Maam Turk
Letterbreckaun () is one of the Maumturk Mountains of Connemara in County Galway, Ireland. At , it is the second-tallest of the Maumturks, the 129th–highest peak in Ireland on the Arderin list, and 159th–highest on the Vandeleur-Lynam list.Mountainviews, (September 2013), "A Guide to Ireland's Mountain Summits: The Vandeleur-Lynams & the Arderins", Collins Books, Cork, Letterbreckaun is in the middle sector of the long north-west to south-east spine of the Maumturks. Naming The anglicised name "Letterbreckaun" comes from ga, Leitir Bhriocáin or ''Leitir Breacáin'' meaning "Brecan's hillside", and is also the name of a townland on the slope of the mountain. Saint Brecan is a saint associated with Galway county, and is said to be the successor to Saint Enda of Aran. Geography Letterbreckaun lies at the northern end of the central sector, of the long north-west to south-east central spine of the Maumturks range, in the Connemara National Park; when viewed from the west, ...

MountainViews Online Database
In these lists of mountains in Ireland, those within Northern Ireland, or on the Republic of Ireland – United Kingdom border, are marked with an asterisk, while the rest are within the Republic of Ireland. Where mountains are ranked by height, the definition of the topographical prominence used to classify the mountain (e.g. the change in elevation required between neighbouring mountains), is noted. In British definitions, a height of is required for a mountain, whereas in Ireland, a lower threshold of is sometimes advocated. The lowest minimum prominence threshold of any definition of an Irish mountain is (e.g. the Vandeleur-Lynam), however most definitions, including the International Climbing and Mountaineering Federation (UIAA) criteria, do not consider prominences below as being mountains (e.g. must at least be an Arderin or a Hewitt). Many British definitions consider a peak with a prominence below , as being a ''top'', and not a mountain (e.g. must be a Marilyn ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Leenaun
Leenaun (), also Leenane, is a village and 1,845 acre townland in County Galway, Ireland, on the southern shore of Killary Harbour and the northern edge of Connemara. Location Leenaun is situated on the junction of the N59 road, and the R336 road in Connemara. Leenaun lies where the deep u-shaped Maam Valley, bounded by the Devilsmother to the east, and the massif of Leenaun Hill to the west, meets Killary Harbour, Ireland's deepest fjord. Across the fjord from the village, is the massif of Ben Gorm, with the larger massif of Mweelrea behind it; while to the east, lie the scenic Aasleagh falls. The village is on the route of the Western Way long-distance trail and the Wild Atlantic Way. Bridge loss and replacement On 18 July 2007, following heavy rain, the only river bridge in the village was swept away, cutting the town in half, and altering some local routes by over 100-kilometres.; the bridge had stood for over 182 years. A permanent replacement bridge was constructed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Féchín Of Fore
Saint Féchín or Féichín (died 665), also known as Mo-Ecca, was a 7th-century Irish saint, chiefly remembered as the founder of the monastery at Fore (''Fobar''), County Westmeath. Sources for his life and legend include Irish annals, martyrologies, genealogies and hagiographical works. Of the two surviving medieval ''Lives'', one was written in Latin, the other in Irish. The Latin ''Life'' was written ''c''. 1400 by Augustine mac Graidín, who belonged to the Saints' Island on the southeastern shore of Lough Ree, south of the present-day village of Newtowncashel. His main source appears to have been a ''Life'' originating in Féchín's monastery on Omey Island. The Irish ''Life'' (''Betha Féchín Fabair'' "The Life of St Féchín of Fore") was written down by Nicol Óg, son of the abbot of Cong, in 1328 and it seems that parts of it go back to even earlier (Latin) sources. The text may be seen as a combination of two texts. The first part is primarily concerned with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruaidhrí Ó Flaithbheartaigh
Roderick O'Flaherty ( ga, Ruaidhrí Ó Flaithbheartaigh; 1629–1718 or 1716) was an Irish historian. Biography He was born in County Galway and inherited Moycullen Castle and estate. O'Flaherty was the last ''de jure'' Lord of Iar Connacht, and the last recognised Chief of the Name of Clan O'Flaherty. He lost the greater part of his ancestral estates to Cromwellian confiscations in the 1650s. The remainder was stolen through deception, by his son's Anglo-Irish father-in-law, Richard ''Nimble Dick'' Martin of Ross. As Martin had given service to some captured Williamite officers he was allowed to keep his lands. It was therefore arranged that to protect them from confiscation 200,000 acres of Connemara lands held by O'Flahertys, Joyces, Lees and others were transferred into Martin's name with the trust they would be returned. However, Martin betrayed his former friends and neighbours and kept all of their lands. Uniquely among the O'Flaherty family up to that time, Roderick ...

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 ...
