Site details

Light Vessel No. 57, a 90-ft wooden lightship built in Toledo in 1891, served Lake Michigan stations until 1924, when it was sold for scrap and abandoned off Milwaukee. Its remains — the only known lightship wreck in Wisconsin waters, NRHP-listed in 1996 — lie mostly buried in silt in 6-12 ft of water about 600 ft south of the north tip of South Shore Park. An easy if low-relief shore dive/snorkel with sections of oak hull protruding from the sediment.
