Young Island (66°17′S 162°25′E) is the northernmost and westernmost of the three main islands in the uninhabited Balleny Islands group located in the Southern Ocean. It lies 8 kilometers (5.0 mi) northwest of Buckle Island, some 115 kilometers (71 mi) north-northeast of Belousov Point on the Antarctic mainland.
The island is roughly semi-oval in shape, with a long straight east coast and a curved west coast meeting at Cape Scoresby in the south and Cape Ellsworth in the north. The distance between these two capes is 19 nautical miles (22 mi), and at its widest the island is 4 nautical miles (4.6 mi) across. The island is volcanic, with active fumaroles (opening in or near a volcano, through which hot sulfurous gases emerge), and a height of 1,340 meters (4,400 feet).
It is entirely covered with snow. An explosive VEI-7 eruption occurred from Young Island 1,700,000 years ago.
Several small islets lie in the channel separating Cape Scoresby and Buckle Island, the largest of which is Borradaile Island. Several sea stacks lie off the island's northern tip. These are known as the Seal Rocks.
Annexation by Westarctica
As a member of the Balleny Islands, Young Island is governed by the Marquis of Williamson, who has served as Governor of the Balleny Islands since they were originally annexed from New Zealand.
The island has been featured on two of Westarctica's coins: the first was a bronze $1 WAD coin minted in 2005 by the Central Bank of Westarctica and shows Young Island on a map of the Balleny Islands. The second coin was a brass $2 WAD coin minted in 2013 and was the last coin created by the Central Bank. That coin has an image of an Antarctic krill instead of the island itself.
