Cold-water Lake Superior wreck with shore access and sparse life.
Cold-water Lake Superior wreck with shore access and sparse life.
SS Hesper (Wreck) is a shore-accessible Lake Superior wreck in Silver Bay Harbor, split into two main sections along the breakwall. The appeal is the structure itself: a cold-water wreck with easy staging from the marina, a mooring near the stern, and a conservative profile that rewards calm buoyancy and planning. Wildlife is sparse, with gobies and the occasional trout or whitefish in the area.
