Bwlch Mawr
Bwlch Mawr is a hill near the northeastern corner of the Llŷn Peninsula in the community of Clynnog in the county of Gwynedd in North Wales. Its name is an odd one for a hill, as it means "big pass" in English. It forms the eastern half of a wider upland area, the highest point of which is the 522 m summit of Gyrn Ddu, though it is Bwlch Mawr on which the Ordnance Survey constructed a trig point. Geology In common with a number of other isolated hills in Llŷn, Bwlch Mawr is formed by an igneous intrusion of Palaeozoic age. Access A single public footpath crosses the southern flanks of the hill but the upper parts of Bwlch Mawr are designated as open country under the Countryside and Rights of Way Act 2000 and therefore freely available to walkers. In the northwest a bridleway A bridle path, also bridleway, equestrian trail, horse riding path, ride, bridle road, or horse trail, is a trail or a thoroughfare that is used by people riding horses, riding on horses.

HuMP
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] |
Trig Point
A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity. The nomenclature varies regionally: they are generally known as trigonometrical stations or triangulation stations in North America, trig points in the United Kingdom, trig pillars in Ireland, trig stations or trig points in Australia and New Zealand, and trig beacons in South Africa. Use The station is usually set up by a government with known coordinates and elevation published. Many stations are located on hilltops for the purposes of visibility. A graven metal plate on the top of a pillar may provide a mounting point for a theodolite or reflector, often using some form of kinematic coupling to ensure reproducible positioning. Trigonometrical stations are grouped together to form a network of triangulation. Positions of all land boundaries, roads, railways, bridges and other ...

Countryside And Rights Of Way Act 2000
The Countryside and Rights of Way Act 2000 (c. 37), known informally as the CRoW Act or "Right to Roam" Act is a United Kingdom Act of Parliament affecting England and Wales which came into force on 30 November 2000. Right to roam The Act implements the so-called "right to roam" (also known as ''jus spatiandi'') long sought by the Ramblers' Association and its predecessors, on certain upland and uncultivated areas of England and Wales. This element of the act was implemented in stages as conclusive maps of different regions were produced. The act refers to areas of 'mountain, moor, heath and down' in addition to registered common land; not all uncultivated land is covered. Rights of way A staged review of public rights of way, including limited rights to create new public footpaths where needed, is being conducted under the Act. Again, this is being conducted in a staged manner, which can produce anomalies – of the two administrative areas of the County of Gloucestershir ...

Freedom To Roam
The freedom to roam, or "everyman's right", is the general public's right to access certain public or privately owned land, lakes, and rivers for recreation and exercise. The right is sometimes called the right of public access to the wilderness or the "right to roam". In Scotland, Finland, Iceland, Norway, Sweden, Estonia, Latvia, Lithuania, Belarus, Austria, Czech Republic and Switzerland, the freedom to roam takes the form of general public rights which are sometimes codified in law. The access is ancient in parts of Northern Europe and has been regarded as sufficiently basic that it was not formalised in law until modern times. However, the right usually does not include any substantial economic exploitation, such as hunting or logging, or disruptive activities, such as making fires and driving offroad vehicles. In countries without such general rights, there may be a network of rights of way, or some nature reserves with footpaths. Europe Nordic countries Ancient traces p ...

Rights Of Way In England And Wales
In England and Wales, other than in the 12 Inner London London boroughs, boroughs and the City of London, the right of way is a legally protected right of the public to pass and re-pass on specific paths. The law in England and Wales differs from Scots law in that rights of way exist only where they are so designated (or are able to be designated if not already), whereas in Scotland any route that meets certain conditions is rights of way in Scotland, defined as a right of way, and in addition, there is a general presumption of access to the countryside ("right to roam"). Private rights of way or easements also exist (see also Highways in England and Wales). Inner London Definitive maps of public rights of way have been compiled for all of England and Wales, as a result of the National Parks and Access to the Countryside Act 1949, except the 12 Inner London boroughs, which, along with the City of London, were not covered by the Act. Definitive maps exist for the Outer London bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeozoic
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean but eve ...

Intrusion
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusions ...

Igneous
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyrn Ddu
Gyrn Ddu is a hill near the northeastern corner of the Llŷn Peninsula in the community of Llanaelhaearn in the county of Gwynedd in North Wales. It forms the western half of a wider upland area, another significant top of which is the 510 m summit of Bwlch Mawr to the east. The distinct northern top of Gyrn Ddu is Gyrn Goch, which attains a height of 492 m. The summit of an eastern top which reaches 491 m is crowned by a prehistoric cairn. To the southwest of Gyrn Ddu is the lower top of Moel Pen-llechog, which reaches a height of 316 m, whilst to the south is the 416 m flat top of Moel Bronmiod. Geology In common with a number of other isolated hills in Llŷn, Gyrn Ddu is formed by an igneous intrusion of Palaeozoic age. The northwestern slopes of Gyn Ddu have been quarried in the past and a number of inclines descend the steep slopes beneath them .

Marilyn (hill)
This is a list of Marilyn hills and mountains in the United Kingdom, Isle of Man and Republic of Ireland, Ireland by height. Lists of mountains and hills in the British Isles#Marilyns, Marilyns are defined as peaks with a topographic prominence, prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Lists of mountains and hills in the British Isles#Munros, 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) ''Marilyn Monroe, Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Marilyn was the first of several subsequen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community (Wales)
A community ( cy, cymuned) is a division of land in Wales that forms the lowest tier of local government in Wales. Welsh communities are analogous to civil parishes in England. There are 878 communities in Wales. History Until 1974 Wales was divided into civil parishes. These were abolished by section 20 (6) of the Local Government Act 1972, and replaced by communities by section 27 of the same Act. The principal areas of Wales are divided entirely into communities. Unlike in England, where unparished areas exist, no part of Wales is outside a community, even in urban areas. Most, but not all, communities are administered by community councils, which are equivalent to English parish councils in terms of their powers and the way they operate. Welsh community councils may call themselves town councils unilaterally and may have city status granted by the Crown. In Wales, all town councils are community councils. There are now three communities with city status: Bangor, St Asaph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llŷn Peninsula
The Llŷn Peninsula ( cy, Penrhyn Llŷn or , ) extends into the Irish Sea from North West Wales, south west of the Isle of Anglesey. It is part of the historic county of Caernarfonshire, and historic region and local authority area of Gwynedd. Much of the eastern part of the peninsula, around Criccieth, may be regarded as part of Eifionydd rather than Llŷn, although the boundary is somewhat vague. The area of Llŷn is about , and its population is at least 20,000. Historically, the peninsula was travelled by pilgrims en route to Bardsey Island (Welsh: ''Ynys Enlli''), and its relative isolation has helped to conserve the Welsh language and culture, for which the locality is now famous. This perceived remoteness from urban life has lent the area an unspoilt image which has made Llŷn a popular destination for both tourists and holiday home owners. Holiday homes remain contentious among locals, many of whom are priced out of the housing market by incomers. From the 1970s to the 199 ...
