Bwlch Y Ddwyallt
Bwlch y Ddwyallt is the name commonly applied to the high point of the plateau of Gwaun Cerrig Llwydion in the eastern part of the Brecon Beacons in south Wales. It is a top of Waun Rydd. The plateau reaches its highest point of 754m above sea level on its northern rim overlooking the head of Cwm Cwareli. The name is an odd one to apply to a peak since the Welsh word 'bwlch' generally signifies a col or pass between mountains. Geology The plateau is formed from the hard-wearing sandstones of the Plateau Beds Formation of the Old Red Sandstone laid down during the Devonian period. These beds directly overlie the sandstones of the Brownstones Formation, also of Devonian age, which form the bulk of the hill. The cliffs below Bwlch y Ddwyallt shows signs of having been glaciated during the ice ages as do those beneath Graig Fan Las on the eastern edge of the plateau.

Waun Rydd
Waun Rydd is a mountain in the Brecon Beacons National Park, in southern Powys, Wales. Its height is 769 m (2,523 ft) and it tops a large boggy plateau rising to the east of Pen y Fan.Nuttall, John & Anne (1999). The Mountains of England & Wales - Volume 1: Wales (2nd edition ed.). Milnthorpe, Cumbria: Cicerone. . The hill takes the form of a plateau with sharp rims on several sides. To the northeast is Craig Pwllfa overlooking Cwm Banw whilst Craig y Fan looks east over Cwm Tarthwynni. To the south is the edge known as Cwar y Gigfran which translates into English as 'quarry of the crow'. It marks the top of a large landslipped area extending to the stream of Blaen y Glyn below. Several ridges extend north and east from the plateau. That known as Gist Wen runs north-northeast to the subsidiary top of Bryn (561m above sea level). The short ridges of Cefn Bach and Cefn Edmwnt run northeast whilst that of Twyn Du extends eastwards towards Talybont Reservoir Tal ...

Nuttall (hill)
This is a list of Nuttall mountains in England and Wales by height. Nuttalls are defined as peaks above in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above ; a mix of imperial and metric thresholds. The Nuttall classification was suggested by Anne and John Nuttall in their 1990 two–volume book, "The Mountains of England and Wales". The list was updated with subsequent revised editions by the Nuttalls. Because of the prominence threshold of only , the list is subject to ongoing revisions. In response, Alan Dawson introduced the Hewitts, with a higher prominence threshold of . This was the prominence threshold that the UIAA set down in 1994 for an "independent" peak. In 2010, Dawson replaced his Hewitts with the fully "metric" Simms, consisting of a height threshold of , and a prominence threshold of . However, both the Nuttall and Hewitt classifications have become popular with peak baggers, and both remain in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welsh Language
Welsh ( or ) is a Celtic language family, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Both the Welsh and English languages are ''de jure'' official languages of the Welsh Parliament, the Senedd. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 17.8% (538,300 people) and nearly three quarters of the population in Wales said they had no Welsh language skills. Other estimates suggest that 29.7% (899,500) of people aged three or older in Wales could speak Welsh in June 2022. Almost half of all Welsh speakers consider themselves fluent Welsh speakers ...

Powys
Powys (; ) is a Local government in Wales#Principal areas, county and Preserved counties of Wales, preserved county in Wales. It is named after the Kingdom of Powys which was a Welsh succession of states, successor state, petty kingdom and principality that emerged during the Middle Ages following the end of Roman rule in Britain. Geography Powys covers the historic counties of Montgomeryshire and Radnorshire, most of Brecknockshire, and part of Denbighshire (historic), historic Denbighshire. With an area of about , it is now the largest administrative area in Wales by land and area (Dyfed was until 1996 before several Preserved counties of Wales, former counties created by the Local Government Act 1972 were abolished). It is bounded to the north by Gwynedd, Denbighshire and Wrexham County Borough; to the west by Ceredigion and Carmarthenshire; to the east by Shropshire and Herefordshire; and to the south by Rhondda Cynon Taf, Merthyr Tydfil County Borough, Caerphilly County Bor ...

Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

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).

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.

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 ...

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 before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
