That's nice and all, but it's been over 3 years since that article. Surely they would have figured more information out by now.
Specialists shown pictures of the boulder have asked for more evidence before confirming the markings are an ancient petroglyph, said Holley, an underwater archaeologist who teaches at Northwestern Michigan College in Traverse City.
"The difficulty I saw was that the features of what's interpreted as an engraving were so subtle, and they're not the only thing on the boulder," Fisher said in a phone interview.
"It's conceivable" that the image on the rock is a petroglyph, he said. "I'm intrigued enough to take another look."
Some -- although not the boulder -- were arranged in a circle. That could indicate human manipulation although it's unclear, said Rob Houston, a geology instructor at the college who has inspected the site.
