Pen Y Garn
Pen y Garn (head of the cairn) is a mountain in the Cambrian Mountains, Mid Wales standing at 611 metres above sea level. Pen y Garn tops a 500–600 m high plateau, which includes the controversial Cefn Croes wind farm. The summit has a very large shelter cairn hollowed out from the remains of an ancient burial cairn and a trig point. The wind turbines are very near the summit.

Mountain
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 (topography), 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 Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Marilyns Of Wales
This is a list of Marilyn hills and mountains in the United Kingdom, Isle of Man and Ireland by height. 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 2,011 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 a more difficult to estimate than t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drygarn Fawr
Drygarn Fawr is a mountain in the county of Powys, Wales. It is one of the highest summits in Mid Wales at above sea level. It lies to the south of the Elan Valley Reservoirs. Rising above the remote moorland plateau of the Cambrian Mountains, and to the west of the peaks of Radnor Forest, the summit is topped by two distinctive, large cairns. The mountain has a gentle, grassy, conical shape with a few rocks near the summit. Nearby are the summits of Gorllwyn, Y Gamriw, and Drum yr Eira all over 600m. Access There are two paths to the summit. From Llannerch Yrfa, a bridleway winds up through forests in the Nant y Fedw valley before skirting the southern edge of the mountain. An alternative route may be taken starting from Rhiwnant on the edge of the Caban Coch reservoir, one of the Elan Valley Reservoirs, and following the Nant Paradwys before turning off west towards the summit cairn. Both routes pass across wild moorland and peat bog A bog or bogland is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberystwyth
Aberystwyth () is a university and seaside town as well as a community in Ceredigion, Wales. Located in the historic county of Cardiganshire, means "the mouth of the Ystwyth". Aberystwyth University has been a major educational location in Wales since the establishment of University College Wales in 1872. The town is situated on Cardigan Bay on the west coast of Wales, near the confluence of the River Ystwyth and Afon Rheidol. Following the reconstruction of the harbour, the Ystwyth skirts the town. The Rheidol passes through the town. The seafront, with a pier, stretches from Constitution Hill at the north end of the Promenade to the harbour at the south. The beach is divided by the castle. The town is divided into five areas: Aberystwyth Town; Llanbadarn Fawr; Waunfawr; Llanbadarn; Trefechan; and the most populous, Penparcau. In 2011 the population of the town was 13,040. This rises to nearly 19,000 for the larger conurbation of Aberystwyth and Llanbadarn Fawr. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pen Pumlumon Llygad-bychan
Pen Pumlumon Llygad-bychan is a subsidiary summit of Pen Pumlumon Fawr and the third highest summit on the Plynlimon massif, a part of the Cambrian Mountains in the county of Ceredigion, Wales. It is not named on Ordnance Survey walking maps. The summit is boggy, and is marked by a few stones. The views include Rhos Fawr, Drygarn Fawr, Pen y Garn to the south and Aran Fawddwy, Glasgwm, Tarrenhendre and Tarren y Gesail to the north. The River Wye, has its source just south of the summit.

Triangulation Station
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 nomenclature varies regionally: they are generally known as trigonometrical stations or triangulation stations in North America, trig points in the United Kingdom, trig pillars in Ireland, trig stations or trig points in Australia and New Zealand, and trig beacons in South Africa. Use The station is usually set up by a government with known coordinates and elevation published. Many stations are located on hilltops for the purposes of visibility. 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. Trigonometrical stations are grouped together to form a network of triangulation. Positions of all land boundaries, roads, railways, bridges and other ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Mid Wales
Mid Wales ( cy, Canolbarth Cymru or simply ''Y Canolbarth'', meaning "the midlands") or Central Wales refers to a region of Wales, encompassing its midlands, in-between North Wales and South Wales. The Mid Wales Regional Committee of the Senedd covered the unitary authority areas of Ceredigion and Powys and the area of Gwynedd that had previously been the district of Meirionnydd. A similar definition is used by the BBC. The Wales Spatial Plan defines a region known as "Central Wales" which covers Ceredigion and Powys. Mid Wales is dominated by the Cambrian Mountains, including the Green Desert of Wales. The region is sparsely populated, with an economy dependent on farming and small businesses.
