Notch (landform)
In geomorphology, a col is the lowest point on a mountain ridge between two peaks.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, p. 103. . It may also be called a gap. Particularly rugged and forbidding cols in the terrain are usually referred to as notches. They are generally unsuitable as mountain passes, but are occasionally crossed by mule tracks or climbers' routes. The term col tends to be associated more with mountain rather than hill ranges. It is derived from the French ''col'' ("collar, neck") from Latin ''collum'', "neck". The height of a summit above its highest col (called the key col) is effectively a measure of a mountain's topographic prominence. Cols lie on the line of the watershed between two mountains, often on a prominent ridge or arête. For example, the highest col in Austria, the ''Obere Glocknerscharte'' ("Upper Glockner Col", ), lies between the Kleinglockner () and Grossglockner () mountains, giving the Kleinglock ...

Key Col
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'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the prom ...

Wind Gap
A wind gap (or air gap) is a gap through which a waterway once flowed that is now dry as a result of stream capture. A water gap is a similar feature, but one in which a waterway still flows. Water gaps and wind gaps often provide routes which, due to their gently inclined profile, are suitable for trails, roads, and railroads through mountainous terrain. Examples of wind gaps in the Blue Ridge Mountains of Virginia include Swift Run Gap, Rockfish Gap, and Buford's Gap. The last was the original crossing of the Blue Ridge Mountains near Bedford for the Virginia and Tennessee Railroad, later the Norfolk and Western Railway, a precursor of today's Norfolk Southern Railway system. Another wind gap with substantial importance in U.S. history is the Cumberland Gap near the junction of Kentucky, Virginia, and Tennessee.

Double Summit
A double summit, double peak, twin summit, or twin peak refers to a mountain or hill that has two summits, separated by a col or saddle. One well-known double summit is Austria’s highest mountain, the Großglockner, where the main summit of the Großglockner is separated from that of the Kleinglockner by the Glocknerscharte col in the area of a geological fault. Other double summits have resulted from geological folding. For example, on Mont Withrow in British Columbia, resistant sandstones form the limbs of the double summit, whilst the softer rock in the core of the fold was eroded.{{cite web , url=http://gsc.nrcan.gc.ca/natmap/cf/intro_e.php , title=Mt.

Grossglockner
The Grossglockner (german: Großglockner ; or just ''Glockner'') is, at 3,798 metres above the Adriatic (12,461 ft), the highest mountain in Austria and the highest mountain in the Alps east of the Brenner Pass. It is part of the larger Glockner Group of the Hohe Tauern range, situated along the main ridge of the Central Eastern Alps and the Alpine divide. The Pasterze, Austria's most extended glacier, lies on the Grossglockner's eastern slope. The characteristic pyramid-shaped peak actually consists of two pinnacles, the ''Grossglockner'' and the Kleinglockner (, from German: ''groß'', "big", ''klein'', "small"), separated by the ''Glocknerscharte'' col. Etymology The name ''Glocknerer'' is first documented in a 1561 map designed by the Viennese cartographer Wolfgang Lazius. The denotation ''Glogger'' is mentioned a 1583 description of the Tyrolean Kals legal district, then referring to the whole ridge south of the Alpine main chain. In the 1760s, the ''Atlas Tyrolens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kleinglockner
At the height of the Kleinglockner is the third highest mountain summit in Austria. However, with a prominence of only 17 metres it is arguable whether it can be counted as an independent mountain, or just as a subpeak of the Großglockner. It lies in the Glockner Group of Austria's Central Alps, the middle section of the Hohe Tauern. Geographically and geologically speaking, it is viewed a secondary summit of the neighbouring Großglockner, but in the literature, in view of its importance to mountaineering, it is in some cases treated as separate. Its peak forms part of the Glockner crest or ridge (''Glocknerkamm'') and lies exactly on the border between the Austrian state of Carinthia and Lienz District in the East Tyrol. The Kleinglockner has the shape of a sharp edge, covered with the so-called Glockner Cornice (''Glocknerwechte'') and, depending on the conditions, can make the ascent of the mountain dangerous to almost impossible. The climbing history of the Kleinglockner is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arête
An arête ( ) is a narrow ridge of rock which separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys. Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. The edge is then sharpened by freeze-thaw weathering, and the slope on either side of the arête steepened through mass wasting Mass wasting, also known as mass movement, is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in ... events and the erosion of exposed, unstable rock. The word ''arête'' () is actually French for "edge" or "ridge"; similar features in the Alps are often described with the German language, German equivalent term ''Grat''. Where three or more cirques meet, a pyramidal peak is created. Cleaver A ''cleaver' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
