This was no Niagara. The darn thing was so high up the mountain, and you were so far below, that it was far from impressive. Good for photos? Yep, with a first rate telephoto lens.
There is a natural process of decay in those cliffs such that if you just wait a few centuries, another profile may open up all by itself. If they really feel that have to bring it back, they should find some other spot that almost looks like a profile, and chisel it a bit with dynomite.
