Cho Oyu (Nepali: चोयु; Tibetan : ཇོ་བོ་དབུ་ཡ; Chinese :卓奥友峰) is the sixth-highest mountain in the world at 8,188 metres (26,864 ft) above sea level. Cho Oyu means "Turquoise Goddess" in Tibetan. The mountain is the westernmost major peak of the Khumbu sub-section of the Mahalangur Himalaya 20 km west of Mount Everest. The mountain stands on the China – Nepal border.
Just a few kilometres west of Cho Oyu is Nangpa La (5,716m/18,753 ft), a glaciated pass that serves as the main trading route between the Tibetans and the Khumbu's Sherpas. This pass separates the Khumbu and Rolwaling Himalayas. Due to its proximity to this pass and the generally moderate slopes of the standard northwest ridge route, Cho Oyu is considered the easiest 8,000 metre peak to climb. It is a popular objective for professionally guided parties.
Cho Oyu's height was originally measured at 26,750 feet (8,150 m) and at the time of the first ascent it was considered the seventh highest mountain on earth, after Dhaulagiri at 8,167 metres (26,795 ft) (Manaslu, now 8,156 metres (26,759 ft), was also estimated lower at 26,658 feet (8,125 m)). A 1984 estimate of 8,201 metres (26,906 ft) made it move up to sixth place. New measurements made in 1996 by the Government of Nepal Survey Department and the Finnish Meteorological Institute in preparation for the Nepal Topographic Maps put the height at 8,188 m, one remarkably similar to the 26,867 feet (8,189 m) used by Edmund Hillary in his 1955 book High Adventure.
Cho Oyu was first attempted in 1952 by an expedition organised and financed by the Joint Himalayan Committee of Great Britain as preparation for an attempt on Mount Everest the following year. The expedition was led by Eric Shipton and included Edmund Hillary, Tom Bourdillon and George Lowe. 6,650 m (21,820 ft) and a report of Chinese troops a short distance across the border influenced Shipton to retreat from the mountain rather than continue to attempt to summit.A foray by Hillary and Lowe was stopped due to technical difficulties and avalanche danger at an ice cliff above
The mountain was first climbed on October 19, 1954, via the north-west ridge by Herbert Tichy, Joseph Jöchler and Sherpa Pasang Dawa Lama of an Austrian expedition.Cho Oyu was the fifth 8000 metre peak to be climbed, after Annapurna in June 1950, Mount Everest in May 1953, Nanga Parbat in July 1953 and K2 in July 1954. Until the ascent of Mount Everest by Reinhold Messner and Peter Habeler in 1978, this was the highest peak climbed without supplemental oxygen.
Cho Oyu is considered the easiest eight-thousander, 1⁄25th of Annapurna's). It is the second most climbed eight-thousander after Everest (whose height makes it the most popular), and has over four times the ascents of the third most popular eight-thousander, Gasherbrum II. It is marketed as a "trekking peak", achievable for climbers with high fitness, but low mountaineering experience. It has a broadly flat summit plateau with no cairn (the traditional prayer flags on Cho Oyu's summit plateau do not mark the "technical" summit), which can be a source of confusion, and debate, amongst climbers (see Elizabeth Hawley).with the lowest death-summit ratio (
Mount Everest is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The China–Nepal border runs across its summit point. Its elevation of 8,848.86 m (29,032 ft) was most recently established in 2020 by the Nepali and Chinese authorities.
Sherpa is one of the Tibetan ethnic groups native to the most mountainous regions of Nepal and the Himalayas. The term sherpa or sherwa derives from the Sherpa language words Shyar ("east") and Pa ("people"), which refer to their geographical origin of eastern Tibet.
Lhotse is the fourth highest mountain in the world at 8,516 metres (27,940 ft), after Mount Everest, K2, and Kangchenjunga. Part of the Everest massif, Lhotse is connected to the latter peak via the South Col. Lhotse means "South Peak" in Tibetan. In addition to the main summit at 8,516 metres (27,940 ft) above sea level, the mountain comprises the smaller peaks Lhotse Middle (East) at 8,414 m (27,605 ft), and Lhotse Shar at 8,383 m (27,503 ft). The summit is on the border between Tibet of China and the Khumbu region of Nepal.
Raymond Lambert was a Swiss mountaineer who together with Sherpa Tenzing Norgay reached an altitude of 8611 metres of Mount Everest, as part of a Swiss Expedition in May 1952. At the time it was the highest point that a climber had ever reached. There was a second Swiss expedition in autumn 1952, but a party including Lambert and Tenzing was forced to turn back at a slightly lower point. The following year Tenzing returned with Edmund Hillary to reach the summit on 29 May 1953.
The International Mountaineering and Climbing Federation or UIAA recognises eight-thousanders as the 14 mountains that are more than 8,000 metres (26,247 ft) in height above sea level, and are considered to be sufficiently independent from neighbouring peaks. However, there is no precise definition of the criteria used to assess independence, and, since 2012, the UIAA has been involved in a process to consider whether the list should be expanded to 20 mountains. All eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits are in the death zone.
Pumori is a mountain on the Nepal-China border in the Mahalangur section of the Himalayas. Pumori lies just eight kilometres west of Mount Everest. Pumori, meaning "the Mountain Daughter" in Sherpa language, was named by George Mallory. "Pumo" means young girl or daughter and "Ri" means mountain in Sherpa language. Climbers sometimes refer to Pumori as "Everest's Daughter". Mallory also called it Clare Peak, after his daughter.

At 6,476 metres (21,247 ft) it is classified as a trekking peak. It contains three main summits: Mera North, 6,476 metres (21,247 ft); Mera Central, 6,461 metres (21,198 ft); and Mera South, 6,065 metres (19,898 ft), as well as a smaller "trekking summit", visible as a distinct summit from the south but not marked on most maps of the region.
Apa, nicknamed "Super Sherpa", is a Nepalese Sherpa mountaineer who, until 2017, jointly with Phurba Tashi held the record for reaching the summit of Mount Everest more times than any other person. As part of The Eco Everest Expedition 2011, Apa made his 21st Mount Everest summit in May 2011 then retired after a promise to his wife to stop climbing after 22 ascents. He first summited Everest in 1990 and his last time to the summit was in 2011.
David Sharp was an English mountaineer who died near the summit of Mount Everest. His death caused controversy and debate because he was passed by a number of other climbers heading to and returning from the summit as he was dying, although a number of others tried to help him.
Dan Mazur is a climber, trekker and expedition leader who has ascended nine of the world's highest summits, including Mount Everest and K2.
