Dr. Mark Holley, professor of underwater archaeology at Northwestern Michigan University, announced the discovery of an ancient structure beneath Grand Traverse Bay in Lake Michigan (USA), according to The Brighter Side of News on January 11.

Nicknamed the "Stonehenge of Michigan," the structure sits about 40 feet below the surface of Lake Michigan. While smaller than Stonehenge in England, the stones at the bottom of the lake are carefully arranged, suggesting that the ancients put some thought into the construction of the complex.

Stretching over 1.6 km, the complex includes rocks of different sizes, from as small as a ball to as large as a car.

One rock in particular caught the researchers’ attention. Measuring 5 feet wide and 4 feet high, the rock is carved with the image of a mastodon, providing a rare glimpse into when this animal was still present in Michigan.

The Mastodon Stone Carvings bridge the gap between human history and the prehistoric world , and deepen the mysteries of Grand Traverse Bay.

The ancient rock formations at the bottom of Lake Michigan are estimated to be around 9,000 years old, 4,000 years older than Stonehenge in England. This period followed the end of the Ice Age and the formation of Grand Traverse Bay, when the lakebed had not yet sunk and become submerged.

It is still unclear why the ancient people built the stone structures in Grand Traverse Bay. According to some theories, prehistoric people may have arranged the stones for hunting purposes, or they may have used them as an ancient calendar, based on astronomical events like at Stonehenge.
