Mount Everest, at 8,848 metres (29,029 ft) is the world's highest mountain and a particularly desirable peak for mountaineers.

Over 300 people have died trying to climb it. The last year without known fatalities on the mountain was 1977, a year in which only two people reached the summit.[1]

Most deaths have been attributed to avalanches, injury from fall, ice collapse, exposure, frostbite, or health problems related to conditions on the mountain. Not all bodies have been located, so details on those fatalities are not available.
The upper reaches of the mountain are in the death zone.

The death zone is a mountaineering term for altitudes above a certain point – around 8,000 m (26,000 ft), or less than 356 millibars (5.16 psi) of atmospheric pressure – where the oxygen level is not sufficient to sustain human life.[2]

Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly (loss of vital functions) or indirectly (unwise decisions made under stress or physical weakening leading to accidents).

In the death zone, the human body cannot acclimatize, as it uses oxygen faster than it can be replenished. An extended stay in the zone without supplementary oxygen will result in deterioration of bodily functions, loss of consciousness and, ultimately, death
