Not trying to be negative but if this is a scan from a depth of 40 feet then these stones are tiny
Unless somone can shed light on this !!
Since 2008, researchers from the University of Michigan have been using side-scan sonar and a remotely operated vehicle (ROV) to search two separate areas beneath Lake Huron for a total of 72 square miles in an area known as the Alpena-Amberley ridge. Some 9,000 years ago, water levels were lower and the ridge would have been a dry-land corridor that connected the northeastern Lower Peninsula with Ontario.
Those living between 10,000-7,500 B.C. could walk across the rocky, barren land bridge in the bitter-cold weather. Researchers believe the early hunters likely did exactly that, and so did their prey: caribou.
