Yellowstone National Park

Yellowstone Falls consist of two major waterfalls on the Yellowstone river, within Yellowstone National Park, Wyoming United States. As the Yellowstone river flows north from Yellowstone Lake, it leaves the Hayden Valley it plunges first over Upper Yellowstone Falls and then a quarter mile (400 m) downstream over Lower Yellowstone Falls, at which point it then enters the Grand Canyon of Yellowstone which is up to 1,000 feet (304 m) deep.
