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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newlands Valley
The Newlands Valley is in the Lake District National Park in Cumbria, England. It is regarded as one of the most picturesque and quiet valleys in the national park, even though it is situated very close to the popular tourist town of Keswick and the busy A66 road. The valley forms part of the civil parish of Above Derwent, within the Borough of Allerdale. Early history The earliest signs of human settlement in the valley have been found at Ullock, where evidence of a Bronze Age burial site has been found. The remains of a Celtic workshop were also found at Portinscale. Viking herdsmen arrived in Cumbria after 800 AD. Many of the present day place names in the Newlands valley have their origins from these early Norse settlers. The valley area was originally called Rogersat or Rogersyde which was derived from the Old Norse “Roger-Saetr”, which translates as ''Summer pasture belonging to Roger''. The present day Newlands valley settlements of Keskadale, Skelgill, Birk Rigg, H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be distingui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derwentwater
Derwentwater, or Derwent Water, is one of the principal bodies of water in the Lake District National Park in north west England. It lies wholly within the Borough of Allerdale, in the county of Cumbria. The lake occupies part of Borrowdale and lies immediately south of the town of Keswick. It is both fed and drained by the River Derwent. It measures approximately long by wide and is some deep. There are several islands within the lake, one of which is inhabited. Derwentwater is a place of considerable scenic value. It is surrounded by hills (known locally as fells), and many of the slopes facing Derwentwater are extensively wooded. A regular passenger launch operates on the lake, taking passengers between various landing stages. There are seven lakeside marinas, the most popular stops being Keswick, Portinscale and the Lodore Falls, from which boats may be hired. Recreational walking is a major tourist activity in the area and there is an extensive network of footpa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helvellyn Range
The Helvellyn range is the name given to a part of the Eastern Fells in the English Lake District, "fell" being the local word for "hill". The name comes from Helvellyn, the highest summit of the group. The Helvellyn range forms a ridge extending for about 10 km, at no point dropping below 600 m. The ridge runs in a north–south direction, with Patterdale on the eastern side and the Thirlmere valley to the west. The village of Threlkeld lies directly to the north, below the northernmost point on the ridge, Clough Head. Generally, the slopes above Thirlmere are steep and grassy, whilst the Patterdale side exhibits rockier features, due to cirque glaciation on the north east side of the ridge. List of peaks The majority of the peaks in the range lie directly on the north–south axis, although there are some outliers on the eastern side of the ridge. *Clough Head (726 m) *Great Dodd (856 m) *Watson's Dodd (789 m) *Stybarrow Dodd (843 m) ** Gree ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greywacke
Greywacke or graywacke (German ''grauwacke'', signifying a grey, earthy rock) is a variety of sandstone generally characterized by its hardness, dark color, and poorly sorted angular grains of quartz, feldspar, and small rock fragments or lithic fragments set in a compact, clay-fine matrix. It is a texturally immature sedimentary rock generally found in Paleozoic strata. The larger grains can be sand- to gravel-sized, and matrix materials generally constitute more than 15% of the rock by volume. The term "greywacke" can be confusing, since it can refer to either the immature (rock fragment) aspect of the rock or its fine-grained (clay) component. The origin of greywacke was unknown until turbidity currents and turbidites were understood, since, according to the normal laws of sedimentation, gravel, sand and mud should not be laid down together. Geologists now attribute its formation to submarine avalanches or strong turbidity currents. These actions churn sediment and cause m ...

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 percussio ...

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 define ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
