Lingtren
Lingtren, , is a mountain in the Mahalangur Himal area of Himalaya, about distant in a direct line from Mount Everest. It lies on the international border between Nepal and the Tibet Autonomous Region of China and it was first climbed in 1935. A mountain nearby to the west was originally named Lingtrennup but is now more commonly called Xi Lingchain. Geography A long chain of mountains extends generally somewhat north of west from Mount Everest whose west ridge descends to the col of Lho La () before rising to Khumbutse (). The ridge drops to an unnamed col at and then ascends to Lingtren from where it continues to another unnamed col at and then to Pumori (). Bounded on the north by this chain of mountains is the Western Cwm in Nepal down which the Khumbu Glacier descends to the northwest over the Icefall before it turns sharply southwest. Lingtren lies at the apex of this right-angled bend. North of the mountain chain in Tibet the West Rongbuk Glacier flows east to join ...

Pumori
Pumori ( ne, पुमोरी, ) (or Pumo Ri) 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. Pumori is a popular climbing peak. The easiest route is graded class 3, although with significant avalanche danger. Pumori was first climbed on May 17, 1962, by Gerhard Lenser on a German-Swiss expedition. Two Czechs (Leopold Sulovský and Zdeněk Michalec) climbed a new route on the south face in the spring of 1996. An outlier of Pumori is Kala Patthar (), which appears as a brown bump below the south face of Pumori. Many trekkers going to see Mount Everest up close will attempt to climb to the top of Kala Pattha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1921 British Mount Everest Reconnaissance Expedition
The 1921 British Mount Everest reconnaissance expedition set off to explore how it might be possible to get to the vicinity of Mount Everest, to reconnoitre possible routes for ascending the mountain, and – if possible – make the first ascent of the highest mountain in the world. At that time Nepal was closed to foreigners, so any approach had to be from the north, through Tibet. A feasible route was discovered from the east up the Kharta Glacier and then crossing the Lhakpa La pass north east of Everest. It was then necessary to descend to the East Rongbuk Glacier before climbing again to Everest's North Col. However, although the North Col was reached, it was not possible to climb further before the expedition had to withdraw. Initially the expedition explored from the north and discovered the main Rongbuk Glacier, only to find that it seemed to provide no likely routes to the summit. However, at the time it was not realised that the East Rongbuk glacier actually flowed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dan Bryant (mountaineer)
Leslie Vickery Bryant, known as Dan Bryant (29 March 1905 – 10 December 1957), was a New Zealand school teacher and a mountain climber. He was a member of the 1935 British Mount Everest reconnaissance expedition, which was a preliminary to the full expedition of 1936 that attempted the summit. However in 1935 Bryant did not acclimatise well to altitude above , and so was not included in the party for 1936. He was a very accomplished ice climber, and was well-liked on expeditions. These two factors led, indirectly, to his compatriot Edmund Hillary becoming a member of the successful 1953 British Mount Everest expedition. Teaching and New Zealand climbing Born in 1905, Dan Bryant graduated at the University of Auckland in 1927 and his first job was at New Plymouth Boys' High School, near the Mount Taranaki (known in his day as Mount Egmont). He was a keen mountaineer and took parties of school pupils on expeditions on the mountain. After four years he moved to South Island a ...

Khumbutse
Khumbutse () is the first mountain west (6 km) of Mount Everest. It lies at the border between Nepal and China. Overview Khumbutse's name indicates its location at the head of the Khumbu valley, down which the Khumbu Glacier flows. It is one of the prominent mountains above the southern Everest Base Camp, and is seen in many views from the nearby trekking routes, including at Gorak Shep.

Khumbu
Khumbu (also known as the Everest Region) is a region of northeastern Nepal on the Nepalese side of Mount Everest. It is part of the Solukhumbu District, which in turn is part of Province No. 1.Bradley, Mayhew; "Trekking in the Nepal Himalaya"; (2009); 9 edição; pp 84-141; Lonely Planet; . Khumbu is one of three subregions of the main Kirat Kulung and Sherpa settlement of the Himalaya, the other two being Solu and Pharak. It includes the town of Namche Bazaar as well as the villages of Thame, Khumjung, Pangboche, Pheriche and Kunde. The famous Buddhist monastery at Tengboche is also located in the Khumbu. The Khumbu's elevation ranges from 3,300 metres (11,000 feet) to the 8,848.86 m (29,032 ft) summit of Mount Everest, the highest place on Earth. The Khumbu region includes both Sagarmatha National Park (above Monju) and the Sagarmatha National Park Buffer Zone, between Lukla and Monju.

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. A peak's ''key col'' (the highest col surrounding the peak) is a unique point on this contour line and the ''parent peak'' is some higher mountain, selected according to various criteria. Definitions The prominence of a peak may be defined as the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following way: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''key Saddle point, saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting pat ...

Digital Elevation Model
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally produced relief maps. A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs. While a DSM may be useful for landscape modeling, city modeling and visualization applications, a DTM is often required for flood or drainage modeling, land-use studies, geological applications, and other applications, and in planetary science. Terminology There is no universal usage of the terms ''digital elevation model'' (DEM), ''digital terrain model'' (DTM) and ''digital surface model'' (DSM) in scientific literature. In most cases the term ''digital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intrusion (geology)
Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form '' intrusions'', such as batholiths, dikes, sills, laccoliths, and volcanic necks.Intrusive RocksIntrusive rocks accessdate: March 27, 2017.Igneous intrusive rocks, accessdate: March 27, 2017.Britannica.comintrusive rock , geology , Britannica.com accessdate: March 27, 2017. Intrusion is one of the two ways igneous rock can form. The other is extrusion, such as a volcanic eruption or similar event. An intrusion is any body of intrusive igneous rock, formed from magma that cools and solidifies within the crust of the planet. In contrast, an ''extrusion'' consists of extrusive rock, formed above the surface of the crust. Some geologists use the term plutonic rock synonymously with intrusive rock, but other geologists subdivide intrusive rock, by crystal size, into coarse-grained plutonic rock (typically formed deeper in the Earth's crust in batholiths or stocks) an ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Sill (geology)
In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A ''sill'' is a ''concordant intrusive sheet'', meaning that a sill does not cut across preexisting rock beds. Stacking of sills builds a sill complex . and a large magma chamber at high magma flux. In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock. These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existing bedding pla ...

Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture ...
