After decades of research, a group of enthusiasts finally discovers the sunken ship of Lake Michigan lost since 1886.

The shipwreck of Lake Michigan named F.J. King had haunted the minds of shipwreck hunters for decades. This 44-meter wooden three-master had sunk in 1886 during a storm, loaded with iron ore. Several generations of divers and historians had tried to find it, to no avail. In June 2025, a team of twenty volunteers from the Wisconsin Underwater Archaeology Association located it in just two hours, thanks to a method as simple as it was effective.

The shipwreck of Lake Michigan had resisted searches for over fifty years

The shipwreck of Lake Michigan, nicknamed the phantom ship, owed its reputation to its elusive nature. Since the 1970s, numerous expeditions had failed to find it. Local fishermen claimed to have pulled up pieces of the wreck in their nets. A diving club had even offered a reward of $1,000 for its discovery. However, shipwreck hunters always returned empty-handed. According to an article published by Popular Mechanics, the issue lay in the source used by all previous researchers.

They all relied on the report of Captain William Griffin, written in the dark of the night of the sinking. However, Griffin had given his position in complete darkness, at two in the morning, amidst violent winds and three-meter waves. His description was likely inaccurate. Maritime historian Brendon Baillod, and president of the WUAA, concluded that they needed to look elsewhere.

The shipwreck of Lake Michigan resurfaces thanks to a nineteenth-century lighthouse keeper’s notes

Baillod sifted through hundreds of archive documents on the shipwreck. He found the testimony of William Sanderson, the Cana Island lighthouse keeper. a few days after the sinking, Sanderson reported seeing the masts of the F.J. King above water, in a location closer to the shore than Griffin had indicated. Based on an analysis by the Wisconsin Underwater Archaeology Association, Baillod chose to trust the lighthouse keeper over the captain. He mapped out a search grid of two square miles around the point indicated by Sanderson.

On June 28, 2025, the team deployed a side-scan sonar, an instrument that maps the seabed with sound waves. On the second pass, a 44-meter object appeared on the screen. Remotely operated underwater vehicles, or ROVs, were sent to confirm the identification. The hull of the F.J. King was there, remarkably intact, less than a kilometer from the location described by Sanderson.

The shipwreck of Lake Michigan now enters the historical heritage of Wisconsin

The discovery surprised the team itself. Baillod admitted that he considered the search as an educational exercise to learn how to handle sonar, without real hope of success. Yet, this was the fifth significant shipwreck his team located in three years in the Great Lakes. In March 2026, the F.J. King was listed on the historical register of the state of Wisconsin.

The Great Lakes harbor about 6,000 documented commercial shipwrecks. In Lake Michigan alone, over 200 remain to be discovered. Therefore, Baillod’s method of combining historical archives with modern sonar and ROV technologies could inspire other teams. It proves that a forgotten document in a local 19th-century newspaper is sometimes more valuable than decades of fruitless searches.
