The Icefall Doctors reach a huge crevasse blocking their route – a cleft in the ice 50 metres deep, with no way round.
Everest is the world’s highest mountain, at nearly 9,000 metres if you measure from sea level. Mount Everest attracts many highly experienced mountaineers as well as capable climbers willing to hire professional guides. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the standard route) and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, wind as well as significant objective hazards from avalanches and the Khumbu Icefall.
