An ancient petroglyph of a giant winges creature ( once showed two ) is on the rockface off River road outside of town. Early explorer Professor John Russell wrote "After a long and perilous climb, we reached the cave, which was about fifty feet above the surface of the river....The roof of the cavern was vaulted, and the top was hardly less than twenty feet high. The shape of the cavern was irregular; but, so far as I could judge, the bottom would average twenty by thirty feet.

"The floor of the cavern throughout its whole extent was one mass of human bones. Skulls and other bones were mingled in the utmost confusion. To what depth they extended I was unable to decide; but we dug to a depth of 3 or 4 feet in every part of the cavern, and still we found only bones. The remains of thousands must have been deposited here. How, and by whom, and for what purpose, it is impossible to conjecture.".
