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 was most recently established in 2020 by the Chinese and Nepali authorities.
Cho Oyu 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 Tibet–Nepal Province No. 1 border.
George Herbert Leigh-Mallory was an English mountaineer who participated in the first three British Mount Everest expeditions from the early to mid-1920s.
Andrew Comyn "Sandy" Irvine was an English mountaineer who took part in the 1924 British Everest Expedition, the third British expedition to the world's highest mountain, Mount Everest.
The goal of the Mallory and Irvine Research Expedition of 1999 was to discover evidence of whether George Mallory and Andrew Irvine had been the first to summit Mount Everest in their attempt of 8–9 June 1924. The expedition was instigated by British climber Graham Hoyland. It was organised by regular Everest expedition leader Eric Simonson and advised by researcher Jochen Hemmleb, with a team of climbers from the United States, the United Kingdom, and Germany. Hemmleb's investigations of reports of earlier sightings and photographs had led him to identify what he believed was the area in which Irvine's body lay, some distance below where his ice axe had been found by Percy Wyn-Harris on the expedition led by Hugh Ruttledge in 1933. The team hoped in particular to find a camera on Irvine's body which, had the pair been successful, should have contained a picture of the summit. After commencing the search on 1 May 1999, Conrad Anker mistakenly got off course and, surprisingly, found Mallory's body, not Irvine's.
Noel Ewart Odell FRSE FGS was an English geologist and mountaineer. In 1924 he was an oxygen officer on the Everest expedition in which George Mallory and Andrew Irvine famously perished during their summit attempt. Odell spent two weeks living above 23,000 feet (7,000 m), and twice climbed to 26,800 feet (8,200 m) and higher, all without supplemental oxygen. In 1936 Noel Odell with Bill Tilman climbed Nanda Devi, at the time the highest mountain climbed.
Stephen Venables is a British mountaineer and writer, and is a past president of the South Georgia Association and of the Alpine Club. He is the first Briton to ascend the summit of Mount Everest without bottled oxygen.
The Kangshung Face or East Face is the eastern-facing side of Mount Everest, one of the Tibetan sides of the mountain. It is 3,350 metres (11,000 ft) from its base on the Kangshung Glacier to the summit. It is a broad face, topped on the right by the upper Northeast Ridge, and on the left by the Southeast Ridge and the South Col. Most of the upper part of the face is composed of hanging glaciers, while the lower part consists of steep rock buttresses with couloirs between them. The steep southern third of the Kangshung Face also comprises the Northeastern Face of Lhotse; this section may be considered a separate face altogether following the division of the South "Neverest" Buttress up to the South Col. It is considered to be a dangerous route of ascent, compared to the standard North Col and South Col routes, and it is the most remote face of the mountain, with a longer approach.
Mount Everest is the world's highest mountain, with a peak at 8,849 metres (29,031.7 ft) above sea level. It is situated in the Himalayan range of Solukhumbu district, Nepal.
Michael Horatio Westmacott was a prominent British mountaineer.
Sir Robert Charles Evans was a British mountaineer, surgeon, and educator. He was leader of the 1955 British Kangchenjunga expedition and deputy leader of the 1953 British Mount Everest expedition, both of which were successful.
Thomas Duncan Bourdillon was an English mountaineer and member of the 1953 British Mount Everest Expedition which made the first ascent of Mount Everest. He died in Valais, Switzerland, on 29 July 1956 aged 32.
The Mount Everest Committee was a body formed by the Alpine Club and the Royal Geographical Society to co-ordinate and finance the 1921 British Mount Everest reconnaissance expedition to Mount Everest and all subsequent British expeditions to climb the mountain until 1947. It was then renamed the Joint Himalayan Committee; this latter committee organised and financed the successful first ascent of Mount Everest in 1953.
David Allen Hahn is an American professional mountain guide, ski patroller, journalist and lecturer. In May 2013, he reached the summit of Mount Everest for the 15th time—at the time, this was the most summits for a non-Sherpa climber, according to Outside Magazine contributor and climber Alan Arnette. His record was surpassed by Kenton Cool in 2022. Among Hahn’s other notable accomplishments are his 39 summits of Vinson Massif, Antarctica’s highest mountain. He has reached the summit of Denali in Alaska, North America’s highest peak, 25 times over the course of 37 expeditions.
The 1924 British Mount Everest expedition was—after the 1922 British Mount Everest expedition—the 2nd expedition with the goal of achieving the first ascent of Mount Everest. After two summit attempts in which Edward Norton set a world altitude record of 8,572.8 metres (28,126 ft), the mountaineers George Mallory and Andrew "Sandy" Irvine disappeared on the third attempt. Their disappearance has given rise to the long-standing speculation of whether or not the pair might – under a narrow set of assumptions – have reached the summit. Mallory's body was found in 1999 at 8,156 metres (26,760 ft), but the resulting clues did not provide any conclusive evidence as to whether the summit was reached.
The 1953 British Mount Everest expedition was the ninth mountaineering expedition to attempt the first ascent of Mount Everest, and the first confirmed to have succeeded when Tenzing Norgay and Edmund Hillary reached the summit on 29 May 1953. Led by Colonel John Hunt, it was organised and financed by the Joint Himalayan Committee. News of the expedition's success reached London in time to be released on the morning of Queen Elizabeth II's coronation, on 2 June that year.
Major General John Geoffrey Bruce was an officer in the British Indian Army, eventually becoming Deputy Chief of General Staff, who participated in the 1922 British Mount Everest expedition. Bruce, who had never before climbed a mountain, had been appointed as a transport officer, but chance led to him accompanying George Finch on the only summit attempt that used supplemental oxygen. Together they set a new mountaineering world record height of 27,300 ft (8,321 m), only 1,731.7 ft (527.82 m) below the summit of Mount Everest.
The South Summit is a subsidiary peak to the primary peak of Mount Everest in the Himalayas. Although the South Summit's elevation above sea level of 8,749 metres (28,704 ft) is higher than the second-highest mountain on Earth, K2, it is not considered a separate mountain as its prominence is only 11 meters. The primary peak of Mount Everest is 8,849 metres (29,032 ft) elevation above sea level.
Norman David Hardie was a New Zealand climber who was one of the climbers on the 1955 British Kangchenjunga expedition who first reached the summit of the 8,586-metre (28,169 ft) mountain, the third-highest mountain in the world.
The 1952 British expedition to Cho Oyu the Turquoise Goddess was organized by the Joint Himalayan Committee. It had been hoped to follow up the 1951 Everest expedition with another British attempt on Everest in 1952, but Nepal had accepted a Swiss application for 1952, to be followed in 1953 with a British attempt. So in 1952, Eric Shipton was to lead an attempt to ascend Cho Oyu, and Griffith Pugh was to trial oxygen equipment and train members for 1953. But the expedition failed both aims; that plus Shipton’s poor leadership and planning resulted in his replacement as a leader for the 1953 expedition.
