Dunkery Hill
Dunkery Beacon at the summit of Dunkery Hill is the highest point on Exmoor and in Somerset, England. It is also the highest point in southern England outside of Dartmoor. The sandstone hill rises to and provides views over the surrounding moorland, the Bristol Channel and hills up to away. The site has been visited by humans since the Bronze Age, and contains several burial mounds in the form of cairns and bowl barrows. Sweetworthy on the lower slopes is the site of two Iron Age hill forts or enclosures and a deserted medieval settlement. The hill is part of a Site of Special Scientific Interest and National nature reserve. It was in private ownership until the 20th century, when it was donated to the National Trust by Sir Thomas Acland, Colonel Wiggin and Allan Hughes; a stone cairn was erected at the summit to commemorate the event. Location Dunkery is composed of Middle Devonian sedimentary rock, () known as the Hangman Sandstone Formation. This supports acidic s ...

High Willhays
High Willhays ( , ), or according to some authorities High Willes, is the highest point on Dartmoor, Devon, at above sea level,Dartmoor National Park Authority, General Information: Dartmoor Factsheet', 2004, p. 1 and the highest point in Southern England. Toponymy In 1912, William Crossing, writer and documenter, said that the name ''High Willes'' had been thought to have derived from the word ''huel'' or ''wheal'' meaning ''mine'', but he did not think that very likely as old mine workings were invariably located near to streams. He suggested instead that the name derived from ''gwylfa'', a watching place, noting its similarity with ''Brown Willy'', the name of the highest hill on nearby Bodmin Moor, and suggested that a watch for Beacon#For defensive communications, beacon fires used to be kept here. He also posited a possible link to the word ''gwili'' meaning winding or tortuous, but said it was unlikely this was where it originated from. ''The Place-Names of Devon'' ( ...

National Nature Reserve (United Kingdom)
Some statutory nature reserves are designated by national bodies in the United Kingdom, and are known as national nature reserves. Great Britain In Great Britain, nature reserves designed under Part III of the National Parks and Access to the Countryside Act 1949 that are deemed to be of national importance may be designated as statutory 'national nature reserves' by the relevant national nature conservation body (Natural England, Scottish Natural Heritage, or Natural Resources Wales) using section 35(1) of the Wildlife and Countryside Act 1981. If a nature reserve is designated by a local authority in Great Britain, then the resulting statutory nature reserve will be referred to as a local nature reserve. England In England, 229 national nature reserves are designated by Natural England. Scotland In Scotland, 43 national nature reserves are designated by NatureScot. Wales In Wales, 76 national nature reserves are designated by Natural Resources Wales. Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorna Doone
''Lorna Doone: A Romance of Exmoor'' is a novel by English author Richard Doddridge Blackmore, published in 1869. It is a romance based on a group of historical characters and set in the late 17th century in Devon and Somerset, particularly around the East Lyn Valley area of Exmoor. In 2003, the novel was listed on the BBC's survey The Big Read. Publication history Blackmore experienced difficulty in finding a publisher, and the novel was first published anonymously in 1869, in a limited three-volume edition of just 500 copies, of which only 300 sold. The following year it was republished in an inexpensive one-volume edition and became a huge critical and financial success. It has never been out of print. Reception It received acclaim from Blackmore's contemporary, Margaret Oliphant, and as well from later Victorian writers including Robert Louis Stevenson, Gerard Manley Hopkins, and Thomas Hardy. George Gissing wrote in a letter to his brother Algernon that the novel was "qui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yes Tor
Yes Tor is the second highest point on Dartmoor, Devon, South West England, at above sea level. It is one of only two wholly English peaks south of the Peak District National Park—the other being nearby High Willhays—that are above . It lies within a British Army firing range and safe access is only possible on days or nights when firing is not taking place. See the current Dartmoor Firing Notice. Yes Tor is lower than the nearby High Willhays. A notable mine is located in the area. In literature In his memoir ''Father and Son'' (1907), ''Edmund Gosse'' views Yes Tor, near which he lived when a boy, as an unthreatening and unprepossessing hill: "Alas! We might as well have attempted to rouse the summit of Yes Tor into volcanic action." US science fiction author Kim Stanley Robinson makes an oblique reference to Yes Tor in his novel '' 2312'', commingled with a variety of then-historical musical contextual clues. In popular culture Yes Tor was the original inspiration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relative Height
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 ...

List Of Marilyns In England
This is a list of Marilyn hills and mountains in the United Kingdom, Isle of Man and Ireland by height. Marilyns are defined as peaks with a prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,011 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophonous with (Marilyn) '' Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Marilyn was the first of several subsequent British Isles classifications that rely solely on prominence, including the P600s, the HuMPs, and the TuMPs. Topographic prominence is a more difficult to estimate than to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mendip TV Mast
The Mendip transmitting station is a broadcasting and telecommunications facility on the summit of Pen Hill, part of the Mendip Hills range in Somerset, England, at above sea level. The station is in St Cuthbert Out civil parish in Mendip district, approximately northeast of the centre of Wells. It has a tall mast, which was built in 1967 and weighs around 500 tonnes, and is the tallest structure in South West England. The mast broadcasts digital television, FM analogue radio and DAB digital radio, and had broadcast analogue colour television from 1967 until 2010. It has become a Mendip landmark, providing a method of identifying the hills from a distance. Description The station is owned and operated by Arqiva (which acquired National Grid Wireless, previously Crown Castle). Until 2008 a GRP aerial cylinder, containing the analogue television transmitting antennas, was mounted at the top of the mast, bringing the total height of the structure to . With a mean hei ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Ordnance Datum
In the British Isles, an ordnance datum or OD is a vertical datum used by an ordnance survey as the basis for deriving altitudes on maps. A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. In particular: * In Great Britain, OD for the Ordnance Survey is ODN (Ordnance Datum Newlyn), defined as the MSL as recorded by the tidal gauge at Newlyn in Cornwall between 1915 and 1921. **Prior to 1921, OD was defined as MSL as recorded in the Victoria Dock, Liverpool, during a short period in 1844 (ODL). * In Northern Ireland, OD for the Ordnance Survey of Northern Ireland is Belfast Ordnance Datum, the MSL at Clarendon Dock, Belfast, between 1951 and 1956. * In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the MSL at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969.

Exmoor Group
The Exmoor Group is a late Devonian to early Carboniferous lithostratigraphic group (a sequence of rock strata) in southwest England whose outcrop extends from Croyde in north Devon east across Exmoor to Minehead in west Somerset. The group comprises the following formations (in stratigraphic order, i.e., the oldest at the base and the youngest at the top) the: *Pilton Mudstone Formation (Pilton Beds, Pilton Shales) *Baggy Sandstones Formation (Baggy Beds, Marwood Beds) *Upcott Slates Formation *Pickwell Down Sandstones Formation *Morte Slates Formation *Ilfracombe Slates Formation *Hangman Sandstone Formation (Hangman Grits) *Lynton Formation (Lynton Beds, Lynton Slates) Each of these divisions has been given different names by different authors in the past including those shown in brackets above. Some that had been classed as 'formations' (or even in one case as a 'group') are now ' members'. Lynton Formation Extending east from Woody Bay, the Lynton Formation underlies the ...

Sedimentary
Sedimentary rocks are types of rock (geology), rock that are formed by the accumulation or deposition of mineral or organic matter, organic particles at Earth#Surface, Earth's surface, followed by cementation (geology), cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of detritus (geology), geological detritus (minerals) or detritus, biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...
