Mountains Of The Central Dingle Peninsula
The Mountains of the Central Dingle Peninsula are the generic name given to the mountains that lie on the Dingle Peninsula between the Brandon Group of mountains in the west, and the Slieve Mish Mountains at the eastern end of the peninsula. Geology Like many of the mountain ranges in Kerry, such as the MacGillycuddy Reeks, the mountains of the Central Dingle peninsula are composed predominantly of Devonian period Old Red Sandstone, with a band of Ordovician period metasediments. The rocks date from the Upper Devonian period (310–450 million years ago) when Ireland was in a hot equatorial setting. During this 60 million year period, Ireland was the site of a major basin, known as the Munster basin, and Cork and Kerry were effectively a large alluvial floodplain. Chemical oxidation stained the material with a purple–reddish colour (and green in places from chlorination), still visible today. There are virtually no fossils in Old Red Sandstone. The composition of Old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beenoskee
Beenoskee or Benoskee () is a 826 m (2,710 ft) mountain on the Dingle Peninsula in Kerry, Ireland. Geography Beenoskee is part of the Dingle Mountains, and is the highest of the "Central Dingle" group and the 28th highest in Ireland. It is within the Gaeltacht. Beenoskee is the highest peak of the Central Dingle massif, which also includes the peaks of Stradbally Mountain (798m), Coumbaun (610m) and Beenatoor (592m). Between Beenoskee and Stradbally is a small lake called Loch an Choimín (anglicised Lough Acummeen), which sits at a height of 816m.

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ordnance Survey Ireland
Ordnance Survey Ireland (OSI; ga, Suirbhéireacht Ordanáis Éireann) is the national mapping agency of Ireland. It was established on 4 March 2002 as a body corporate. It is the successor to the former Ordnance Survey of Ireland. It and the Ordnance Survey of Northern Ireland (OSNI) are the ultimate successors to the Irish operations of the British Ordnance Survey. OSI is part of the Irish public service. OSI has made modern and historic maps of the state free to view on its website. OSI is headquartered at Mountjoy House in the Phoenix Park in Dublin. Mountjoy House was also the headquarters, until 1922, of the Irish section of the British Ordnance Survey. Organisation Under the Ordnance Survey Ireland Act 2001, the Ordnance Survey of Ireland was dissolved and a new corporate body called Ordnance Survey Ireland was established in its place. OSI is now an autonomous corporate body, with a remit to cover its costs of operation from its sales of data and derived products, wh ...

Topographic Map
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large- scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system. Natural Resources Canada provides this description of topographic maps: Other authors define topographic maps by contrasting them with anot ...

Summit
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topography, 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 Edm ...

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 ...

Elevation
The elevation of a geographic 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 surface (see 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 '' 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 have, respectively, the largest elevation and the largest geocentric distance. Aviation In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lists Of Mountains And Hills In The British Isles
The mountains and hills of the British Isles are categorised into various lists based on different combinations of elevation, prominence, and other criteria such as isolation. These lists are used for peak bagging, whereby hillwalkers attempt to reach all the summits on a given list, the oldest being the 282 Munros in Scotland, created in 1891. A height above 2,000 ft, or more latterly 610 m, is considered necessary to be classified as a mountain – as opposed to a hill – in the British Isles. With the exception of Munros, all the lists require a prominence above . A prominence of between (e.g. some Nuttalls and Vandeleur-Lynams), does not meet the International Climbing and Mountaineering Federation (UIAA) definition of an "independent peak", which is a threshold over . Most lists consider a prominence between as a "top" (e.g. many Hewitts and Simms). Marilyns, meanwhile, have a prominence above , with no additional height threshold. They range from small hills to ... [...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] |
U-shaped Valley
U-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. They have a characteristic U shape in cross-section, with steep, straight sides and a flat or rounded bottom (by contrast, valleys carved by rivers tend to be V-shaped in cross-section). Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring. When the ice recedes or thaws, the valley remains, often littered with small boulders that were transported within the ice, called glacial till or glacial erratic. Examples of U-shaped valleys are found in mountainous regions throughout the world including the Andes, Alps, Caucasus Mountains, Himalaya, Rocky Mountains, New Zealand and the Scandinavian Mountains. They are found also in other major European mountains including the Carpathian Mountains, the Pyrenees, the Rila and Pirin mountains in Bulgaria, an ...
