Theodore Roosevelt National Park · North Dakota Scenic River
The river that made Theodore Roosevelt a conservationist — winding 560 miles through the painted Badlands of western North Dakota. The Little Missouri carved the dramatic buttes, hoodoos, and coulees of Theodore Roosevelt National Park. Remote, unpredictable, and stunningly beautiful.
