2017 Map of Artichoke Butte NW

About this map

The Missouri River corridor dominates this landscape, where the waters of Lake Oahe fill the valley along the borders of Dewey, Potter, and Sully Counties. This modern survey reflects the vast reservoir system that altered the central South Dakota riverbanks, submerged historical shorelines, and created the intricate inlets visible at Pascal Cr and Parker Cr. To the west of the water, the terrain is marked by the drainages of Bull Cr and Alberts Cr, which cut through the high plains of the Cheyenne River Reservation. Transportation is sparse in this open country, primarily represented by Bia Rd 8 winding through the northwest corner. The map provides a clear view of the Public Land Survey System grid, including T12N R30E and T117N R79W, documenting the administrative boundaries and township lines that define land ownership in this riverine region.
