Lion Island is an island 1.5 nautical miles (2.8 km) long and 1 nautical mile (1.9 km) wide, lying off the east side of Anvers Island and 1 nautical mile (1.9 km) northeast of Cape Astrup, Wiencke Island, in the Palmer Archipelago off the Antarctic Peninsula.[1]
It was discovered by the Belgian Antarctic Expedition, 1897–1899, under Adrien de Gerlache. The name appears on a map based on a 1927 survey by Discovery Investigations personnel on the RRS Discovery. The profile of the island suggests a reclining lion when viewed from the southwest.
