Spaw , finding the secret water falls is great fun. South of Fredonia NY (by the mink farm) is a clamshell waterfall into a naturally smooth stone 40 ft slip and slide. Then further down the water boils down into a DEEP crevass and bubbles out of the same hole and continues down stream eventually I assume into Lake Erie . I always thought one could put their laundry into that bubbling water hole and they would come up clean.
