The high plains of the South Dakota-Nebraska border meet at Ardmore, a settlement located near the southern edge of the Buffalo Gap National Grassland. This 2017 survey details the transition into the Oglala National Grassland just across the state line in Sioux County, Nebraska. The landscape is defined by its intermittent drainage systems, including Hat Cr, Cow Cr, and Duck Cr, which converge across the open terrain.
