The county is encompassed within the Standing Rock Indian Reservation, which extends into North Dakota. The Lakota people reside primarily in the South Dakota part of the reservation; the Yanktonai and Dakota live in that part in North Dakota. The Grand River, a tributary of the Missouri River, runs through the reservation.

Geography

Corson County lies on the north line of South Dakota. Its north boundary line abuts the south boundary line of the state of North Dakota. The Missouri River flows south-southeastward along its eastern boundary line. The county terrain consists of semi-arid rolling hills. A portion of the land is dedicated to agriculture.[3] The Grand River flows eastward through the central part of the county to discharge into the river, and Standing Cloud Creek flows eastward through the county's lower SW area. The terrain generally slopes to the east and south; its highest point is near its NW corner, at 2,582' (787m) ASL.[4]

Corson County has a total area of 2,530 square miles (6,600 km2), of which 2,470 square miles (6,400 km2) is land and 60 square miles (160 km2) (2.4%) is water.[5] It is the fifth-largest county in South Dakota by area. The entire county lies within the Standing Rock Indian Reservation, which also includes Sioux, Ziebach, and Dewey counties.

The eastern portion of South Dakota's counties (48 of 66) observe Central Time; the western counties (18 of 66) observe Mountain Time. Corson County is the easternmost of the SD counties to observe Mountain Time.[6]

Politics

Like Ziebach County, and unlike the arch-Republican white West River counties, Corson is a competitive, fluctuating swing county. It voted Democratic in the three elections from 2004 to 2012 – doing so by over twenty percentage points for Barack Obama in 2008 – but as with most Native American counties there was a substantial swing against Hillary Clinton in 2016.
