Site details

The package freighter America ran onto a reef in the North Gap of Washington Harbor in June 1928 and slid down the slope, where she lies on an incline with her bow just 2-4 ft below the surface and her stern at about 85 ft. The midship and stern remain intact, including the engine room, galley, and numerous passenger cabins, making her the most dived and most beloved wreck at Isle Royale — visible even to ferry passengers passing overhead. Her sheltered location makes her divable in most weather.
