The Grand Canyon of the Yellowstone is the primary geologic feature in the Canyon District. It is roughly 20 miles long, measured from the Upper Falls to the Tower Fall area. Depth is 800 to 1,200 ft.; width is 1,500 to 4,000 ft. The canyon as we know it today is a very recent geologic feature. The present canyon is no more than 10,000 to 14,000 years old, although there has probably been a canyon in this location for a much longer period. The exact sequence of events in the formation of the canyon is not well understood, as there has been little field work done in the area. The few studies that are available are thought to be inaccurate. We do know that the canyon was formed by erosion rather than by glaciation. A more complete explanation can be found in the Geological Overview section.

The geologic story of the canyon, its historical significance as a barrier to travel, its significance as destination/attraction, and its appearance in Native American lore and in the accounts of early explorers are all important interpretive points. The "ooh-ahh" factor is also important: its beauty and grandeur, its significance as a feature to be preserved, and the development of the national park idea.

The Upper and Lower Falls of the Yellowstone

The falls are erosional features formed by the Yellowstone River as it flows over progressively softer, less resistant rock. The Upper Falls is upstream of the Lower Falls and is 109 ft. high. It can be seen from the Brink of the Upper Falls Trail and from Uncle Tom's Trail.

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.
