About this map

Buffalo Gap National Grassland dominates the landscape of this southwestern South Dakota quadrangle, where the Cheyenne River cuts across the northwest corner near Harrison Flat. The terrain is defined by a network of drainage systems, including Lame Johnny Cr and W Fork Willow Cr, which have carved numerous canyons into the high plains. A notable survey point is marked at Tahc'a Okute Aglehan in the northeast. The map records the interface between Custer and Fall River counties, highlighting the sparse road network consisting of local routes like Williams Pl and Riverside Rd. This 2021 survey provides a clear view of the complex topography within the national grassland, from the deep incisions of Jim Wilson Canyon to the broader expanse of Spring Canyon.
