Transantarctic Mountains

The Transantarctic Mountains geologically divide Antarctica into east and west sections. The longest range in Antarctica, it stretches 2,500 miles across the entire length of the continent, passing roughly 300 miles west of the South Pole. Along its great length, the massive block-faulted mountains mingle with huge glaciers and small icy lakes. Though most of the range is continental, at one end it towers along the eastern shore of Ross Sea, and emerges from the icy offshore waters as Ross Island, home to twin volcanoes Mt. Erebus (12,447 ft.) and Mt. Terror (10,750 ft.).
