Site details

The scow-schooner Iris (1866) was deliberately run hard aground in Jackson Harbor, Washington Island, by its captain in March 1913. The hull lies upright and embedded in less than 4 ft of water between the Rock Island ferry dock and the Ellefson fishing piers, with stern structure protruding above the surface; the lower hull is partly buried under dredge spoil. A historic snorkeling and viewing site rather than a scuba dive — mind the adjacent ferry traffic.
