South Dakota is bisected by the Missouri River, dividing the state into two socioeconomically distinct halves, known to residents as "West River" and "East River". Fertile soil in the eastern part of the state is used to grow a variety of crops, while ranching is the predominant agricultural activity in the west. The Black Hills, a group of low pine-covered mountains, is located in the southwest part of the state. (wikipedia)
