Henrhyd Waterfall
Henrhyd Falls (Welsh: ''Sgwd Henrhyd'') in the Brecon Beacons National Park, Wales, is the tallest waterfall in southern Wales with a drop of . It lies on National Trust land, in the county of Powys. The nearest settlement to it is Coelbren, on the road between Glynneath and Abercraf. Though not in the core of the area, it is considered by many to constitute a part of Wales' celebrated Waterfall Country. Geology The falls occur where the small river, the Nant Llech () drops over the faulted edge of a hard sandstone known as the Farewell Rock which forms the top half of the rock face and which forms the base of the South Wales Coal Measures. Beneath this, and forming much of the recessed portion of the drop, is the Subcrenatum Sandstone separated from the Farewell Rock above by the ''Subcrenatum'' marine band. Both the marine band and sandstone are part of the Bishopston Mudstone Formation included within the Marros Group, the modern name in South Wales for the assemblage of ...

Brecon Beacons National Park
The Brecon Beacons National Park ( cy, Parc Cenedlaethol Bannau Brycheiniog) is one of three national parks in Wales, and is centred on the Brecon Beacons range of hills in southern Wales. It includes the Black Mountain (range), Black Mountain ( cy, Y Mynydd Du) in the west, Fforest Fawr (translates as 'great forest') and the Brecon Beacons in the centre and the Black Mountains, Wales, Black Mountains ( cy, Y Mynydd Du or Mynyddoedd Duon) in the east. Description The Brecon Beacons National Park was established in 1957, the last of the three Welsh parks designated after Snowdonia in 1951 and the Pembrokeshire Coast in 1952.

Marros Group
The Marros Group is the name given to a suite of rocks of Namurian age laid down during the Carboniferous Period in South Wales. These rocks were formerly known as the Millstone Grit Series but are now distinguished from the similar but geographically separate rock sequences of the Pennines and Peak District of northern England and northeast Wales by this new name. Stratigraphy The Group comprises a thick unit of coarse sandstone known as the Twrch Sandstone (formerly the ‘Basal Grit’) which is overlain by the Bishopston Mudstone and the Telpyn Point Sandstone. The mudstones of these latter two formations was formerly known as the ‘Middle Shales’, a name reflecting the position of this sequence sandwiched between the Basal Grit below and the Farewell Rock, the lowermost sandstone of the South Wales Coal Measures, above. The mudstone itself contains a few bands of sandstone such as the ‘Twelve Foot Sandstone’ and locally the ‘Cumbriense Sandstone’. Likewise the Twrc ...

Waterfalls Of Powys
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Fforest Fawr
Fforest Fawr is an extensive upland area in the county of Powys, Wales. Formerly known as the Great Forest of Brecknock in English, it was a royal hunting area for several centuries but is now used primarily for sheep grazing, forestry, water catchment and recreation. It lies within the Brecon Beacons National Park. Extent The area extends from the edge of the Black Mountain in the west eastwards to the A470 Brecon to Merthyr Tydfil road, just west of the Brecon Beacons themselves. It includes the peaks of Fan Fawr (734 m), Fan Frynych (629 m), Craig Cerrig-gleisiad (629 m), Fan Llia (632 m), Fan Nedd (663 m), Fan Gyhirych (725 m), Fan Bwlch Chwyth (603 m) and Cefn Cul (562 m). Traditionally Fforest Fawr also included the peaks of Fan Hir and Fan Brycheiniog, although the modern recreational use of the name tends to be restricted to the area east of the Black Mountain of which they form a part. Geology The area is largely underlain by sandstones and mudstones of the Old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ystradfellte
Ystradfellte is a village and community in Powys, Wales, about north of Hirwaun, with 556 inhabitants. It belongs to the historic county of Brecknockshire (Breconshire) and the Fforest Fawr area of the Brecon Beacons National Park, beside the Afon Mellte river. The village is linked by minor roads with Heol Senni to the north and the A4059 north of Penderyn, and with Pontneddfechan, which lies in the community, at the head of the Vale of Neath to the south. History Ystradfellte is chiefly known in history as the place where the Welsh nobleman and rebel leader Llywelyn Bren surrendered at the end of his revolt of 1316. Llywelyn gave himself up on the condition that his men be spared, but was himself put to death in 1318 at Cardiff. The village was connected to mains electricity in 1960, as one of the last communities in the whole of England and Wales to be wired. Outlying properties in the Nedd Fechan valley had to wait until December 2005 for their connection. Features The v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Geological Survey Of Canada
The Geological Survey of Canada (GSC; french: Commission géologique du Canada (CGC)) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations. History In September 1841, the Province of Canada legislature passed a resolution that authorized the sum of £1,500 sterling be granted to the government for the estimated expense of performing a geological survey of the province. In 1842, the Geological Survey of Canada was formed to fulfill this request.Christy Vodden (1992)No Stone Unturned: The First 150 years of the Geological Survey of Canada Geological Survey of Canada Web site William Edmond Logan was in Montreal at the time and made it known that he was interested in participating in this survey.

William Edmond Logan
Sir William Edmond Logan, FRSE FRS FGS (20 April 1798 – 22 June 1875), was a Canadian-born geologist and the founder and first director of the Geological Survey of Canada. Life William Edmond Logan was born into a well-to-do Montreal family in 1798, the third son of William Logan, a baker and owner of real estate, and Janet Edmond, both originally from Scotland. Logan was sent to Edinburgh to receive an education. As was common at the time for young men of means, he learned languages (French, Spanish, some Gaelic and German), music (flute), and became an accomplished artist. In the 1830s, Logan became fascinated with geology while managing a copper-smelting works near Swansea, Wales, on behalf of his uncle, Hart Logan. His self-taught talent for the subject soon brought his geological maps and interpretations to the attention of the most eminent geologists of Great Britain, and it was their later recommendations that clinched Logan's appointment as the founding director of t ...

It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Marine Band (geology)
A marine band, in geology, is a bed of rock, commonly black or dark grey shale, containing an abundance of fossils of marine organisms. These strata represent episodes of flooding by seawater and are important in enabling the comparison or correlation of rock sequences in different localities. Examples * Maltby Marine Band – England * Milngavie Marine Band – Scotland * Redhall Marine Band – Scotland See also *Marine transgression A marine transgression is a geologic event during which sea level rises relative to the land and the shoreline moves toward higher ground, which results in flooding. Transgressions can be caused by the land sinking or by the ocean basins filling ... References Fossils Shale Mudstone {{geology-stub ...
