The Grand Canyon of the Yellowstone is roughly 20 miles long, measured from the Upper Falls to the Tower Fall area. The canyon was formed by erosion as Yellowstone River flowed over progressively softer, less resistant rock.
The Lower Falls is 308 ft. high and can be seen from Lookout Point, Red Rock Point, Artist Point, Brink of the Lower Falls Trail, and from various points on the South Rim Trail. The Lower Falls is often described as being more than twice the size of Niagara, although this only refers to its height and not the volume of water flowing over it. The volume of water flowing over the falls can vary from 63,500 gal/sec at peak runoff to 5,000 gal/sec in the fall. A third falls is located the canyon between the Upper and Lower falls. Crystal Falls is the outfall of Cascade Creek into the canyon. It can be seen from the South Rim Trail just east of the Uncle Tom's area. The canyon was a barrier to early travel, but became a destination for visitors when roads made the park more accessible.
