Ynys Enlli
Bardsey Island ( cy, Ynys Enlli), known as the legendary "Island of 20,000 Saints", is located off the Llŷn Peninsula in the Welsh county of Gwynedd. The Welsh name means "The Island in the Currents", while its English name refers to the "Island of the Bards", or possibly the Viking chieftain, "Barda". At in area it is the fourth largest offshore island in Wales, with a population of only 11. The north east rises steeply from the sea to a height of at Mynydd Enlli, which is a Marilyn, while the western plain is low and relatively flat cultivated farmland. To the south the island narrows to an isthmus, connecting a peninsula on which the lighthouse stands.Gwynedd Archaeological Trust : ''Bardsey'' Retrieved 16 August 2009 to 2010 Since 1974 it has been included in the |
Daily Post (North Wales)
The ''Daily Post'' is a daily newspaper for the North Wales region of Wales. Its website is branded ''North Wales Live''. The newspaper gained independence from the ''Liverpool Daily Post'' in 2003 which later ceased production in December 2013. ABC data from 2021 notes the paper has a circulation of 12,478. It was based on Vale Road, Llandudno Junction, from 2001 to 2017. In May 2017, it moved to its new and current base at Bryn Eirias on Colwyn Bay Colwyn Bay ( cy, Bae Colwyn) is a town, community and seaside resort in Conwy County Borough on the north coast of Wales overlooking the Irish Sea.

North Wales Pilgrims Way
The North Wales Pilgrim's Way ( cy, Taith Pererin Gogledd Cymru) is a long-distance walking route in North Wales, running from near Holywell in the east to Bardsey Island ( cy, Ynys Enlli) in the west. The first half of the trail takes an inland route, with the second half (from Abergwyngregyn onwards) following the north coast of the Llŷn Peninsula. It measures 133.9 miles (215 km) in length, and was officially launched at Porth y Swnt, Aberdaron on 10 July 2014. Development of the trail started in 2011, and its official opening followed a number of alterations to the original route to suit local concerns. The route, which is marked by waymarker disks, makes use of existing public rights of way, including sections of the Wales Coast Path, and along the way it visits many small stone churches, many dedicated to key Celtic Saints, which can provide shelter and rest along the trail. Whilst, historically, pilgrims would have made their way across North Wales to Bardsey Isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Igneous
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies ( marine snow). Sedimentation may also occur as dissolved minerals precipitate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clast
Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus,Essentials of Geology, 3rd Ed, Stephen Marshak, p. G-3 chunks, and smaller grains of rock broken off other rocks by physical weathering.Essentials of Geology, 3rd Ed, Stephen Marshak, p. G-5 Geologists use the term clastic to refer to sedimentary rocks and particles in sediment transport, whether in suspension or as bed load, and in sediment deposits. Sedimentary clastic rocks Clastic sedimentary rocks are rocks composed predominantly of broken pieces or ''clasts'' of older weathered and eroded rocks. Clastic sediments or sedimentary rocks are classified based on grain size, clast and cementing material (matrix) composition, and texture. The classification factors are often useful in determining a sample's environment of deposition. An example of clastic environment would be a river system in which the full range of grains being transported b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gwna Mélange
The Gwna Group is a late Precambrian ( Ediacaran) / Cambrian lithostratigraphic group (a sequence of rock strata) in northwest Wales. The name is derived from the Afon Gwna, a river near Bodorgan on Anglesey where the strata are exposed. This rock sequence is also commonly referred to as the Gwna Mélange. Outcrops These rocks are exposed across various parts of Anglesey and along the northern coast of Llŷn and at Bardsey Island. The extensive coastal cliffs at each of these locations affords excellent exposure. Lithology and stratigraphy The Group is considered to represent the result of an olistostrome, a giant underwater gravity slide, which occurred probably as a result of tectonic activity at some time after 614 million years ago. It includes clasts, at all sizes from millimetres up to a kilometre or more, of a diverse range of both sedimentary and igneous rocks. Since deposition the group as a whole has been subject to low grade metamorphism Metamorphism is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mélange
In geology, a mélange is a large-scale breccia, a mappable body of rock characterized by a lack of continuous bedding and the inclusion of fragments of rock of all sizes, contained in a fine-grained deformed matrix. The mélange typically consists of a jumble of large blocks of varied lithologies. Both tectonic and sedimentary processes can form mélange. Mélange occurrences are associated with thrust faulted terranes in orogenic belts. A mélange is formed in the accretionary wedge above a subduction zone. The ultramafic ophiolite sequences which have been obducted onto continental crust are typically underlain by a mélange. Smaller-scale localized mélanges may also occur in shear or fault zones, where coherent rock has been disrupted and mixed by shearing forces. Large-scale melanges formed in active continental margin settings generally consist of altered oceanic crustal material and blocks of continental slope sediments in a sheared mudstone matrix. The mixing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.

Grey Seals
The grey seal (''Halichoerus grypus'') is found on both shores of the North Atlantic Ocean. In Latin Halichoerus grypus means "hook-nosed sea pig". It is a large seal of the family Phocidae, which are commonly referred to as "true seals" or "earless seals". It is the only species classified in the genus ''Halichoerus''. Its name is spelled gray seal in the US; it is also known as Atlantic seal and the horsehead seal. Taxonomy There are two recognized subspecies of this seal: The type specimen of ''H. g. grypus'' ( Zoological Museum of Copenhagen specimen ZMUC M11-1525, caught off the island of Amager, Danish part of the Baltic Sea) was believed lost for many years but was rediscovered in 2016, and a DNA test showed it belonged to a Baltic Sea specimen rather than from Greenland, as had previously been assumed (because it was first described in Otto Fabricius' book on the animals in Greenland: ''Fauna Groenlandica''). The name ''H. g. grypus'' was therefore transferred to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harbour Porpoise
The harbour porpoise (''Phocoena phocoena'') is one of eight extant species of porpoise. It is one of the smallest species of cetacean. As its name implies, it stays close to coastal areas or river estuaries, and as such, is the most familiar porpoise to whale watchers. This porpoise often ventures up rivers, and has been seen hundreds of kilometres from the sea. The harbour porpoise may be polytypic, with geographically distinct populations representing distinct races: ''P. p. phocoena'' in the North Atlantic and West Africa, ''P. p. relicta'' in the Black Sea and Sea of Azov, an unnamed population in the northwestern Pacific and ''P. p. vomerina'' in the northeastern Pacific. Taxonomy The English word porpoise comes from the French (Old French , 12th century), which is from Medieval Latin , which is a compound of ''porcus'' (pig) and (fish). The old word is probably a loan-translation of a Germanic word, compare Danish ''marsvin'' and Middle Dutch ''mereswijn'' (sea swin ...
