Stone arrangements that appear similar to Stonehenge (UK) have been discovered around the world, and one of them lies 40 ft. below the surface of Lake Michigan.
A team of underwater archaeologists discovered the circular series of stones in 2007. One of the structure’s stones appeared to have a carving of a mastodon on it, which is an animal that has been extinct for over 10,000 years.
The ancient builders of the stones, which appear to match the layout at Stonehenge, remain a mystery, and the purpose remains unexplained.
