The Grand River meanders across this northern South Dakota landscape, defining the wide Grand Valley as it flows through the Grand River National Grassland. This 1990s revision captures a region characterized by sparse ranching operations and vast open terrain, with the T Lyman Ranch serving as a primary named landmark along the river's path. The landscape is segmented by significant survey lines, including the Fifth Standard Parallel North and the border between Perkins and Corson Counties.
