Searching for shipwrecks in Lake Michigan, an archaeologist found a ring of stones on the lake bed. One seemed to bear a carving of a mastodon.

What was reported

In 2007, Mark Holley, an underwater archaeologist, was using sonar to search for shipwrecks in Grand Traverse Bay on Lake Michigan when he found a line of stones arranged in a curve, about 12 metres under the water.

When divers went down, they found that one of the stones appeared to have a carving on it that looked like a mastodon, an animal that died out in the region over 10,000 years ago. If it was human-made, it could date from a time when the lake level was much lower.

Explanations offered

Other scientists are cautious, and some think the 'carving' could be natural marks on the rock. The site's location has been kept secret, in agreement with local Native American tribes, to protect it. It hasn't been fully studied.
