Black Island (Ross Archipelago)

Black Island (78°14′S 166°20′E), in the Ross Archipelago, is immediately west of White Island. It was first named by the Discovery Expedition (1901–04) because of its lack of snow. The island's northernmost point is named Cape Hodgson, commemorating Thomas Vere Hodgson.[1]
