Mount Everest
Mount Everest (; Tibetan: ''Chomolungma'' ; ) 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 (snow height) of was most recently established in 2020 by the Chinese and Nepali authorities. Mount Everest attracts many climbers, including highly experienced mountaineers. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the "standard route") and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, and wind, as well as hazards from avalanches and the Khumbu Icefall. , over 300 people have died on Everest, many of whose bodies remain on the mountain. The first recorded efforts to reach Everest's summit were made by British mountaineers. As Nepal did not allow foreigner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Everest
Colonel Sir George Everest CB FRS FRAS FRGS (; 4 July 1790 – 1 December 1866) was a British surveyor and geographer who served as Surveyor General of India from 1830 to 1843. After receiving a military education in Marlow, Everest joined the East India Company and arrived in India at the age of 16. He was eventually made an assistant to William Lambton on the Great Trigonometric Survey, and replaced Lambton as superintendent of the survey in 1823. Everest was largely responsible for surveying the meridian arc from the southernmost point of India north to Nepal, a distance of about , a task that took from 1806 to 1841 to complete. He was made Surveyor General of India in 1830, retiring in 1843 and returning to England. In 1865, the Royal Geographical Society renamed Peak XV – at the time only recently identified as the world's highest peak – to Mount Everest in his honour. Andrew Scott Waugh, his protégé and successor as surveyor general, had been responsible for put ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Col
The South Col is a sharp-edged col between Mount Everest and Lhotse, the highest and fourth-highest mountains in the world, respectively. The South Col is typically swept by high winds, leaving it free of significant snow accumulation. Since 1950 (when Tibet was closed), most Everest expeditions have left from Nepal and gone via the southeast ridge and the South Col (instead of via the North Col). When climbers attempt to climb Everest from the southeast ridge in Nepal, their final camp (usually Camp IV) is situated on the South Col. The South Col was first reached on 12 May 1952 by Aubert, Lambert, and Flory of Edouard Wyss-Dunant's Swiss Mount Everest Expedition that failed to reach the summit. The following year, when Mount Everest was first climbed, Wilfrid Noyce and the Sherpa Annullu were the first climbers on the expedition to reach the col. According to John Hunt, the expedition leader: Once on the South Col, climbers have entered the death zone; altitude sickne ...

Mountaineering
Mountaineering or alpinism, is a set of outdoor activities that involves ascending tall mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing. The consequences of mountaineering on the natural environment can be seen in terms of individual components of the environment (land relief, soil, vegetation, fauna, and landscape) and locat ...

List Of People Who Died Climbing Mount Everest
At least 310 people have died attempting to reach the summit of Mount Everest which, at , is Earth's highest mountain and a particularly desirable peak for mountaineers. The most recent years without known deaths on the mountain are 1977, in which only two people reached the summit, and 2020, when permits were suspended by Nepal because of the COVID-19 pandemic in Nepal. Deaths have been attributed to avalanches, falls, serac collapse, exposure, frostbite, or health problems related to conditions on the mountain. Not all bodies have been located, so details on those deaths are not available. The upper reaches of the mountain are in the death zone, a mountaineering term for altitudes above a certain point – around , or less than of atmospheric pressure – where the oxygen pressure level is not sufficient to sustain human life. Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly (loss of vital functions) or indirectly ...

Khumbu Icefall
The Khumbu Icefall is located at the head of the Khumbu Glacier and the foot of the Western Cwm, which lies at an elevation of on the Nepali slopes of Mount Everest, not far above Base Camp and southwest of the summit. The icefall is considered one of the most dangerous stages of the South Col route to Everest's summit. Overview The Khumbu Glacier moves an estimated down the flank of Mt. Everest every day. Ice entering the fall takes approximately 4.3 years to emerge at the base which is 2,000 vertical feet lower and one linear mile away. The speed of ice flow and the precipitous elevation drop, creates a bergschrund (ice berg shoulder) characterized at the top by massive transverse blocks that calve off the upper glacier creating gaping crevasses (hundreds of feet deep and often over 50 feet wide). As these massive initial glacial segments descend the fall, they are slowly twisted and crushed by the churning pressure of glacial flow, generating increasingly torturous crevass ...

Avalanche
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be set off spontaneously, by such factors as increased precipitation or snowpack weakening, or by external means such as humans, animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, mudslides, rock slides, and serac collapses. They are also different from large scale movem ...

Altitude Sickness
Altitude sickness, the mildest form being acute mountain sickness (AMS), is the harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. People can respond to high altitude in different ways. Symptoms may include headaches, vomiting, tiredness, confusion, trouble sleeping, and dizziness. Acute mountain sickness can progress to high-altitude pulmonary edema (HAPE) with associated shortness of breath or high-altitude cerebral edema (HACE) with associated confusion. Chronic mountain sickness may occur after long-term exposure to high altitude. Altitude sickness typically occurs only above , though some are affected at lower altitudes. Risk factors include a prior episode of altitude sickness, a high degree of activity, and a rapid increase in elevation. Diagnosis is based on symptoms and is supported in those who have more than a minor reduction in activities. It is recommended that at high altitude any symptoms of headache, nausea ...

National Geographic
''National Geographic'' (formerly the ''National Geographic Magazine'', sometimes branded as NAT GEO) is a popular American monthly magazine published by National Geographic Partners. Known for its photojournalism, it is one of the most widely read magazines of all time. The magazine was founded in 1888 as a scholarly journal, nine months after the establishment of the society, but is now a popular magazine. In 1905, it began including pictures, a style for which it became well-known. Its first color photos appeared in the 1910s. During the Cold War, the magazine committed itself to present a balanced view of the physical and human geography of countries beyond the Iron Curtain. Later, the magazine became outspoken on environmental issues. Since 2019, controlling interest has been held by The Walt Disney Company. Topics of features generally concern geography, history, nature, science, and world culture. The magazine is well known for its distinctive appearance: a thick s ...

Summit
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

China–Nepal Border
The China–Nepal border is the international boundary between the Tibet Autonomous Region of China and Nepal. It is in length and runs in a northwest–southeast direction along the Himalayan mountain range, including Mount Everest, the world's highest mountain. The boundaries of this particular border have changed dramatically over time, especially when considering relatively recent events such as the Annexation of Tibet in 1949. However, some of the most significant developments of modern times would be the signing of the "''Agreement on Maintaining Friendly Relations between the People’s Republic of China and the Kingdom of Nepal''" in 1956 and the " Sino-Nepalese Treaty of Peace and Friendship" in 1960, both of which formally recognised Tibet as a part of China and confirmed the limits of the countries of China and Nepal as they are known today. Description The border starts in the west at the western tripoint with India near the Tinkar Pass in Sudurpashchim Province ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, mountain glaciers and the polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlement and ...

Tibetic Languages
The Tibetic languages form a well-defined group of languages descended from Old Tibetan (7th to 9th centuries).Tournadre, Nicolas. 2014. "The Tibetic languages and their classification." In ''Trans-Himalayan linguistics, historical and descriptive linguistics of the Himalayan area''. Berlin: Mouton de Gruyter. According to Tournadre (2014), there are 50 languages, which split into over 200 dialects or could be group into 8 dialect continua. These languages are spoken in the Tibetan Plateau and in the Himalayas in Gilgit-Baltistan, Aksai Chin, Ladakh, Nepal, Himachal Pradesh, Uttarakhand, and Bhutan. Classical Tibetan is the major literary language, particularly for its use in Buddhist literature. Tibetan languages are spoken by some 6 million people, not all of whom are Tibetans. With the worldwide spread of Tibetan Buddhism, the Tibetan language has spread into the western world and can be found in many Buddhist publications and prayer materials; with some western st ...
