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

Shining Tor
–
Shining Tor is a hill in the Peak District of England, between the towns of Buxton and Macclesfield, lying on the border between Derbyshire and Cheshire. Its summit is the highest point in modern Cheshire, with Black Hill near Crowden being the county top of Cheshire. The word tor means a rock, and is a loan word from Old Brythonic. The hill can be climbed by many routes, perhaps most commonly from the Goyt valley by Errwood reservoir and it can also be gained with less climbing from the Cat and Fiddle Inn. In very clear but not unusual conditions North Wales and even Snowdonia can be seen, the north–south ridge of Shining Tor including the summit itself is formed from the Chatsworth Grit, a thick sandstone of Namurian age which occurs widely across the Peak District. The beds dip moderately steeply to the east into a north–south-aligned syncline known as the Goyt Trough, Shining Tor is thought to have stood above the ice sheet during the last ice age and so is free from glacial deposits. The eastern dipslope and shallower parts of its flanks are covered by peat up to several metres deep

Staffordshire
–
Staffordshire is a landlocked county in the West Midlands of England. It adjoins Cheshire to the north west, Derbyshire and Leicestershire to the east, Warwickshire to the south east, West Midlands and Worcestershire to the south, and Shropshire to the west. The largest city in Staffordshire is Stoke-on-Trent, which is administered separately from the rest of the county as an independent unitary authority, Lichfield also has city status, although this is a considerably smaller cathedral city. Major towns include Stafford, Burton upon Trent, Cannock, Newcastle-under-Lyme, Leek, smaller towns include Stone, Uttoxeter, and Rugeley, and large villages Eccleshall, Wombourne, Kinver, Penkridge, Tutbury and Stretton. Cannock Chase AONB is within the county as well as parts of the National Forest, Wolverhampton, Walsall, West Bromwich, and Smethwick were historic Staffordshire towns until local government reorganisation created the West Midlands county in 1974. Historically, Staffordshire was divided into the five hundreds of Cuttlestone, Offlow, Pirehill, Seisdon, the historic boundaries of Staffordshire cover much of what is now the metropolitan county of West Midlands. The Act also saw the towns of Tamworth and Burton upon Trent united entirely in Staffordshire, in 1553 Queen Mary made Lichfield a county separate from the rest of Staffordshire. Handsworth and Perry Barr became part of the county borough of Birmingham in the early 20th century, Burton, in the east of the county, became a county borough in 1901, and was followed by Smethwick, another town in the Black Country in 1907. In 1910 the six towns of the Staffordshire Potteries, including Hanley, a major reorganisation in the Black Country in 1966, under the recommendation of the Local Government Commission for England led to the creation of an area of contiguous county boroughs. Meanwhile, the county borough of Dudley, historically a part of Worcestershire, expanded. County boroughs were abolished, with Stoke becoming a district in Staffordshire. On 1 April 1997, under a recommendation of the Banham Commission, in July 2009 the largest hoard of Anglo-Saxon gold ever found in Britain was discovered in a field near Lichfield. The artefacts, known as The Staffordshire Hoard have tentatively dated to the 7th or 8th centuries. Some nationally and internationally known companies have their base in Staffordshire. They include the Britannia Building Society which is based in Leek, JCB is based in Rocester near Uttoxeter and bet365 based in Stoke-on-Trent. The theme park Alton Towers is in the Staffordshire Moorlands and several of the worlds largest pottery manufacturers are based in Stoke-on-Trent, Staffordshire has a completely comprehensive system with eight independent schools. Most secondary schools are from 11–16 or 18, but two in Staffordshire Moorlands and South Staffordshire are from 13–18, there are two universities in the county, Keele University in Newcastle-under-Lyme and Staffordshire University, which has campuses in Stoke-on-Trent, Stafford, Lichfield and Shrewsbury. The modern county of Staffordshire currently has three football clubs – Stoke City and Port Vale, both from Stoke-on-Trent, and Burton Albion, who play in Burton upon Trent. They were among the 12 founder members of the Football League in 1888, in 1972, the club finally won a major trophy when they lifted the Football League Cup, but after relegation from the First Division in 1985 they would not experience top flight football for 23 years

England
–
England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west, the Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east, the country covers five-eighths of the island of Great Britain in its centre and south, and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. England became a state in the 10th century, and since the Age of Discovery. The Industrial Revolution began in 18th-century England, transforming its society into the worlds first industrialised nation, Englands terrain mostly comprises low hills and plains, especially in central and southern England. However, there are uplands in the north and in the southwest, the capital is London, which is the largest metropolitan area in both the United Kingdom and the European Union. In 1801, Great Britain was united with the Kingdom of Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain, the name England is derived from the Old English name Englaland, which means land of the Angles. The Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages, the Angles came from the Angeln peninsula in the Bay of Kiel area of the Baltic Sea. The earliest recorded use of the term, as Engla londe, is in the ninth century translation into Old English of Bedes Ecclesiastical History of the English People. According to the Oxford English Dictionary, its spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, the etymology of the tribal name itself is disputed by scholars, it has been suggested that it derives from the shape of the Angeln peninsula, an angular shape. An alternative name for England is Albion, the name Albion originally referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus, specifically the 4th century BC De Mundo, in it are two very large islands called Britannia, these are Albion and Ierne. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, the word Albion or insula Albionum has two possible origins. Albion is now applied to England in a poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England, Lloegr, the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximately 780,000 years ago. The oldest proto-human bones discovered in England date from 500,000 years ago, Modern humans are known to have inhabited the area during the Upper Paleolithic period, though permanent settlements were only established within the last 6,000 years

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

Peak District
–
The Peak District is an upland area in England at the southern end of the Pennines. It is mostly in northern Derbyshire, but also parts of Cheshire, Greater Manchester. The Peak District National Park became the first national park in the United Kingdom in 1951, with its proximity to the cities of Manchester, Stoke-on-Trent, Derby and Sheffield and easy access by road and rail, it attracts millions of visitors every year. The Peak District forms the end of the Pennines and much of the area is uplands above 1,000 feet. Despite its name, the landscape generally lacks sharp peaks, being characterised by rounded hills, the area is surrounded by major conurbations, including Huddersfield, Manchester, Sheffield, Derby and Stoke-on-Trent. The National Park covers 555 square miles of Derbyshire, Staffordshire, Cheshire, Greater Manchester and South and West Yorkshire, including the majority of the area commonly referred to as the Peak. Its northern limits lie along the A62 road between Marsden and Meltham, north east of Oldham, while its southernmost point is on the A52 road on the outskirts of Ashbourne in Derbyshire. The town of Bakewell and numerous villages are included within the boundaries, as of 2010, it is the fifth largest National Park in England and Wales. 12% of the Peak District National Park is owned by the National Trust and it does not receive government funding. The Peak District National Park Authority directly owns around 5%, the Peak District is formed almost exclusively from sedimentary rocks dating from the Carboniferous period. They comprise the Carboniferous Limestone, the overlying Gritstone and finally the Coal Measures, in addition there are infrequent outcrops of igneous rocks including lavas, tuffs and volcanic vent agglomerates. The general geological structure of the Peak District is that of a broad dome, the southern edge of the dome is overlain by sandstones of Triassic age though these barely impinge upon the National Park. Earth movements after the Carboniferous period resulted in the up-doming of the area and, particularly in the west, the region was raised in a north–south line which resulted in this dome-like shape and the shale and sandstone were worn away until limestone was exposed. At the end of period, the Earths crust sank here which led to the area being covered by sea. Some time after its deposition, mineral veins were formed in the limestone and these veins and rakes have been mined for lead since Roman times. The Peak District was covered by ice during at least one of the ice ages of the last 2 million years as evidenced by the patches of glacial till or boulder clay that can be found across the area. It was not covered by ice during the last glacial period, a mix of Irish Sea and Lake District ice abutted against its western margins. Glacial meltwaters eroded a complex of channels along this margin of the Peak District during this period

Ordnance Survey National Grid
–
The Ordnance Survey National Grid reference system is a system of geographic grid references used in Great Britain, different from using Latitude and Longitude. It is often called British National Grid, the Ordnance Survey devised the national grid reference system, and it is heavily used in their survey data, and in maps based on those surveys. Grid references are commonly quoted in other publications and data sources. The Universal Transverse Mercator coordinate system is used to provide references for worldwide locations. European-wide agencies also use UTM when mapping locations, or may use the Military Grid Reference System system, the grid is based on the OSGB36 datum, and was introduced after the retriangulation of 1936–1962. It replaced the previously used Cassini Grid which, up to the end of World War Two, had issued only to the military. The Airy ellipsoid is a regional best fit for Britain, more modern mapping tends to use the GRS80 ellipsoid used by the GPS, the British maps adopt a Transverse Mercator projection with an origin at 49° N, 2° W. Over the Airy ellipsoid a straight grid, the National Grid, is placed with a new false origin. This false origin is located south-west of the Isles of Scilly, the distortion created between the OS grid and the projection is countered by a scale factor in the longitude to create two lines of longitude with zero distortion rather than one. Grid north and true north are aligned on the 400 km easting of the grid which is 2° W. 2° 0′ 5″ W. OSGB36 was also used by Admiralty nautical charts until 2000 after which WGS84 has been used, a geodetic transformation between OSGB36 and other terrestrial reference systems can become quite tedious if attempted manually. The most common transformation is called the Helmert datum transformation, which results in a typical 7 m error from true, the definitive transformation from ETRS89 that is published by the OSGB is called the National Grid Transformation OSTN02. This models the detailed distortions in the 1936–1962 retriangulation, and achieves backwards compatibility in grid coordinates to sub-metre accuracy, the difference between the coordinates on different datums varies from place to place. The longitude and latitude positions on OSGB36 are the same as for WGS84 at a point in the Atlantic Ocean well to the west of Great Britain. In Cornwall, the WGS84 longitude lines are about 70 metres east of their OSGB36 equivalents, the smallest datum shift is on the west coast of Scotland and the greatest in Kent. But Great Britain has not shrunk by 100+ metres, a point near Lands End now computes to be 27.6 metres closer to a point near Duncansby Head than it did under OSGB36. For the first letter, the grid is divided into squares of size 500 km by 500 km, there are four of these which contain significant land area within Great Britain, S, T, N and H. The O square contains an area of North Yorkshire, almost all of which lies below mean high tide
