Clipyn Du
Clipyn Du is a mountain in northern Powys in Wales. Also known as ''Tarren Bwlch-Gwyn'' or ''Siambwr Trawsfynydd'', it is one of the higher summits of the area and is located a few miles north of Plynlimon (Pumlumon). It has an elevation of and a topographic prominence In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contou ... of , so is classed as a HuMP, having over 100 metres of prominence. Tarren Bwlch-Gwyn is the name of a steep-sided escarpment nearby. Nearby is a lake, ''Glaslyn''.

HuMP
The mountains and hills of the British Isles are categorised into various lists based on different combinations of elevation, prominence, and other criteria such as isolation. These lists are used for peak bagging, whereby hillwalkers attempt to reach all the summits on a given list, the oldest being the 282 Munros in Scotland, created in 1891. A height above 2,000 ft, or more latterly 610 m, is considered necessary to be classified as a mountain – as opposed to a hill – in the British Isles. With the exception of Munros, all the lists require a prominence above . A prominence of between (e.g. some Nuttalls and Vandeleur-Lynams), does not meet the International Climbing and Mountaineering Federation (UIAA) definition of an "independent peak", which is a threshold over . Most lists consider a prominence between as a "top" (e.g. many Hewitts and Simms). Marilyns, meanwhile, have a prominence above , with no additional height threshold. They range from small hills to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambrian Mountains
The Cambrian Mountains ( cy, Mynyddoedd Cambria, in a narrower sense: ''Elenydd'') are a series of mountain ranges in Wales. The term ''Cambrian Mountains'' used to apply to most of the upland of Wales. Since the 1950s, its application has become increasingly localised to the geographically homogeneous Mid Wales uplands, known in Welsh as ''Elenydd'', which extend from Pumlumon to Radnor Forest in the east and Mynydd Mallaen to the south. This barren and sparsely populated 'wilderness' has been referred to as the Desert of Wales. The area includes the sources of the River Severn and River Wye and was unsuccessfully proposed as a national park in the 1960s and 1970s. The highest point of the range is Plynlimon, at . The wider, more historic, use of the term also includes Snowdonia in North Wales, and the Brecon Beacons and Black Mountains in South Wales. They range in height up to in Snowdonia. Geology and topography While Snowdonia contains a mix of volcanic rocks an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumlumon
Pumlumon (historically anglicised in various ways including ''Plynlimon,'' Plinlimon and 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. The longest river in Britain, the River Severn, has Hafren Forest, its source on the mountain, as do the rivers River Wye, Wye and River Rheidol, Rheidol. Folklore says there is a sleeping giant ...

Montgomeryshire
Montgomeryshire, also known as ''Maldwyn'' ( cy, Sir Drefaldwyn meaning "the Shire of Baldwin's town"), is one of thirteen historic counties of Wales, historic counties and a former administrative county of Wales. It is named after its county town, Montgomery, Powys, Montgomery, which in turn is named after one of William the Conqueror's main counsellors, Roger de Montgomerie, 1st Earl of Shrewsbury, Roger de Montgomerie, who was the 1st Earl of Shrewsbury. Montgomeryshire today constitutes the northern part of the Subdivisions of Wales#Principal areas of Wales, principal area of Powys. The population of Montgomeryshire was 63,779 according to the United Kingdom Census 2011, 2011 census, with a low population density of just 75 people per square mile (29 people per square km). The current area is 2,174 square km (839 square miles). The largest town is Newtown, Powys, Newtown, followed by Welshpool and Llanidloes.

Powys
Powys (; ) is a Local government in Wales#Principal areas, county and Preserved counties of Wales, preserved county in Wales. It is named after the Kingdom of Powys which was a Welsh succession of states, successor state, petty kingdom and principality that emerged during the Middle Ages following the end of Roman rule in Britain. Geography Powys covers the historic counties of Montgomeryshire and Radnorshire, most of Brecknockshire, and part of Denbighshire (historic), historic Denbighshire. With an area of about , it is now the largest administrative area in Wales by land and area (Dyfed was until 1996 before several Preserved counties of Wales, former counties created by the Local Government Act 1972 were abolished). It is bounded to the north by Gwynedd, Denbighshire and Wrexham County Borough; to the west by Ceredigion and Carmarthenshire; to the east by Shropshire and Herefordshire; and to the south by Rhondda Cynon Taf, Merthyr Tydfil County Borough, Caerphilly County Bor ...

Plynlimon
Pumlumon (historically anglicised in various ways including ''Plynlimon,'' Plinlimon and 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 (county top) of Ceredigion (both the modern council area, and the historic county, also known as Cardiganshire).

Topographic Prominence
In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's ''key col'' (the highest col surrounding the peak) is a unique point on this contour line and the ''parent peak'' is some higher mountain, selected according to various criteria. Definitions The prominence of a peak may be defined as the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following way: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''key Saddle point, saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting pat ...
