Below are pictures of the wreck of the City Of Glasgow, a ship which ran aground in 1917 off the Lake Michigan shore of Door County, Wisconsin and was abandoned. Over the years, due to water and ice, the top of the ship has been sheered off, exposing the deck substructure just below the surface.
The City Of Glasgow was a wooden steamship built in 1891, originally 297 feet long with a 41 foot beam. About half of the bow end is still intact and visible.
The waviness is due to the optical distortion of the water surface, since these pictures were taken above water.
