What do people mean when they say “Niagara Falls will erode all the way to Lake Erie”?

188 views

I know that eventually the falls will go all the way back to Lake Erie, but all the articles I’ve read say that it will cease to exist, surely that’s not possible? The elevation differential won’t just disappear, right? There will still be a falls so water can get down from Lake Erie into Ontario?

The falls will get shorter the closer to Lake Erie. The whole length of the Niagara River will not evenly erode away and all wash out. Eventually the whole river will be like a giant slide.

Instead of a 180 foot drop all at once you will have a 180 foot change on an angle that could stretch for miles. It would become a rapids more that a waterfall.

This could be millions of years away though.
