Penmoelallt
Penmoelallt or Onllwyn is a hill in the northern part of the county borough of Rhondda Cynon Taff in south Wales. It lies within the Brecon Beacons National Park and Fforest Fawr Geopark. To its east lies the deep valley of Cwm Taf and to its north a rather shallower valley in which the Nant Cadlan originates. To the west is the hill known as Mynydd-y-glog and to the south are slopes draining into the River Taff and the Afon Cynon. The hill culminates in a broken plateau with several knolls rising above the 420m contour. Its afforested nature makes it difficult to determine the precise location of its highest point but this probably lies somewhere around OS grid ref SO 003096. Older maps indicate a spot height of 1376 ft above sea level at SO 000090. Geology Penmoelallt is composed of a layer cake of rocks laid down during the Carboniferous period and subsequently tilted to the south into the South Wales Coalfield basin. Lowermost, and exposed along its northern and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mynydd-y-glog
Mynydd-y-glog is a hill just east of the village of Penderyn in the northern corner of the county borough of Rhondda Cynon Taff in south Wales. It lies within the Brecon Beacons National Park and Fforest Fawr Geopark. Its summit plateau rises to a height of 389m / 1277 ft at OS grid ref SN 982088, a spot marked by a trig point. To its north lies the partly dry valley of Pant Sychbant which forms the eastern extension of Cwm Cadlan. Its southern slopes are drained by various streams which feed into the Afon Cynon. Geology The hill is composed of a layer cake of rocks laid down during the Carboniferous period. Lowermost, and exposed along its shallow northern scarp, are Carboniferous Limestones whilst above these is the coarse Twrch Sandstone (formerly the 'Basal Grit') of the Marros Group (former ' Millstone Grit Series') also dating from the Carboniferous period. A number of northwest to southeast aligned faults runs across the hill. The limestone gives rise to ka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus Leyana
''Sorbus leyana''. Ley's whitebeam, is a species of small tree which is endemic to two sites in southern Wales. It is thought to have arisen by hybridisation of two species of ''Sorbus'', one of which was the rowan. Its closest relatives are some of the other hybrid derived ''Sorbus'' species found in Britain. Description ''Sorbus leyana'' is a shrub or small tree which grows to in the wild, although it will grow taller in cultivation. The best feature distinguishing ''S. leyana'' from its sympatric congeners is by examining the lateral rosette leaves which are normally long and across, meaning that they are 1.2-1.65 times longer than they are wide. These leaves are widest at about the middle and are deeply lobed with the lobes reaching three-quarters of the way to the leaf's midrib and the leaf margin is toothed and normally has 7-10 pairs of leaf veins. The berries are wider than they are long, slightly wider below the middle, with a few small scattered pores and they ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Borough
County borough is a term introduced in 1889 in the United Kingdom of Great Britain and Ireland, to refer to a borough or a city independent of county council control, similar to the unitary authorities created since the 1990s. An equivalent term used in Scotland was a county of city. They were abolished by the Local Government Act 1972 in England and Wales, but continue in use for lieutenancy and shrievalty in Northern Ireland. In the Republic of Ireland they remain in existence but have been renamed ''cities'' under the provisions of the Local Government Act 2001. The Local Government (Wales) Act 1994 re-introduced the term for certain "principal areas" in Wales. Scotland did not have county boroughs but instead had counties of cities. These were abolished on 16 May 1975. All four Scottish cities of the time—Aberdeen, Dundee, Edinburgh, and Glasgow—were included in this category. There was an additional category of large burgh in the Scottish system (similar to a munici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marros Group
The Marros Group is the name given to a suite of rocks of Namurian age laid down during the Carboniferous Period in South Wales. These rocks were formerly known as the Millstone Grit Series but are now distinguished from the similar but geographically separate rock sequences of the Pennines and Peak District of northern England and northeast Wales by this new name. Stratigraphy The Group comprises a thick unit of coarse sandstone known as the Twrch Sandstone (formerly the ‘Basal Grit’) which is overlain by the Bishopston Mudstone and the Telpyn Point Sandstone. The mudstones of these latter two formations was formerly known as the ‘Middle Shales’, a name reflecting the position of this sequence sandwiched between the Basal Grit below and the Farewell Rock, the lowermost sandstone of the South Wales Coal Measures, above. The mudstone itself contains a few bands of sandstone such as the ‘Twelve Foot Sandstone’ and locally the ‘Cumbriense Sandstone’. Likewise the Twrc ...

Brecon Beacons
The Brecon Beacons ( cy, Bannau Brycheiniog, ) are a mountain range in South Wales. In a narrow sense, the name refers to the range of Old Red Sandstone peaks which lie to the south of Brecon. Sometimes referred to as "the central Beacons" they include South Wales' highest mountain, Pen y Fan. The range forms the central section of the Brecon Beacons National Park (), a designation which also encompasses ranges both to the east and the west of "the central Beacons". This much wider area is also commonly referred to as "the Brecon Beacons", and it includes the Black Mountains to the east as well as the similarly named but quite distinct Black Mountain to the west. The highest peaks include Fan Brycheiniog to the west and Pen y Fan in the central part. They share the same basic geology as the central range, and so exhibit many similar features, such as the north-facing escarpment and glacial features such as lakes and cwms ( cirques). Geography The Brecon Beacons range, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taff Trail
The Taff Trail ( cy, Taith Taf) is a popular walking and cycle path that runs for between Cardiff Bay and Brecon in Wales. It is so named because it follows the course of the River Taff. Along much of its length, it follows the National Cycle Network Route 8 ( Lôn Las Cymru) that continues to Holyhead, and is substantially off-road. History The trail was launched in September 1988 by Sir Wyn Roberts, Minister of State for the Welsh Office. The project was initiated and co-ordinated by the Merthyr and Cynon Groundwork Trust, with the co-operation of the local councils through whose areas the trail passes. Financial and logistical support was given by the Welsh Development Agency and by Sustrans, a sustainable transport charity. Before the trail, there were several similar but disconnected routes in the area. Taff Ely borough council had created cycling routes within its boundaries, Cardiff city council had provided the Three Castles Cycle Route from Caerphilly into Cardiff, a ...

Right-of-way (transportation)
A right-of-way (ROW) is a right to make a way over a piece of land, usually to and from another piece of land. A right of way is a type of easement granted or reserved over the land for transportation purposes, such as a highway, public footpath, rail transport, canal, as well as electrical transmission lines, oil and gas pipelines. In the case of an easement, it may revert to its original owners if the facility is abandoned. This American English term is also used to denote the land itself. A right of way is granted or reserved over the land for transportation purposes, usually for private access to private land and, historically for a highway, public footpath, rail transport, canal, as well as electrical transmission lines, oil and gas pipelines.Henry Campbell Black: ''Right-of-way.''

Natural Resources Wales
Natural Resources Wales ( cy, Cyfoeth Naturiol Cymru) is a Welsh Government sponsored body, which became operational from 1 April 2013, when it took over the management of the natural resources of Wales. It was formed from a merger of the Countryside Council for Wales, Environment Agency Wales, and the Forestry Commission Wales, and also assumed some other roles formerly performed by the Welsh Government. Roles and responsibilities Purpose NRW's purpose is to "pursue sustainable management of natural resources” and “apply the principles of sustainable management of natural resources” as stated in the Environment (Wales) Act 2016. Remit NRW receives a Remit Letter at the start of each financial year setting out what the Welsh Government wants it to achieve during that year. Its main responsibilities are: * Adviser: principal adviser to Welsh Government, and adviser to industry and the wider public and voluntary sector, and communicator about issues relating to the envi ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Coal Measures
In lithostratigraphy, the coal measures are the coal-bearing part of the Upper Carboniferous System. In the United Kingdom, the Coal Measures Group consists of the Upper Coal Measures Formation, the Middle Coal Measures Formation and the Lower Coal Measures Formation. The group records the deposition of fluvio-deltaic sediments which consists mainly of clastic rocks (claystones, shales, siltstones, sandstones, conglomerates) interstratified with the beds of coal. In most places, the coal measures are underlain by coarser clastic sequences known as Millstone Grit, of Namurian age. The top of the coal measures may be marked by an unconformity, the overlying rocks being Permian or later in age. In some parts of Britain, however, the coal measures grade up into mainly coal-barren red beds of late Westphalian and possibly Stephanian age. Within the Pennine Basin these barren measures are now referred to as the Warwickshire Group, from the district where they achieve their thickest d ...
