Vortex Island (63°44′S 57°38′W / 63.733°S 57.633°W / -63.733; -57.633) is an island 0.5 nautical miles (0.9 km) long and 245 m high, lying in the northeast part of Prince Gustav Channel about 2 nautical miles (3.7 km) west-southwest of Corry Island, close south of Trinity Peninsula.
Islands in this area were first seen by a party under J. Gunnar Andersson of the Swedish Antarctic Expedition, 1901–04.
The FIDS survey party was forced to lie idle there by a whirlwind snowstorm, thus suggesting the name.
[1] Vortex Island is composed of Pleistocene volcanic rocks of the James Ross Island Volcanic Group, consisting of a tuya or moberg, which is a volcano erupted under an icecap.
