One blogger dubbed the discovery of a circle of stones on the floor of Lake Michigan as an underwater stonehedge.
Underwater archeologist Mark Holley found the circle of stones 40 feet below the surface of Lake Michigan.
Holley is shown here investigating a circle of stones on the Grand Traverse Bay floor near Traverse City, Mich.
Scientists are not sure whether the stones were arranged by humans or natural forces.
