2021 Map of Fort George Butte NW

About this map

The Fort Pierre National Grassland dominates the southern half of this South Dakota landscape, illustrating the vast open grazing lands preserved between the Missouri River and the state's western plains. This 2021 survey reveals a territory primarily defined by its drainage systems and the section-line grid of the Public Land Survey System. High-country drainage is captured by Antelope Cr and Timber Cr in the north, while the southern reaches are fed by Cedar Cr and the S Br Cedar Cr. The human footprint is sparse, consisting mainly of gravel section roads like Warcreek Rd and 302nd Ave. The presence of the Williams 83 Reservoir highlights the critical role of water management in this arid ranching environment, where livestock and wildlife rely on scattered tanks and small impoundments across the grassland.
