Cue up Duran Duran “union of the snake”?
Wasn’t the mound also put into the eroded crater of a meteorite strike?
What drew my attention was the Ohio snake's coils (3 down, 4 up). Could they have astronomical significance similar to that of the mayan, inca and aztec snake gods? Knowledge that was lost or forgotten over hundreds of years of disease, drought, earthquakes or war. Maybe the annual flooding along the Mississippi was just to much for them and they left for warmer pastures further west - the Yucatan peninsula:
Ohio snake, equinox points:
Aztec snake: Quetzalcoatl, god of knowledge, astrology and of priests, son of the creator god, a blond, blue-eyed stranger. Also known as, or very closely associated with the Mayan Kukuclan.
“Hundreds of North and South American Indian and South Pacific legends tell of a white-skinned, bearded lord who traveled among the many tribes to bring peace about 2,000 years ago. This spiritual hero was best known as Quetzelcoatl.”

Mayan snake: Kukuklan, teacher of writing and knowledge, the Vision God, underwater serpent, feathered serpent, bird messenger between the gods and the priests/royalty; the alterego of Sun God, Kininch, who controls droughts. He “ emerged from the ocean, and disappeared in it afterward.” Chichin Itzu is a calender and twice each year at the equinoxs, KuKuklan appears to slither down the side. The Snake King dynasty is associated with Mayans.
Inca snake: Pacha Kamaq, the creator son of the Sun God, a serpent from the sea who, tossed back into the sea (or a lake) became the god of fish when he wasn't making earthquakes. Pachacamac, the city dedicated to him, was a site of the Oracle - a center of knowledge and astrology. Either he was treated as invisible or his priests had to erect a cloth between them and his totum in the shape of a man so they couldn't look at it. Again, it's three down, four up on the coils, same as Ohio

My personal conjecture is that it’s a retelling of the serpent and the woman in the garden.
I’m curious as to how the know when it was built.
