The first recorded efforts to reach Everest's summit were made by British mountaineers. As Nepal did not allow foreigners to enter the country at the time. After the first reconnaissance expedition by the British in 1921 reached 7,000 m (22,970 ft) on the North Col, the 1922 expedition pushed the north ridge route up to 8,320 m (27,300 ft), marking the first time a human had climbed above 8,000 m (26,247 ft). The 1924 expedition resulted in one of the greatest mysteries on Everest to this day: George Mallory and Andrew Irvine made a final summit attempt on 8 June but never returned, sparking debate as to whether they were the first.
Mount Everest attracts many climbers, including highly experienced mountaineers. 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, and wind, as well as hazards from avalanches and the Khumbu Icefall. As of 2019, over 300 people have died on Everest,[4] many of whose bodies remain on the mountain.
The 1996 Mount Everest disaster occurred on 10–11 May 1996 when eight climbers caught in a blizzard died on Mount Everest while attempting to descend from the summit. Over the entire season, 12 people died trying to reach the summit, making it the deadliest season on Mount Everest at the time and the third deadliest after the 22 fatalities resulting from avalanches caused by the April 2015 Nepal earthquake[1] and the 16 fatalities of the 2014 Mount Everest avalanche. The 1996 disaster received widespread publicity and raised questions about the commercialization of Everest.
