Last spring en route to Mount Everest,
Hilaree O’Neill, a ski-mountaineer from Colorado who was part of our
2012 Everest expedition, trekked the same valleys and worked up to Base Camp just as Sir Edmund Hillary and Tenzing Norgay did 60 years ago when the duo claimed the first ascent. But on the mountain, fortunately, O'Neill did not use the antiquated gear—think woolen suits and wood-handled ice axes—that Hillary hauled. In this gallery, we take a look at the equipment Hillary and Norgay used in 1953 and the high-tech gear O'Neill will use to climb the world's tallest peak in 2012.
