Summit
–
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a maximum in elevation. The topographic terms acme, apex, peak, and zenith are synonymous, the UIAA definition is that a summit is independent if it has a prominence of 30 metres or more, it is a mountain if it has a prominence of at least 300 metres. This can be summarised as follows, 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. In many parts of the western United States, the term refers to the highest point along a road, highway. For example, the highest point along Interstate 80 in California is referred to as Donner Summit while the highest point on Interstate 5 is Siskiyou Mountain Summit, geoid Hill List of highest mountains Maxima and minima Nadir Summit accordance Peak finder

Topographic prominence
–
It is a measure of the independence of a summit. A peaks key col is a point on this contour line. By convention, the prominence of Mount Everest, the Earths highest mountain, is taken to equal the elevation of its summit above sea level, if the peaks prominence is P metres, to get from the summit to any higher terrain one must descend at least P metres. Together with the convention for Mount Everest, this implies that the prominence of any island or continental highpoint is equal to its elevation above sea level, for every ridge connecting the peak to higher terrain, find the lowest point on the ridge. The key col is defined as the highest of these cols, the prominence is the difference between the elevation of the peak and the elevation of the key col. The following mental exercise may illustrate the meaning of topographic prominence, imagine you are standing at the top of a peak and imagine that an imaginary sea level rises to your feet. Now slowly lower the sea level and an imaginary island appears beneath your feet. Your island will grow and will merge with other islands that emerge, the parent peak may be either close or far from the subject peak. The summit of Mount Everest is the parent peak of Aconcagua at a distance of 17,755 km, the key col may also be close or far from the subject peak. The key col for Aconcagua is the Bering Strait at a distance of 13,655 km, the key col for the South Summit of Mount Everest is about 100 m distant. Prominence is interesting to many mountaineers because it is a measurement that is strongly correlated with the subjective significance of a summit. Peaks with low prominences are either subsidiary tops of some higher summit or relatively insignificant independent summits, peaks with high prominences tend to be the highest points around and are likely to have extraordinary views. Only summits with a sufficient degree of prominence are regarded as independent mountains, for example, the worlds second-highest mountain is K2. While Mount Everests South Summit is taller than K2, it is not considered an independent mountain because it is a subsummit of the main summit, many lists of mountains take topographic prominence as a criterion for inclusion, or cutoff. John and Anne Nuttalls The Mountains of England and Wales uses a cutoff of 15 m, in the contiguous United States, the famous list of fourteeners uses a cutoff of 300 ft /91 m. Also in the U. S.2000 feet of prominence has become a threshold that signifies that a peak has major stature. This generates lists of peaks ranked by prominence, which are different from lists ranked by elevation. Such lists tend to emphasize isolated high peaks, such as range or island high points, one advantage of a prominence-ranked list is that it needs no cutoff, since a peak with high prominence is automatically an independent peak

Lists of mountains and hills in the British Isles
–
The mountains and hills of Great Britain, and to a lesser extent Ireland, are the subject of a considerable number of lists that categorise them by height, topographic prominence, or other criteria. They are commonly used as a basis for peak bagging, whereby hillwalkers attempt to reach all the summits on a given list. The oldest and best known of these lists is that of the Munros, mountains in Scotland over 3,000 feet, other well-known lists include the Corbetts, Wainwrights and Marilyns. There is no consensus on the definition of mountain, but in Great Britain. The UK government defines mountain as land over 600 metres for the purposes of freedom of access, in addition, some definitions also include a topographical prominence requirement, typically 100 or 500 feet. In practice, mountains in Scotland are frequently referred to as no matter what their height, as reflected in names such as the Cuillin Hills. In Wales, the distinction is more a term of land use, the Munros are mountains in Scotland over 3,000 ft. The list was compiled by Sir Hugh Munro in 1891. There are 282 Munros and 227 further tops, all of them in the Scottish Highlands, list of Munros The Murdos are an attempt to apply objective criteria to the Munros and their associated tops. They comprise all the summits in Scotland over 3,000 feet with a prominence of at least 30 metres, there are currently 442 Murdos, compared to 282 Munros or 509 Munros plus tops. The list was compiled by Alan Dawson, all Murdos are also Munro Tops, but many Munro Tops fail to qualify as Murdos because of insufficient relative height. Before 1997 there were seven Murdos that were not Munro Tops, all seven were included in the 1997 edition of Munros Tables, plus two non-Murdos, Little Pap on Lochnagar and Knights Peak on Sgurr nan Gillean or a UK top-tier administrative area. There are now 347 Hardys with the recent addition of 5 low lying English coastal estuary islands,61 hill ranges,96 islands and 190 administrative areas,183 are in England,31 in Wales,107 in Scotland and 26 in Northern Ireland. The list was first compiled in the 1990s by Ian Hardy, the Marilyns were supplemented in 2007 by the HuMPs which reduces the Prominence requirement to 100m. The list was compiled by Mark Jackson from a number of sources. There are almost 3,000 British HuMPs, including three in the Channel Islands, More recently, Mark Jackson compiled the TuMPs, a list of all hills in Britain having a prominence of 30 metres. By definition, all Murdos, Corbett Tops, Graham Tops, Hewitts, there are over 16,000 TuMPs, approximately half of that number that did not appear in previously researched lists were researched by Mark Jackson between 2006 and 2009. Since 2012 the list has been published and maintained by the editors of The Database of British and Irish Hills, a list of mountains, over 2, 000-foot-high, in England and Wales was published by Buxton & Lewis in 1986

Marilyn (geography)
–
A Marilyn is a mountain or hill in the United Kingdom, Republic of Ireland or Isle of Man with a prominence of at least 150 metres, regardless of absolute height or other merit. The name was coined as a punning contrast to the designation Munro, used of a Scottish mountain with a height of more than 3,000 feet, which is homophonous with Monroe. There are 2,010 Marilyns identified,1,218 in Scotland,454 in Ireland,175 in England,158 in Wales,5 on the Isle of Man. Black Mountain, in the Black Mountains, on the border between England and Wales, was counted in both countries but is now treated as being in Wales only. The list was extended into Ireland by Clem Clements in a booklet, The Hewitts, however, some lower hills such as Seatallan and Watch Hill on the edges of Lakeland and the Long Mynd in Shropshire do qualify because of their isolation from higher hills. At the other extreme are Stac Lee and Stac an Armin, nearly 80% of Marilyns in Great Britain are in Scotland. They logically extend earlier Scottish lists such as the Munros, Corbetts, Grahams, all Corbetts and Grahams,203 of the 282 Munros, and around half of the Donalds are also Marilyns. Some hillwalkers attempt to climb as many Marilyns as possible, some amateur radio operators attempt to operate from the summit of every Marilyn. Eddie Dealtry became the person to achieve Woodalls feat, later on the same day. By 28 September 2016, the Marilyns of Great Britain had been completed by 10 hillwalkers, while 320 had entered the Marilyn Hall of Fame by attaining a count of at least 600

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Irish language
–
Irish, also referred to as Gaelic or Irish Gaelic, is a Goidelic language of the Indo-European language family originating in Ireland and historically spoken by the Irish people. Irish is spoken as a first language by a minority of Irish people. Irish enjoys constitutional status as the national and first official language of the Republic of Ireland and it is also among the official languages of the European Union. The public body Foras na Gaeilge is responsible for the promotion of the language throughout the island of Ireland and it has the oldest vernacular literature in Western Europe. The fate of the language was influenced by the power of the English state in Ireland. Elizabethan officials viewed the use of Irish unfavourably, as being a threat to all things English in Ireland and its decline began under English rule in the 17th century. In the latter part of the 19th century, there was a decrease in the number of speakers. Irish-speaking areas were hit especially hard, by the end of British rule, the language was spoken by less than 15% of the national population. Since then, Irish speakers have been in the minority, efforts have been made by the state, individuals and organisations to preserve, promote and revive the language, but with mixed results. Around the turn of the 21st century, estimates of native speakers ranged from 20,000 to 80,000 people. In the 2011 Census, these numbers had increased to 94,000 and 1.3 million, there are several thousand Irish speakers in Northern Ireland. It has been estimated that the active Irish-language scene probably comprises 5 to 10 per cent of Irelands population, there has been a significant increase in the number of urban Irish speakers, particularly in Dublin. In Gaeltacht areas, however, there has been a decline of the use of Irish. Údarás na Gaeltachta predicted that, by 2025, Irish will no longer be the language in any of the designated Gaeltacht areas. Survey data suggest that most Irish people think highly of Irish as a marker of identity. It has also argued that newer urban groups of Irish speakers are a disruptive force in this respect. In An Caighdeán Oifigiúil the name of the language is Gaeilge, before the spelling reform of 1948, this form was spelled Gaedhilge, originally this was the genitive of Gaedhealg, the form used in Classical Irish. Older spellings of this include Gaoidhealg in Classical Irish and Goídelc in Old Irish, the modern spelling results from the deletion of the silent dh in the middle of Gaedhilge, whereas Goidelic languages, used to refer to the language family including Irish, comes from Old Irish

County Limerick
–
County Limerick is a county in Ireland. It is located in the province of Munster, and is part of the Mid-West Region. It is named after the city of Limerick, Limerick City and County Council is the local council for the county. The countys population at the 2016 census is 195,175 of which 58,319 live in Limerick City, Limerick borders four other counties, Kerry to the west, Clare to the north, Tipperary to the east and Cork to the south. It is the fifth largest of Munsters six counties in size, the River Shannon flows through the city of Limerick into the Atlantic Ocean at the north of the county. Below the city, the waterway is known as the Shannon Estuary, because the estuary is shallow, the countys most important port is several kilometres west of the city, at Foynes. Limerick City is the county town and is also Irelands third largest city and it also serves as a regional centre for the greater Mid-West Region. Newcastle West, Killmallock & Abbeyfeale are other important towns in the county, there are fourteen historic baronies in the county. While baronies continue to be officially defined units, they are no longer used for administrative purposes. Their official status is illustrated by Placenames Orders made since 2003, the highest point in the county is located in its south-east corner at Galtymore, which separates Limerick from County Tipperary. The county is not a simply a plain, its topography consists of hills, the eastern part of the county is part of the Golden Vale, which is well known for dairy produce and consists of rolling low hills. This gives way to flat land around the centre of the county. Towards the west, the Mullaghareirk Mountains push across the county offering extensive views east over the county, tributaries of the Shannon drainage basin located in the county include the rivers Mulkear, Loobagh, Maigue, Camogue, Morning Star, Deel, and the Feale. It is thought that humans had established themselves in the Lough Gur area of the county as early as 3000 BC, the arrival of the Celts around 400 BC brought about the division of the county into petty kingdoms or túatha. The OBriens retained their power until late in the 1100s. The ancestors of both Michael Collins and the famous OConnells of Derrynane were also among the septs of the Uí Fidgenti. As the Ui Fidgenti were the clan in the Limerick after 400 a. d. the Uí Fidgenti still made a substantial contribution to the population of the central. Their capital was Dún Eochair, the earthworks of which still remain and can be found close to the modern town of Bruree

County Tipperary
–
County Tipperary is a county in Ireland. Tipperary County Council is the government authority for the county. It is located in the province of Munster, the county is named after the town of Tipperary, and was established in the early thirteenth century, shortly after the Norman invasion of Ireland. The population of the county was 160,441 at the 2016 census. The largest towns are Clonmel, Nenagh and Thurles, Tipperary is the sixth largest of the 32 counties by area and the 12th largest by population. It is the third largest of Munsters 6 counties by size and it is also the largest landlocked county in Ireland. The region is part of the plain of Ireland, but the diverse terrain contains several mountain ranges, the Knockmealdown, the Galtee, the Arra Hills. Most of the county is drained by the River Suir, the part by tributaries of the River Shannon, the eastern part by the River Nore. No part of the county touches the coast, the centre is known as the Golden Vale, a rich pastoral stretch of land in the Suir basin which extends into counties Limerick and Cork. Parishes were delineated after the Down Survey as a subdivision, with multiple townlands per parish. The civil parishes had some use in local taxation and were included on the nineteenth century maps of the Ordnance Survey of Ireland, for poor law purposes, District Electoral Divisions replaced the civil parishes in the mid-nineteenth century. There are 199 civil parishes in the county, townlands are the smallest officially defined geographical divisions in Ireland, there are 3,159 townlands in the county. Following the Norman invasion of Ireland, the Kingdom of Munster was claimed as a lordship, by 1210, the sheriffdom of Munster shired into the shires of Tipperary and Limerick. In 1328, Tipperary was granted to the Earls of Ormond as a county palatine or liberty, the grant excluded church lands such as the archiepiscopal see of Cashel, which formed the separate county of Cross Tipperary. The county was divided again in 1838. When the Local Government Act 1898 established county councils to replace the grand jury for civil functions and their names were changed from Tipperary North/South Riding to North/South Tipperary by the Local Government Act 2001, which redesignated all administrative counties as simply counties. The Local Government Reform Act 2014 has amalgamated the two counties and restored a single county of Tipperary, following the Local Government Reform Act 2014, Tipperary County Council is the local government authority for the county. The authority is a merger of two separate authorities North Tipperary County Council and South Tipperary County Council which operated up until June 2014

Republic of Ireland
–
Ireland, also known as the Republic of Ireland, is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the part of the island. The state shares its land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint Georges Channel to the south-east, and it is a unitary, parliamentary republic. The head of government is the Taoiseach, who is elected by the Dáil and appointed by the President, the state was created as the Irish Free State in 1922 as a result of the Anglo-Irish Treaty. It was officially declared a republic in 1949, following the Republic of Ireland Act 1948, Ireland became a member of the United Nations in December 1955. It joined the European Economic Community, the predecessor of the European Union, after joining the EEC, Ireland enacted a series of liberal economic policies that resulted in rapid economic growth. The country achieved considerable prosperity between the years of 1995 and 2007, which known as the Celtic Tiger period. This was halted by a financial crisis that began in 2008. However, as the Irish economy was the fastest growing in the EU in 2015, Ireland is again quickly ascending league tables comparing wealth and prosperity internationally. For example, in 2015, Ireland was ranked as the joint sixth most developed country in the world by the United Nations Human Development Index and it also performs well in several national performance metrics, including freedom of the press, economic freedom and civil liberties. Ireland is a member of the European Union and is a member of the Council of Europe. The 1922 state, comprising 26 of the 32 counties of Ireland, was styled, the Constitution of Ireland, adopted in 1937, provides that the name of the State is Éire, or, in the English language, Ireland. Section 2 of the Republic of Ireland Act 1948 states, It is hereby declared that the description of the State shall be the Republic of Ireland. The 1948 Act does not name the state as Republic of Ireland, because to have done so would have put it in conflict with the Constitution. The government of the United Kingdom used the name Eire, and, from 1949, Republic of Ireland, for the state, as well as Ireland, Éire or the Republic of Ireland, the state is also referred to as the Republic, Southern Ireland or the South. In an Irish republican context it is referred to as the Free State or the 26 Counties. From the Act of Union on 1 January 1801, until 6 December 1922, during the Great Famine, from 1845 to 1849, the islands population of over 8 million fell by 30%

Mountain range
–
A mountain range is a geographic area containing numerous geologically related mountains. A mountain system or system of ranges, sometimes is used to combine several geological features that are geographically related. Mountain ranges are usually segmented by highlands or mountain passes and valleys, individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, most geologically young mountain ranges on the Earths land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Andes is 7,000 kilometres long and is considered the worlds longest mountain system. The Alpide belt includes Indonesia and southeast Asia, through the Himalaya, the belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, mountain ranges outside of these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Altai Mountains and the Hijaz Mountains. If the definition of a range is stretched to include underwater mountains. The mountain systems of the earth are characterized by a tree structure, the sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains, equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians. The position of mountains influences climate, such as rain or snow, when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the side, it warms again and is drier. Often, a shadow will affect the leeward side of a range. Mountain ranges are constantly subjected to forces which work to tear them down. Erosion is at work while the mountains are being uplifted and long after until the mountains are reduced to low hills, rivers are traditionally believed to be the principle erosive factor on mountain ranges, with their ability of bedrock incision and sediment transport. The rugged topography of a range is the product of erosion. The basins adjacent to a mountain range are filled with sediments which are buried and turned into sedimentary rock. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example and this mass of rock was removed as the range was actively undergoing uplift
