South side, towards the west, W83 deg 09 min, N45 deg 08 min, just above
the box for the Alpena VORTAC. Is that a shipwreck with mast sticking up,
or what? Seems that the water would be too deep there for a mast to be
visible. I can't remember ever seeing that symbol before. Anyone?


The symbol means exposed wreck.
