Everest, the world's highest mountain at 29,029 ft above sea level, continues to exert an unyielding pull on the collective imaginations of would-be mountaineers. So far around 2,700 people have been recorded making it to the summit. But the conditions are unforgiving. Since 1953, there have been some 300 deaths on Everest. Many bodies have been brought down, but those above 8,000 meters have generally been left to the elements -- their bodies preserved by the freezing temperatures.
