The Great Lake has an even bigger mystery.
Dozens of massive 600-foot-wide craters have recently been discovered 500 feet below Lake Michigan, but how they got there remains a wonder.
Back in 2022, the Wisconsin Shipwreck National Marine Sanctuary discovered this anomaly through sonar. Last month, a new, remote expedition was sent to its water division 14 miles southeast of Sheboygan, Wisconsin. Live Science reported.
“There is now a geological question to consider. How did they form? Why are they there, specifically in the rock?” Wisconsin Maritime Museum Director Kevin Cullen He told TMJ4 News.
“We're all scratching our heads wondering, what could these things be?”
For now, Cullen, who notes that only 10 to 15 percent of Lake Michigan's vast bottom has been explored, hails a possible connection to underwater valleys formed by glaciers centuries ago.
However, local shipwreck hunter Brendon Billaud told LiveScience that he is not yet ready to call the underwater phenomena sinkholes.
“I think they could be more accurately called craters,” Baillod said, explaining that they may be the result of trapped gas or water flowing toward the surface.

Now, Colin is embracing the mystery and what could come from more research into the less-understood area.
“This is the beauty of storytelling, and the beauty of scientific research,” he said. “There are always new gems to discover.”
