Imagine cruising the serene waters of Lake Michigan, only to stumble upon a piece of history frozen in time, nearly 140 feet below the surface. That's exactly what happened to James Brodeur, a Milwaukee-area boater with a keen eye for sonar, whose chance discovery has rewritten a chapter of the Great Lakes' rich maritime past.
In the spring of 2021, while exploring off the coast of Port Washington, Wisconsin, Brodeur's sonar equipment picked up an unusual anomaly.
Initially, he suspected it might be a large rock or a glacial erratic, common in the lakebed. However, a closer look at the sonar images sparked a thrilling realization: the distinct outline suggested a vessel, remarkably intact. Knowing the immense historical potential of such a find, Brodeur promptly contacted the Wisconsin Historical Society (WHS).
What followed was a meticulous investigation by WHS maritime archaeologists, led by the renowned Tamara Thomsen.
In March 2022, equipped with remotely operated vehicles (ROVs) and divers, the team descended into the cold, dark depths. Their suspicions were dramatically confirmed: not only was it a shipwreck, but it was the remarkably preserved schooner, the Trinidad, which had vanished beneath the waves a staggering 141 years prior.
Built in 1867 in Grand Haven, Michigan, the Trinidad was a 140-foot workhorse of the Great Lakes, primarily ferrying goods across its vast expanse.
Its final voyage began on May 13, 1881, departing Chicago bound for Milwaukee with a critical cargo of coal. The lake, however, had other plans. Caught in a brutal spring gale that brought strong winds and heavy snow, the schooner was battered mercilessly. Its pumps failed, and with water rapidly filling the hold, the captain and crew were forced to abandon ship.
Miraculously, they were all rescued by another passing vessel, the Hunter, leaving the Trinidad to succumb to the tempest and sink to its watery grave.
The deep, cold, and dark freshwater environment of Lake Michigan proved to be an exceptional preserver. Unlike wrecks in saltwater, freshwater deters destructive shipworms and limits organic decay.
The Trinidad was found upright on the lakebed, its mast still standing, the anchor in place, and its deck house astonishingly intact. Even the valuable cargo of coal remained in its hold, a testament to the abruptness of its sinking. Personal effects, including boots and dishes, were still visible, offering a poignant glimpse into the lives of the sailors who once called this vessel home.
Archaeologists have hailed the Trinidad as a true .
