New Radiocarbon Dates Suggest Serpent Mound is More Than 2,000 Years Old

July 26, 2014.
Dr. William F. Romain, of The Ancient Earthworks Project Blog, has written an interesting and informative post about new radiocarbon dates for the Serpent Mound suggesting that it is more than 2,000 years old.

"In any event, none of the median ages reported from any of our contexts within Serpent Mound are younger than 303 BC. In particular, no Fort Ancient charcoal was found in the sampled mound fill, or at the base of Serpent Mound. If the effigy was built by anyone later than Adena-era people, then one might expect to find some evidence of that in the way of organic materials or charcoal at the base. Such was not the case, however. If someone other than Early Woodland (i.e., Adena) people built the Serpent Mound, they were very fastidious in their work and left no trace at the foundation level.
