Sail Rock (South Shetland Islands)
Sail Rock, the remaining uppermost part of a submerged volcanic edifice, is 30 m high, and lies 7 nautical miles (13 km) southwest of Deception Island, in the South Shetland Islands. This name, which dates back to at least 1822, was probably given by sealers. From a distance, the rock is reported to resemble a ship under sail, but at close range it is more like a house with a gable roof.
In June 2016, the 'Daily Mail' published a satellite photo of the rock with the caption, "Has a KRAKEN been spotted on Google Earth?".[1] with theories that the rock might be a giant squid, a plesiosaur, an underwater UFO, and other unlikely theories.
