About this map

Buffalo Gap National Grassland dominates this corner of Fall River County, where the high plains of South Dakota meet the Nebraska border. The landscape is defined by an intricate network of intermittent drainages, including S Black Banks Cr and N Black Banks Cr, which carve through the open terrain. These seasonal waterways, along with the notable Dry Lake basin, illustrate the arid nature of this prairie ecosystem as it was documented in recent years.

A narrow strip of the Oglala National Grassland appears at the southern edge, marking the transition between states. Human presence is sparse, represented primarily by Co HWY 5 and a grid of rural roads that follow the Public Land Survey System sections. The drainage patterns of Medicine Cr and Horsehead Cr reveal a topography shaped by erosion, typical of the unglaciated regions of the western Great Plains.
