Beneath the ice sheet which covers it , the Antarctic ___MASK27___ consists of a string of bedrock islands ; these are separated by deep channels whose bottoms lie at depths considerably below current sea level . They are joined together by a grounded ice sheet . Tierra del Fuego , the southernmost tip of South America , lies only about away across the Drake Passage . Atherton Peak is a peak rising to about east of Fortuna ___MASK70___ , South Georgia . It was charted by Discovery Investigations , 1929  30 , and named after Noel Atherton , cartographer in the Admiralty Hydrographic Office at the time , later chief Civil Hydrographic Officer , 1951  62 .
