Archaeologists found something much more fascinating than they got credit for when searching under the waters of Lake Michigan for shipwrecks: they uncovered a rock with a prehistoric carving of a mastodon, as well as a collection of stones arranged in a Stonehenge-like manner.

In modern archaeology, the use of remote sensing techniques is common: scientists regularly survey lakes and soil for hidden objects.

Archaeologists uncovered sunken boats and cars and even a Civil War-era pier at a depth of around 40 feet into Lake Michigan’s Grand Traverse Bay, using sonar techniques to search for shipwrecks, but among all these, they found this prehistoric surprise, which a trained eye can guess by looking at the sonar scans photos in this article.

“When you see it in the water, you’re tempted to say this is absolutely real,” said Mark Holley, a professor of underwater archaeology at Northwestern Michigan University College who made the discovery, during a news conference with photos of the boulder on display in 2007. “But that’s what we need the experts to come in and verify.

I remember Feb of 1966 when the news media proclaimed ancient submerged cities were found off the coast of Peru and Chile.

No new info since.

I thought the conventional wisdom claims Lake Michigan was formed by glaciers digging a path thru the area...The glaciers melted and the lakes were formed...I wonder how it is that someone was able to get in there and create these structures during that process...
