Mary Alice B - Southwest Michigan Underwater Preserve, Michigan

Lake Huron claimed the 65-foot- long propeller tug in 1975 off Port Sanilac. The wreck now sits upright at a depth of more than 80 feet. Divers can explore around the machinery on the aft deck, the intact pilothouse and the wheel; penetration-trained divers can venture inside.Local Dive Guide: Cold Water, Advanced Dives, Small Animals, Guide Needed, Summer Trip
