Prince Llewellyn Quarry
The Prince Llewellyn quarry (also known as Bwlch Cynnud quarry, Y Foel quarry, Hendre Ddu quarry, or Prince Llywelyn quarry) was a slate quarry that stands on the west side of the Lledr Valley, ENE of Dolwyddelan. It was worked from around 1820 to 1934. History Early years The quarry opened around 1820, and was originally an open pit. The quarry was expanded in the 1840s. The road from Betws-y-Coed to Dolwyddelan was re-routed in 1846 to allow construction of a new quarry mill and Prince Llewelyn Terrace to house quarry workers. The new mill contained four horizontal sandsaws driven by a steam engine, which was later replaced with a waterwheel. An incline led down from the pit to the mill level. Chwarel Fedw In 1873, the quarry was owned by John Jones and employed about 40 men. The quarry was worked in conjunction with Chwarel Fedw on the east side of the valley. A tramway was built across the Afon Lledr to connect the two quarries and slate from Chwarel Fedw was taken ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conwy County Borough
Conwy County Borough ( cy, Bwrdeistref Sirol Conwy) is a county borough in Wales. It borders Gwynedd to the west and south, and Denbighshire to the east. Other settlements in the county borough include Abergele, Betws-y-Coed, Colwyn Bay, Conwy, Llandudno, Llandudno Junction, Llanfairfechan, Llanrwst, and Penmaenmawr. Geography The River Conwy, after which the county borough is named, lies wholly within the area: rising in Snowdonia and flowing through Llanrwst and Trefriw en route to the Irish Sea by Conwy. The river here marks the border between the historic counties of Caernarfonshire and Denbighshire. One third of the land area of the county borough lies in the Snowdonia National Park, and the council appoint three of the 18 members of the Snowdonia National Park Authority. Its total area is , making it slightly larger than Hong Kong. The eastern part includes the larger section of Denbigh Moors. The vast majority of the population live on the coast; the only settlement o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owen Gethin Jones
Owen Gethin Jones (1816 - 1883), was a Welsh building contractor, quarry owner and prominent poet. Early life Jones was born on 1 May 1816 at Tyn-y-Cae, Penmachno, to parents Owen and Grace Jones. Family In 1843, Jones married Ann Owen of Bwlch Bach, Dolwyddelan. Their son Owen Jones died in 1877 of liver failure. Their youngest daughter Jeanie G. Jones was married in 1884. Writer Jones was a prominent poet in Eisteddfod circles and was a noted local historian. His essay on Penmachno, written in the mid 19th century, was first published in 1884 (after his death) in "Gweithiau Gethin" ''(The Works of Gethin)''. The essay refers to the first nonconformist sermon in the parish in about 1784 at Penrhyn Uchaf; it describes the buildings at Dugoed farm () (the oldest part of the farmhouse was built around 1517) and reflects on the possible sites of historical significance on the farm itself, including Tomen y Castell as a possible fort and the field Cae'r Braint ("Field of Honou ...

Slate Mines In Conwy County Borough
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; for exam ...

Syncline
In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. A synclinorium (plural synclinoriums or synclinoria) is a large syncline with superimposed smaller folds. Synclines are typically a downward fold (synform), termed a synformal syncline (i.e. a trough), but synclines that point upwards can be found when strata have been overturned and folded (an antiformal syncline). Characteristics On a geologic map, synclines are recognized as a sequence of rock layers, with the youngest at the fold's center or ''hinge'' and with a reverse sequence of the same rock layers on the opposite side of the hinge. If the fold pattern is circular or elongate, the structure is a basin. Folds typically form during crustal deformation as the result of compression that accompanies orogenic mountain building.

Nod Glas Formation
The Nod Glas Formation (also known as the Nod Glas Black Shale, the Cadnant Shale, the Penarwel Mudstones or just Nod Glas) is an Ordovician lithostratigraphic group (a sequence of rock strata) in Mid Wales. The rock of the formation is made up of pyritous, graptolitic mudstone that is generally black in colour. It weathers to a soft, very well cleaved and coal-like material. The formation runs from Conwy in the north, down to Cardigan Bay in the area around Aberdyfi and Tywyn, though it is not a continuous over this area. The formation is the topmost of the Caradoc Series in North Wales, and the name refers to all the black shale beds in the area. In South Wales, the equivalent beds of shale are called the Dicranograptus Shales. North Wales Between Tywyn and Aberllefenni the Nod Glas Formation is about thick. The section between Aberllefenni and Aberangell is the type locality for the formation. North of Corris, towards Bwlch y Groes, the formation gradually thins and ceases ...
