Serpent Mound Aerial Exploration: Ohio's Mysterious Earthworks

Serpent Mound is a 1,370 ft long effigy mound in Adam's County, Ohio and sits on the edge of a meteor impact crater that is 4.5 km across and has powerful magnetic and gravitational anomalies. These anomalies cause all sorts of weather fluctuations and earth energy effects in the form of earth lights. For a long time conventional archaeology dated Serpent Mound to the Late Woodland period of 1,070 AD, but recent radiocarbon analysis has put it at around 321 BC4 (one year after the death of Aristotle). This puts it in the realm of the Adena who were present in the area at this time.
