Mount Everest
============
Mount Everest, also called Sagarmatha or Chomolungma, Qomolangma or Zhumulangma, 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.
In 1856, the Great Trigonometric Survey of India established the first published height of Everest at 29,002 ft (8,840 m), although at the time Everest was known as Peak XV. In 1865, Everest was given its official English name by the Royal Geographical Society upon recommendation of Andrew Waugh, the British Surveyor General of India at the time. Waugh was unable to propose an established local name due to Nepal and Tibet being closed to foreigners at the time, although Chomolungma had been in common use by Tibetans for centuries.
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. This means 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. Everest has claimed 210 lives, including 15 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.

珠穆朗玛峰
=========
珠穆朗玛峰，简称珠峰，又意译作圣母峰，位于中国和尼泊尔交界的喜马拉雅山脉之上，海拔为8844.43米，终年积雪。是世界海拔第一高峰。藏语珠穆朗玛就是“大地之母”的意思，称作圣母峰。藏语“珠穆”是女神之意，“朗玛”应该理解成母象（在藏语里，“朗玛”有两种意思：高山柳和母象）。神话说珠穆朗玛峰是长寿五天女（tshe-ring mched lnga）所居住的宫室。
西方更多的称这山峰作额菲尔士峰或艾佛勒斯峰（Mount Everest），是纪念英国殖民者侵占尼泊尔之时，负责测量喜马拉雅山脉的英属印度测量局局长乔治·额菲尔士（George Everest）。尼泊尔语名是萨迦玛塔，意思是“天空之女神”。这名字是尼泊尔政府二十世纪六十年代起名的。由于此前，尼泊尔人民没有给这山峰起名，而政府由于政治原因没有选择用音译名称。
1258年出土的《莲花遗教》以“拉齐”称之，噶举派僧人桑吉坚赞《米拉日巴道歌集》称珠穆朗玛峰所在地为“顶多雪”。1717年，清朝测量人员在珠穆朗玛峰地区测绘《皇舆全览图》，以“朱姆朗马阿林”命名，“阿林”是满语，意思是“山”。1952年中国政府更名为珠穆朗玛峰。
1956年，中国中央人民政府内务部、出版总署通报“额菲尔士峰”应正名为“珠穆朗玛峰”。2002年，中国大陆《人民日报》发表了一篇文章，对西方世界继续使用的英文名称"额菲尔士峰"，应正名为其藏语名字"珠穆朗玛峰"。 该报认为，西方使用英语名称"额菲尔士峰"前280年前中国的地图上标志已以“珠穆朗玛”命名。台湾传统上一直以"圣母峰"称呼此山，并在教科书中采用此意译；近年来开始有人接受中国大陆"珠穆朗玛峰"的名称，但仍不普遍。
Mount Everest, mountain peak in the Himalayas of southern Asia, considered the highest mountain in the world. Mount Everest is situated at the edge of the Tibetan Plateau (Qing Zang Gaoyuan), on the border of Nepal and the Tibet Autonomous Region of China.
Mount Everest was known as Peak XV until 1856, when it was named for Sir George Everest, the surveyor general of India from 1830 to 1843. The naming coincided with an official announcement of the mountain's height, taken as the average of six separate measurements made by the Great Trigonometrical Survey in 1850. Most Nepali people refer to the mountain as Sagarmatha, meaning “Forehead in the Sky.” Speakers of Tibetan languages, including the Sherpa people of northern Nepal, refer to the mountain as Chomolungma, Tibetan for “Goddess Mother of the World.”
The height of Mount Everest has been determined to be 8,850 m (29,035 ft). The mountain’s actual height, and the claim that Everest is the highest mountain in the world, have long been disputed. But scientific surveys completed in the early 1990s continued to support evidence that Everest is the highest mountain in the world. In fact, the mountain is rising a few millimeters each year due to geological forces. Global Positioning System (GPS) has been installed on Mount Everest for the purpose of detecting slight rates of geological uplift.
Mount Everest, like the rest of the Himalayas, rose from the floor of the ancient Tethys Sea. The range was created when the Eurasian continental plate collided with the Indian subcontinental plate about 30 to 50 million years ago. Eventually the marine limestone was forced upward to become the characteristic yellow band on the top of Mount Everest. Beneath the shallow marine rock lies the highly metamorphosed black gneiss (foliated, or layered, rock) of Precambrian time, a remnant of the original continental plates that collided and forced up the Himalayas.
Mount Everest is covered with huge glaciers that descend from the main peak and its nearby satellite peaks. The mountain itself is a pyramid-shaped horn, sculpted by the erosive power of the glacial ice into three massive faces and three major ridges, which soar to the summit from the north, south, and west and separate the glaciers. From the south side of the mountain, in a clockwise direction, the main glaciers are the Khumbu glacier, which flows northeast before turning southwest; the West Rongbuk glacier in the northwest; the Rongbuk glacier in the north; the East Rongbuk glacier in the northeast; and the Kangshung glacier in the east.
The climate of Mount Everest is naturally extreme. In January, the coldest month, the summit temperature averages -36° C (-33° F) and can drop as low as -60° C (-76° F). In July, the warmest month, the average summit temperature is -19° C (-2° F). At no time of the year does the temperature on the summit rise above freezing. In winter and spring the prevailing westerly wind blows against the peak and around the summit. Moisture-laden air rises from the south slopes of the Himalayas and condenses into a white, pennant-shaped cloud pointing east; this “flag cloud” sometimes enables climbers to predict storms. When the wind reaches 80 km/h (50 mph), the flag cloud is at a right angle to the peak. When the wind is weaker, the cloud tilts up; when it is stronger, the flag tilts down.
From June through September the mountain is in the grip of the Indian monsoon, during which wind and precipitation blow in from the Indian Ocean. Masses of clouds and violent snowstorms are common during this time. From November to February, in the dead of winter, the global southwest-flowing jet stream moves in from the north, beating the summit with winds of hurricane force that may reach more than 285 km/h (177 mph). Even during the pre- and post-monsoon climbing seasons, strong winds may arise suddenly. When such storms develop, sand and small stones carried aloft, as well as beating snow and ice, pose problems for climbers.
Precipitation falls mostly during the monsoon season, while winter storms between December and March account for the rest. Unexpected storms, however, can drop up to 3 m (10 ft) of snow on unsuspecting climbers and mountain hikers.
Base Camp, which serves as a resting area and base of operations for climbers organizing their attempts for the summit, is located on the Khumbu glacier at an elevation of 5,400 m (17,600 ft); it receives an average of 450 mm (18 in) of precipitation a year.
Traditionally, the people who live near Mount Everest have revered the mountains of the Himalayas and imagined them as the homes of the gods. Because the peaks were considered sacred, no local people scaled them before the early 1900s. However, when foreign expeditions brought tourist dollars and Western ideas to the area, people of the Sherpa ethnic group began to serve as high-altitude porters for them. Because Nepal had been closed to foreigners since the early 1800s, all pre-World War II (1939-1945) Everest expeditions were forced to recruit Sherpa porters from Dārjiling (Darjeeling), India, then circle through Tibet and approach Everest from the north.
In 1913 British explorer John Noel sneaked into Tibet, which was also closed at the time, and made a preliminary survey of the mountain’s northern approaches, where the topography is less varied than on the southern side. In 1921 the British began a major exploration of the north side of the mountain, led by George Leigh Mallory. Mallory’s expedition, and another that took place soon afterward, were unable to overcome strong winds, avalanches, and other hazards to reach the summit. In 1924 a third British expedition resulted in the disappearance of Mallory and a climbing companion only 240 m (800 ft) from the summit. More attempts were made throughout the 1930s and into the 1940s. Then, with the conquest of Tibet by China in the early 1950s, the region was closed to foreigners again and the northern approaches to the mountain were sealed off.
In 1950, the year after Nepal opened to foreigners, W. H. Tilman and C. Houston made the first ascent from the south and became the first people to see into the Khumbu cirque (a steep basin at the head of a mountain valley). A number of attempts to reach the mountain’s summit followed in the early 1950s. In 1952 the Swiss almost succeeded in climbing the mountain from the South Col, which is a major pass between the Everest and Lhotse peaks and is now the most popular climbing route to the summit. On May 29, 1953, under the tenth British expedition flag and the leadership of John Hunt, Edmund Hillary of New Zealand and Sherpa Tenzing Norgay of Nepal successfully completed the first ascent of Mount Everest via the South Col. Several expeditions have since followed. In 1975 Junko Tabei of Japan became the first woman to summit Mount Everest. Later, in 1978, Austrians Reinhold Messner and Peter Habeler established a new and rigorous standard by climbing to the summit without the use of supplemental oxygen, which, because of the thin air at Everest’s high altitude, is important for the energy, health, and thinking skills of the climbers. In 1991 Sherpas, who had carried the supplies for so many foreigners up Mount Everest, completed their own successful expedition to the summit. By the mid-1990s, 4,000 people had attempted to climb Everest—660 of them successfully reached the summit and more than 140 of them died trying.
The difficulties of climbing Mount Everest are legendary. Massive snow and ice avalanches are a constant threat to all expeditions. The avalanches thunder off the peaks repeatedly, sometimes burying valleys, glaciers, and climbing routes. Camps are chosen to avoid known avalanche paths, and climbers who make ascents through avalanche terrain try to cross at times when the weather is most appropriate. Hurricane-force winds are a well-known hazard on Everest, and many people have been endangered or killed when their tents collapsed or were ripped to shreds by the gales. Hypothermia, the dramatic loss of body heat, is also a major and debilitating problem in this region of high winds and low temperatures.

Another hazard facing Everest climbers is the famous Khumbu icefall, which is located not far above Base Camp and is caused by the rapid movement of the Khumbu glacier over the steep rock underneath. The movement breaks the ice into sérac (large, pointed masses of ice) cliffs and columns separated by huge crevasses, and causes repeated icefalls across the route between Base Camp and Camp I. Many people have died in this area. Exposed crevasses may be easy to avoid, but those buried under snow can form treacherous snow bridges through which unwary climbers can fall.
The standard climb of Mount Everest from the south side ascends the Khumbu glacier to Base Camp at 5,400 m (17,600 ft). Typical expeditions use four camps above Base Camp; these camps give the climbers an opportunity to rest and acclimate (adapt) to the high altitude. The route from Base Camp through the great Khumbu icefall up to Camp I at 5,900 m (19,500 ft) is difficult and dangerous; it usually takes one to three weeks to establish because supplies must be carried up the mountain in several separate trips. Once Camp II, at 6,500 m (21,300 ft), has been supplied in the same manner using both Base Camp and Camp I as bases, climbers typically break down Base Camp and make the trek from there to Camp II in one continuous effort. Once acclimatized, the climbers can make the move to Camp II in five to six hours. Camp III is then established near the cirque of the Khumbu glacier at 7,300 m (24,000 ft). The route up the cirque headwall from Camp III to the South Col and Camp IV at 7,900 m (26,000 ft) is highly strenuous and takes about four to eight hours. The South Col is a cold, windy, and desolate place of rocks, snow slabs, littered empty oxygen bottles, and other trash.
Deadly Day on Mount Everest
Deadly Day on Mount Everest
In May 1996 a chain of amateur climbers and professional guides wait their turn to ascend the Hillary Step, a rock face, 12-m (40-ft) tall, (center) just 30 m (100 ft) below the summit of Mount Everest. This photograph was taken by guide Scott Fischer on what became one of the deadliest days ever on Mount Everest. Fischer and several other climbers perished just hours later when a sudden, severe storm trapped several climbing parties high on the mountain. In all, 12 climbers died. Some survivors and other observers believe that the tragedy was due in part to crowded summit conditions—there were simply too many climbers, especially less-experienced climbers, trying to summit Mount Everest at the same time.

From the South Col to the summit is a climb of only 900 vertical m (3,000 vertical ft), although its fierce exposure to adverse weather and steep drop-offs poses many challenges. The section between 8,530 m (28,000 ft) and the South Summit at 8,750 m (28,700 ft) is particularly treacherous because of the steepness and unstable snow. From the South Summit there remains another 90 vertical m (300 vertical ft) along a terrifying knife-edged ridge. The exposure is extreme, with the possibility of huge vertical drops into Tibet on the right and down the southwest face on the left. A little more than 30 vertical m (100 vertical ft) from the summit is a 12-m (40-ft) chimney across a rock cliff known as the Hillary Step; this is one of the greatest technical challenges of the climb.
As the popularity of climbing Everest has increased in recent years, so have safety problems. To pay the high climbing permit fee charged by the Nepalese government, many experienced climbers have recruited wealthy, amateur climbers as teammates. The combination of inexperience, crowded summit conditions (more than 30 have been known to summit the peak on the same day), and extreme weather conditions has led to a number of tragedies in which clients and competent guides alike have died attempting the climb.
The large number of trekkers and climbers who visit Nepal and the Everest region contribute to the local economy but also cause serious environmental impact. Such impact includes the burning of wood for fuel, pollution in the form of human waste and trash, and abandoned climbing gear. Although some climbing gear is recycled by local residents either for their own use or for resale, it is estimated that more than 50 tons of plastic, glass, and metal were dumped between 1953 and the mid-1990s in what has been called “the world’s highest junkyard.” Up on the ice, where few local people go, the norm is to throw trash into the many crevasses, where it is ground up and consumed by the action of the ice. A few bits and pieces show up on the lower part of the glacier many years later as they are churned back to the surface, although organic matter is generally consumed or scavenged by local wildlife. At the high-elevation camps, used oxygen bottles are strewn everywhere.
Efforts have been made to reduce the negative environmental impact on Mount Everest. The Nepalese government has been using a portion of climbing fees to clean up the area. In 1976, with aid from Sir Edmund Hillary’s Himalayan Trust and the Nepalese government, the Sagarmatha National Park was established to preserve the remaining soil and forest around Mount Everest. By the mid-1990s the park comprised 1,240 sq km (480 sq mi). Trekking and climbing groups must bring their own fuel to the park (usually butane and kerosene), and the cutting of wood is now prohibited. Because the freedoms of Sherpas have been restricted by the park rules, they have not been sympathetic to the existence of the park. Additionally, the Sagarmatha Pollution Control, funded by the World Wildlife Fund and the Himalayan Trust, was established in 1991 to help preserve Everest’s environment. Climbing activity continues to increase, however, and the environmental future of the Mount Everest area remains uncertain.
Mount Everest or Qomolangma or Sagarmatha or Chomolungma pronounced as is the highest mountain on Earth, as measured by the height of its summit above sea level. The mountain, which is part of the Himalaya range in High Asia, is located on the border between Nepal and China.
Naming
The ancient Sanskrit names for the mountain are Devgiri and Devadurga . In Nepali it is known as Sagarmatha meaning "Head of the Sky". The Tibetan name is Chomolungma or Qomolangma ,and the related Chinese name is Zhūmùlǎngmǎ Fēng or Shèngmǔ Fēng,Pinyin: Qomolangma Feng.
In 1865, the mountain was given its English name by Andrew Waugh, the British surveyor-general of India. With both Nepal and Tibet closed to foreign travel, he wrote:
I was taught by my respected chief and predecessor, Colonel Sir George Everest to assign to every geographical object its true local or native appellation. But here is a mountain, most probably the highest in the world, without any local name that we can discover, whose native appellation, if it has any, will not very likely be ascertained before we are allowed to penetrate into Nepal. In the meantime the privilege as well as the duty devolves on me to assign…a name whereby it may be known among citizens and geographers and become a household word among civilized nations.
Waugh chose to name the mountain after George Everest, first using the spelling Mont Everest, and then Mount Everest. However, the modern pronunciation of Everest (IPA: [ˈɛvərɪst] or [ˈɛvərɨst] [EV-er-est]) is in fact different from Sir George's own pronunciation of his surname, which was [ˈiv;rɪst] (EAVE-rest).
In the early 1960s, the Nepalese government realized that Mount Everest had no Nepalese name. This was because the mountain was not known and named in ethnic Nepal (that is, the Kathmandu valley and surrounding areas). The government set out to find a name for the mountain (the Sherpa/Tibetan name Chomolangma was not acceptable, as it would have been against the idea of unification (Nepalization) of the country. The name Sagarmatha (सगरमाथा) was thus invented by Baburam Acharya.
In 2002, the Chinese People's Daily newspaper published an article making a case against the continued use of the English name for the mountain in the Western world, insisting that it should be referred to by its Tibetan name. The newspaper argued that the Chinese name preceded the English one, as Mount Qomolangma was marked on a Chinese map more than 280 years ago.[4]
Measurement
Aerial view of Mount Everest.
Another aerial view of Mount Everest.Radhanath Sikdar, an Indian mathematician and surveyor from Bengal, was the first to identify Everest as the world's highest peak in 1852, using trigonometric calculations based on measurements of "Peak XV" (as it was then known) made with theodolites from 240 km (150 miles) away in India. Measurement could not be made from closer due to a lack of access to Nepal. "Peak XV" was found to be exactly 29,000 feet (8,839 m) high, but was publicly declared to be 29,002 feet (8,840 m). The arbitrary addition of 2 feet (0.6 m) was to avoid the impression that an exact height of 29,000 feet was nothing more than a rounded estimate.
More recently, the mountain has been found to be 8,848 m (29,028 feet) high, although there is some variation in the measurements. The mountain K2 comes in second at 8,611 m (28,251 feet) high. On May 22, 2005, the People's Republic of China's Everest Expedition Team ascended to the top of the mountain. After several months' complicated measurement and calculation, on October 9, 2005, the PRC's State Bureau of Surveying and Mapping officially announced the height of Everest as 8,844.43 m ± 0.21 m (29,017.16 ± 0.69 ft). They claimed it was the most accurate measurement to date.[5]. But this new height is based on the actual highest point of rock and not on the snow and ice that sits on top of that rock on the summit, so, in keeping with the practice used on Mont Blanc and Khan Tangiri Shyngy, it is not shown here. The Chinese also measured a snow/ice depth of 3.5 m,[6] which implies agreement with a net elevation of 8,848 m. But in reality the snow and ice thickness varies, making a definitive height of the snow cap, and hence the precise height attained by summiteers without sophisticated GPS, impossible to determine.
The elevation of 8,848 m (29,028 ft) was first determined by an Indian survey in 1955, made closer to the mountain, also using theodolites. It was subsequently reaffirmed by a 1975 Chinese measurement [7]. In both cases the snow cap, not the rock head, was measured. In May 1999 an American Everest Expedition, directed by Bradford Washburn, anchored a GPS unit into the highest bedrock. A rock head elevation of 8,850 m (29,035 feet), and a snow/ice elevation 1 m (3 ft) higher, were obtained via this device[8]. Although it has not been officially recognized by Nepal [9], this figure is widely quoted. Geoid uncertainty casts doubt upon the accuracy claimed by both the 1999 and 2005 surveys.
It is thought that the plate tectonics of the area are adding to the height and moving the summit north-eastwards. Two accounts, [8], [10] suggest the rates of change are 4 mm per year (upwards) 3-6 mm per year (northeastwards), but another account mentions more lateral movement (27 mm)[11], and even shrinkage has been suggested [12].
Everest is the mountain whose summit attains the greatest distance above sea level. Two other mountains are sometimes claimed as alternative "tallest mountains on Earth". Mauna Kea in Hawaii is tallest when measured from its base; it rises over 10,203 m (about 6.3 mi) when measured from its base on the mid-ocean floor, but only attains 4,205 m (13,796 ft) above sea level. The summit of Chimborazo in Ecuador is 2,168 m (7,113 ft) farther from the Earth's centre (6,384.4 km or 3,967.1 mi) than that of Everest (6,382.3 km or 3,965.8 mi), because the Earth bulges at the Equator. However, Chimborazo attains a height of 6,267 m (20,561 ft) above sea level, and by this criterion it is not even the highest peak of the Andes.
The deepest spot in the ocean is deeper than Everest is high: the Challenger Deep, located in the Mariana Trench, is so deep that if Everest were to be placed into it there would be more than 2 km (1.25 mi) of water covering it.
The Mount Everest region, and the Himalayas in general, are thought to be experiencing ice-melt due to global warming.[13] The exceptionally heavy southwest summer monsoon of 2005 is consistent with continued warming and augmented convective uplift on the Tibetan plateau to the north.[citation needed]

View from space showing South Col route and North Col/Ridge route
Southern and northern climbing routes as seen from the International Space Station.
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. Of the two main routes, the southeast ridge is technically easier and is the more frequently-used route. It was the route used by Hillary and Tenzing in 1953 and the first recognised of fifteen routes to the top by 1996. This was, however, a route decision dictated more by politics than by design as the Chinese border was closed to foreigners in 1949. Reinhold Messner (Italy) summited the mountain solo for the first time, without supplementary oxygen or support, on the more difficult Northwest route via the North Col to the North Face and the Great Couloir, on August 20th 1980. He climbed for three days entirely alone from his base camp at 6500 meters. This route has been noted as the 8th climbing route to the summit.
Most attempts are made during April and May before the summer monsoon season. A change in the jet stream at this time of year reduces the average wind speeds high on the mountain. While attempts are sometimes made after the monsoons in September and October, the additional snow deposited by the monsoons and the less stable weather patterns makes climbing more difficult.
Southeast ridge
The ascent via the southeast ridge begins with a trek to Base Camp at 5,380 m (17,600 ft) on the south side of Everest in Nepal. Expeditions usually fly into Lukla (2,860 m) from Kathmandu and pass through Namche Bazaar. Climbers then hike to Base Camp, which usually takes six to eight days, allowing for proper altitude acclimatization in order to prevent altitude sickness. Climbing equipment and supplies are carried by yaks, dzopkyos (yak hybrids) and human porters to Base Camp on the Khumbu Glacier. When Hillary and Tenzing climbed Everest in 1953, they started from Kathmandu Valley, as there were no roads further east at that time.
A view of Everest southeast ridge base camp. The Khumbu Icefall can be seen in the left. In the center are the remains of a helicopter that crashed in 2003.Climbers will spend a couple of weeks in Base Camp, acclimatizing to the altitude. During that time, Sherpas and some expedition climbers will set up ropes and ladders in the treacherous Khumbu Icefall. Seracs, crevasses and shifting blocks of ice make the icefall one of the most dangerous sections of the route. Many climbers and Sherpas have been killed in this section. To reduce the hazard, climbers will usually begin their ascent well before dawn when the freezing temperatures glue ice blocks in place. Above the icefall is Camp I or Advanced Base Camp (ABC) at 6,065 m (19,900 ft).
From Camp I, climbers make their way up the Western Cwm to the base of the Lhotse face, where Camp II is established at 6,500 m (21,300 ft). The Western Cwm is a relatively flat, gently rising glacial valley, marked by huge lateral crevasses in the centre which prevent direct access to the upper reaches of the Cwm. Climbers are forced to cross on the far right near the base of Nuptse to a small passageway known as the "Nuptse corner". The Western Cwm is also called the "Valley of Silence" as the topography of the area generally cuts off wind from the climbing route. The high altitude and a clear, windless day can make the Western Cwm unbearably hot for climbers.
From Camp II, climbers ascend the Lhotse face on fixed ropes up to Camp III, located on a small ledge at 7,470 m (24,500 ft). From there, it is another 500 metres to Camp IV on the South Col at 7,920 m (26,000 ft). From Camp III to Camp IV, climbers are faced with two additional challenges: The Geneva Spur and The Yellow Band. The Geneva Spur is an anvil shaped rib of black rock named by a 1952 Swiss expedition. Fixed ropes assist climbers in scrambling over this snow covered rock band. The Yellow Band is a section of sedimentary sandstone which also requires about 100 metres of rope for traversing it.
On the South Col, climbers enter the death zone. Climbers typically only have a maximum of two or three days they can endure at this altitude for making summit bids. Clear weather and low winds are critical factors in deciding whether to make a summit attempt. If weather does not cooperate within these short few days, climbers are forced to descend, many all the way back down to Base Camp.
From Camp IV, climbers will begin their summit push around midnight with hopes of reaching the summit (still another 1,000 metres above) within 10 to 12 hours. Climbers will first reach "The Balcony" at 8,400 m (27,700 ft), a small platform where they can rest and gaze at peaks to the south and east in the early dawn light. Continuing up the ridge, climbers are then faced with a series of imposing rock steps which usually forces them to the east into waist deep snow, a serious avalanche hazard. At 8,750 m (28,700 ft), a small table-sized dome of ice and snow marks the South Summit.
From the South Summit, climbers follow the knife-edge southeast ridge along what is known as the "Cornice traverse" where snow clings to intermittent rock. This is the most exposed section of the climb as a misstep to the left would send one 2,400 m (8,000 ft) down the southwest face while to the immediate right is the 3,050 m (10,000 ft) Kangshung face. At the end of this traverse is an imposing 12 m (40 ft) rock wall called the "Hillary Step" at 8,760 m (28,750 ft).
Hillary and Tenzing were the first climbers to ascend this step and they did it with primitive ice climbing equipment and without fixed ropes. Nowadays, climbers will ascend this step using fixed ropes previously set up by Sherpas. Once above the step, it is a comparatively easy climb to the top on moderately angled snow slopes - though the exposure on the ridge is extreme especially while traversing very large cornices of snow. After the Hillary Step, climbers also must traverse a very loose and rocky section that has a very large entanglement of fixed ropes that can be troublesome in bad weather. Climbers will typically spend less than a half-hour on "top of the world" as they realize the need to descend to Camp IV before darkness sets in, afternoon weather becomes a serious problem, or supplemental oxygen tanks run out.
Northeast ridge
Everest North FaceThe northeast ridge route begins from the north side of Everest in Tibet. Expeditions trek to the Rongbuk Glacier, setting up Base Camp at 5,180 m (17,000 ft) on a gravel plain just below the glacier. To reach Camp II, climbers ascend the medial moraine of the east Rongbuk Glacier up to the base of Changtse at around 6,100 m (20,000 ft). Camp III (ABC - Advanced Base Camp) is situated below the North Col at 6,500 m (21,300 ft). To reach Camp IV on the north col, climbers ascend the glacier to the foot of the col where fixed ropes are used to reach the North Col at 7,010 m (23,000 ft). From the North Col, climbers ascend the rocky north ridge to set up Camp V at around 7,775 m (25,500 ft). The route goes up the north face through a series of gullies and steepens into downsloping slabby terrain before reaching the site of Camp VI at 8,230 m (27,000 ft). From Camp VI, climbers will make their final summit push. Climbers must first make their way through three rock bands known as First Step: 27,890 feet - 28,00 feet, Second Step: 28,140 feet - 28,300 feet, and Third Step: 28,510 feet - 28,870 feet. Once above these steps, the final summit slopes (50 to 60 degrees) to the top.

Early expeditions
On June 8, 1924, George Mallory and Andrew Irvine, both of the United Kingdom, made an attempt on the summit via the north col/north ridge route from which they never returned.
In 1999, the Mallory and Irvine Research Expedition found Mallory's body in the predicted search area near the old Chinese camp. Controversy has raged in the mountaineering community as to whether the duo may have summited 29 years before the confirmed ascent (and of course, safe descent) of Everest by Sir Edmund Hillary and Tenzing Norgay in 1953. The general consensus among climbers has been that they did not, though recent findings may indicate otherwise.
Mallory had gone on a speaking tour of the United States the year before in 1923; it was then that he exasperatedly gave the famous reply, "Because it is there," to a New York journalist in response to hearing the question, "Why climb Everest?" for seemingly the thousandth time. Comprehensive information is available at Mallory and Irvine: The Final Chapter including critical opposing viewpoints.
In 1933, Lady Houston, a British millionaire ex-showgirl, funded the Houston Everest Flight of 1933, which saw a formation of airplanes led by the Marquess of Clydesdale fly over the summit in an effort to deploy the British Union Jack flag at the top.
Early expeditions ascended the mountain from Tibet, via the north face. However, this access was closed to western expeditions in 1950, after the Chinese reasserted control over Tibet. However, in 1950, Bill Tilman and a small party which included Charles Houston, Oscar Houston and Betsy Cowles undertook an exploratory expedition to Everest through Nepal along the route which has now become the standard approach to Everest from the south.
First successful ascent by Tenzing and Hillary
In 1953, a ninth British expedition, led by John Hunt, returned to Nepal. Hunt selected two climbing pairs to attempt to reach the summit. The first pair (Tom Bourdillon and Charles Evans) came within 300 feet of the summit on 26 May, but turned back after becoming exhausted. The next day, the expedition made its second and final assault on the summit with its second climbing pair. The summit was eventually reached at 11:30 am local time on May 29, 1953 by the New Zealander Edmund Hillary and Sherpa Tenzing Norgay from Nepal climbing the South Col Route. At the time, both acknowledged it as a team effort by the whole expedition, but Tenzing revealed a few years later that Hillary had put his foot on the summit first. They paused at the summit to take photographs and buried a few sweets and a small cross in the snow before descending. News of the expedition's success reached London on the morning of Queen Elizabeth II's coronation. Returning to Kathmandu a few days later, Hillary and Hunt discovered that they had been promptly knighted for their efforts.
1996 disaster
During the 1996 climbing season, fifteen people died trying to reach the summit, making it the deadliest single year in Everest history. The disaster gained wide publicity and raised questions about the commercialization of Everest.
Journalist Jon Krakauer, on assignment from Outside magazine, was in one of the affected parties, and afterwards published the bestseller Into Thin Air which related his experience. Anatoli Boukreev, a guide who felt impugned by Krakauer's book, co-authored a rebuttal book called The Climb. The dispute sparked a large debate within the climbing community. In May 2004, Kent Moore, a physicist, and John L. Semple, a surgeon, both researchers from the University of Toronto, told New Scientist magazine that an analysis of weather conditions on that day suggested that freak weather caused oxygen levels to plunge by around 14%[14][15].
The storm's impact on climbers on the mountain's other side, the North Ridge, where several climbers also died, was detailed in a first hand account by British filmmaker and writer Matt Dickinson in his book The Other Side of Everest.
2003 - 50th Anniversary of First Ascent
2003 marked the 50th anniversary of the first ascent, and a record number of teams, including some very distinguished climbers, climbed or attempted to climb the mountain.
2005 - Helicopter landing
On 14 May 2005, pilot Didier Delsalle of France landed a Eurocopter AS 350 B3 Helicopter on the summit of Mount Everest[16] and remained there for two minutes. (His rotors were continually engaged; this is known as a "hover landing".) His subsequent take-off set the world record for highest take-off of a rotorcraft — a record that of course cannot be beaten.[17] Delsalle had also performed a take-off two days earlier from the South Col, leading to some confusion in the press about the validity of the summit cl
