River Alyn
The River Alyn ( cy, Afon Alun) is a tributary of the River Dee, in north-east Wales. The River Alyn rises at the southern end of the Clwydian hills and the Alyn Valley forms part of the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty. The main town on the river is Mold, the county town of Flintshire. It lends its name to the constituencies of Alyn and Deeside in the UK Parliament and the Senedd. The River Alyn crosses the carboniferous limestone from Halkyn Mountain and north through the Loggerheads area before heading southeast, passing through Mold before reaching its confluence with the River Dee to the northeast of Wrexham. Between Loggerheads and Rhydymwyn it runs through the Alyn Gorge, which is the site of the caves Ogof Hesp Alyn, Ogof Hen Ffynhonnau and Ogof Nadolig Ogof Nadolig is a cave in the Alyn Gorge near Cilcain, Flintshire, Wales. It is mostly crawling, long, and ends with a shaft up to the surface and a locked manhole cover. ...

Hope, Flintshire
Hope ( cy, Yr Hôb) is a small village and community in Flintshire, north-east Wales. The village is located approximately 3 miles / 4.5 km from the Wales-England border, on the course of the River Alyn, and less than 5 miles from Wrexham. Hope is one of several villages including Caergwrle, Abermorddu and Cefn-y-bedd which together form the community. At the 2001 Census, community the population was 2,522, increasing to 4,224 at the 2011 Census partly due to boundary changes. One of the major features in the area is Hope Mountain (''Mynydd yr Hob''), to the west of the village. History ''Yr Hob'' was originally the name of a commote within the cantref of Maelor in the medieval Kingdom of Powys. Both the Welsh and English language names are derived from an Old English word ''hop'' meaning "enclosed land in a marsh", a relic of Mercian settlement in the area.Owen, H. W. (2015) ''The Place-names of Wales'', UWP, p.53 In 1086, when the Domesday Book was compiled, Hope w ...

Ogof Hen Ffynhonnau
Ogof Hen Ffynhonnau (sometimes known in English as Poacher's Cave) lies in the Alyn Gorge in Flintshire, Wales close to Ogof Hesp Alyn. It was discovered in 1978 after excavation allowed access to Dyer's Adit. Being below a dry river bed, the cave can be prone to flooding in wet weather. There is a short ladder pitch just inside the entrance, and it makes a short trip suitable for novice cavers. History The name Poacher's Cave was coined during an acrimonious dispute between the Northern Pennine Club Northern Pennine Club (NPC) is one of the oldest and largest caving clubs in the UK. Founded in 1946, the Northern Pennine Club was one of the caving clubs started by various cavers affected by the politics of the British Speleological Association i ... who were originally digging the entrance and the North Wales Caving Club who actually broke through one day while the diggers were away. Different sides of the story are available. The following account from the Northern Penni ...

Ogof Hesp Alyn
Ogof Hesp Alyn (Welsh for: ''Dry Alyn Cave'') was discovered by North Wales Caving Club in 1973 in the Alyn Gorge near Cilcain, Flintshire, Wales. Reaching the end of the cave is a serious commitment involving 24 pitches and the draining of two sumps. The proliferation of short, awkward and muddy pitches appear best suited to be tackled by wire ladders, but in the 1980s a team of divers from the Wessex Caving Club who passed the sumps, concluded that single rope technique was preferable, avoiding the need for excessive numbers of people to carry the equipment. A perpetual siphon has since been used at the first sump which does a good job of keeping the water level relatively low, when working properly. A BCRA grade 5b survey of the cave exists that was created by North Wales Caving Club in two phases, in periods during the original 70s exploration, and further exploration beyond the sumps in the 80s. As well as the main passage that meanders through the cave there are several ...

Alyn Gorge
The Alyn Gorge is a gorge section of the River Alyn north between Loggerheads and Rhydymwyn in Wales. The west side of the valley rises gently to Moel Famau, while the east bank is along parts a cliff with evidence of tram lines and old quarry workings. The path along the edge of the gorge is well maintained, with metal bridges and barriers across sites which are popular with climbers. The character of the gorge changes at Cilcain where a small bridge crosses the watercourse at . The water sinks into the river bed a hundred metres north from this place and enters the caves Ogof Hen Ffynhonnau and Ogof Hesp Alyn, which were discovered in the 1970s after the watertable had changed due to the mine-workings earlier in the century. High on the east bank near these two entrances is the small cave of Ogof Nadolig. The Alyn Gorge and caves have been designated as a Site of Special Scientific Interest A Site of Special Scientific Interest (SSSI) in Great Britain or an Area ...

Loggerheads, Wales
Loggerheads is a village in Denbighshire, Wales on the River Alyn, a tributary of the River Dee. It is the location of Loggerheads Country Park which follows the course of the River Alyn through karstic limestone countryside including the sites of old lead mines and mills. There is a working flour mill on site. A leat or leete, built around 1824, follows the side of the valley nearby and was used to carry water to the lead mines of Mold Mines, on land owned by the Grosvenor family. It is now the popular Leete Walk. The name Loggerheads may come from the dispute over estate boundaries between the lordships of Mold and Llanferres. The final boundary is marked by ''Carreg Carn March Arthur'' which is said to bear the imprint of Arthur's horse's hoof after it jumped from the nearby mountain, Moel Famau Moel Famau is the highest hill in the Clwydian Range and the highest point (county top) of the county of Flintshire in Wales (both the historic county and the current counc ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ...

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lin ...
