Grisedale Pike
Grisedale Pike is a fell in the Lake District, Cumbria, England, situated west of the town of Keswick in the north-western sector of the national park. At a height of 791 m (2593 feet) it is the 40th-highest Wainwright in the Lake District; it also qualifies as a Hewitt, Marilyn and Nuttall. Grisedale Pike presents a striking appearance when viewed from the east, particularly from the vicinity of Keswick. It possesses two subsidiary summits: one unnamed (usually referred to as 'subsidiary summit', situated above Hobcarton Crag); the other Hobcarton End. Topography Grisedale Pike is a large fell throwing down three long ridges to the valley floors and two shorter ones that link to the adjoining fell of Hopegill Head and the strategically important Coledale Hause which links the fell to the rest of the Coledale Fells. It is bounded to the south by the 2½-mile (4-kilometre) valley of Coledale and to the north by the Whinlatter Pass which carries the B5292 ...

Hopegill Head
Hopegill Head is a fell in the English Lake District in Cumbria. It is located nine kilometres (5½ miles) west of the town of Keswick and is well seen from the B5292 road which crosses the Whinlatter Pass. Topography Hopegill Head is the middle fell of three fells on a ridge that starts at Braithwaite and goes west for eight kilometres to conclude at the northern end of Crummock Water. The other two fells on the ridge are Grisedale Pike and Whiteside. The fell is often referred to locally as Hobcarton Pike as it stands at the head of Hobcarton Gill. However, the Ordnance Survey have officially named the fell Hopegill Head on maps after Hope Gill, which is another valley that goes north-west from the summit. Hopegill Head reaches a height of 770 metres (2526 feet) and has two subsidiary summits, Ladyside Pike (703 metres / 2306 feet) and Sand Hill (756 metres / 2480 feet) both of which have Nuttall status. Hopegill Head’s most striking feature is the 130-metre-high (41 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrow (Lake District)
Barrow is small fell in the English Lake District in the county of Cumbria which reaches a height of 455 metres (1,494 feet). It is in the Newlands Valley 2.5 miles (4 km) south-west of Keswick. Although comparatively small in height, Barrow commands an all-round view, with the vales of Keswick and Newlands being visible. The name of the fell originates from the Anglo Saxon language meaning a hill or long ridge. Topography Barrow is a slender ridge climbing south-west from Braithwaite. At the summit it turns due west across the depression of Barrow Door, diverted by the valley of Stonycroft Gill. Beyond the col are Stile End and Outerside. The valley of Coledale lies to the north-west and Newlands Beck forms the eastern boundary. Ascents Ascents of the fell are usually started from either the Newlands Valley or Braithwaite, both providing a short ramble which can be combined with the adjoining higher fell of Outerside. The climb from Newlands starts at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whinlatter Pass
The Whinlatter Pass is a mountain pass in the English Lake District. It is located on the B5292 road linking Braithwaite, to the west of Keswick, with High Lorton to the south of Cockermouth. To the north the pass is flanked by Whinlatter fell, while to the south the Whiteside, Hopegill Head and Grisedale Pike fells borders the pass. From the top of the pass, paths climb Whinlatter and Grisedale Pike. There is also a Forestry Commission tourist centre there. The Whinlatter Pass is one of three passes that link the tourist area around Keswick, including Derwent Water and Borrowdale, with the valley of the River Cocker, including the lakes of Buttermere, Crummock Water and Loweswater. From north to south these passes are the Whinlatter Pass, the Newlands Pass, and the Honister Pass. The Whinlatter Pass can be icy in winter, but it is a less severe route than the other two passes. The Pass was used for the first King of the Mountains climb on the second stage of the 2016 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eel Crag
Crag Hill is a mountain in the North Western part of the English Lake District. It was formerly known as Eel Crag; however, the Ordnance Survey now marks Eel Crag as referring to the northern crags of the fell. It is not to be confused with another Crag Hill lying on the border of North Yorkshire. It overlooks the valleys of Rannerdale on the west, and Coledale on the east. It is the second highest fell in the area of high ground between the passes of Whinlatter and Newlands, second to Grasmoor. It is 839 m (2,753 feet) high, and has a relative height of 117 m. Topography The North Western Fells occupy the area between the rivers Derwent and Cocker, a broadly oval swathe of hilly country, elongated on a north-south axis. Two roads cross from east to west, dividing the fells into three convenient groups. The central sector, rising between Whinlatter and Newlands passes, includes Crag Hill. The highest ground in the North Western Fells is an east-west ridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry-stone Wall
Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their construction method, which is characterized by the presence of a load-bearing façade of carefully selected interlocking stones. Dry stone construction is best known in the context of stone walls, traditionally used for the boundaries of fields and churchyards, or as retaining walls for terracing, but dry stone sculptures, buildings, bridges, and other structures also exist. The term tends not to be used for the many historic styles which used precisely-shaped stone, but did not use mortar, for example the Greek temple and Inca architecture. The art of dry stone walling was inscribed in 2018 on the UNESCO representative list of the intangible cultural heritage of humanity, for dry stone walls in countries such as France, Greece, Italy, Slovenia, Cro ...

Barite
Baryte, barite or barytes ( or ) is a mineral consisting of barium sulfate ( Ba S O4). Baryte is generally white or colorless, and is the main source of the element barium. The ''baryte group'' consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO4. Names and history The radiating form, sometimes referred to as ''Bologna Stone'', attained some notoriety among alchemists for specimens found in the 17th century near Bologna by Vincenzo Casciarolo. These became phosphorescent upon being calcined. Carl Scheele determined that baryte contained a new element in 1774, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England. The American Petroleum Institute specification API 13/ISO 13500, which gover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

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] |
Force Crag Mine
Coledale is a valley in the northwestern region of the Lake District in Cumbria, England. Geography Coledale is a narrow U-shaped valley running approximately north-east towards the Derwent Valley floodplain and the village of Braithwaite at the northeastern end. The valley river Coledale Beck feeds into Newlands Beck and is fed by small streams from the valley sides and head, including Birkthwaite Beck, and Pudding Force. At the head of the valley a large rock formation is found named Force Crag, which forms a waterfall 'Low Force' as Pudding Beck passes over it. The valley is ringed by peaks popular with tourists (''Grisedale Pike'', ''Hopegill Head'', ''Coledale Hause'', ''Crag Hill'' (formerly ''Eel Crag''), ''Sail'', ''Sail Pass'', and ''Outerside'') forming a horseshoe ridge walk known as Coledale horseshoe or 'Coledale round'. Force Crag Mine Coledale's most notable feature is Force Crag Mine; the buildings, spoil heap and associated structures of which are practical ...

Skiddaw
Skiddaw is a mountain in the Lake District National Park in England. Its summit is the sixth-highest in England. It lies just north of the town of Keswick, Cumbria, and dominates the skyline in this part of the northern lakes. It is the simplest of the Lake District mountains of this height to ascend (as there is a well-trodden tourist track from a car park to the north-east of Keswick, near the summit of Latrigg) and, as such, many walking guides recommend it to the occasional walker wishing to climb a mountain. This is the first summit of the fell running challenge known as the Bob Graham Round when undertaken in a clockwise direction. The mountain lends its name to the surrounding areas of Skiddaw Forest and Back o' Skidda, and to the isolated Skiddaw House, situated to the east, formerly a shooting lodge and subsequently a youth hostel. It also provides the name for the slate derived from that region: Skiddaw slate. Skiddaw slate has been used to make tuned percussi ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
