The SS Clifton, originally launched as SS Samuel Mather in 1892, is a notable example of a whaleback lake freighter built for service on the Great Lakes. Constructed by the American Steel Barge Company in West Superior, Wisconsin, she measured approximately 308 feet (94 meters) in length, with a beam of 30 feet (9.1 meters) and a depth of 24 feet (7.3 meters). Her design was optimized for transporting iron ore, featuring a distinctive curved hull that resembled a whale's back when fully loaded, a hallmark of the whaleback vessel type designed by Captain Alexander McDougall. The vessel's capacity was around 3,500 tons, and she was powered self-propelled, a typical feature of her class. Initially serving as an ore carrier, the Samuel Mather operated for 31 years before being retired from iron ore transport. In 1923–1924, she was extensively refitted to carry stone aggregate, which included the installation of topside self-unloading gear with Smith-patented tunnel scrapers. This machinery was intended to expedite unloading operations and enable her to serve ports previously inaccessible to similar vessels. However, this modification added significant weight above her centerline, raising concerns about stability. On the night of September 21–22, 1924, while en route from Sturgeon Bay to Detroit with crushed stone, the Clifton encountered a severe storm on Lake Huron near Saginaw Bay. The vessel sank suddenly, with no survivors and no mechanical failure identified as the cause. Wreckage, including painted sticks, hatch covers, and parts of the pilot house, was scattered across a wide area, and the ship was presumed to have been overwhelmed by a large wave or waves, as evidenced by the damage to the hull and the position of the wreck on the lake bottom. The bow was found to be heavily damaged, consistent with a powerful impact during sinking. The sinking of the Clifton is shrouded in mystery, with early speculation implicating her self-unloading gear, but recent discoveries and analysis support the theory that she was broadsided by a large wave, causing her to founder rapidly. Her wreck was only located in September 2016, discovered by deep-sea divers led by maritime archeologist David Trotter, who confirmed her identity in 2017. The site rests at a 45-degree angle on the lakebed, heavily on her port side, indicating she was struck broadside. The loss of the Clifton remains a significant maritime tragedy, remembered not only for her unique design but also as a symbol of the deadly storms that have claimed many vessels on the Great Lakes.
