Waun Lefrith
Waun Lefrith is a top of Picws Du and is also the westernmost of the Carmarthen Fans or Bannau Sir Gaer, a group of peaks within the Black Mountain (Y Mynydd Du) of the Brecon Beacons National Park (Parc Cenedlaethol Bannau Brycheiniog). It lies within Carmarthenshire, Wales. The summit plateau of the mountain reaches a height of 2221 feet above sea level. Picws Du and Fan Foel are the other, higher summits of the Bannau Sir Gaer / Carmarthen Fans. The glacial lake of Llyn y Fan Fach dominates the panorama to the north of the peak. Beyond the lake to the north lies the Usk Reservoir and then the Cambrian Mountains on the horizon. Swansea Bay and the Bristol Channel are visible to the south across the undulating dip slope of the mountain. The Tywi valley lies to the west, with Llandovery and Llandeilo as important market towns nearest to the hills. Geology Waun Lefrith is formed from the sandstones and mudstones of the Brownstones Formation of the Old Red Sandstone laid dow ...

Picws Du
Picws Du is the second highest peak of the Carmarthen Fans (or, in Welsh ''Bannau Sir Gâr'') in the Carmarthenshire section of the Black Mountain in the west of the Brecon Beacons National Park in south Wales. The highest peak is Fan Foel immediately next along the ridge and it is a subsidiary summit of Fan Brycheiniog. Picws Du falls within Fforest Fawr Geopark and its prominent summit is marked by a large Bronze Age round barrow at a height of 2457 feet above sea level. Waun Lefrith is the other, lower summit of the Bannau Sir Gâr / Carmarthen Fans situated to the west. The peak overlooks the glacial lake of Llyn y Fan Fach in the cwm below. As the peak sits on the edge of the escarpment on a ridge which juts out into the valley below, the views from the summit are panoramic and extensive. The views to the north are especially impressive when the weather is clear, looking towards the Cambrian Mountains, Mynydd Epynt and Brecon. Swansea and the Bristol Channel can just be s ...

Llanddeusant, Carmarthenshire
Llanddeusant () is a very sparsely populated community in the Black Mountain (range) of the Brecon Beacons National Park in Carmarthenshire, Wales. It is about 5 miles southeast of Llangadog. Llanddeusant lies within the Llansadwrn & Llangadog / Myddfai & Llanddeusant ward, which had a population of 2,412 at census 2001. The boundaries were changed and most of the population was shown under the Llangadog community. The remaining population at the 2011 census was 220 only. The name, meaning "church of two saints", is supposed to originate from the fact that Teilo and Saint David are believed to have met there. The 'Old Red Lion Inn' is now a Youth hostel. The community includes the hamlet of Twynllanan. Setting The village lies below the prominent Black Mountain (range) escarpment and the glacial lake of Llyn y Fan Fach. The lake is the setting of a famous folk tale known as The Lady of the Lake. Beacons way A low level alternative of the footpath the Beacons Way runs by Llandde ...

Llyn Y Fan Fach (1323880314)
Llyn y Fan Fach (Welsh meaning "little lake (near) the peak") is a lake of approximately on the northern margin of the Black Mountain in Carmarthenshire, South Wales and lying within the Brecon Beacons National Park. The lake lies at an altitude of approximately , immediately to the north of the ridge of the Carmarthen Fans. It is the smaller of two lakes within this mountain massif: the slightly larger Llyn y Fan Fawr is about to the east. Geology The lake is overlooked by several prominent mountain peaks, especially Picws Du and Waun Lefrith. Waun Lefrith is formed from the sandstones and mudstones of the Brownstones Formation of the Old Red Sandstone laid down during the Devonian period. Its southern slopes are formed from the hard-wearing sandstones of the overlying Plateau Beds Formation which are of upper/late Devonian age. It is those rocks which form vertical crags along the top edge of the scarp. The northern face of Waun Lefrith was home to a glacier during the ice ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

River Tawe
The River Tawe (; cy, Afon Tawe ) is a long river in South Wales. Its headwaters flow initially east from its source below Llyn y Fan Fawr south of Moel Feity in the Black Mountains, the westernmost range of the Brecon Beacons National Park, before the river turns south and then southwest to its estuary at Swansea. Its main tributaries are the right bank Upper and Lower Clydach Rivers and the Afon Twrch. The total area of the catchment is some . The Tawe passes through a number of towns and villages including Ystradgynlais, Ystalyfera, Pontardawe, and Clydach and meets the sea at Swansea Bay below Swansea. The Tawe Valley ( in Welsh) is more commonly known as the Swansea Valley. Ownership of the riverbed was granted to the Duke of Beaufort in the 17th century by Charles II resulting in exclusive mineral and fishing rights, which is extended as far as requiring permission and payment for bridges which are built over it. This was last exercised in 2008 when Swansea Cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afon Twrch
The Afon Twrch is a river which rises in the Black Mountain in south Wales. It forms the boundary between the counties of Brecknockshire (currently administered as part of the unitary authority of Powys) and Carmarthenshire and, downstream of Ystradowen, between Brecknockshire and Glamorgan (and unitary authorities of Powys and Neath Port Talbot). Name The name derives from Welsh afon / 'river' and twrch / 'boar'. In common with other rivers sharing the same name, it is believed to refer to the burrowing or snouting action of the waters of the river. The river has also been associated with the legend of Twrch Trwyth. Geography The headwaters arise on the southern slopes of Bannau Sir Gaer ( Carmarthen Fans) and Fan Brycheiniog and are soon joined by the waters of the Twrch Fechan. The river flows south-west and then south and finally south-east for about 14 km / 9 miles to its confluence with the River Tawe at Ystalyfera. Significant tributaries include the Nant Gwys ...

Afon Sawdde
The Afon Sawdde is a river in the county of Carmarthenshire, Wales. For most of its course it flows through the Brecon Beacons National Park and Fforest Fawr Geopark. Llyn y Fan Fach The river rises on the northern slopes of the Black Mountain and flows north, then west, then northwest for a total of some 18 km to its confluence with the River Towy near Llangadog. The source of the river is Llyn y Fan Fach, a lake of glacial origin sitting in a deep cwm beneath Bannau Sir Gaer.

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

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 ...
