The Cumberland was a wooden side-wheel passenger steamer that grounded on Rock of Ages Reef at Isle Royale's western tip in July 1877 and broke up. Large sections of her wooden hull, her huge side-wheel, and a boiler lie in 20-80 ft, intermingled with wreckage of the steel freighter Henry Chisholm, which struck the same reef 21 years later. The two-wrecks-in-one site is a fascinating archaeology dive at moderate depth, though the reef is fully exposed to Lake Superior weather.
