USA - Serpent Mound

"Serpent Mound, in Adams County, is the largest documented surviving example of a prehistoric effigy mound in the world. It is a sinuous earthen embankment 411 meters long, including an oval embankment at one end, which has been interpreted variously as the serpent's eye, part of its head, or a secondary object, such as an egg, grasped in the serpent's open jaws. The effigy ranges from 1.2 to 1.5 meters in height and from 6 to 7.6 meters in width. Radiocarbon dates obtained from samples from the effigy, combined with stylistic analyses of the iconography, indicate Serpent Mound was built by the Fort Ancient Culture about the year 1120 CE. This state memorial also preserves three Native American burial mounds as well as evidence of contemporary habitation sites." Source: UNESCO World Heritage Tentative List
