Mynydd Illtud
Mynydd Illtud is an extensive area of common land near Libanus, Powys, Wales, located in the Brecon Beacons National Park and some three miles south-west of Brecon. The common is an undulating plateau lying between above sea level. Its highest points are at Allt Lom and at Twyn y Gaer trig point overlooking the valley of the River Usk. Twyn y Gaer is the site of an Iron Age hill fort. Geology Like Cefn Llechid and Fforest Fach to the west, Mynydd Illtud is formed from the mudstones and sandstones of the St. Maughans Formation of the Old Red Sandstone laid down during the Devonian period. The sandstones have been quarried in places such as at Allt Lom.The area was overrun by ice during the last ice age and evidence of this is seen in the glacial till which is spread across this undulating plateau and the occasional erratic block of sandstone. Traeth Mawr and Traeth Bach, two rock hollows towards the south-western end of the common are now filled with peat, core sections of ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mountains And Hills Of Powys
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Earthworks (archaeology)
In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks can themselves be archaeological features, or they can show features beneath the surface. Types Earthworks of interest to archaeologists include hill forts, henges, mounds, platform mounds, effigy mounds, enclosures, long barrows, tumuli, ridge and furrow, mottes, round barrows, and other tombs. * Hill forts, a type of fort made out of mostly earth and other natural materials including sand, straw, and water, were built as early as the late Stone Age and were built more frequently during the Bronze Age and Iron Age as a means of protection. See also Oppidum. * Henge earthworks are those that consist of a flat area of earth in a circular shape that are encircled by a ditch, or several circular ditches, with a bank on the outside of the ditch built with the earth from inside the ditch. They are believed to have been used as mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warren (domestic)
A warren is a network of wild rodent or lagomorph, typically rabbit burrows. Domestic warrens are artificial, enclosed establishment of animal husbandry dedicated to the raising of rabbits for meat and fur. The term evolved from the medieval Anglo-Norman concept of free warren, which had been, essentially, the equivalent of a hunting license for a given woodland. Architecture of the domestic warren The cunicularia of the monasteries may have more closely resembled hutches or pens, than the open enclosures with specialized structures which the domestic warren eventually became. Such an enclosure or ''close'' was called a ''cony-garth'', or sometimes ''conegar'', ''coneygree'' or "bury" (from "burrow"). Moat and pale To keep the rabbits from escaping, domestic warrens were usually provided with a fairly substantive moat, or ditch filled with water. Rabbits generally do not swim and avoid water. A '' pale'', or fence, was provided to exclude predators. Pillow mounds The m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabbit
Rabbits, also known as bunnies or bunny rabbits, are small mammals in the family Leporidae (which also contains the hares) of the order Lagomorpha (which also contains the pikas). ''Oryctolagus cuniculus'' includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. ''Sylvilagus'' includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit is, in many areas of the world, a part of daily life—as food, clothing, a companion, and a source of artistic inspiration. Although once considered rodents, lagomorphs like rabbits have been discovered to have diverged separately and earlier than their rodent cousins and have a number of traits rodents lack, like two extra incis ...

Sarn Helen
Sarn Helen refers to several stretches of Roman road in Wales. The route, which follows a meandering course through central Wales, connects Aberconwy in the north with Carmarthen in the west. Despite its length, academic debate continues as to the precise course of the Roman road. Many sections are now used by the modern road network while other parts are still traceable. However, there are sizeable stretches that have been lost and are unidentifiable. The route is named after Saint Elen of Caernarfon, a Celtic saint, whose story is told in ''The Dream of Macsen Wledig'', part of the ''Mabinogion''. She is said to have ordered the construction of roads in Wales during the late 4th century. Route Aberconwy–Carmarthen In the north the route is believed to follow the western bank of the river Conwy from Canovium, a fort at Caerhun, passing through Trefriw, then leading on to Betws-y-Coed, with a branch leading to Caer Llugwy near Capel Curig. The route then passed through Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Road
Roman roads ( la, viae Romanae ; singular: ; meaning "Roman way") were physical infrastructure vital to the maintenance and development of the Roman state, and were built from about 300 BC through the expansion and consolidation of the Roman Republic and the Roman Empire. They provided efficient means for the overland movement of armies, officials, civilians, inland carriage of official communications, and trade goods. Roman roads were of several kinds, ranging from small local roads to broad, long-distance highways built to connect cities, major towns and military bases. These major roads were often stone-paved and metaled, cambered for drainage, and were flanked by footpaths, bridleways and drainage ditches. They were laid along accurately surveyed courses, and some were cut through hills, or conducted over rivers and ravines on bridgework. Sections could be supported over marshy ground on rafted or piled foundations.Corbishley, Mike: "The Roman World", page 50. Warwick Press, ...
