Clwyd Limestone Group
The Clwyd Limestone Group is a stratigraphic unit (a defined sequence of rock layers) of Chadian to Brigantian age ( Lower Carboniferous) found in north Wales. It forms part of the Carboniferous Limestone Supergroup. Its most extensive outcrop is along the length of the Clwydian Range, immediately to the east of its crest, between Llandegla and Prestatyn. A further though more fragmented outcrop extends in an arc along the western margins of the Vale of Clwyd north from Rhyd-y-meudwy, west of Ruthin and then northwest to meet the coast at Llanddulas. It is prominently exposed at the Great Orme and Little Orme near Llandudno and again in three areas of eastern and southern Anglesey, together with a small area to the south of the Menai Strait between Bangor and Y Felinheli. The outcrop also extends southwards from Llandegla to form an impressive scarp at Creigiau Eglwyseg north of Llangollen and south again, to the west of Oswestry to Llanymynech Hill on the Powys/Shropsh ...

Group (stratigraphy)
In geology, a group is a lithostratigraphic unit consisting of a series of related formations that have been classified together to form a group. Formations are the fundamental unit of stratigraphy. Groups may sometimes be combined into supergroups. Groups are useful for showing relationships between formations, and they are also useful for small-scale mapping or for studying the stratigraphy of large regions. Geologists exploring a new area have sometimes defined groups when they believe the strata within the groups can be divided into formations during subsequent investigations of the area. It is possible for only some of the strata making up a group to be divided into formations. An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distinguished from its neighbor by its lithology, but all were deposited in the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vale Of Clwyd
The Vale of Clwyd ( cy, Dyffryn Clwyd) is a tract of low-lying ground in the county of Denbighshire in north-east Wales. The Vale extends south-southwestwards from the coast of the Irish Sea for some 20 miles (about 30 km) forming a triangle of low ground bounded on its eastern side by the well-defined scarp of the Clwydian Range and to the west by numerous low hills. The River Clwyd (Welsh: ) which rises within Clocaenog Forest, southwest of Denbigh, runs the full length of the vale. It is joined by the two major left bank tributaries of the River Clywedog (Welsh: ) and River Elwy (Welsh: ) and the smaller right bank tributary of the River Wheeler (Welsh: ). History Dyffryn Clwyd was a cantref of Medieval Wales, and from 1282 was a marcher lordship. Settlement and administration At its seaward end are the coastal resorts of Kinmel Bay (Welsh: ), Rhyl and Prestatyn whilst the town of Abergele and city of St Asaph (Welsh: ) lie just inland. The other principal towns of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llanymynech
Llanymynech is a village straddling the border between Montgomeryshire/Powys, Wales, and Shropshire, England, about 9 miles (14 km) north of the Welsh town of Welshpool. The name is Welsh for "Church of the Monks". The village is on the banks of the River Vyrnwy, and the Montgomery Canal passes through it. The border runs for the most part along the frontages of the buildings on the east (English) side of the village's main street, with the eastern half of the village in England and the western half in Wales. The Church of England parish church of St Agatha lies just in England, although the entire village lies in the same ecclesiastical parish. The border also passed right through the now closed Lion pub, which had two bars in Shropshire and one in Montgomeryshire. At one time Welsh counties were referred to as "wet" or "dry" depending on whether people could drink in pubs on Sundays. When Montgomeryshire was dry it was legal to drink on Sundays in the two English bars ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oswestry
Oswestry ( ; ) is a market town, civil parish and historic railway town in Shropshire, England, close to the Welsh border. It is at the junction of the A5, A483 and A495 roads. The town was the administrative headquarters of the Borough of Oswestry until that was abolished in 2009. Oswestry is the third-largest town in Shropshire, following Telford and Shrewsbury. At the 2011 Census, the population was 17,105. The town is five miles (8 km) from the Welsh border and has a mixed English and Welsh heritage. Oswestry is the largest settlement within the Oswestry Uplands, a designated natural area and national character area. Toponym The name ''Oswestry'' is first attested in 1191, as ''Oswaldestroe''. This Middle English name transparently derives from the Old English personal name Ōswald and the word ''trēow'' ('tree'). Thus the name seems once to have meant 'tree of a man called Ōswald'.A. D.

Llangollen
Llangollen () is a town and community, situated on the River Dee, in Denbighshire, Wales. Its riverside location forms the edge of the Berwyn range, and the Dee Valley section of the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty, with the easternmost point of the Dee Valley Way being within the town. It had a population of 3,658 at the 2011 census.

Eglwyseg
The Eglwyseg valley is an area to the north east of Llangollen in Denbighshire, Wales; it is within the boundaries of Llantysilio Community. The name also refers to a widely scattered hamlet in the valley. Formerly the old township of Eglwysegl or Eglwysegle, the area is now best known for its dramatic rock formations and unspoiled historic landscape. Topography The area is best known for the prominent Lower Carboniferous Limestone escarpment, the Eglwyseg Rocks, ( cy, Creigiau Eglwyseg, ), which runs north–south for around . The high point of the area is at on ''Mynydd Eglwyseg'' (Eglwyseg Mountain, ).

Y Felinheli
Y Felinheli (), formerly known in English as Port Dinorwic, is a village and community beside the Menai Strait ( cy, Y Fenai or ''Afon Menai'') between Bangor and Caernarfon in Gwynedd, northwest Wales. History Toponymy Etymologically, its name comes from the Welsh ''y'' meaning the, ''melin'' meaning mill and ''heli,'' meaning brine/salt-water/sea. An alternative interpretation is from ''Y Felin Heulyn'', "the mill on the River Heulyn", which refers to the river that runs into the village. Origins Y Felinheli has its origins in two hamlets, Tafarngrisiau near St Mary's Church and Aberpwll to the north-east where there was a mill on the Afon Heulyn. The mill was rebuilt closer to the sea in 1633 and gave its name to the settlement. The area was largely agricultural until the area was transformed by slate quarrying in the 19th century. A new dock was built in 1828 when lime was extracted at Brynadda and slate and lime were loaded and culm (coal dust or anthracite slack) was ...

Bangor, Gwynedd
Bangor (; ) is a cathedral city and community in Gwynedd, North Wales. It is the oldest city in Wales. Historically part of Caernarfonshire, it had a population of 18,322 in 2019, according to the Office for National Statistics. Landmarks include Bangor Cathedral, Bangor University, Garth Pier, and the Menai Suspension Bridge and Britannia Bridge which connect the city to the Isle of Anglesey.

Menai Strait
The Menai Strait ( cy, Afon Menai, the "river Menai") is a narrow stretch of shallow tidal water about long, which separates the island of Anglesey from the mainland of Wales. It varies in width from from Fort Belan to Abermenai Point to from Traeth Gwyllt to Caernarfon Castle. It then narrows to in the middle reaches (Y Felinheli and Menai Bridge) and then it broadens again. At Bangor, Garth Pier, it is wide. It then widens out, and the distance from Puffin Island (Welsh: ''Ynys Seiriol'') to Penmaenmawr is about . The differential tides at the two ends of the strait cause very strong currents to flow in both directions through the strait at different times, creating dangerous conditions. One of the most dangerous areas of the strait is known as the Swellies (or Swillies – Welsh ''Pwll Ceris'') between the two bridges. Here, rocks near the surface cause over-falls and local whirlpools, which can be of considerable danger in themselves and cause small boats to founde ...

Little Orme
The Little Orme ( cy, Rhiwledyn, also known as Trwyn y Fuwch, Trwyn y Gogarth and Y Gogarth Fach) is in height, and is a HuMP (having a minimum Hundred Metre Prominence). It is one of two headlands situated at either end of Llandudno Bay, in Conwy County Borough, Wales. The other, larger, headland is the Great Orme. It has two summits, the higher with a trig point. Uses Unlike the Great Orme, the Little Orme has not been developed for copper mining or tourism. There has been limestone quarrying since the mid-19th century on the Penrhyn Bay side, where the Little Ormes Head Quarry tramway was situated. It was centred on Porth Dyniewyd and served by its own narrow gauge railway, but quarrying ceased in 1936. There is some farming on the lower slopes. The cliffs are a popular challenge for highly experienced rock climbers. The Coast Guard Rescue Unit use the Little Orme for training. Otherwise, it is a popular sightseeing location and walking/hiking site. Ecology and en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
