Descripción del sitio
The Serpent Mound is a man-made earthwork in the shape of a long, uncoiling serpent nearly a quarter of a mile long. The head of the serpent is aligned to the summer solstice sunset and the coils also may point to the winter solstice sunrise and the equinox sunrise. Created between 1000 and 1500 AD for unknown purposes, the mound is now protected in a state park in Ohio.
