Interest

Mount Everest (Nepali: सगरमाथा, Sagarmāthā; Tibetan: ཇོ་མོ་གླང་མ, Wylie: jo mo glang ma; Chomolungma orQomolangma /ˈtʃoʊmoʊˌlɑːŋmə/ "Holy Mother"; Chinese: 珠穆朗玛峰; pinyin: Zhūmùlǎngmǎ Fēng;) is the Earth'shighest mountain, with a peak at 8,848 metres (29,029 ft) above sea level and the 5th tallest mountain measured from the centre of the Earth. It is located in the Mahalangur section of the Himalayas. The international border between China and Nepal runs across the precise summit point. Its massif includes neighboring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft) and Changtse, 7,580 m (24,870 ft).

In 1856, the Great Trigonometric Survey of British India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. Waugh named the mountain after his predecessor in the post, Sir George Everest. Although Tibetans had called Everest "Chomolungma" for centuries, Waugh was unaware of this because Nepal and Tibet were closed to foreigners.

Mount Everest attracts many highly experienced mountaineers as well as capable climbers willing to hire professional guides. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather and wind.

Published by the Survey of Nepal, this is Map 50 of the 57 map set at 1:50,000 scale "attached to the main text on the First Joint Inspection Survey, 1979–80, Nepal-China border." In the top center, note the boundary line, identified as separating "China" and "Nepal", passing exactly through the summit contour. The boundary here and for much of the China-Nepal border follows the main Himalayan watershed divide.

In 1802, the British began the Great Trigonometric Survey of India to determine the location and names of the world's highest mountains. Starting in southern India, the survey teams moved northward using gianttheodolites, each weighing 500 kg (1,100 lb) and requiring 12 men to carry, to measure heig
