Isle Royale National Park, Michigan - Chisolm, a bulk freighter built of wood, was built in 1880 and ran aground in the predawn hours of October 20, 1898. Large sections of the wooden hull lie scattered among the Cumberland wreckage on a reef not marked by the Rock of Ages Lighthouse. This site features an intact steam enging with drive shaft and propeller sitting in about 140’ of water. The double expansion steam engine stands about 20 feet tall and is near perfect condition framed in ornate iron work. The engine has two pistons, one 30" and the other 56" in diameter, that operated with a four foot stroke. - Steve Martin, ISRO Picture of the Day.
