the yellowstone.

The Yellowstone River, a tributary of the Missouri River, has no dams and is the longest free flowing river in the lower 48 states.  Via its tributaries, the Yellowstone river drains a wide area, stretching from the Rocky Mountains in the vicinity of Yellowstone National Park, across the mountains and high plains of southern Montana and northern Wyoming.
