The Little Missouri River is the central, unifying feature of this wild and broken land where, as a young man, Theodore Roosevelt ranched and hunted in the 1880s. The park is part of both the Northern Great Plains and the West, blending a rich natural beauty with diverse human history. The rugged topography, with its flora and fauna, also provides an opportunity to discover the badlands environment as Roosevelt once did. It is a place to experience a land and way of life that helped shape Theodore Roosevelt's attitudes and philosophy regarding conservation. Cottonwood trees surrounding the campsite turn golden in the fall.
