Mount McKinley
Denali (), federally designated as Mount McKinley, is the highest mountain peak in North America, with a summit elevation of above sea level. It is the tallest mountain in the world from base to peak on land, measuring . On p. 20 of Helman (2005):"the base to peak rise of Mount McKinley is the largest of any mountain that lies entirely above sea level, some ". With a topographic prominence of and a topographic isolation of , Denali is the third most prominent and third-most isolated peak on Earth, after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve. The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley, who later became the 25th president; McKinley's name was the official name recogni ...

Robert Tatum
Robert George Tatum (August 20, 1891 – January 27, 1964) was an American mountain climber and Episcopal priest. He, along with Hudson Stuck, Harry Karstens, and Walter Harper made up the expedition that was the first to successfully climb Denali, the tallest mountain in North America, on June 7, 1913. Early life Tatum was born on August 20, 1891, in Knoxville, Tennessee, the son of George, a photographer, and Emma Tatum. He grew up in Knoxville, and went to Sewanee: The University of the South. In June 1911 he moved to Nenana, Alaska, to visit his brother Howard, who was working at an Army outpost. That summer, Robert worked as a surveyor for the government; after that he taught at an Episcopalian mission school. Denali expedition Episcopalian archdeacon Hudson Stuck, who would later become the expedition leader, first met Tatum during a regular visit to the mission school. Stuck asked Tatum if he would join him in ascending Denali (Mount McKinley) for the first time; he im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koyukon People
The Koyukon, Dinaa, or Denaa ( Denaakk'e: ''Tl’eeyegge Hut’aane'') are an Alaska Native Athabascan people of the Athabascan-speaking ethnolinguistic group. Their traditional territory is along the Koyukuk and Yukon rivers where they subsisted for thousands of years by hunting and trapping. Many Koyukon live in a similar manner today. The Koyukon language belongs to a large family called Na-Dené or Athabascan, traditionally spoken by numerous groups of native people throughout northwestern North America. In addition, due to ancient migrations of related peoples, other Na-Dené languages, such as Navajo and Apachean varieties, are spoken in the American Southwest and in Mexico. History The first Europeans to enter Koyukon territory were Russians, who came up the Yukon River to Nulato in 1838. When they arrived, they found that items such as iron pots, glass beads, cloth apparel, and tobacco had already reached the people through their trade with coastal Eskimos, w ...

Mount Everest
Mount Everest (), known locally as Sagarmatha in Nepal and Qomolangma in Tibet, is Earth's highest mountain above sea level. It lies in the Mahalangur Himal sub-range of the Himalayas and marks part of the China–Nepal border at its summit. Its height was most recently measured in 2020 by Chinese and Nepali authorities as . 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. As of May 2024, 340 people have died on Everest. Over 200 bodies remain on the mountain and have not been removed due to the dangerous conditions. Climbers typically ascend only part of Mount Eve ...

List Of Peaks By Isolation
The topographic isolation of a summit is the minimum horizontal distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and islands as well as for major mountain peaks and can even be calculated for submarine summits. Mount Everest, the highest point on Earth, has an undefined isolation, since there are no higher points to reference. Because topographic isolation can be difficult to determine, a common approximation is the distance to a peak called the nearest higher neighbour (NHN). Isolation table The following sortable table lists Earth's 40 most topographically isolated summits. Examples *The nearest peak to Germany's highest mountain, the high Zugspitze, that has a contour is the Zwölferkogel in Austria's Stubai Alps. The distance between the Zugspitze and this contour is ; the Zugspitze is thus the highest peak for a radius of . Its isolation is thus . *Because ther ...

List Of Peaks By Prominence
This is a list of mountain peaks ordered by their topographic prominence. Terminology The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. The lowest point on that route is the col. For full definitions and explanations of ''topographic prominence'', ''key col'', and ''parent'', see topographic prominence. In particular, the different definitions of the parent of a peak are addressed at length in that article. ''Height'' on the other hand simply means elevation of the summit above sea level. Regarding parents, the ''prominence parent'' of peak A can be found by dividing the island or region in question into territories, by tracing the runoff from the key col (mountain pass) of every peak that is more prominent than peak A. The parent is the peak whose territory peak A resides in. The ''encirclement parent'' is found by tracing the contour below peak A's key col and picking the hig ...

Topographic Isolation
The topographic isolation of a summit is the minimum geographical distance, horizontal distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and islands as well as for major summit (topography), mountain peaks and can even be calculated for submarine summits. Mount Everest, the highest point on Earth, has an undefined isolation, since there are no higher points to reference. Because topographic isolation can be difficult to determine, a common approximation is the distance to a peak called the nearest higher neighbour (NHN).

Topographic Prominence
In topography, prominence or relative height (also referred to as autonomous height, and shoulder drop in US English, and drop 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'' (if any) is some higher mountain, selected according to various criteria. Definitions The prominence of a peak is 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 manner: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''highest saddle (landform), saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the prominence is the differ ...

List Of Highest Mountains On Earth
There are at least 108 mountains on Earth with elevations of or greater above sea level. Of these, 14 are more than . The vast majority of these mountains are part of either the Himalayas or the Karakoram mountain ranges located on the edge of the Indian Plate and Eurasian Plate in China, India, Nepal, and Pakistan. Discussion The dividing line between a mountain with multiple peaks and separate mountains is not always clear (see also Highest unclimbed mountain). A popular and intuitive way to distinguish mountains from subsidiary peaks is by their height above the highest saddle connecting it to a higher summit, a measure called topographic prominence or re-ascent (the higher summit is called the "parent peak"). A common definition of a mountain is a summit with prominence. Alternatively, a relative prominence (prominence/height) is used (usually 7–8%) to reflect that in higher mountain ranges everything is on a larger scale. The table below lists the highest 100 summit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, 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 Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevation
The elevation of a geographic location (geography), ''location'' is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational equipotential surface, surface (see Geodetic datum#Vertical datum, Geodetic datum § Vertical datum). The term ''elevation'' is mainly used when referring to points on the Earth's surface, while ''altitude'' or ''geopotential height'' is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and ''three-dimensional space, depth'' is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge, the summits of Mount Everest and Chimborazo (volcano), Chimborazo have, respectively, the largest elevation and the largest ECEF, geocentric distance. Aviation In aviation, the term ''elevation'' or ''aerodrome elevation'' is defined by the IC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
