Cause of Loss: collision with the propeller Ogdensberg. The Atlantic was a luxurious wooden side wheel steamer use for passenger and package freight. She is today the grave of 150 to 250 persons who died after the collision that brought her down with the freighter Ogdensburg that fatal night around 2h30AM. She was loaded with immigrants and valuables and was considered the fastest ship on the Great Lakes. It was carrying over 600 persons and is now resting south of Long Point. Numerous salvage attempts have been made starting in 1853. Even a midget submarine gave it a try. Her safe was recovered in 1856 by M.P. Harrington. Salvage efforts continued in 1854, 1855, 1873 and 1910.
It has been rediscovered in 1987 and two years later, an entrepreneurial dive group claimed salvage rights after finding it in 1989. According to them, it has more than one billion dollars of valuables aboard. A law suit was conducted by the Canadian government to protect her. The case ruled in favor of the government in 1996 after several years of litigation.
