Edmund Hillary, Edmund Shackleton, Marco Polo, and Neil Armstrong all accomplished feats that forever change humanity - breaking boundaries, redefining our limitations, and going where no one ever dared. But who was the greatest? We looked back at the feats of history's most prolific explorers on land, air, and ice, and picked our winners.
On Ice (Round 3)
Winner - Amundsen: He quickly overtook Scott in Antarctica, using experience gained from 11 polar winters. On December 14, 1911, the methodical Amundsen reached the South Pole, covering 714 miles in just 57 days with skis and sled dogs (which he had killed off in sequence to feed his other dogs, and men).
