Rhos Fawr
Rhos Fawr is a mountain summit in the Radnor Forest (Mid Wales), a rather isolated dome of hills to the north of the village of New Radnor. The local rocks are sedimentary shales and mudstones with some Silurian limestone. With a height of , it is the highest point in the Radnor Forest and the historic county top of Radnorshire. The summit is located on a broad heathery plateau, which is separated from Black Mixen: the eastern plateau summit, by the cwm of Harvey Dingle. To the west is Drygarn Fawr and Gorllwyn, to the northwest Plynlimon, to the north Beacon Hill and the Clun Forest (Shropshire), and to the south the Black Mountains.Nuttall, John & Anne (1999).

Plynlimon
Plynlimon, or Pumlumon in Welsh language, Welsh (also historically anglicised as Plinlimon, Plynlymmon or Plinlimmon), is the highest point of the Cambrian Mountains in Wales (taking a restricted definition of the Cambrian Mountains, excluding Snowdonia, the Berwyns and the Brecon Beacons), and the highest point in Mid Wales. It is a massif that dominates the surrounding countryside and is the highest point (List of counties of England and Wales in 1964 by highest point, county top) of Ceredigion (both the modern council area, and the historic county, also known as Cardiganshire). The highest point of the massif itself is Pen Pumlumon Fawr, which is above ordnance datum. Its other important peaks are Pen Pumlumon Arwystli, Y Garn (Plynlimon), Y Garn, Pen Pumlumon Llygad-bychan and Pumlumon Fach. Bryn yr Ŵyn, or 'hill of the lambs', is a former Dewey in the foothills. The longest river in Britain, the River Severn, has Hafren Forest, its source on the mountain, as do t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silurian
The Silurian ( ) is a geologic period and system spanning 23.5 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods ( myriapods, arachnids and hexapods) ...

Marilyns Of Wales
This is a list of Marilyn hills and mountains in the United Kingdom, Ireland and surrounding islands and sea stacks. Marilyns are defined as peaks with a prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,010 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophonous with (Marilyn) '' Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Marilyn was the first of several subsequent British Isles classifications that rely solely on prominence, including the P600s, the HuMPs, and the TuMPs. Topographic prominence is more difficult to est ... [...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 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 climate, mountains t ...

Landmark
A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern-day use, the term can also be applied to smaller structures or features that have become local or national symbols. Etymology In Old English, the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc." Starting around 1560, this interpretation of "landmark" was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by explorers and others to find their way back to their departure point, or through an area. For example, Table Mountain near Cape Town, South Africa, was used as a landmark to help sailors navigate around the southern tip of Africa during the Age of Exploration. Artificial structures ar ...

Trig Point
A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity. The station is usually set up by a mapping organisation with known coordinates and elevation published. Numerous stations are installed on summits for purposes of visibility and prominence. A graven metal plate on the top of a pillar may provide a mounting point for a theodolite or reflector, often using some form of kinematic coupling to ensure reproducible positioning. Use Trigonometrical stations form networks of triangulation. Positions of land boundaries, roads, railways, bridges and other infrastructure can be accurately located by the network, a task essential to the construction of modern infrastructure. Apart from the known stations set up by government, some temporary trigonometrical stations are set up near construction sites for monitoring the precision and progr ...

Black Mountains, Wales
The Black Mountains ( or sometimes ) are a group of hills on the England–Wales border. The Welsh part is larger and located in south-east Powys and north-west Monmouthshire, and the smaller English part is in western Herefordshire. The range may be roughly defined as those hills contained within a triangle defined by the towns of Abergavenny in the southeast, Hay-on-Wye in the north and the village of Llangors in the west. Other gateway towns to the Black Mountains include Talgarth and Crickhowell. The Welsh part of the Black Mountains is the easternmost of the four ranges of hills that comprise the Brecon Beacons National Park; they should not be confused with the westernmost, the similarly-named Black Mountain (range), Wales, Black Mountain. The range of hills is well known to walkers and ramblers for the ease of access and views from the many ridge trails, such as that on the Black Hill (Herefordshire), Black Hill in Herefordshire, at the eastern edge of the massif.

Clun Forest
Clun Forest () is a remote, rural area of open pastures, moorland and mixed deciduous/coniferous woodland in the southwest part of the English county of Shropshire and also just over the border into Powys, Wales. It was once a Royal hunting forest covering an area that stretched from Ludlow up the Clun Valley. Set aside for hunting in mediaeval times, these areas were not necessarily heavily wooded, though in today's landscape there are numerous small woods, such as Radnor Wood, together with larger areas of conifer plantations established by the Forestry Commission along the Wales–England border north of Anchor for example (the planted Ceri Forest), and to the north and southeast of Clun. The ancient Offa's Dyke runs north–south through the area (and can be walked by the Offa's Dyke Path). It gives its name to a deanery of the Church of England's Diocese of Hereford.
