This beautiful Nat Geo map shows the routes of historic and modern Antarctic explorers. Greyscale routes are historic: Roald Amundsen, the first man to reach the South Pole; his British competition, Robert Falcon Scott; legendary explorer Ernest Shackleton; and the British Trans-Antarctic Expedition, which was the first overland crossing of the continent. Colored routes are modern: Borge Ousland, the first to cross the continent unaided by mechanical equipment; Cecilie Skog and Ryan Waters, the first to cross the continent unaided by any equipment; and Henry Worsley, who died after an attempt to be the first person to mimic Skog and Waters' feat solo.
