Grwyne Fawr
The Grwyne Fawr is a river in the Brecon Beacons National Park in south Wales. A section of it forms the administrative border between Powys and Monmouthshire and also of the historic counties of Brecon and Monmouth. The river and its major tributary the Grwyne Fechan flow into the River Usk at Glangrwyney. The name probably originates from ''gweryn'' or ''gwerynau'' and ''mawr/fawr'' meaning 'large river at the wet place'. The Gwryne Fawr rises at Blaen Grwyne Fawr on the southern slopes of Rhos Dirion in the Black Mountains and follows a southeastward course for several miles, its flow interrupted by the presence of Grwyne Fawr Reservoir, the only waterbody within this range of hills. Some way below the reservoir, Mynydd Du Forest clothes the sides of the valley. Though a public road penetrates the valley as far as the north end of the forest, the valley is very sparsely populated. It is only approaching the hamlet of Partrishow that the valley takes on a farmed appear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llanbedr, Crickhowell
Llanbedr is a small village northeast of Crickhowell in the county of Powys, Wales and the community of Vale of Grwyney. It lies above the river known as the Grwyne Fechan just above its confluence with the Grwyne Fawr in the southern reaches of the Black Mountains range. The village lies within the shadow of Table Mountain, an outlying spur of Pen Cerrig-calch on which is perched the Iron Age hill fort of Crug Hywel Crug Hywel is an Iron Age Celtic hillfort, with a clearly visible earth and stone ditch and rampart.

Caradog Ap Gruffydd
Caradog ap Gruffydd (died 1081) was a Prince of Gwent in south-east Wales in the time of Gruffydd ap Llywelyn and the Norman conquest, who reunified his family's inheritance of Morgannwg and made repeated attempts to reunite southern Wales by claiming the inheritance of the Kingdom of Deheubarth. Background & Lineage The family's stronghold was the Kingdom of Glywysing and the Kingdom of Gwent, and Caradog was the grandson of the King of Glywysing, Rhydderch ab Iestyn who had been able to take over the throne of Deheubarth from 1023 until his death in 1033. Caradog's father Gruffydd ap Rhydderch, after receiving the Lordshop of Caerleon in 1031, also inherited Glywysing, and became King of Deheubarth in 1045, in the same year as Gruffydd's second cousin, Cadwgan ap Meurig, inherited the Kingdom of Gwent from his father Meurig ap Hywel.Ashley, Mike (1998) ''The Mammoth Book of British Kings and Queens '' (Carol & Graf) Both of them were co-descendants of Owain, son of Morg ...

Richard De Clare, 1st Earl Of Hereford
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below). People named Richard Multiple people with the same name * Richard Andersen (other) * Richard Anderson (other) * Richard Cartwright (other) * Ri ...

Marcher Lord
A Marcher lord () was a noble appointed by the king of England to guard the border (known as the Welsh Marches) between England and Wales. A Marcher lord was the English equivalent of a margrave (in the Holy Roman Empire) or a marquis (in France) before the introduction of the title of "marquess" in Britain; no Marcher lord ever bore this rank. In this context the word ''march'' means a border region or frontier, and is cognate with the verb "to march", both ultimately derived from Proto-Indo-European ''*mereg-'', "edge" or "boundary". The greatest Marcher lords included the earls of Chester, Gloucester, Hereford, Pembroke and Shrewsbury (see also English earls of March). County palatine Some strong earldoms along the Welsh border were granted the privileged status of county palatine shortly after the Norman Conquest, but only that based on Chester survived for a long period. The term particularly applies to Anglo-Norman lords in Wales, who had complete jurisdiction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normans
The Normans (Norman language, Norman: ''Normaunds''; french: Normands; la, Nortmanni/Normanni) were a population arising in the medieval Duchy of Normandy from the intermingling between Norsemen, Norse Viking settlers and indigenous West Francia, West Franks and Gallo-Roman culture, Gallo-Romans. The term is also used to denote emigrants from the duchy who conquered other territories such as England and Sicily. The Norse settlements in West Francia followed a series of raids on the French northern coast mainly from Denmark, although some also sailed from Norway and Sweden. These settlements were finally legitimized when Rollo, a Scandinavian Viking leader, agreed to swear fealty to Charles the Simple, King Charles III of West Francia following the Siege of Chartres (911), siege of Chartres in 911. The intermingling in Normandy produced an Ethnic group, ethnic and cultural "Norman" identity in the first half of the 10th century, an identity which continued to evolve over the ce ...

Glacial Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...
