Chaos Reef

Chaos Reef is the confused area of breakers and shoal water in the north extremity of Aitcho Islands group on the west side of English Strait in the South Shetland Islands, Antarctica. The area was visited by early 19th century sealers operating from nearby Clothier Harbour.

Following a survey by the 1949 Chilean Antarctic Expedition, the feature was resurveyed and descriptively named from HMS Protector in 1967.
