Stonehenge Analog Sunk in Lake Michigan?

"Stonehenge Beneath the Waters of Lake Michigan"
BLDGBLOG (Monday, January 5, 2009)

"n a surprisingly under-reported story from 2007, Mark Holley, a professor of underwater archaeology at Northwestern Michigan University College, discovered a series of stones – some of them arranged in a circle and one of which seemed to show carvings of a mastodon – 40-feet beneath the surface waters of Lake Michigan.

"If verified, the carvings could be as much as 10,000 years old – coincident with the post-Ice Age presence of both humans and mastodons in the upper midwest...."

"Under-reported" is a matter of opinion. A story ran in the Duluth News Tribune (Thursday, September 6, 2007, p. 7): "Team find possible mastodon carving on Lake Michigan rock" (Thanks for posting the reference, to University of Minnesota, Duluth), and in quite a number of more-or-less breathless other publications.

The key phrase seems to be "if verified." So far, that doesn't seem to have happened. If, or when, the Michigan Stonehenge turns out to be a significant archeological site, my guess is that news of it will show up on Lake Michigan Underwater Archaeology Group, a part of learnarcheology.com that's facilitated by Dr. Mark Holley
