Elevation: 7,411 ft.
The Lower Falls is the tallest waterfall in the park at 308 feet. The arrow at the top of the photo points at a group of visitors on the platform at the Brink of the Lower Falls.
Over the years the estimates of the height of this falls has varied dramatically. In 1851 Jim Bridger estimated its height at 250 feet. One outrageous newspaper Story from 1867 placed its height at "thousands of feet". A map from 1869 gives the falls its current name of Lower Falls for the first time and estimates the height at 350 feet.
It mattered little how tall the observers thought the falls was. They consistently write journal entries that comment on its awe-inspiring nature. A member of the 1870 Washburn party N. P. Langford gave this brief but poetic description: "A grander scene than the lower cataract of the Yellowstone was never witnessed by mortal eyes."
