Lower Falls of the Yellowstone River

The Lower Falls of the Yellowstone River is one of the largest volume waterfalls, if not the largest, in the Rocky Mountains of the United States. Depending on the time of year, anywhere from 5,000 to 60,000 gallons per second (18,927-227,125 l/s) of water plunges 308 feet (93 m) over volcanic rock into the Grand Canyon of the Yellowstone. Several viewpoints offer various perspectives of this stunning display of nature.
