1983 Map of Square Top Butte

About this map

The Grand River National Grassland dominates this South Dakota landscape, where the open prairie is defined by prominent topographical landmarks and an intricate network of waterways. The Grand River courses through the northern reaches, fed by local drainages including Snake Creek, Defanball Creek, and Timber Draw. In the south, the terrain is marked by Thunder Butte Creek and notable high points such as Square Top Butte and Scotch Cap Butte. This 1978 field check captures the area's transition into the late twentieth century, with numerous wells scattered across the landscape indicating agricultural and resource management within the grasslands. The map also delineates civil boundaries including the townships of Cash, Marshfield, and Bison, reflecting the organized rural structure of Perkins County.
