Gasherbrum II

Gasherbrum II surveyed as K4, is the 13th highest mountain in the world at 8,035 metres (26,362 ft) above sea level. It is the third-highest peak of the Gasherbrum massif, and is located in the Karakoram, on the border between Gilgit–Baltistan province, Pakistan, and Xinjiang, China. The mountain was first climbed on July 7, 1956, by an Austrian expedition which included Fritz Moravec, Josef Larch, and Hans Willenpart.

Gasherbrum II is located on the border of Gilgit–Baltistan, Pakistan, and Xinjiang, China. It is part of the Karakoram mountain range in the Himalayas, and located at the top of the Baltoro Glacier. With an elevation of 8,035 metres (26,362 ft) it is the third-highest member of the Gasherbrum group, behind Gasherbrum I (8,080 metres or 26,510 feet) and Broad Peak (8,051 metres or 26,414 feet). Gasherbrum III is sometimes considered to be a subpeak of Gasherbrum II, because the former has a topographic prominence of only 461 metres (1,512 ft).

In 1856, Thomas George Montgomerie, a member of the British Royal Engineers and part of the Great Trigonometric Survey, sighted the mountain and named it "K4", meaning the fourth mountain of Karakoram. The name "Gasherbrum" comes from the Balti words rgasha ("beautiful") and brum ("mountain"); it does not, contrary to popular belief, mean "shining wall", how Sir William Martin Conway described nearby Gasherbrum IV on an 1892 exploration.

The mountains of the Gasherbrum group were explored in 1909 by the Duke of the Abruzzi and Vittorio Sella. The Abruzzi Glacier, a tributary of the Baltoro Glacier, is named after the Duke.

In 1934, Günter Dyhrenfurth and his International Himalayan Expedition, including André Roch, explored Gasherbrum I and II, making it 6,250 metres (20,510 ft) up Gasherbrum II.

The first ascent came on July 7, 1956, by Austrians Fritz Moravec, Josef Larch and Hans Willenpart by the Southwest Ridge. After they set up Camp I, they had to descend, and found the camp—and all their supplies and food—buried by an avalanche when they returned. Despite this, they decided to make a quick summit attempt. After opening up a route, they left Camp III on July 6. The group spent the night in a bivouac sack and reached the top at 11:30 am the next day.

In 1975, four expeditions successfully climbed Gasherbrum II, including Jean-Pierre Fresafond's French expedition, a Polish group under Janusz Onyszkiewicz, and another Polish expedition led by Wanda Rutkiewicz.

Four years later, a Chilean group claimed to have used the "normal" route to reach the top. Several others, including Reinhard Karl, Hanns Schell, and Kurt Diemberger also reached the summit.

On July 24, 1982, Reinhold Messner, along with Nazir Sabir and Sher Khan, climbed the peak via the Southwest Ridge. During that year, Messner also climbed two other eight-thousanders, Kangchenjunga and Broad Peak, and attempted Cho Oyu. He wrote a book, 3 x 8000: My Great Year in the Himalaya (German: 3 x 8000: Mein grosses Himalaja-Jahr), about this.

In July 1984, Reinhold Messner and Hans Kammerlander reached both Gasherbrum II and Hidden Peak without returning to base camp, in alpine style.

In August 1984, a French expedition led by Daniel Croisot, CAF Besançon, reached summit and achieved the integral 1st descent by ski of Gasherbrum 2, as witnessed and joined by Dr Dominique Dock who was medical officer for the expedition.

In August 1986, Gasherbrum II was successfully ascended by a Slovene expedition in only 32 hours from the base to the peak, with only 22 hours of climbing and 10 hours of rest at the altitude of 5900 m. This was by far the fastest ascent until then.

In July 1996, Jean-Christophe Lafaille climbed Gasherbrum I and II in four days, without stopping at Base Camp in between.

In 2006, Sebastian Haag and Benedikt Böhm climbed Gasherbrum II twice within a week. At 8:00 am on July 29, they reached the top and then skied down without abseiling or removing their skis. They rested for a few days before leaving Base 1 again on August 3. They started out fast, reaching Camp IV in six hours, but 50 centimetres (20 in) of fresh snow slowed them down, and they reached the summit after over six hours of tough climbing. They descended on skis again, this time made even more dangerous by packed-down snow and the risk of avalanche. Despite this, they both made it safely back to Camp I in under 17 hours, whereas a normal expedition takes four to seven days.

Karl Unterkircher and Daniele Bernasconi, two Italians, climbed Gasherbrum II in 2007 in alpine style. They were the first to use the North Face through China. The route had been attempted a year earlier by a German–Swiss team, but they abandoned it after an avalanche. During the attempt they fixed around 1,200 metres (3,900 ft) of rope. They arrived at the summit around 8:00 pm on July 20, after spending the night in a bivouac shelter. A third member, Michele Compagnoni, grandson of Achille Compagnoni, turned back just 150 metres (490 ft) before the summit. The team reunited and descended down the normal, northwest route.

On February 2, 2011, Cory Richards, Denis Urubko, and Simone Moro became the first to ascend Gasherbrum II in winter. Despite being buried by a class-four avalanche, they reached the summit at 11:30 am, without supplemental oxygen or porters. Richards, who was the first American to climb an eight-thousander in winter, filmed the expedition, which he turned into the film Cold.
