>The site in Grand Traverse Bay is best described as a long line of stones which is over a mile in length.... Dr. John O’Shea from University of Michigan has been working on a broadly similar structure over in Lake Huron... [He] thinks that it may be a prehistoric drive line for herding caribou.... It is highly possible that the site in Grand Traverse Bay may have served a similar function to the one found in Lake Huron.
So not like Stonehenge but seems interesting to me.
The "Stonehenge" reference is likely utilized as an imagery anchor that most people will recognize. Whereas the implication is that it is suspected that the possible structure under discussion and Stonehenge are similar because they both may be intentionally built megalithic structures (generally from the Neolithic). Of which there are a lot of worldwide examples that are in straight lines, as well as other configurations.
