Beneath the waters of Lake Michigan lies an ancient mystery a stone circle estimated to be over 9,000 years old, older than even Stonehenge. Divers and archaeologists uncovered carefully arranged stones along with carvings of mastodons, megaloceros, and most baffling of all—a cobra, an animal that never existed in North America.
How could ancient people have known about such creatures? Were they tapping into a lost knowledge or had distant connections we've yet to uncover?
Whether it served as a sacred site, a ceremonial gathering place, or something far more mysterious, this submerged circle continues to challenge everything we thought we knew about early civilizations.
