Topographic prominence
In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the parent peak is some higher mountain, selected according to various criteria.
Terrain cartography
Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed. Terrain or relief is an essential aspect of physical geography, and as such its portrayal presents a central problem in cartographic design, and more recently geographic information systems and geovisualization. The most ancient form of relief depiction in cartography, hill profiles are simply illustrations of mountains and hills in profile, placed as appropriate on generally small-scale (broad area of coverage) maps.
High-altitude cerebral edema
High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude. It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms. It occurs when the body fails to acclimatize while ascending to a high altitude. It appears to be a vasogenic edema (fluid penetration of the blood–brain barrier), although cytotoxic edema (cellular retention of fluids) may play a role as well.
Retreat of glaciers since 1850
The retreat of glaciers since 1850 is well documented and is one of the effects of climate change. The retreat of mountain glaciers, notably in western North America, Asia, the Alps and tropical and subtropical regions of South America, Africa and Indonesia, provide evidence for the rise in global temperatures since the late 19th century. The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level, which would affect coastal regions.
Kangchenjunga
Kangchenjunga, also spelled Kanchenjunga, Kanchanjanghā and Khangchendzonga, is the third-highest mountain in the world. Its summit lies at in a section of the Himalayas, the Kangchenjunga Himal, which is bounded in the west by the Tamur River, in the north by the Lhonak River and Jongsang La, and in the east by the Teesta River. It lies in the border region between Nepal and Mangan district, Sikkim state of India, with three of the five peaks, namely Main, Central and South, directly on the border, and the peaks West and Kangbachen in Nepal's Taplejung District.
Massif
A massif (pronmæˈsiːf or ˈmæsɪf) is simply a principal mountain mass, for example, a compact portion of a mountain range, containing one or more summits (See for example, France's Massif Central.). In mountaineering literature, a massif is frequently used to denote the main mass of an individual mountain. As a purely scientific term in geology, however, a "massif" is separately and more specifically defined as a section of a planet's crust that is demarcated by faults or flexures.
Manaslu
Manaslu (məˈnɑːsluː; मनास्लु, also known as Kutang) is the eighth-highest mountain in the world at above sea level. It is in the Mansiri Himal, part of the Nepalese Himalayas, in the west-central part of Nepal. The name Manaslu means "mountain of the spirit" and is derived from the Sanskrit word manasa, meaning "intellect" or "soul". Manaslu was first climbed on May 9, 1956, by Toshio Imanishi and Gyalzen Norbu, members of a Japanese expedition.
Effects of high altitude on humans
The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around above sea level, the saturation of oxyhemoglobin begins to decrease rapidly. However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen.
Tengboche
Tengboche (or Thyangboche) is a village in Khumbu Pasanglhamu rural municipality in the Khumbu subregion of Province No. 1 in Nepal, located at . In the village is an important Buddhist monastery, Tengboche Monastery, which is the largest gompa in the Khumbu region. The structure was built in 1923. In 1934, it was destroyed by an earthquake but subsequently rebuilt. It was destroyed again by a fire in 1989, and again rebuilt with the help of volunteers and the provision of foreign aid.
