Mark Holley, a professor of underwater archeology at Northwestern Michigan University, discovered a prehistoric structure in Grand Traverse Bay, an arm of Lake Michigan, that vaguely resembles the famous English Stonehenge. The age of the find is estimated at nine thousand years, Arkeonews reports..

The publication notes that the waters of Grand Traverse Bay are rich in history.. The remains of shipwrecks discovered here are a reminder that this region was a busy trade route in the 19th and 20th centuries.. Under its waters, at a depth of 12 meters, sunken boats and cars and even a pier from the time of the American Civil War have already been discovered.

In a new study, when scientists searched for shipwrecks at the bottom of the lake, they discovered a rock with a prehistoric image of a mastodon, as well as several stones whose arrangement resembled Stonehenge.

The discovered stones were lined up about 1.5 kilometers long.. The age of the stones is estimated at 9,000 years, that is, they were built 4,000 years before the appearance of Stonehenge and approximately two thousand years after the end of the Ice Age. The structure was built when the lake bottom was dry land, before the advent of Grand Traverse Bay..

“This region seems to appear in the media about every six months. Unfortunately, most of the information is incorrect. For example, there is no hedge at the site, and the individual stones are relatively small compared to what most people think of as European standing stones.

It should be clearly understood that this is not a megalith like Stonehenge. This label was posted on the site by members of the press who may have been trying to create a sensation for the story but did not visit the location. This location in Grand Traverse Bay can best be described as a long line of rocks over a mile long,” Dr. Holley said.

This isn't the only strange prehistoric region discovered in the area. While exploring Lake Huron, one of the five Great Lakes of North America, underwater archaeologists discovered traces of a prehistoric civilization twice as old as Stonehenge and the Egyptian pyramids.

John O'Shea of \u200b\u200bthe University of Michigan studied a similar structure from Lake Huron. He believes the arrangement of the rocks is ideal for caribou hunting corridors.

Archaeologists have found a land corridor that once connected northeastern Michigan and southern Ontario. The main feature found here, Drop 45 Drive Lane, is the most complex hunting structure discovered beneath the Great Lakes.

The 9,000-year-old limestone structure consists of two parallel rows of stones leading to a cul-de-sac paved with natural cobblestones. If the scientists' conclusions are correct, then this hunting complex is twice as old as Stonehenge.

It is possible that the Grand Traverse Bay find may have served a similar function to the Lake Huron assemblage.

Previously, archaeologists discovered a Neolithic monument in Bedfordshire, which puzzled scientists. It contains 25 monumental pits, far more than anywhere in England and Wales, including Stonehenge.
