Lower Falls of the Yellowstone. The Yellowstone Falls are two in number. At the head of the Upper Fall the river has a width of about 80 feet, and the waters plunge over a shelf between walls that are from 200 to 300 feet in height. Half a mile below this Fall is the Lower or Great Fall, which is grander and more impressive than the other. Here the waters pour into the fearful abyss of the canyon, the sheer descent being 308 feet, and the wooded slopes of the gorge tower far above the flood. |
