Geography
South Dakota is situated in the north-central United States, and is considered a part of the Midwest by the U.S. Census Bureau; it is also part of the Great Plains region. The culture, economy, and geography of western South Dakota have more in common with the West than the Midwest. South Dakota has a total land area of 77,121 square miles (199,740 km2), making the state the 17th largest in the Union.
Harney Peak, with an elevation of 7,242 ft (2,207 m), is the state's highest point, while the shoreline of Big Stone Lake is the lowest, with an elevation of 966 ft (294 m). South Dakota is bordered to the north by North Dakota; to the south by Nebraska; to the east by Iowa and Minnesota; and to the west by Wyoming and Montana. The geographical center of the U.S. is 17 miles (27 km) west of Castle Rock in Butte County. The North American continental pole of inaccessibility is located between Allen and Kyle, 1,024 mi (1,648 km) from the nearest coastline.
The Missouri River is the largest and longest river in the state. Other major South Dakota rivers include the Cheyenne, James, Big Sioux, and White Rivers. Eastern South Dakota has many natural lakes, mostly created by periods of glaciation. Additionally, dams on the Missouri River create four large reservoirs: Lake Oahe, Lake Sharpe, Lake Francis Case, and Lewis and Clark Lake.
