English: The flatiron-shaped Coteau des Prairies plateau, dusted by snow. The plateau, which is mostly in northeastern South Dakota, points its northern tip into the southeastern corner of North Dakota. This series was shot on a flight from London To Los Angeles on a midwinter day. The plateau was deposited by a series of glaciers in the Pleistocene, and is dotted by almost countless lakes. Much of it is also in the Lake Traverse Indian Reservation. In the distance are Lake Traverse and Big Stone Lake, on the border of Minnesota. Lake Traverse flows north toward Hudson Bay and Big Stone Lake flows south toward the Gulf of Mexico.
