The wreck of Mary Alice B. rests in Lake Michigan, offering divers a glimpse into Great Lakes maritime history. The wooden steamer sits upright at 50 feet, with intact hull structure and machinery visible. Schools of freshwater fish like perch and bass surround the wreck, while zebra mussels cover the wooden beams. Visibility varies seasonally, often reaching 30 feet. The shallow depth makes it accessible for divers of all levels. Cold water requires proper thermal protection year-round. Nearby currents can be strong, so check conditions before diving. The site provides a well-preserved wreck dive with historical significance in the Great Lakes region.
