Sylvan Lake (South Dakota)
Sylvan Lake is a lake located in Custer State Park, in the Black Hills of South Dakota, United States. It was created in 1881 when Theodore Reder built a dam across Sunday Gulch Creek. The lake area offers picnic places, rock climbing, small rental boats, swimming, and hiking trails. It is also popular as a starting point for excursions to Black Elk Peak and The Needles. A hotel was operated on the shore of the lake in the early 20th century.
The lake was featured in Disney's 2007 film . The film made the lake appear to be located directly behind Mount Rushmore when in reality it is actually five miles southwest of Mount Rushmore.
