At 1,348 feet (411 meters), the Great Serpent Mound in Adams County, Ohio, is the largest surviving effigy mound on Earth. Its seven coils and open-jawed head are built atop a 5-mile-diameter cryptoexplosion structure — a geological anomaly caused either by a meteorite impact or volcanic diatreme approximately 300 million years ago. The serpent's head aligns to the summer solstice sunset, while its coils correspond to solstice and equinox sunrise and sunset positions. Radiocarbon dating places construction around 321 BCE (Adena culture), though some evidence suggests a 1070 CE (Fort Ancient) renovation. At Giza bearing 52.03°, the mound sits on a Pleiades alignment vector. The underlying shattered bedrock creates anomalous magnetic readings, and the site's builders chose this precise location where geological trauma, celestial geometry, and serpentine symbolism converge — a pattern found at dragon/serpent sites from Delphi to Angkor.
