Thanks to those first explorers who paddled the river and shared their stories and photographs, Yampa River Canyon became the object of preservationists, ultimately leading to a presidential proclamation by Franklin D. Roosevelt to name the 210,000-acre river corridor a national monument in 1938.
The publicity also enticed thrill-seekers to plan a ride down the river through Dinosaur National Monument solely for recreation. This was the beginning of Colorado’s whitewater rafting industry. Today, you can still float down the Class III–IV Yampa waters, as well as the Green River (also found with in the monument), with several outfitters or get your own permit through a lottery system; however, availability is limited so competition is fierce.
