Ginkgo Tarn (Bulgarian: езеро Гинкго|ezero Ginkgo, in Bulgarian pronounced as /'ɛzɛro 'ginko/) is the lake extending 140 m in southeast–northwest direction and 100 m in southwest–northeast direction on Long Beach, Nelson Island in the South Shetland Islands, Antarctica. It has a surface area of 1.5 ha and drains westwards into Platno Lake by way of a 250 m long stream. The area was visited by early 19th century sealers.[1]
The feature is so named because of its shape supposedly resembling a ginkgo tree leaf.
