Chilling last photos of people before they went missing

In 2001, Frenchman Marco Siffredi made history when he became the first man to snowboard down Mount Everest via the Norton Couloir, a gorge running down the mountain’s northern face. Amazing as that is, Siffredi wasn’t pleased – he wanted to snowboard down the Hornbein Couloir to the west of the summit, but there wasn’t enough snow.

Undeterred, he returned the following year. After more than 12 hours of climbing, Siffredi reached the summit but was exhausted and possibly disoriented from altitude sickness. This photo was snapped just before he took off down the mountain, and was never seen again.
