Michigan’s Stoned or Michigan’s “Stonehenge”


I like to roam the internet for the weird and wonderful and this morning I came upon an article about a 9,000 year old stone structure, located only 40 feet below the surface and Stonehenge-like in composition, from 2015. Nestled snugly between an advertisement for Ink+Volt and a promo for a “free” Numerology reading was a remarkable tale regarding stone structures found at the bottom of Lake Michigan.

The stones are located near Grand Traverse Bay Underwater Preserve. Mark Holley, a professor of underwater archaeology at Northwestern Michigan University College, found the site with his colleague Brian Abbot in 2007. The ship they were piloting was equipped with sonar equipment used to find shipwrecks on the bottom, but the two found much more.

The stones appeared to be lined up, some in octagonal formations, and included one stone on which was carved a mastodon, a prehistoric creature that lived over 10,000 years ago.  Researchers were shown photos of the carving and requested additional imaging of the ancient petroglyph.  Charles Cleland, former curator of Great Lakes archaeology and ethnology at Michigan State University says that, although petroglyphs are rarely seen in the Upper Midwest, he can see the value of investigating further and does not rule out the idea that this may be an authentic piece of ancient history.


The structure at the bottom of Lake Michigan is not unique. Other stone structures have been located in other Great Lakes and ancient structures found underwater are not entirely unusual. In the Mediterranean alone, over 100 cities have been discovered as well as pyramids and other ancient structures. Geographical history of the location (coordinates have been kept secret to prevent visitors from disturbing the site) shows that the land would have been tundra 6000-9000 years ago, so the stones could have been used to mark some sort of ceremonial site. It has also been speculated that the stones could have been some sort of “drive line” and used as early hunting blinds. If you consider the fact that a meager 5% of the world’s oceans have been explored, who knows what else could be down there.
