Calver Hill
Calver Hill is a fell in the Yorkshire Dales National Park in North Yorkshire, England. It is composed of limestone''"The Rivers, Mountains and Sea Coast of Yorkshire"'', John Phillips, States that Calver Hill is composed of limestone. and is situated at grid reference , near where the valleys of Swaledale and Arkengarthdale meet, the village of Reeth is located on its lower south-eastern slopes, it reaches an altitude of and is a distinguished feature in mid Swaledale. Calver Hill is an area of grouse shooting and the fell is dotted with grouse butts. Most of the drainage from the fell goes north and easterly to join the Arkle Beck in lower Arkengarthdale which eventually joins the River Swale just south of Reeth. History Evidence exits on the slopes of Calver Hill that point to use during the Neolithic Period and the Bronze Age. Finds of arrowheads, flints, and field patterns also point to possible areas of habitation. The whole area of Calver Hill is sometimes referred to ...

Fremington Edge
Fremington Edge is a long wall of crags and scree slopes that is situated to the north of the village of Reeth in Swaledale in the Yorkshire Dales, Yorkshire Dales National Park, England. Fremington Edge forms the south-eastern edge of Arkengarthdale, extending to the point where the dale meets Swaledale. Throughout its full length the Edge stays above the height of and reaches a highest point of at the northern end of the escarpment. History Fremington Edge was formed after the last Ice age when melt water from the retreating glaciers caused a landslip and exposed the rocky outcrops. Evidence of an Iron Age fort on the escarpment, and a settlement pre-date the 8th century arrival of the Anglo-Saxons. The Edge is scattered with remains of old lead and chert mines, and there are many disused shafts and spoil heaps. The chert was taken by lorry to Staffordshire for use in producing china and porcelain. A footpath and a solid Dry-stone wall, dry stone wall stretch the entire le ...

Cairn
A cairn is a man-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word ''cairn'' comes from the gd, càrn (plural ). Cairns have been and are used for a broad variety of purposes. In prehistoric times, they were raised as markers, as memorials and as burial monuments (some of which contained chambers). In modern times, cairns are often raised as landmarks, especially to mark the summits of mountains. Cairns are also used as trail markers. They vary in size from small stone markers to entire artificial hills, and in complexity from loose conical rock piles to elaborate megalithic structures. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. A variant is the inuksuk (plural inuksuit), used by the Inuit and other peoples of the Arctic region of North America. History Europe The building of cairns for various purposes goes back into prehistory in Eurasia, ranging in s ...

Arkle Town
Arkle Town is a hamlet in Arkengarthdale in the Richmondshire district of North Yorkshire, England. It is situated to the south of Langthwaite and north-west of Reeth. History "Arkel" is a Norse personal name and probably arrived with settlers during the tenth century. Formerly it had a parish church, inn and workhouse, the only evidence of these buildings that remains is a small number of gravestones at the site of the former St. Mary's Church, which was relocated further up the dale in 1816. The 1851 census counted 41 houses in Arkle Town. Governance The hamlet is within the Richmond (Yorks) parliamentary constituency, which is under the control of the Conservative Party. The current Member of Parliament, since the 2015 general election, is Rishi Sunak. Arkle Town also falls within the Lower Swaledale and Arkengarthdale ward of Richmondshire District Council and the Upper Dales Electoral Division of North Yorkshire County Council North Yorkshire County Council (N ...

Langthwaite
Langthwaite is one of the few villages in Arkengarthdale, North Yorkshire, England. It is north of Reeth and sits above sea level. It is the main settlement in the dale and is one of the most northerly settlements in the whole of Yorkshire Dales National Park. Langthwaite is one of two places in the dale that have houses clustered together closely in a traditional village set up; the rest of the settlements in the dale are populated by scattered buildings. It is home to a pub ('The Red Lion'), a shop and an unusual commissioners' church of 1818, which was one of many then built with money provided by Parliament in an attempt to counteract atheism and free thinking after the French Revolution. Langthwaite is also home to a grade II* listed hexagonal powder house, built in 1807 to store gunpowder used in the many mines dotted around the area. The 1851 census counted 48 houses in Langthwaite. The village was used for the filming of several scenes in the television series '' Al ...

Slag
Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further categorized by their precursor and processing conditions (e.g., Blast furnace (BF) slags, air-cooled blast furnace (ACBF) slag, basic oxygen furnace (BOF) slag, and electric arc furnace (EAF) slag) . Due to the large demand for these materials, slag production has also significantly increased throughout the years despite recycling (most notably in the iron and steelmaking industries) and upcycling efforts. The World Steel Association (WSA) estimates that 600 kg of by-products (~90 wt% is slags) are generated per tonne of steel produced. Composition Slag is usually a mixture of metal oxides and sili ...

Smelting
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Second, the ...

Bole Hill
A Bole hill (also spelt Bail hill) was a place where lead was formerly smelted in the open air. The bole was usually situated at or near the top of a hill where the wind was strong. Totley Bole Hill on the western fringes of Sheffield consisted of a long low wall with two shorter walls at right angles to it at each end. At the base of a bole {{convert, 20, ft, m, sing=on long were laid great trees called blocks. On these were laid ''blackwork'', partly smelted ore about half a yard thick. Then came ten or twelve trees called ''shankards''. On top of these three or four courses of ''fire trees'' were laid with fresh ore. This was ignited and burnt for about 48 hours. This smelted lead, which ran down channels provided for the purpose and was cast into sows of about 11 hundredweight. A single firing produced 16 fothers of lead (about 18 tons) from 160 loads of ore (about 40 tons) and 30 tons of wood. Much of the ore was left incompletely smelted having become ''blackwork''. ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 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 ...

Yorkshire Dales
The Yorkshire Dales is an upland area of the Pennines in the Historic counties of England, historic county of Yorkshire, England, most of it in the Yorkshire Dales National Park created in 1954. The Dales comprise river valleys and the hills rising from the Vale of York westwards to the hilltops of the Pennine Drainage divide, watershed. In Ribblesdale, Dentdale and Garsdale, the area extends westwards across the watershed, but most of the valleys drain eastwards to the Vale of York, into the River Ouse, Yorkshire, Ouse and the Humber. The extensive limestone cave systems are a major area for caving in the UK and numerous walking trails run through the hills and dales. Etymology The word ''Dale (landform), dale'', like ''dell'', is derived from the Old English word ''dæl''. It has cognates in the North Germanic languages, Nordic/Germanic languages, Germanic words for valley (''dal'', ''tal''), and occurs in valley names across Yorkshire and Northern England.
