dismissed the need for a second rope -a safety stand-by-for a descent of a mere 15 feet. Why? I am a biologist, and the prospect of capturing a blind fish had blocked all else out of my mind. I had searched dozens of Ozark caves in vain, but local gossip "guar anteed" the rare fish's presence in this little grotto. Ken peered down, saw my pre dicament, and went back to the car for a longer rope. While I waited I saw that the water was getting mud dy. The falls roared louder. I realized that the water was rising-it was now knee-deep. Storm runoff had begun to pour in through some un known opening.

George Moore of the United States Geological Survey works his way down a ladder of aluminum-alloy rungs strung on aircraft cable. Winter chilled air freezes the falls. In summer the threat of flash floods makes the little-known cave perilous to visitors. 804 KODACHROMEBY HUNTLEY INGALLS © N.G.S.
