Cribyn (mountain)
Cribyn () is a mountain in the Brecon Beacons (Bannau Brycheiniog) with an elevation of 2608 feet (or 795 metres), about 300 feet lower than the neighbouring peaks of Pen y Fan and Corn Du. It is a prominent peak in the long and impressive escarpment facing north and running roughly east–west of the central section of the Brecon Beacons. The summit lies on a ridge stretching from Talybont Reservoir in the east, to the A470 road. The ridge line to the west connects Cribyn with the peak of Pen y Fan. To the east, the ridge line descends to Bwlch ar y Fan, a mountain pass, col crossed by an ancient trail sometimes known as 'The Gap Road' before ascending again to the peak of Fan y Big. Geology In common with other peaks of the Brecon Beacons, the upper slopes of Cribyn are formed from sandstones of the Brownstones Formation of the Old Red Sandstone laid down during the Devonian period. The lower slopes of the hill are formed from sandstones and mudstones of the unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pen Y Fan
Pen y Fan () is the highest peak in South Wales, situated in Brecon Beacons National Park (Bannau Brycheiniog). At above sea-level, it is also the highest British peak south of Cadair Idris in Snowdonia. It is the highest point (List of counties of England and Wales in 1964 by highest point, county top) of the historic county of Brecknockshire (though in modern administrative terms, it now lies within the unitary council area of Powys). The twin summits of Pen y Fan and Corn Du at were formerly referred to as Cadair Arthur or 'Arthur's Seat'. The mountain and surrounding area are owned by the National Trust for Places of Historic Interest or Natural Beauty, National Trust whose work parties attempt to combat the erosion caused by the popularity of this peak with walkers. The mountain is used by the Ministry of Defence (United Kingdom), military as part of the United Kingdom Special Forces Selection, selection process of the United Kingdom, UK's United Kingdom Special Forces, S ...

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] |
Brecon
Brecon (; ; ), archaically known as Brecknock, is a market town in Powys, mid Wales. In 1841, it had a population of 5,701. The population in 2001 was 7,901, increasing to 8,250 at the 2011 census. Historically it was the county town of Brecknockshire (Breconshire); although its role as such was eclipsed with the formation of the County of Powys, it remains an important local centre. Brecon is the third-largest town in Powys, after Newtown, Powys, Newtown and Ystradgynlais. It lies north of the Brecon Beacons mountain range, but is just within the Brecon Beacons National Park. History Early history The Welsh language, Welsh name, Aberhonddu, means "mouth of the Honddu". It is derived from the River Honddu (Powys), River Honddu, which meets the River Usk near the town centre, a short distance away from the River Tarell which enters the Usk a few hundred metres upstream. After the Dark Ages (historiography), Dark Ages the original Welsh name of the kingdom in whose territory Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mynydd Epynt
Mynydd Epynt () is an upland region of Mid Wales, within the county of Powys. It is bounded on the south by the upper stretch of the Usk Valley, on the north by the Irfon Valley, and on the east by the Wye Valley. Its western boundary is less distinct but lies east of the A483 Llandovery to Llanwrtyd Wells road. The area is an extensive plateau lying between 400 and 450m, drained by several southward-flowing rivers that empty into the River Usk; these include (from west to east) the Cilieni, the Nant Bran, the Afon Ysgir (with its two headwaters, the Ysgir Fechan and Ysgir Fawr) and the Afon Honddu. The Duhonw drains north-eastward into the River Wye. The highest point is a marilyn (having topographic prominence of at least 150m) of 478m. Since 1940, Mynydd Epynt has formed part of the Sennybridge Training Area, the largest military training zone in Wales. Etymology The name of the area is often given as ''Mynydd Eppynt'' or ''Eppynt'' in historical sources and it ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Army
The British Army is the principal Army, land warfare force of the United Kingdom. the British Army comprises 73,847 regular full-time personnel, 4,127 Brigade of Gurkhas, Gurkhas, 25,742 Army Reserve (United Kingdom), volunteer reserve personnel and 4,697 "other personnel", for a total of 108,413. The British Army traces back to 1707 and the Acts of Union 1707, formation of the united Kingdom of Great Britain which joined the Kingdoms of Kingdom of England, England and Kingdom of Scotland, Scotland into a Political union, single state and, with that, united the English Army and the Scots Army as the British Army. The Parliament of England, English Bill of Rights 1689 and Convention of the Estates, Scottish Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Members of the British Army swear allegiance to the Charles III, monarch as their commander-in-chief. The army is administered by the Ministry of Defence (United Kingd ...

National Trust
The National Trust () is a heritage and nature conservation charity and membership organisation in England, Wales and Northern Ireland. The Trust was founded in 1895 by Octavia Hill, Sir Robert Hunter and Hardwicke Rawnsley to "promote the permanent preservation for the benefit of the Nation of lands and tenements (including buildings) of beauty or historic interest". It has since been given statutory powers, starting with the National Trust Act 1907. Historically, the Trust acquired land by gift and sometimes by public subscription and appeal, but after World War II the loss of country houses resulted in many such properties being acquired either by gift from the former owners or through the National Land Fund. One of the largest landowners in the United Kingdom, the Trust owns almost of land and of coast. Its properties include more than 500 historic houses, castles, archaeological and industrial monuments, gardens, parks, and nature reserves. Most properties are open ...

Freedom To Roam
The freedom to roam, or everyone's right, every person's right or everyman's right, is the general public's right to access certain public or privately owned land, lakes, and rivers for recreation and exercise. The right is sometimes called the right of public access to the wilderness or the right to roam. In Austria, Belarus, Estonia, Finland, Iceland, Latvia, Lithuania, Norway, Scotland, Sweden, Switzerland and the Czech Republic, the freedom to roam takes the form of general public rights which are sometimes codified in law. The access is ancient in parts of Northern Europe and has been regarded as sufficiently fundamental that it was not formalised in law until modern times. However, the right usually does not include any substantial economic exploitation, such as hunting or logging, or disruptive activities, such as making fires and driving offroad vehicles. In countries without such general rights, there may be a network of rights of way, or some nature reserves with foot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cribyn Seen From Cefn Cwm Llwch - Geograph
Cribyn is a small village in Ceredigion, Wales, about 7 miles (11 km) north of Lampeter and with the villages of Troed y Rhiw, Mydroilyn and Dihewyd to the north. History and amenities Once a thriving community with two pubs, a garage and a post office, it is now largely reduced to a dormitory town or commuter village for Lampeter. The primary school in the village, founded by local hero Gwilym Butler-Wilkins, has maintained its status as primarily Welsh speaking since its establishment in 1876. Cribyn has one of the few Unitarian chapels in Ceredigion, which was established in 1790 by Dafydd Davis Castellhywel and Evan Davies, Cwmbedw. There was an old cottage next to the Nonconformist chapel which was older than the chapel, and a school was held here for many years until the primary school was founded. Four parishes meet in Cribyn, and most parishioners went to the parish church in Llanfihangel Ystrad until the present church was established at the end of the 19t ...

Glacial Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by Solvation, dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and Rock (geology), 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 are those 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 language, French , which in turn is derived from the Savoyard dialect, Savoyard Italian ('mound of e ...

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.

Rock Strata
In geology and related fields, a stratum (: strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.
