In Grand Traverse Bay, an arm of Lake Michigan (USA), a prehistoric structure resembling the English Stonehenge was discovered.
As reported in Arkeonews, it was found by the famous underwater archaeologist and professor at the Northwestern University of Michigan, Mark Polley
Grand Traverse Bay has a long history: data on shipwrecks testify to busy maritime trade routes in the 19th and 20th centuries. Their secrets attract the attention of many archaeologists and historians.
With the help of sonar at a depth of more than 12 meters, archaeologists discovered sunken boats, cars and even a pier dating back to the Civil War.

During the search, they also found a rock with a prehistoric carving of a mastodon, as well as a collection of stones laid out in a line more than one and a half kilometers long.
According to scientists, the age of the stones is nine thousand years, they appeared four thousand years before the construction of Stonehenge and about two thousand years after the end of the ice age. This happened when the bottom of the lake was dry, even before the appearance of Grand Traverse Bay.
Some of the scientists assume that the image of a mastodon is carved on the stones. However, this fact has not been confirmed yet.
“The structure discovered in Grand Traverse Bay can best be described as a long line of stones that extends for 1.6 kilometers,” said Dr. Holly.
However, this is not the only prehistoric submerged site in this region. While exploring Lake Huron, one of North America’s five Great Lakes, underwater archaeologists have also discovered traces of an ancient lost civilization that is twice as old as Stonehenge.

Dr. John O’Shea of the University of Michigan worked on a similar structure that was discovered in Lake Huron. He concluded that this structure was ideal for caribou hunting corridors (the practice of tracking and killing caribou reindeer for food, fur, or sport hunting).
Underwater archaeologists have discovered structures similar to a land corridor: it once connected northeastern Michigan and southern Ontario. Scientists say that this is the most complex hunting structure discovered under the Great Lakes. It consists of two parallel lines of stones. If the researchers’ conclusions are correct, then the hunting complex is twice as old as Stonehenge.
It is possible that the structure in Grand Traverse Bay may have served the same function as the line of rocks in Lake Huron.
Underwater archaeologist Mark Polley did not say exactly where the prehistoric structure was found, out of respect for the people who live in the region, and to prevent accidental destruction of the monument.
It will be recalled that a sunken ship more than 150 years old was discovered in the USA.
