The 100 m false-colour image of 11 December 2016 shows us South Dakota, a state located in the Midwestern region of the United States, fully covered in snow. The state is bisected by the Missouri River, dividing South Dakota into two geographically and socially distinct halves. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 3,767 km before entering the Mississippi River. The river takes drainage from a sparsely populated, semi-arid watershed of more than 1,300,000 km², which includes parts of ten U.S. states and two Canadian provinces.
