2021 Map of Fort George Butte

About this map

Fort Pierre National Grassland dominates the southwestern portion of this prairie landscape, where the administrative boundary between Stanley and Lyman counties follows the path of Co Hwy 21. The terrain is defined by an intricate network of drainage systems, including the headwaters of La Roche Cr and Straight Cr, which carve through the high plains toward the Missouri River valley. The most prominent landmark is Ft George Butte, a high point in the northeast that served as a natural navigational marker in the vast grassland. Ranching life is suggested by the presence of Dipping Tank Cr and a grid of section-line roads such as 304th Ave and 218th St. This area preserves a largely undeveloped view of the South Dakota plains, where seasonal waterways like Plum Cr and Cedar Cr dictate the layout of local travel and land use.
