The Yellowstone River that flows through the Hayden Valley is the longest undammed river in the lower 48 states. It begins near Younts Peak in northwestern Wyoming, flows through Yellowstone National Park into Yellowstone Lake then empties into the Grand Canon of the Yellowstone and eventually flows into the Missouri River. The Hayden Valley is one of the most important places in Yellowstone for wildlife and birds. It is also one of the harshest places in Yellowstone in the winter with heavy snows and strong winds.
