More Great Lakes LORE unlocked. A “Stonehenge-like” structure archaeological site was found inside Lake Michigan To be very clear, the reason why this structure was termed “Stonehenge-like” is because of the circular rock formation you see in the video. It has no bearing or connection whatsoever to the actual Stonehenge in the UK. These are not standing stones, but just normal stones arranged in a pattern. Theories as to what it could be are in the video. #archaeology #lakemichigan #lakes #geolo
