I’ve read that Niagara Falls erodes backwards towards Lake Erie at a rate of 3 feet per year. This means that in a few hundred, maybe thousand (maybe even longer), the falls would have eroded all the way to Lake Erie. What will happen when it does? Will the lake’s floor begin to erode as well or will the water even out? I can’t wrap my head around it.

It’s calculated it would take 50,000 years to reach that point at present erosion rate. Of course that rate could change. But in 50,000 years there’s bound to be some other factors that would change the entire size/shape of the all the Great Lakes. That’s a long time.
