A Story of Rock and Water, Lower Yellowstone Falls

(Click image to enlarge)

Here the Yellowstone River descends 308 feet (94 meters) over a Rhyolite lava flow that was created 590,000 years ago. The rock is hard but the cold clear water is patient. It slowly wears its way through the huge obstacle as it drains last winter's snow melt and more recent rains from the largest lake above 7,000 feet (2,133 meters) in North America.
