About this map

Buffalo Gap National Grassland dominates this corner of Fall River County, where the high plains landscape is carved by a complex drainage system. The Cheyenne River flows through the northeast, fed by seasonal watercourses like Moss Agate Cr, Driftwood Cr, and Dry Cr. Evidence of early 21st-century land management and water control is visible through features like the Fiddle Cr Reservoir and the Tubbs Canal, which divert water across this arid rangeland. The township and range lines of t8s r1e and t9s r2e provide a clear structural grid for the territory, while local infrastructure is represented by routes such as Co Hwy 9a and Co HWY 9. This survey is particularly useful for understanding the intersection of federal grazing lands and hydraulic engineering in southwestern South Dakota.
