2021 Map of Slim Butte

About this map

The White River winds through this Oglala Lakota landscape, defining the hydrology of a region where several seasonal watercourses like Alkali Cr and Janis Cr converge. The terrain is dominated by the prominent landform of Slim Butte, which shares its name with the nearby settlement. This modern 2021 topographic survey illustrates the enduring rural infrastructure of the Pine Ridge area, centered around the intersection of Bia Hwy 41 and Bia Hwy 32. Local history and genealogy interest is anchored by the Slim Buttes Cem, located south of the main settlement area. The map documents the persistent boundaries of the Public Land Survey System, including t36n r47w and t35n r47w, showing how traditional township grids overlay the natural drainages of Limekiln Cr.
