Fan Fawr
Fan Fawr ( Welsh 'great peak') is a mountain in the Fforest Fawr section of the Brecon Beacons National Park, in Powys, Wales and over 734 m (2,408 ft) high. The summit overlooks the steep eastern face and is marked by a cairn. Unusually, the trig point on this hill does not sit at the summit but 600 m to the south-west on a subsidiary spur. The hill is drained to the west by streams flowing into the Afon Dringarth and to the east by streams draining into the Taf Fawr. The Dringarth is dammed to the west to form Ystradfellte Reservoir as is the Taf Fawr east of the hill to form Beacons Reservoir. To the north-east water flows into the Afon Tarell, a tributary of the River Usk whilst to the south the headwaters of the Afon y Waun conduct water to the Afon Hepste and eventually to the River Neath. Geology The hill is largely formed from sandstones of the Brownstones Formation of the Old Red Sandstone which were laid down during the Devonian period. On the ...

Fan Llia
Fan Llia is a subsidiary summit of Fan Fawr in the Fforest Fawr section of the Brecon Beacons National Park, Wales. In common with other peaks in the Fforest Fawr uplands it lies within the county of Powys. The hill has the form of a broad ridge aligned south-south-west to north-north-east peaking at an altitude of 632 m. It has a subsidiary top to the north which is known as Fan Dringarth and which attains a height of 617 m. Its broad northern ridge is eventually truncated by the cliffs of Craig Cwm-du. A number of features of archaeological interest are to be found on its flanks including several house platforms. Geology The hill is formed largely from sandstones of the Brownstones Formation of the Old Red Sandstone dating from the Devonian period. Its southernmost slopes (around Cefn Perfedd) are formed in Plateau Beds Formation sandstones and an area in the north-east is underlain by sandstones and mudstones of the Senni Beds Formation. Rock exposures are infrequent − ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afon Dringarth
The Afon Dringarth (or simply ''Tringarth'') is a river in Powys, Wales and wholly contained within the Brecon Beacons National Park. Its headwater streams drain the eastern slopes of Fan Dringarth (which is probably named after the river), the southern slopes of Craig Cerrig-gleisiad and the western slopes of Fan Fawr. The river flows south-southwest for about 6 km / 3.5 mi to its confluence with the Afon Llia one mile north of the village of Ystradfellte, continuing south as the Afon Mellte. The river may derive its name from the hill immediately to its west, Fan Dringarth. The Afon Dringarth flows across ground formed from the Old Red Sandstone laid down during the Devonian period. The presence of areas of glacial till reveals that the area was inundated by ice during the ice ages. The waters of the river were impounded by a dam during the early 20th century to form Ystradfellte Reservoir. External links Images of Afon Dringarth and area on Geograph website Refere ...

Marilyns Of Wales
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A470 Road
The A470 (also named the Cardiff to Glan Conwy Trunk Road) is a trunk road in Wales. It is the country's longest road at and links the capital Cardiff on the south coast to Llandudno on the north coast. While previously one had to navigate the narrow roads of Llanidloes and Dolgellau, both these market towns are now bypassed due to extensive road modernisation. The from Cardiff Bay to Merthyr Tydfil are mainly dual carriageway, but most of the route from north of Merthyr to Llandudno is single carriageway. Route National parks The road travels through two of the national parks of Wales: the Brecon Beacons, and Snowdonia National Park starting just south of Dinas Mawddwy. Cardiff Bay – Merthyr Tydfil The southernmost point of the route is in Cardiff Bay, outside the Wales Millennium Centre. It runs up Lloyd George Avenue (this was previously Collingdon Road, and the A470 previously ran along the parallel Bute Street), and continues along St. Mary Street in central Car ...

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 dedicated ...

Devonian Period
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 ...

Old Red Sandstone
The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica, Euramerica/Laurussia. In Britain it is a lithostratigraphy, lithostratigraphic unit (a sequence of rock strata) to which Stratigraphy, stratigraphers accord Geological unit#Lithostratigraphic units, supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain. Sedimentology The Old Red Sandstone describes a suite of sedimentary rocks deposited in a variety of environments during the Devonian ...

River Neath
River Neath ( cy, Afon Nedd) is a river in south Wales running south west from the point at which its headwaters arising in the Brecon Beacons National Park converge to its mouth at Baglan Bay below Briton Ferry on the east side of Swansea Bay. Course The rivers Nedd Fechan, Mellte and Hepste rise in south Powys on the southern slopes of Fforest Fawr. This headwater area is formed from Old Red Sandstone. Each then crosses a band of Carboniferous Limestone before traversing country formed by interlayered sandstones and shales traditionally referred to as the Millstone Grit. Within the limestone belt, short sections of each river flow underground, though that of the Hepste also flows at the surface during periods of particularly wet weather. The steep descent of these rivers towards the Vale of Neath, and also of the Afon Pyrddin and Afon Sychryd, tributaries of the Nedd Fechan and Afon Mellte respectively, involves the development of a number of waterfalls over resistant ban ...

Afon Hepste
The Afon Hepste is a river in Powys, Wales, though partly forming the county's border with Rhondda Cynon Taf. It runs wholly within the Brecon Beacons National Park. Its headwaters, the Afon y Waun, Nant y Cwrier and Nant Hepste Fechan, rise on the Old Red Sandstone dip-slopes of Fforest Fawr and combine to form the Afon Hepste near the farmstead of Hepste Fechan. It enters onto the Carboniferous Limestone outcrop near this point and sections of its course downstream remain dry in all but flood conditions as the flow disappears underground. The river flows over the Millstone Grit outcrop from some way beyond Hepste Bridge.British Geological Survey 1:50,000 map no 231 'Merthyr Tydfil' & accompanying memoir The Hepste plunges over a band of resistant gritstone to form Sgwd yr Eira (translated from Welsh as 'fall of snow'). A public footpath runs behind this fall, making it one of the most popular destinations in an area that has become known as Waterfall Country. One mile dow ...

River Usk
The River Usk (; cy, Afon Wysg) rises on the northern slopes of the Black Mountain (''y Mynydd Du''), Wales, in the westernmost part of the Brecon Beacons National Park. Initially forming the boundary between Carmarthenshire and Powys, it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course. Beyond the eponymous town of Usk it passes the Roman legionary fortress of Caerleon to flow through the heart of the city of Newport and into the Severn Estuary at Uskmouth beyond Newport near the Newport Wetlands. The river is about long. The Monmouthshire and Brecon Canal follows the Usk for most of the length of the canal. Etymology The name of the river derives from a Common Brittonic word meaning "abounding in fish" (or possibly "water"), this root also appears in other British river names such as Exe, Axe, Esk and other variants.

Afon Tarell
The Afon Tarell is a river in Powys, Wales, which rises to the west of the Brecon Beacons in Brecon Beacons National Park and flows north, then north-east, for into the River Usk. The river is followed for its entire length through Glyn Tarell (the Tarell valley) by the A470 road, passing by the hamlets of Libanus and Tai'r Bull and entering the Usk at Llanfaes on the southern edge of Brecon. The most significant tributary of the river is Nant Cwm Llwch, which enters the Tarell on its right bank between Tai'r Bull and Llanfaes. This secondary river emerges from the glacial lake of Llyn Cwm Llwch beneath Pen y Fan. The name may have its origins in the old Welsh language words ''tarddu'', "to bubble out", and ''tarddell'', "a spring or source". The Afon Tarell, in common with the Usk and its other tributaries, is designated as a special area of conservation for its three species of lamprey, twaite shad, European bullhead, Atlantic salmon and otter Otters are carnivorous ma ...
