Lower Falls of the Yellowstone River
Yellowstone National Park, USA
The Lower Falls of the Yellowstone River drop dramatically into the Grand Canyon of the Yellowstone. Surrounded by rugged, rocky cliffs and dense forest, the waterfall is one of the most stunning sights in Yellowstone National Park. The falls are approximately 308 feet high, making them the largest volume waterfall in the Rocky Mountains. The canyon's vivid colors are due to the varying composition of volcanic rock, which has been eroded over centuries.
