world second highest mountain K2 Tribute pakistan

K2 is the second-highest mountain on Earth after Mount Everest. With a peak elevation of 8,611 metres (28,251 ft), K2 is part of the Karakoram Range, and is located on the border[2] between the Taxkorgan Tajik Autonomous County of Xinjiang, China, and Gilgit, in Gilgit-Baltistan of Pakistan.[3][note]
K2 is known as the Savage Mountain due to the difficulty of ascent and the 2nd highest fatality rate among the "eight thousanders" for those who climb it. For every four people who have reached the summit, one has died trying.[4] Unlike Annapurna, the mountain with the highest fatality rate, K2 has never been climbed in winter.
The name K2 is derived from the notation used by the Great Trigonometric Survey. Thomas Montgomerie made the first survey of the Karakoram from Mount Haramukh, some 130 miles (210 km) to the south, and sketched the two most prominent peaks, labelling them K1 and K2.[5]
The policy of the Great Trigonometric Survey was to use local names for mountains wherever possible[6] and K1 was found to be known locally as Masherbrum. K2, however, appeared not to have acquired a local name, possibly due to its remoteness. The mountain is not visible from Askole, the last village to the south, or from the nearest habitation to the north, and is only fleetingly glimpsed from the end of the Baltoro Glacier, beyond which few local people would have ventured.[7] The name Chogori, derived from two Balti words, chhogo ('big') and ri ('mountain') (شاہگوری) has been suggested as a local name, but evidence for its widespread use is scant. It may have been a compound name invented by Western explorers[8] or simply a bemused reply to the question "What's that called?"[7] It does, however, form the basis for the name Qogir (simplified Chinese: 乔戈里峰; traditional Chinese: 喬戈里峰; pinyin: Qiáogēlǐ Fēng) by which Chinese authorities officially refer to the peak. Other local names have been suggested including Lamba Pahar ("Tall Mountain" in Urdu) and Dapsang, but are not widely used.[7]
Lacking a local name, the name Mount Godwin-Austen was suggested, in honour of Henry Godwin-Austen, an early explorer of the area, and while the name was rejected by the Royal Geographical Society[7] it was used on several maps, and continues to be used occasionally.[9][10]
The surveyor's mark, K2, therefore continues to be the name by which the mountain is commonly known. It is now also used in the Balti language, rendered as Kechu or Ketu[8][11] (Urdu: کے ٹو). The Italian climber Fosco Maraini argued in his account of the ascent of Gasherbrum IV that while the name of K2 owes its origin to chance, its clipped, impersonal nature is highly appropriate for so remote and challenging a mountain. He concluded that it was...[12]
...just the bare bones of a name, all rock and ice and storm and abyss. It makes no attempt to sound human. It is atoms and stars. It has the nakedness of the world before the first man – or of the cindered planet after the last.

[edit] Geographical setting

K2 lies in the northwestern Karakoram Range. The Tarim sedimentary basin borders the range on the north and the Lesser Himalayas on the south. Melt waters from vast glaciers, such as those south and east of K2, feed agriculture in the valleys and contribute significantly to the regional fresh-water supply. The Karakoram Range lies along the southern edge of the Eurasian tectonic plate and is made up of ancient sedimentary rocks (more than 390 million years old). Those strata were folded and thrust-faulted, and granite masses were intruded, when the Indian plate collided with Eurasia, beginning more than 100 million years ago.[13]
K2 is only ranked 22nd by topographic prominence, a measure of a mountain's independent stature, because it is part of the same extended area of uplift (including the Karakoram, the Tibetan Plateau, and the Himalaya) as Mount Everest, in that it is possible to follow a path from K2 to Everest that goes no lower than 4,594 m (15,072 ft) (at Mustang Lo). Many other peaks which are far lower than K2 are more independent in this sense.
However, K2 is notable for its local relief as well as its total height. It stands over 3,000 metres (9,843 ft) above much of the glacial valley bottoms at its base. More extraordinary is the fact that it is a consistently steep pyramid, dropping quickly in almost all directions. The north side is the steepest: there it rises over 3,200 metres (10,499 ft) above the K2 (Qogir) Glacier in only 3,000 metres (9,843 ft) of horizontal distance. In most directions, it achieves over 2,800 metres (9,186 ft) of vertical relief in less than 4,000 metres (13,123 ft).[14]

[edit] Climbing history

[edit] Early attempts

The mountain was first surveyed by a European survey team in 1856. Thomas Montgomerie was the member of the team who designated it "K2" for being the second peak of the Karakoram range. The other peaks were originally named K1, K3, K4 and K5, but were eventually renamed Masherbrum, Broad Peak, Gasherbrum II and Gasherbrum I respectively. In 1892, Martin Conway led a British expedition that reached 'Concordia' on the Baltoro Glacier.[15]
The first serious attempt to climb K2 was undertaken in 1902 by Oscar Eckenstein and Aleister Crowley, via the Northeast Ridge. In the early 1900s, modern transportation did not exist: It took "fourteen days just to reach the foot of the mountain".[16] After five serious and costly attempts, the team reached 6,525 metres (21,407 ft)[17] – although considering the difficulty of the challenge, and the lack of modern climbing equipment or weatherproof fabrics, Crowley's statement that "neither man nor beast was injured" highlights the pioneering spirit and bravery of the attempt. The failures were also attributed to sickness (Crowley was suffering the residual effects of malaria), a combination of questionable physical training, personality conflicts, and poor weather conditions — of 68 days spent on K2 (at the time, the record for the longest time spent at such an altitude) only eight provided clear weather.[18]
The next expedition to K2 in 1909, led by Luigi Amedeo, Duke of the Abruzzi, reached an elevation of around 6,250 metres (20,505 ft) on the South East Spur, now known as the Abruzzi Spur (or Abruzzi Ridge). This would eventually become part of the standard route, but was abandoned at the time due to its steepness and difficulty. After trying and failing to find a feasible alternative route on the West Ridge or the North East Ridge, the Duke declared that K2 would never be climbed, and the team switched its attention to Chogolisa, where the Duke came within 150 metres (492 ft) of the summit before being driven back by a storm.[19]

The next attempt on K2 was not made until 1938, when an American expedition led by Charles Houston made a reconnaissance of the mountain. They concluded that the Abruzzi Spur was the most practical route, and reached a height of around 8,000 metres (26,247 ft) before turning back due to diminishing supplies and the threat of bad weather.[20][21] The following year an expedition led by Fritz Wiessner came within 200 metres (656 ft) of the summit, but ended in disaster when Dudley Wolfe, Pasang Kikuli, Pasang Kitar and Pintso disappeared high on the mountain.[22][23]
Charles Houston returned to K2 to lead the 1953 American expedition. The expedition failed due to a storm which pinned the team down for ten days at 7,800 metres (25,591 ft), during which time Art Gilkey became critically ill. A desperate retreat followed, during which Pete Schoening saved almost the entire team during a mass fall, and Gilkey was killed, either in an avalanche or in a deliberate attempt to avoid burdening his companions. In spite of the failure and tragedy, the courage shown by the team has given the expedition iconic status in mountaineering history.[24][25][26]

[edit] Success and repeats

An Italian expedition finally succeeded in ascending to the summit of K2 via the Abruzzi Spur on July 31, 1954. The expedition was led by Ardito Desio, although the two climbers who actually reached the top were Lino Lacedelli and Achille Compagnoni. The team included a Pakistani member, Colonel Muhammad Ata-ullah, who had been a part of the 1953 American expedition. Also on the expedition were the famous Italian climber Walter Bonatti and Pakistani Hunza porter Mahdi, who proved vital to the expedition's success in that they carried oxygen to 26,600 feet (8,100 m) for Lacedelli and Compagnoni. Their dramatic bivouac in the open at that altitude wrote another chapter in the saga of Himalayan climbing.
On August 9, 1977, 23 years after the Italian expedition, Ichiro Yoshizawa led the second successful ascent to the top; with Ashraf Aman as the first native Pakistani climber. The Japanese expedition ascended through the Abruzzi Spur route traced by the Italians, and used more than 1,500 porters to achieve the goal.
The West Face and upper slopes of K2
The year 1978 saw the third ascent of K2, via a new route, the long, corniced Northeast Ridge. (The top of the route traversed left across the East Face to avoid a vertical headwall and joined the uppermost part of the Abruzzi route.) This ascent was made by an American team, led by noted mountaineer James Whittaker; the summit party were Louis Reichardt, Jim Wickwire, John Roskelley, and Rick Ridgeway. Wickwire endured an overnight bivouac about 150 metres (492 ft) below the summit, one of the highest bivouacs in climbing history. This ascent was emotional for the American team, as they saw themselves as completing a task that had been begun by the 1938 team forty years earlier.[27]
Another notable Japanese ascent was that of the difficult North Ridge, on the Chinese side of the peak, in 1982. A team from the Mountaineering Association of Japan led by Isao Shinkai and Masatsugo Konishi put three members, Naoe Sakashita, Hiroshi Yoshino, and Yukihiro Yanagisawa, on the summit on August 14. However Yanagisawa fell and died on the descent. Four other members of the team achieved the summit the next day.[28]
The first climber to summit K2 twice was Czech climber Josef Rakoncaj. Rakoncaj was a member of the 1983 Italian expedition led by Francesco Santon, which made the second successful ascent of the North Ridge (July 31, 1983). Three years later, on July 5, 1986, he summitted on the Abruzzi Spur (double with Broad Peak West Face solo) as a member of Agostino da Polenza's international expedition.

[edit] Recent attempts

The peak has now been climbed by almost all of its ridges. Although the summit of Everest is at a higher altitude, K2 is a much more difficult and dangerous climb, due in part to its more inclement weather and comparatively greater height from base to peak. The mountain is believed by many[who?] to be the world's most difficult and dangerous climb, hence its nickname "the Savage Mountain." It, and the surrounding peaks, have claimed more lives than any others.[29] As of July 2010, only 302 people have completed the ascent,[30] compared with over 2,700 individuals who have ascended the more popular target of Everest. At least 77 people have died attempting the climb. Notably, 13 climbers from several expeditions died in 1986 in the 1986 K2 Disaster, five of these in a severe storm. More recently, on August 1, 2008, a group of climbers went missing after a large piece of ice fell during an avalanche taking out the fixed ropes on part of the route; four climbers were rescued, but 11, including Gerard McDonnell, the first Irish person to reach the summit, were confirmed dead.[31] On 6 August 2010, Fredrik Ericsson, who intended to ski from the summit, joined Gerlinde Kaltenbrunner on the way to the summit of K2. Ericsson fell 1,000 metres (3,300 ft) and was killed. Kaltenbrunner aborted her summit attempt.[32]

[edit] Climbing routes and difficulties

A scale comparison of the Matterhorn and K2 gives an impression of the massive size of K2.
There are a number of routes on K2, of somewhat different character, but they all share some key difficulties. First, of course, is the extreme high altitude and resulting lack of oxygen: there is only one-third as much oxygen available to a climber on the summit of K2 as there is at sea level.[33] Second is the propensity of the mountain to experience extreme storms of several days' duration, which have resulted in many of the deaths on the peak. Third is the steep, exposed, and committing nature of all routes on the mountain, which makes retreat more difficult, especially during a storm. Despite many attempts there have been no successful winter ascents. All major climbing routes lie on the Pakistani side, which is also where the base camp is located.

[edit] Abruzzi Spur

Climbing ladders on Abruzzi Spur
The standard route of ascent, used far more than any other route, is the Abruzzi Spur,[34][35] located on the Pakistani side, first attempted by Luigi Amedeo, Duke of the Abruzzi in 1909. This is the southeast ridge of the peak, rising above the Godwin Austen Glacier. The spur proper begins at an altitude of 5,400 m/17,700 ft, where Advanced Base Camp is usually placed. The route follows an alternating series of rock ribs, snow/ice fields, and some technical rock climbing on two famous features, "House's Chimney" and the "Black Pyramid." Above the Black Pyramid, dangerously exposed and difficult to navigate slopes lead to the easily visible "Shoulder", and thence to the summit. The last major obstacle is a narrow couloir known as the "Bottleneck", which places climbers dangerously close to a wall of seracs which form an ice cliff to the east of the summit. It was partly due to the collapse of one of these seracs around 2001 that no climbers summitted the peak in 2002 and 2003.[36]
On August 1, 2008, a number of climbers went missing when a serac in the Bottleneck snapped and broke their ropes.[37][38] Survivors were seen from a helicopter but rescue efforts were impeded by the high altitude. Eleven were never found, and presumed dead.[31]

[edit] North Ridge

The north side of K2. The North Ridge is in the centre of the picture.
Almost opposite from the Abruzzi Spur is the North Ridge,[34][35] which ascends the Chinese side of the peak. It is rarely climbed, partly due to very difficult access, involving crossing the Shaksgam River, which is a hazardous undertaking.[39] In contrast to the crowds of climbers and trekkers at the Abruzzi basecamp, usually at most two teams are encamped below the North Ridge. This route, more technically difficult than the Abruzzi, ascends a long, steep, primarily rock ridge to high on the mountain (Camp IV, the "Eagle's Nest", 7,900 m/25,900 ft), and then crosses a dangerously slide-prone hanging glacier by a leftward climbing traverse, to reach a snow couloir which accesses the summit.
Besides the original Japanese ascent, a notable ascent of the North Ridge was the one in 1990 by Greg Child, Greg Mortimer, and Steve Swenson, which was done alpine style above Camp 2, though using some fixed ropes already put in place by a Japanese team.[39]

[edit] Other routes

The major routes to have been climbed on the south side of the mountain. A:West Ridge B:West Face C:Southwest Pillar D:South Face E:South-southeast Spur F: Abruzzi Spur
  • Northeast Ridge (long and corniced; finishes on uppermost part of Abruzzi route), 1978.
  • West Ridge, 1981.
  • Southwest Pillar or "Magic Line", very technical, and second most demanding. First climbed in 1986 by the Polish-Slovak trio Piasecki-Wróż-Božik. Since then the Catalan Jordi Corominas was the only successful climber on this route, despite many other attempts.
  • South Face or "Polish Line" (extremely exposed and most dangerous). In 1986, Jerzy Kukuczka and Tadeusz Piotrowski summitted on this route. Reinhold Messner called it a suicidal route and no one has repeated their achievement. "The route is so avalanche-prone, that no one else has ever considered a new attempt."[40]
  • Northwest Face, 1990.
  • Northwest Ridge (finishing on North Ridge). First ascent in 1991.
  • South-southeast spur or "Cesen route" (finishing on Abruzzi route. A possibly safer alternative to the Abruzzi Spur because of avoiding the first big obstacle on Abruzzi called Black Pyramid ), 1994.

[edit] Bottled oxygen

For most of its climbing history, K2 was not usually climbed with bottled oxygen, and small, relatively lightweight teams were the norm.[34][35] However the 2004 season saw a great increase in the use of oxygen: 28 of 47 summiteers used oxygen in that year.[36]
Acclimatisation is essential when climbing without oxygen to avoid some degree of altitude sickness.[41] K2's summit is well above the altitude at which high altitude pulmonary edema (HAPE), or high altitude cerebral edema (HACE) can occur,[42] above the 8000-metre altitude that marks the boundary of the "death zone."
