The Great Serpent Mound is a prehistoric effigy earthwork of a serpent uncoiling located on a wedge-shaped, slightly convex ridge in the rolling hills of southern Ohio where it overlooks a waterway called Brush Creek. From the tip of its nose to the end of its tail, the effigy is 1,370 feet long and varies in height from less than a foot to more than three feet. Conforming to the curve of the land on which it rests, the head of the serpent approaches a cliff above a stream as its body winds back and forth for more than eight hundred feet and seven coils, and ends in a triple-coiled tail. The serpent head has an open mouth and appears to be swallowing an egg, or perhaps the sun.
