Site Description: The remains of the Chisholm and the Cumberland now lie intermixed in the ravine on the southwest end of Rock of Ages Reef at Isle Royale, Lake Superior. The most intact sections are the sides and bottom of the Chisholm. The Chisholm engine and rudder settled on the side of the shoal in 70ft to 150 ft of water. The engine is a double expansion steam engine sitting upright on the engine bed and the bottom of the stern of the ship. The thrust bearing, shaft, propeller and rudder are also on site although the rudder is in 70 ft of water above the engine on the shoal wall. Many artifacts lie on the broken side of the ship in deep water including a large wrench.
