Long Mountain (Powys)
Long Mountain ( cy, Cefn Digoll) is a hill straddling the boundary between Powys (Wales) and Shropshire (England) to the east of Welshpool though the summit at 408 metres (1,339 feet) at Beacon Ring () is within Wales. Long Mountain is a Marilyn (a hill with topographic prominence of at least 150 metres), having a prominence of 305 metres (1,000 feet). Geology Long Mountain is formed from a succession of sedimentary rocks dating from the Silurian period. In stratigraphic order i.e. youngest/uppermost first, these are: *Raglan Mudstone Formation (siltstone, mudstone) *Temeside Mudstone Formation (mudstone, siltstone, sandstone) *Tilestones Formation (sandstone) *Cefn Einion Formation (mudstone, siltstone, sandstone) *Knucklas Castle Formation (mudstone, siltstone, sandstone) *Bailey Hill Formation (siltstone, sandstone) (including the Cwm-yr-hob Member (mudstone, siltstone, sandstone) *Irfon Formation (mudstone, siltstone) *Gyfenni Wood Shale Formation (mudstone) *Trewern Brook ...

Transmitter Masts - Geograph
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, even ...

Glaciofluvial Deposits
Glaciofluvial deposits or Glacio-fluvial sediments consist of boulders, gravel, sand, silt and clay from ice sheets or glaciers. They are transported, sorted and deposited by streams of water. The deposits are formed beside, below or downstream from the ice. They include kames, kame terraces and eskers formed in ice contact and outwash fans and outwash plains below the ice margin. Typically the outwash sediment is carried by fast and turbulent fluvio-glacial meltwater streams, but occasionally it is carried by catastrophic outburst floods. Larger elements such as boulders and gravel are deposited nearer to the ice margin, while finer elements are carried farther, sometimes into lakes or the ocean. The sediments are sorted by fluvial processes. They differ from glacial till, which is moved and deposited by the ice of the glacier, and is unsorted. Ice-contact deposits A subglacial megaflood may cut cavities into the base of the ice. As the flood dies down, sediment is deposited ...

Iron Age
The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Stone Age (Paleolithic, Mesolithic, Neolithic) and the Bronze Age (Chalcolithic). The concept has been mostly applied to Iron Age Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World. The duration of the Iron Age varies depending on the region under consideration. It is defined by archaeological convention. The "Iron Age" begins locally when the production of iron or steel has advanced to the point where iron tools and weapons replace their bronze equivalents in common use. In the Ancient Near East, this transition took place in the wake of the Bronze Age collapse, in the 12th century BC. The technology soon spread throughout the Mediterranean Basin region and to South Asia (Iron Age in India) between the 12th and 11th century BC. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat dela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hillfort
A hillfort is a type of earthwork used as a fortified refuge or defended settlement, located to exploit a rise in elevation for defensive advantage. They are typically European and of the Bronze Age or Iron Age. Some were used in the post-Roman period. The fortification usually follows the contours of a hill and consists of one or more lines of earthworks, with stockades or defensive walls, and external ditches. Hillforts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC, and were used in many Celtic areas of central and western Europe until the Roman conquest. Nomenclature The spellings "hill fort", "hill-fort" and "hillfort" are all used in the archaeological literature. The ''Monument Type Thesaurus'' published by the Forum on Information Standards in Heritage lists ''hillfort'' as the preferred term. They all refer to an elevated site with one or more ramparts made of earth, stone and/or wood, with an external ditch. Many ...

Offa's Dyke
Offa's Dyke ( cy, Clawdd Offa) is a large linear earthwork that roughly follows the border between England and Wales. The structure is named after Offa, the Anglo-Saxon king of Mercia from AD 757 until 796, who is traditionally believed to have ordered its construction. Although its precise original purpose is debated, it delineated the border between Anglian Mercia and the Welsh kingdom of Powys. The earthwork, which was up to wide (including its flanking ditch) and high, traversed low ground, hills and rivers. Today it is protected as a scheduled monument. Some of its route is followed by the Offa's Dyke Path, a long-distance footpath that runs between Liverpool Bay in the north and the Severn Estuary in the south. Although the Dyke has conventionally been dated to the Early Middle Ages of Anglo-Saxon England, research in recent decades – using techniques such as radioactive carbon dating – has challenged the conventional historiography and theories about the earth ...

Shrewsbury And Welshpool Railway
The Shrewsbury and Welshpool Railway (S&WR) is a standard gauge railway which connects the towns of Shrewsbury and Welshpool. It opened in 1861 and the majority of the railway continues in use. History Incorporation The S&WR was incorporated in an Act of Parliament in 1856. Although initially an independent company, the line was to be operated and maintained by the London and North Western Railway (LNWR). Opening Construction under the Act began in 1859, and by 1861 the line from Shrewsbury to Minsterley was completed, and opened on 14 February 1861. Construction of the main line to Welshpool was completed later in 1861 and officially opened on 27 January 1862. Minsterley branch The Minsterley branch served the agricultural communities of the area, but its main purpose was to carry lead from the mines along the Stiperstones hills. These mines were connected to the S&WR at Pontesbury by the narrow gauge Snailbeach District Railways which opened in 1873 and closed in 1959. T ...

Breidden Hill is one of five peaks with neighbouring Moel y Golfa, which is the highest at , which is a " Marilyn", with a prominence of . The three others are Cefn y Castell (also known as Middletown Hill), Kempsters Hill and Bausley Hill (all over high) with its Iron Age galleried fortification. The five hills are sometimes collectively known as the Breidden Hills, and form a northern extension of the Long Mountain. There are remains of a British Iron Age hillfort en route which may have been the site of the last stand of Caractacus. Rodney's Pillar at the top was built by the gentlemen of Montgomeryshire w ...
