The sunrise casts a gentle, orange glow on a mooring buoy marking one of the many shipwrecks that rest on the bottom of Thunder Bay National Marine Sanctuary. Scuba divers explore the pristine remains of a wooden schooner with masts still standing tall. History is well-preserved by the fresh, cold waters of this sanctuary, where lighthouses dot the shoreline, recreation opportunities are vast, and stories come to life.
