The Great Serpent Mound, a three foot tall, 1,348 foot long mound of dirt piled into the shape of a snake, is about to get its 15 minutes of fame. The History Channel’s Scott Wolter will be examining the mound, located in southern Ohio’s Adams County, for their “America Unearthed” program starting January 25th. No one knows for sure who built the mound, though evidence does point to the Fort Ancient culture, but researchers think the structure was created around 1070.
