South Dakota is part of Dakotas
Every Dakotas region shares one system — the same maps, the same live radar, the same climate record. South Dakota is two states in one drive. East of the Missouri is prairie and row crop, with the severe season that comes with it; west of it the ground climbs through the Badlands to the Black Hills, where Black Elk Peak is the highest point in America east of the Rockies and the snow totals have no relation to the plains twenty miles away.
