UPPER AND LOWER FALLS

The upper and lower falls of Yellowstone are due to the erosion of the Yellowstone River flowing on progressively more tender rocks, less resistant. Upper Falls, 33 meters tall, are upstream of the Lower Falls. They can be admired from the Upper Falls Trail and Uncle Tom Trail. The Lower Falls, 94-meter high, can be seen from Lookout Point, Red Rock Point, Artist Point, the Lower Falls Trail, and various points on the southern shore trail. The flow may vary from 19 ¾ m ³/second in fall to 231 ¾ m ³/second, as much as the rainy season. A third fall is in the canyon between the Upper and Lower Falls. It can be seen from the south shore trail just east of Uncle Tom's Area.
