Theodore Roosevelt National Park

Theodore Roosevelt National Park is an American national park comprising three geographically separated areas of badlands in western North Dakota. The park was named for U.S. President Theodore Roosevelt. The park covers 70,446 acres of land in three sections: the North Unit, the South Unit, and the Elkhorn Ranch Unit.

The park's larger South Unit lies alongside Interstate 94 near Medora, North Dakota. The smaller North Unit is situated about 80 mi north of the South Unit, on U.S. Route 85, just south of Watford City, North Dakota. Roosevelt's Elkhorn Ranch is located between the North and South units, approximately 20 mi west of US 85 and Fairfield, North Dakota. The Little Missouri River flows through all three units of the park. The Maah Daah Hey Trail connects all three units.
