Bikorn Lake (Bulgarian: езеро Бикорна|ezero Bikorna, in Bulgarian pronounced as /'ɛzɛro bi'kɔrnɐ/) is the lake occupying most of the interior of Treklyano Island off the northeast coast of Robert Island in the South Shetland Islands, Antarctica. It extends 205 m in west-northwest to east-southeast direction and 137 m in south–north direction, with a surface area of 1.46 ha, and is separated from the waters of Nelson Strait by a 21 to 70 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 bicorne hat ('bikorn' in Bulgarian).
Bikorn Lake is centred at -62.3681°N -59.4088°W,[2] which is 3.18 km east of Ugarchin Point and 1.58 km west of Smirnenski Point. British mapping of the area in 1968 and Bulgarian in 2009.
