An untold number of shipwrecks rest on the bottom of the Great Lakes. Many of these were explored by earlier generations of divers but never identified. Improvements in visibility and technology have warranted a fresh look at some of these previously explored sites. There are several such shipwrecks in and around the Thumb Bottomland Preserve.

Join us as we use new technology and improved visibility to document and identify the Schooner Arctic. The shipwreck is resting within the Thumb Bottomland Preserve, close to other popular dive sites, and will be a great addition to the awesome dive sites, off the Thumb. Later in the summer, we make a long run offshore to explore a pristine, rarely dove, steamer. Upright and amazingly intact, this is a true Great Lakes treasure. And last, we visit a wreck found right below our noses. An amazingly intact wreck that sits within snorkeling depths just off Grindstone City, MI. The remains of this shipwreck have many design features of the typical utility Mackinaw sailing vessel used in the 1800s and early 1900s.
