serpent moundThe Great Serpent Mound in Southern Ohio:  Filled with mystery and surrounded by nature’s splendor, the largest and most famous Indian effigy mound in North America awaits. Serpent Mound is one of the oldest unsolved mysteries challenging scientists to unravel the mystique of the winding earthen snake some 1,300 feet long, 25 feet wide, 5 feet high and more than 1,000 years old.

Who built this fascinating earthwork, when and why? These questions have plagued scientists for more than a century.

Today, visitors from around the globe descend on Peebles, Ohio to take in the impressive view of the massive winding earthwork from high atop a tower or along a walkway hugging the serpent’s twisted body. The Serpent Mound Museum hosts captivating illustrations and stories of the mound, the theories behind its history. The park itself includes other ancient mounds and a breathtaking view of a geological anomaly, five miles in diameter, believed to have been caused by a meteorite or volcanic explosion, despite the lack of any volcanic or meteorite evidence. Much like the Great Serpent slithering toward the edge of this grand bluff, it remains a mystery.
