2017 Map of Fort George Butte SW

About this map

Fort Pierre National Grassland dominates this Lyman County landscape, preserving a vast expanse of mixed-grass prairie. This 2017 survey details the complex drainage patterns of the northern Great Plains, where seasonal waterways like S Br Cedar Cr, Nail Cr, and Stony Butte Cr carve winding paths through the terrain. The map highlights a remote section of the public land system, largely defined by its lack of permanent settlements and characterized by its section-line road network. Vital transit corridors such as Co Hwy 25 and Co Rd 16 provide access across these grasslands, marking the modern human footprint on a landscape that remains largely open and undeveloped. For those studying the geography of South Dakota's public lands, this sheet provides a high-resolution look at the hydrography and elevation contours of this specific township and range configuration.
