CHICAGO (CBS) — Chicagoans can get an up-close look at shipwrecks sunk far below the surface of Lake Huron, hundreds of miles away, without ever leaving the Windy City, thanks to new 3-D models of the ships.

For years, people have flocked to Thunder Bay National Marine Sanctuary on Lake Huron in Northeast Michigan, to get a view of sunken ships.

“We estimate there’s at least 200 of these historic shipwrecks in and around the sanctuary, and these shipwrecks range from your old wooden schooners – dating back to the early 1800s – up to huge steel freighters,” said marine archaeologist Stephanie Gandulla.

Visitors can take a glass bottom boat tour to see the wrecks on the lake floor, but now people who can’t make the six-hour drive from Chicago to Thunder Bay can go online to see 3-D models off the sunken ships.

Marine archaeologists used new photo software technology to create the 3-D views.

“It just comes to life in those 3-D models,” Gandulla said. “It is nice and clear, and it’s really like you’re looking at the shipwreck under the water.”
