In 2001, a couple of marine scientists were mapping the Lake Michigan floor and scanning for shipwrecks when they discovered a submerged structure with what appeared to be prehistoric mastodon carvings. The structure was found with a couple of stones in an arrangement reminiscent of Stonehenge.

The boulder was found to be about 5 feet long, and 3.5 to 4 feet high. The team that discovered this underwater mystery was led by Marc Holly, an Underwater Archaeology professor, and Brian Abbott; they put the structure’s age at about 9,000 years and declared it similar to Stonehenge, hence the name.
