Mount Everest

Mount Everest is the highest mountain on Earth, as measured by the height of its summit above sea level, which is 8,848 metres (29,029 ft)। The mountain, which is part of the Himalaya range in High Asia, is located on the border between Sagarmatha Zone, Nepal, and Tibet, China।

The highest mountain in the world attracts climbers of all levels, from well experienced mountaineers to novice climbers willing to pay substantial sums to professional mountain guides to complete a successful climb. The mountain, while not posing substantial technical climbing difficulty on the standard route (other eight-thousanders such as K2 or Nanga Parbat are much more difficult), still has many inherent dangers such as altitude sickness, weather and wind. By the end of the 2007 climbing season, there had been 3,679 ascents to the summit by 2,436 individuals. Climbers are a significant source of tourist revenue for Nepal, whose government also requires all prospective climbers to obtain an expensive permit, costing up to US$25,000 per person.[4] Everest has claimed 210 lives, including eight who perished during a 1996 storm high on the mountain. Conditions are so difficult in the death zone that most corpses have been left where they fell, some of which are visible from standard climbing routes.

Mt. Everest has two main climbing routes, the southeast ridge from Nepal and the northeast ridge from Tibet, as well as many other less frequently climbed routes.[27] Of the two main routes, the southeast ridge is technically easier and is the more frequently-used route. It was the route used by Edmund Hillary and Tenzing Norgay in 1953 and the first recognised of fifteen routes to the top by 1996.[27] This was, however, a route decision dictated more by politics than by design as the Chinese border was closed to the western world in the 1950s after Communist China took over the control Tibet from the Republic of China.Most attempts are made during May before the summer monsoon season. As the monsoon season approaches, a change in the jet stream at this time pushes it northward, thereby reducing the average wind speeds high on the mountain.[29][30] While attempts are sometimes made after the monsoons in September and October, when the jet stream is again temporarily pushed northward, the additional snow deposited by the monsoons and the less stable weather patterns (tail end of the monsoon) makes climbing more difficult.
