The Lower Falls of the Yellowstone River drops 308 feet at the head of the Grand Canyon of the Yellowstone. The canyon is approximately 10,000 years old, 20 miles long, 1000 ft deep, and 2500 ft wide. Its yellow, orange and red-colored walls are due to oxidation of the various iron compounds in the soil, and to a lesser degree, sulfur content. Yellowstone National Park, Wyoming, USA
