Foel Fraith
Foel Fraith is a hill in the Black Mountain (range), Black Mountain in the county of Carmarthenshire, southwest Wales. It lies within the Brecon Beacons National Park and Fforest Fawr Geopark. Its plateau-like summit attains a height of above sea level. To the north the subsidiary summit of Cefn y Cylchau reaches , and to the southeast is the subsidiary summit of Carn Fadog or Cefn Carn Fadog, which reaches a height of . Geology The hill has a split personality with its northern slopes dominated by the succession of Carboniferous Limestone rocks and its southern slopes by the Twrch Sandstone (formerly known as the 'Basal Grit') of the overlying Marros Group, but also dating from the Carboniferous period. In common with the Geology of South Wales, regional trend the rock strata dip moderately to the south though locally the beds overlying the limestone have foundered as this soluble rock has dissolved away over millennia. There is an extensive area of shakeholes across the ent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fan Fraith
Fan Fraith is a top of Fan Gyhirych in the Fforest Fawr section of the Brecon Beacons National Park in the county of Powys, south Wales. Its summit is at a height of 2192 feet or 668 m. It lies within Fforest Fawr Geopark. Geology The bulk of the hill is formed from sandstones and mudstones of the Brownstones Formation of the Old Red Sandstone laid down during the Devonian period. Sandstones of the overlying Plateau Beds Formation occur in the summit area as do beds of the Grey Grits Formation - both are assigned to the upper Devonian. The Plateau Beds sandstones occur across the whole southern aspect of the mountain and are often present as boulder fields,a result of periglacial activity. Several geological fault (geology), faults affect these rocks, the most significant of which is the northeast-southwest aligned Swansea Fault, a part of the Cribarth Disturbance.British Geological Survey 1:50,000 map sheet 231 'Merthyr Tydfil' & accompanying memoir Access The hill is entirely ...

Fforest Fawr Geopark
Fforest Fawr Geopark is a Geopark in the Brecon Beacons National Park, south Wales. It is the first designated Geopark in Wales having gained membership of both the European Geoparks Network and the UNESCO-assisted Global Network of National Geoparks in October 2005. The Geopark aims to promote and support sustainable tourism and other opportunities to improve the economy of the area whilst safeguarding the natural environment. Its aims largely coincide with the statutory duties and purpose of the National Park within which it sits. History of designation An initial application to the European Geoparks Network (EGN) made for a more geographically restricted Geopark based on the upper Swansea Valley was turned down in 2003 but the present area which extends to was accepted by the EGN at their meeting in October 2005. A Geopark Development Officer was appointed in January 2007 whilst the National Park Authority also employs an education officer part of whose time is dedicate ...

Llangadog
Llangadog () is a village and community located in Carmarthenshire, Wales, which also includes the villages of Bethlehem and Capel Gwynfe. A notable local landscape feature is Y Garn Goch with two Iron Age hill forts.The Welsh Academy Encyclopedia of Wales. Cardiff: University of Wales Press 2008. Llangadog was the administrative centre of the commote of Perfedd and had a castle, destroyed in 1204. Although the borough declined in the Middle Ages, Llangadog retained its market, which was frequented by drovers into the 19th century. The railway station on the Heart of Wales Line provides regular train services via Transport for Wales Rail. The station had a siding for accessing the Co-op Wholesale Society creamery, allowing milk trains to access the site. After railway access was ceased in the late 1970s, the creamery continued to operate until 2005, when it closed with the loss of 200 jobs. The site has since been redeveloped as a pet food factory.

Abergavenny
Abergavenny (; cy, Y Fenni , archaically ''Abergafenni'' meaning "mouth of the River Gavenny") is a market town and Community (Wales), community in Monmouthshire, Wales. Abergavenny is promoted as a ''Gateway to Wales''; it is approximately from the England–Wales border, border with England and is located where the A40 road, A40 trunk road and the A465 road, A465 Heads of the Valleys road meet. Originally the site of a Castra, Roman fort, Gobannium, it became a Middle Ages, medieval Defensive wall, walled town within the Welsh Marches. The town contains the remains of a medieval stone castle built soon after the Norman invasion of Wales, Norman conquest of Wales. Abergavenny is situated at the confluence of the River Usk and a tributary stream, the Gavenny. It is almost entirely surrounded by mountains and hills: the Blorenge (), the Sugar Loaf Mountain, Wales, Sugar Loaf (), Ysgyryd Fawr (Great Skirrid), Ysgyryd Fach (Little Skirrid), Deri, Rholben and Mynydd Llanwenarth, ...

Beacons Way
The Beacons Way (Welsh: Ffordd y Bannau) is a waymarked long distance footpath in the Brecon Beacons National Park, Wales. It is a linear route which runs for east to west through the National Park, and passes many of the most important landmarks and mountain peaks in the mountain range. It also includes a few of the towns in the park as well as popular attractions such as Carreg Cennen Castle near Llandeilo at the western end of the path. The route Black Mountains The Beacons Way as originally conceived started in Abergavenny, Monmouthshire, at the eastern end of the National Park and headed northeast to Ysgyryd Fawr. It was later changed so that it started on the B4521 road immediately south of the hill at coordinates though the connection with Abergavenny has since been reinstated, albeit on a slightly different route: it now starts at Abergavenny railway station. Beyond Ysgyryd Fawr the route drops down to Llanfihangel Crucorney, passing The Skirrid Mountain Inn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shakehole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. A ''sink'' or ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of South Wales
South Wales is an area with many features of outstanding interest to geologists, who have for long used the area for University field trips. This varied and accessible region has provided a written record of geological interest that dates to the 12th century, when Giraldus Cambrensis noted pyritous shales near Newport. Some of the first published representations of fossils were of fossil plants from coal measures near Neath (Gibson late 17th century). The British geologists Adam Sedgwick and Roderick Murchison did fundamentally important work in South Wales on Old Red Sandstone and the underlying rocks. The first volume of memoirs (1846) published by the Geological Survey contained a conspectus of the geology of South Wales that set a template for all future work. Significant discoveries continue to be made. For instance, in Carmarthenshire, in the late 1970s, John Cope detected a small area of Precambrian and Cambrian rocks. Other parts of South Wales, however, have not seen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous Period
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lineage ...

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 th ...

Carboniferous Limestone
Carboniferous Limestone is a collective term for the succession of limestones occurring widely throughout Great Britain and Ireland that were deposited during the Dinantian Epoch of the Carboniferous Period. These rocks formed between 363 and 325 million years ago. Within England and Wales, the entire limestone succession, which includes subordinate mudstones and some thin sandstones, is known as the Carboniferous Limestone Supergroup. Depositional basins Within Great Britain the suite of rocks known traditionally as the Carboniferous Limestone Series was deposited as marine sediments in three distinct ‘provinces’ separated by contemporary landmasses. One of these landmasses was the Wales-London-Brabant Massif, an east–west aligned belt of land stretching through central Wales and the English Midlands to East Anglia and on into Belgium. The limestones deposited to its south form a distinct South Wales-Mendip province which extends from Pembrokeshire in the west ...

Brecon Beacons National Park
The Brecon Beacons National Park ( cy, Parc Cenedlaethol Bannau Brycheiniog) is one of three national parks in Wales, and is centred on the Brecon Beacons range of hills in southern Wales. It includes the Black Mountain ( cy, Y Mynydd Du) in the west, Fforest Fawr (translates as 'great forest') and the Brecon Beacons in the centre and the Black Mountains ( cy, Y Mynydd Du or Mynyddoedd Duon) in the east. Description The Brecon Beacons National Park was established in 1957, the last of the three Welsh parks designated after Snowdonia in 1951 and the Pembrokeshire Coast in 1952. It stretches from Llandeilo in the west to Hay-on-Wye in the northeast and Pontypool in the southeast, covering and encompassing four main regions – the Black Mountain in the west, reaching 802 metres (2631 feet) at Fan Brycheiniog, Fforest Fawr and the Brecon Beacons in the centre, including the highest summit in the park and in South Wales at Pen y Fan 886 metres (2,907 feet) and the confusingly ...

Fforest Fawr
Fforest Fawr is an extensive upland area in the county of Powys, Wales. Formerly known as the Great Forest of Brecknock in English, it was a royal hunting area for several centuries but is now used primarily for sheep grazing, forestry, water catchment and recreation. It lies within the Brecon Beacons National Park. Extent The area extends from the edge of the Black Mountain in the west eastwards to the A470 Brecon to Merthyr Tydfil road, just west of the Brecon Beacons themselves. It includes the peaks of Fan Fawr (734 m), Fan Frynych (629 m), Craig Cerrig-gleisiad (629 m), Fan Llia (632 m), Fan Nedd (663 m), Fan Gyhirych (725 m), Fan Bwlch Chwyth (603 m) and Cefn Cul (562 m). Traditionally Fforest Fawr also included the peaks of Fan Hir and Fan Brycheiniog, although the modern recreational use of the name tends to be restricted to the area east of the Black Mountain of which they form a part.
