Black Mixen
Black Mixen ( cy, Y Domen Ddu) is a subsidiary summit of Rhos Fawr or Great Rhos in the Radnor Forest. The summit is large peat bog plateau. The summit is marked with a cairn, and is next to a radio transmitter and its building. Black Mixen is the only Nuttall to have a communications mast (a radio transmitter) on its summit. To the east is Bache Hill, to the south are the Black Mountains, to the west is the Great Rhos plateau. The summit cairn is probably of Bronze Age The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization.

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).

The Hewitt classification was suggested by Alan Dawson in his 1992 book, "The Relative Hills of Britain". Dawson originally called his Hewitts "Sweats", from "Summits - Wales and England Above Two thousand", before settling on the label Hewitt. In a series of three booklets edited by Dave Hewitt, the list of English Hewitts was published in 1997, and the list of Welsh Hewitts was also published in 1997, and the list of Irish Hewitts was published in 1998. Hewitts were designed to address one of the criticisms of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nuttall (hill)
This is a list of Nuttall mountains in England and Wales by height. Nuttalls are defined as peaks above in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above ; a mix of imperial and metric thresholds. The Nuttall classification was suggested by Anne and John Nuttall in their 1990 two–volume book, "The Mountains of England and Wales". The list was updated with subsequent revised editions by the Nuttalls. Because of the prominence threshold of only , the list is subject to ongoing revisions. In response, Alan Dawson introduced the Hewitts, with a higher prominence threshold of . This was the prominence threshold that the UIAA set down in 1994 for an "independent" peak. In 2010, Dawson replaced his Hewitts with the fully "metric" Simms, consisting of a height threshold of , and a prominence threshold of . However, both the Nuttall and Hewitt classifications have become popular with peak baggers, and both remain in ...

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 ...

Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

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.

Radnor Forest
Radnor Forest ( cy, Fforest Clud) in the county of Radnorshire, Wales is a rock dome composed of Silurian shales, mudstones and limestone in Mid Wales. It is a forest in the medieval sense of the word (an area of land set aside for hunting). It lies within the Welsh Marches region since Offa's Dyke lies nearby to the east. The area lies to the north of the Black Mountains and to the east of the Cambrian Mountains. Hergest Ridge is immediately to the south-east of the area (just across the English border into Herefordshire), near the small town of Kington. The highest point in the area is Rhos Fawr a broad plateau which reaches , and is equipped with a trig point to mark the summit. A similar plateau adjoining to the east, Black Mixen is the only Nuttall to have a communications mast (a radio transmitter) on its summit. Geology The massif is formed from argillaceous rocks of Ludlow age, i.e. late Silurian around 425 million years ago. The strata are exposed around Harl ...

Radio Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters, e ...

Bache Hill
Bache Hill ( cy, Bryn Bach) is a subsidiary summit of Rhos Fawr or Great Rhos, in the Radnor Forest in Wales. It is located to the east of Black Mixen. The summit is marked by a trig point built on an ancient burial mound, probably of Bronze Age The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second prin ... date, like most of the summit cairns and round barrows in Wales. Some controversy arises from the burial mound; in that 610 metres might be the top of the man-made mound. Some walkers therefore doubt Bache Hill's 2,000-foot status. However, the latest OS Explorer Maps shows a large 610-metre contour round the summit.Nuttall, John & Anne (1999). The Mountains of England & Wales - Volume 1: Wales (2nd edition ed.).

Black Mountains, Wales
The Black Mountains ( cy, Y Mynydd Du or sometimes ) are a group of hills spread across parts of Powys and Monmouthshire in southeast Wales, and extending across the England–Wales border into Herefordshire. They are the easternmost of the four ranges of hills that comprise the Brecon Beacons National Park, and are frequently confused with the westernmost, which is known as the Black Mountain. The Black Mountains 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 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) at the eastern edge of the massif. The range includes the highest public road in Wales at Gospel Pass, and the highest point in southern England ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end o ...
