Ever wonder what’s under the surface of Lake Michigan? Recent ice thaws have left the lake crystal clear, revealing some of the many shipwrecks it’s seen through the years.

In what they dubbed “Shipwreck Sunday,” the Facebook account for the U.S. Coast Guard Air Station Traverse City shared multiple photos of shipwrecks.

The photos were obtained during a routine patrol on Friday, April 17th. Most of the photos were taken along the Lake Michigan shoreline near Sleeping Bear Point in Michigan.
