2015 Map of Fort George Butte SW

About this map

Ft. Pierre National Grassland dominates this portion of Lyman County, preserving a vast expanse of mixed-grass prairie that reflects the enduring ranching character of central South Dakota. The drainage patterns of the high plains are clearly delineated by the winding courses of S Br Cedar Cr in the north and the headwaters of Stony Butte Cr and Nail Cr in the south. This 2015 survey illustrates a landscape of sparse human settlement, where the grid of the Public Land Survey System is articulated by rural corridors such as Co Hwy 25, Co Rd 16, and section roads like 228th St. The map provides a precise view of the topography within Townships 107n and 108n, showing the subtle but complex draws and ridges that define this protected grassland environment.
