Beneath the calm waters of Grand Traverse Bay, a remarkable discovery has stirred excitement. Known for its serene beauty and rich history, the bay now conceals an ancient mystery. Divers often find shipwrecks here, remnants of a bustling maritime past. However, the recent focus is on something much older.
Dr. Mark Holley, an underwater archaeology professor at Northwestern Michigan University, made a stunning find during a sonar scan. He discovered a series of large stones on the lake bed, leading many to call it "Michigan’s Stonehenge." This finding ignites curiosity about the area’s forgotten history.
About 40 feet down, a unique arrangement of stones stretches over a mile. While smaller than its British counterpart, the design of these stones—ranging from basketball size to the size of compact cars—suggests careful planning. They form a serpentine trail that raises questions about their origin.
Among the stones, one remarkable boulder stands about 3.5 feet tall and 5 feet wide, featuring a carved image of a mastodon. This carving connects the site with a time when ancient humans and these massive creatures coexisted. This unique detail not only intrigues researchers but also provides a glimpse into North America’s early culture.
Experts believe these stones were placed around 9,000 years ago, right after the last Ice Age. Back then, the waters of Grand Traverse Bay hadn’t yet risen to cover the land, making this site even older than England’s Stonehenge.
The bay itself measures 32 miles long and 12 miles wide, drawing divers and history buffs eager to explore its sunken treasures. Yet, few are aware of the ancient marvel lying beneath the waves. To ensure its preservation, Dr. Holley informed the Grand Traverse Band of Ottawa and Chippewa, respecting their ancestral ties. The exact location is kept secret to protect it from potential damage.
Researching this underwater site poses challenges. Since its discovery in 2007, progress has been slow, inviting much speculation about its significance. Other nearby stone structures might offer clues. For example, Dr. John O’Shea from the University of Michigan has examined a similar formation in Lake Huron, thought to be about the same age. This particular site may have been used by ancient hunters to channel migrating caribou.
Beaver Island, the largest island in Lake Michigan, also features ancient stone arrangements, like a circle of glacial boulders etched with inscriptions. One of these stones even bears a carved hole, hinting at its functional use during prehistoric times.
While we currently lack formal analyses like carbon dating, these stones likely held meaning for the Native American communities that resided in the area. They may have served as markers for celestial events or calendars, similar to their counterparts in England.
The purpose of the Grand Traverse Bay stone arrangement remains open to interpretation. Was it used by early hunters or perhaps as a calendar? As researchers continue their work, advanced technology in underwater exploration will play a crucial role in revealing the secrets of these ancient structures.
In the years ahead, we are likely to uncover more about Grand Traverse Bay’s past. By studying these artifacts and respecting their history, we will deepen our understanding of the people who once thrived in this region and honor their legacy.
