Alexander Island

Alexander Island is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula, from which it is separated by Marguerite Bay and George VI Sound.

Alexander Island is about 390 kilometers long in a north–south direction, 80 kilometers wide in the north, and 240 kilometers wide in the south. Alexander Island is the second largest uninhabited island in the world, after Devon Island. George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.
