Dylife Gorge
The Dylife Gorge, located near Dylife, Powys, Mid Wales, was carved by the action (and aftermath) of the last Ice age. It is headed by the Ffrwd Fawr Waterfall. Before the last Ice age, the Afon Twymyn, River Twymyn did not flow through the valley. When the valley was filled by a glacier, the ice ground out a U-shaped glaciated valley. When the glacier that filled the valley melted the Twymyn started to run down the wide channel left behind and the fast flowing river further eroded the valley, cutting the V-shaped Canyon, gorge as seen today. The long-distance footpath Glyndŵr's Way (Welsh: ''Llwybr Glyndŵr'') passes nearby.

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 ...

Montgomeryshire (UK Parliament Constituency)
Montgomeryshire ( cy, Sir Drefaldwyn) is a constituency represented in the House of Commons of the Parliament of the United Kingdom. Created in 1542, it elects one Member of Parliament (MP), traditionally known as the knight of the shire, by the first-past-the-post system of election. The Montgomeryshire Senedd constituency was created with the same boundaries in 1999 (as an Assembly constituency). Boundaries The seat is based on the ancient county of Montgomeryshire, in the principal area of Powys. One of Britain's most rural and isolated constituencies, Montgomeryshire elected Liberal or Liberal-affiliated candidates from 1880, until a Conservative victory in the 1979 general election. In the 1983 general election it was the only seat in England and Wales where a sitting Conservative MP was unseated, while nationally the party's seat majority increased. However, in 2010, the Conservatives won and held the seat in 2015 and 2017, with an increased majority. The seat was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dylife
Dylife is a former mining settlement in Powys, Wales, located at the head of Afon Twymyn in the Cambrian Mountains, one mile west of the road between Llanidloes and Llanbrynmair ( B4518). It is in the historic county of Montgomeryshire. The nearby lead mines intermittently sustained mining communities from Roman times until the early 20th century. During the late 19th century, as mining declined after the 1860s so did Dylife's population. The remaining buildings are two former chapels converted into homes and the Star Inn. Mining Lead mining around Dylife took place in Roman times (there is a Roman fort on nearby Penycrocbren) and recommenced in the 17th century on a small scale until the early 19th century. In 1809, the two managers, Hugh Williams and John Pughe, started to negotiate for the lease which they obtained in 1815. The two men operated the mines until the 1850s, although not harmoniously. The mines were expanded with new shafts and machinery was brought in to assi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid Wales
Mid Wales ( cy, Canolbarth Cymru or simply ''Y Canolbarth'', meaning "the midlands") or Central Wales refers to a region of Wales, encompassing its midlands, in-between North Wales and South Wales. The Mid Wales Regional Committee of the Senedd covered the unitary authority areas of Ceredigion and Powys and the area of Gwynedd that had previously been the district of Meirionnydd. A similar definition is used by the BBC. The Wales Spatial Plan defines a region known as "Central Wales" which covers Ceredigion and Powys. Mid Wales is dominated by the Cambrian Mountains, including the Green Desert of Wales. The region is sparsely populated, with an economy dependent on farming and small businesses.

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 Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''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, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Valley
A valley is an elongated low area often running between Hill, hills or Mountain, mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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 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 every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glyndŵr's Way
Glyndŵr's Way ( cy, Llwybr Glyndŵr) is a long-distance footpath in mid Wales. It runs for in an extended loop through Powys between Knighton and Welshpool, and anchored on Machynlleth to the west. History Its name derives from the early 15th century Welsh prince and folk hero Owain Glyndŵr, whose parliament sat in Machynlleth in 1404. Glyndŵr's Way was granted National Trail status in 2000 to mark the beginning of the third millennium and the 600th anniversary of an ill-fated but long-running and culturally significant rebellion in 1400. Route The footpath officially begins in Knighton, on the English border, where it links with Offa's Dyke Path. Running in roughly a horseshoe shape, it passes small market towns such as Llanidloes and quiet villages including Abbeycwmhir and Llanbadarn Fynydd, traversing central Mid Wales to Machynlleth near the Dyfi estuary and returning across Wales via Llanbrynmair, Llangadfan and Lake Vyrnwy and the valley of the River Vyrnwy ...

Geology Of The United Kingdom
The geology of Great Britain is renowned for its diversity. As a result of its eventful geological history, Great Britain shows a rich variety of landscapes across the constituent countries of England, Wales and Scotland. Rocks of almost all geological ages are represented at outcrop, from the Archaean onwards. Overview Seismographical research shows that the crust of the Earth below Great Britain is from 27 to 35 km (17 to 22 miles) thick. The oldest surface rocks are found in north west Scotland and are more than half as old as the planet. These rocks are thought to underlie much of Great Britain (although boreholes have only penetrated the first few kilometres), but next appear extensively at the surface in Brittany and the Channel Islands. The youngest rocks are found in south east England. Bedrock and past volcanism The bedrock geology consists of a complex mix of generally older metamorphic rocks overlain by varying sequences of sedimentary rocks into both of ...
