Underwater Archaeologists Find Possible Mastodon Carving On Lake Michigan Rock

Traverse City, MI (AHN) - Underwater archaeologists in Lake Michigan's Grand Traverse Bay are speculating a boulder they found in a June ship wreck to be engraved with a prehistoric carvings.
Mark Holley, a scientist with the Grand Traverse Bay Underwater Preserve Council, believes that the granite rock, which was found hidden at a depth of about 12 metres, has markings that resemble a mastodon.
A mastodon is an elephant-like creature that once inhabited parts of North America. It also carried what appeared to be a spear in its side.
Accepting the fact that they need the experts to come in and verify if the carvings are an ancient petroglyph, Holley said he has shown pictures of the boulder to them. Michigan has only a couple of confirmed petroglyphs.
Since the petroglyphs experts are not able to dive in sea water, the scientists say they are facing trouble showing the exact carvings to the experts.
Though the exact location of the boulder is not unveiled to prevent it from theft, scientists say it lies within the 50-kilometre-long (31 miles) bay on the flat, sandy lake floor.
Holley also told the Associated Press that the boulder is a part of a row of stones of varying sizes that might have marked the shoreline 6,000 to 10,000 years ago. The boulder with the markings is about one metre high and about 1 1/2 metres long.
