Kaska Lake (Bulgarian: езеро Каската, romanized: ezero Kaskata, IPA: ['ɛzɛro 'kaskɐtɐ]) is the 220 m long in west–east direction and 115 m wide lake on Triangulation Beach, Nelson Island in the South Shetland Islands, Antarctica. It has a surface area of 1.85 ha and is separated from the waters of Bransfield Strait by a 12 to 38 m wide strip of land. The area was visited by early 19th century sealers.[1]
The feature is so named because of its shape supposedly resembling a combat helmet ('kaska' in Bulgarian).
