South Dakota is the Mount Rushmore State, a land of sweeping Great Plains, dramatic Badlands formations, and the storied Black Hills. From the granite faces of four presidents to the fossil-rich Badlands, the buffalo herds of Custer State Park, and the raucous saloons of Deadwood, South Dakota rewards travelers with authentic American West experiences far from the usual tourist circuits.
South Dakota has a semi-arid continental climate with dramatic swings between seasons. Summers (June–August) are warm to hot with afternoon thunderstorms; winters (December–February) are cold and snowy with dangerous wind chills. Spring and fall are brief but beautiful, especially in the Black Hills. The Badlands can exceed 100°F (38°C) in July and drop to single digits in January.
