Black Mountain (range), Wales
The Black Mountain () is a mountain range in South, Mid and West Wales, straddling the county boundary between Carmarthenshire and Powys, and forming the westernmost range of the Brecon Beacons National Park. Its highest point is Fan Brycheiniog at 802 metres or 2,631 ft. The Black Mountain also forms a part of the Fforest Fawr Geopark. Name The Black Mountain should not be confused with the Black Mountains in the east of the National Park, nor with a summit in the Black Mountains that is confusingly also called Black Mountain. In his description of a ''Blak Montayne'', the antiquarian John Leland refers to a massif extending between Carmarthen and Monmouth i.e. what is now considered to be the Brecon Beacons in the wider modern sense of that term, thus also including the Black Mountains and the intervening high ground of Fforest Fawr. The term " Carmarthen Fans" (''Bannau Sir Gâr'' in Welsh) is sometimes used inaccurately to describe the whole of this massif, ...

Welsh Language
Welsh ( or ) is a Celtic languages, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales by about 18% of the population, by some in England, and in (the Welsh colony in Chubut Province, Argentina). It is spoken by smaller numbers of people in Canada and the United States descended from Welsh immigrants, within their households (especially in Nova Scotia). 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. Welsh and English are ''de jure'' official languages of the Senedd (the Welsh parliament), with Welsh being the only ''de jure'' official language in any part of the United Kingdom, with English being merely ''de facto'' official. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 538,300 ( ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages, and greenhouse periods during which there are no glaciers on the planet. Earth is currently in the ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, the term ''ice age'' is defined by the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, the current Holocene epoch is an interglacial period of an ice age. The accumulation of anthropogenic greenhouse gases is projected to delay the next glacial period.

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on ever ...

Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. Due to the similarity, the term '' scarp'' may mistakenly be incorrectly used interchangeably with ''escarpment.'' ''Escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a transition from one seri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twrch Sandstone
The Marros Group is the name given to a suite of rocks of Namurian age laid down during the Carboniferous period (geology), Period in South Wales. These rocks were formerly known as the Millstone Grit, Millstone Grit Series but are now distinguished from the similar but geographically separate rock sequences of the Pennine Range, Pennines and Peak District of northern England and northeast Wales by this new name. Stratigraphy The Group comprises a thick rock unit, 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’ an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Red Sandstone
Old Red Sandstone, abbreviated ORS, 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 eastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the paleocontinent of Euramerica (Laurussia). In Britain it is a lithostratigraphic unit (a sequence of rock strata) to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology. The presence of ''Old'' in the name is to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain. Sedimentology The Old Red Sandstone describes a group of sedimentary rocks deposited in a variety of environments in the late Silurian, through the Devonian and into the earliest part of the Carboniferous. The body of rock, or facies, is dominated by terrigenous deposits and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a period (geology), geologic period and system (stratigraphy), system of the Paleozoic era (geology), era during the Phanerozoic eon (geology), eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Megaannum, Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of history of life#Colonization of land, life on land occurred during the Devonian, as free-spore, sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaf, leaves and true roots, and by the end of the period the first seed-bearing plants (Pteridospermatophyta, pteridospermatophyt ...

Sennybridge
Sennybridge () is a village in Powys, Wales, in the historic county of Brecknockshire, situated some from Cardiff and from Swansea. It lies west of Brecon on the A40 trunk road to Llandovery, at the point where the Afon Senni flows into the Usk. It is in the community of Maescar. Economy One factor that influenced the growth of Sennybridge was the Neath and Brecon Railway, which opened a station in the adjoining village of Defynnog in 1867. The promoter and contractor of the railway, John Dickson, also made a start on constructing a railway north from Sennybridge that would have linked the Neath and Brecon Railway to the Central Wales Line at Llangammarch Wells but work was suspended on his bankruptcy in 1867 and never resumed. The partially completed earthworks can still be seen in the countryside north of Sennybridge. In an earlier era, in about 1821 the Brecon Forest Tramroad started construction. The northern terminus of the route from the Swansea Valley (vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It was originally known as Cross Inn, named after an inn that was located at a location where a number of roads converged. During the nineteenth century, as a result of the growth of both the tinplate and anthracite coal trades, a village grew around the Cross Inn (which later became known as Ammanford Square). As the settlement expanded, prominent residents came to the view that its name shou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
