1978 Map of Coffee Flats

About this map

Coffee Flats sits at the intersection of the Wyoming and South Dakota border, a high plains landscape defined by a complex network of seasonal drainages and livestock infrastructure. Surveyed in the 1970s, the terrain is marked by the Black Hills Meridian and organized around numerous livestock watering points, or Tanks, scattered across the draws. The hydrology of the area is distinct, with East Mule Creek in the northwest and Coffee Cr and Little Cottonwood Cr in the east. Human activity is largely industrial and agricultural, evidenced by Gravel Pits and various fence lines. The map reveals the precise boundary between Niobrara County, Wyoming and Fall River County, South Dakota, showing how state and county lines cut across the natural geography of North Cottonwood Creek and Hollingsworth Draw.
