About this map

Buffalo Gap National Grassland dominates this landscape in southern South Dakota, where the intricate drainages of the Fall River Co plains shape the local geography. The map reveals a complex network of seasonal waterways, including the various branches of Blacktail Creek, such as the N Fork Blacktail Creek and S Br Blacktail Creek. These creek beds and draws, like West Kneebone Draw and Middle Kneebone Draw, dictate the flow of the land between high points like Rock Butte Creek.

Few structures or settlements appear in this rural expanse, with movement defined by sparse routes such as Black Tail Rd and Co Hwy 3. The grid-like division of townships, including t10s r9e and t9s r8e, provides a framework for understanding the vast grazing lands and open spaces. For those studying the hydrology or land management of the Great Plains, this survey offers a precise record of the terrain and established public lands at the beginning of the 2020s.
