Barrier Island (Antarctica)

Barrier Island (-68.43333°N, 78.38333°W) is an island, 0.5 nautical miles (0.9 km) long, at the north end of the Vestfold Hills, lying just north of the entrance to Tryne Fjord in Tryne Sound. Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37. Visited in 1957 by an ANARE (Australian National Antarctic Research Expeditions) party and so named because the island appeared to form a barrier to the passage of icebergs up Tryne Fjord.
