradise Rd. The map illustrates the persistent geography of South Dakota's river systems, showing the intricate feeder creeks like Big Ear Cr and Mill Iron Cr that drain the surrounding highlands.
