The location of Niagara Falls has changed over time. As The Falls migrates upstream, the shape of the crest has alternated over time from a horseshoe shape, as seen in the crest lines in 1678, 1764, 1842 and the current crest line; and a V-notch shape as seen in the crest line of The Falls in 1819 (Picture 2).
How will Niagara Falls change in the future?
The falls could be replaced by a series of rapids. 50,000 years from now, at the present rate of erosion, the remaining 20 miles to Lake Erie will have been undermined. There won’t be a falls anymore, but there will still be a river at work.
