Photo Gallery

The rectangular peninsula at the top of this Space Shuttle image of Erromango Island with north approximately to the left is the Traitor's Head Peninsula. It lies north of Cook Bay, named for Captain Cook, who actually landed at Polenia Bay on the other side of the peninsula. Three Holocene volcanic cones at Traitor's Head are the youngest on the 50-km-long island. The volcanoes initially formed an offshore island that was later joined to the mainland by uplift. The only historical activity at Erromango was a submarine vent that erupted in 1881.
