Geology
What's behind the potholes?
The perfectly cylindrical potholes range from inches to several feet in diameter and depth and are some of the finest examples of pothole stone formations in this section of the country. Early settlers explained their great mystery with tales of how the Devil accidentally got his tail wet in the falls and was so angry, he burned holes in the stones with his hooves as he bounded away. Geologists theorize they formed when stones traveling downstream in the current got trapped in an eddy and spun around and around, the friction wearing a depression in the rock. When one rock wore itself down, another would catch in the same hole and enlarge it even more.
