Most people have heard of a bird or wildlife sanctuary, but fewer are familiar with sanctuaries for shipwrecks.

The Thunder Bay National Marine Sanctuary is one of only 14 national marine sanctuaries in the entire country operated by the National Oceanic and Atmospheric Administration, and it’s situated in the northwest corner of Lake Huron, just off the shores of Alpena.

A watery window to Michigan’s past is expanding.

The Thunder Bay National Marine Sanctuary is expanding from its present 448 square miles of Lake Huron to 4,300 square miles.

Jeff Gray is the sanctuary superintendent. He says the expanded sanctuary will protect hundreds of shipwrecks, many dating back to the 19th and early 20th centuries.

“Each one of these wrecks is a tragic tale of how it ended up on the bottom. But each one of those wrecks played its part in building the country,” says Gray.
