Mooring Buoy Data

Description: The steamer Shamrock, loaded with lumber, sprang a leak off Presque Isle. The derelict steamer was towed to Alpena, where it sank at a waterfront pier. Heavy seas in the days that followed tore the partially sunken vessel to pieces. The hulk was then moved out of the way of navigation and abandoned within a few hundred feet of another shipwreck, John F. Warner. Today, both wrecks sit in less than 15 feet of water and are easily accessible.
