Geography

Fall River County lies at South Dakota's SW corner. Its south borderline abuts the north borderline of the state of Nebraska, and its west borderline abuts the east borderline of the state of Wyoming. The Fall River County terrain contains a mountainous area in the north-central portion, with rolling hills in the rest of the county. Outside the mountainous area, the county's highest point is its SW corner, at 3,970 ft (1,210 m) ASL. Of the several peaks in the mountainous area, one in the NE portion of that zone rises to 4,646 ft (1,416 m) ASL. The terrain slopes to the north and east. Discharging from the Angostura Reservoir, the Cheyenne River flows northeasterly through the upper part of the county, departing the county through its north boundary line into Custer County.

Fall River County has a total area of 1,749 square miles (4,530 km2), of which 1,740 square miles (4,500 km2) is land and 9.2 square miles (24 km2) (0.5%) is water.[4]
