Great End
Great End is the most northerly mountain in the Scafell chain, in the English Lake District. From the south it is simply a lump continuing this chain. From the north, however, it appears as an immense mountain, with an imposing north face rising above Sprinkling Tarn (lake). This is a popular location for wild camping, and the north face attracts many climbers. Alfred Wainwright wrote of Great End in his Pictorial Guide to the Lakeland Fells: "This is the true Lakeland of the fellwalker, the sort of terrain that calls him back time after time, the sort of memory that haunts his long winter exile. It is not the pretty places - the flowery lanes of Grasmere or Derwentwater's wooded bays - that keep him restless in his bed; it is the magnificent ones. Places like Great End..." Topography The imposing north-eastern cliffs, riven by gullies, rise some 600 ft from the Esk Hause path. Their orientation ensures that the sun rarely reaches them, the gullies often retaining sn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ill Crag
Ill Crag is a fell in the English Lake District. At , it is the fourth-highest Hewitt and Nutalls anGoogle Search "Highest Mountains In England" peak in England, after Scafell Pike, Sca Fell, and Helvellyn. Ill Crag overlooks Eskdale and has splendid views across to Bowfell and Crinkle Crags. Topography It forms part of the Scafell chain, and lies about 1 km east of Scafell Pike. Broad Crag lies immediately to the west, between Ill Crag and the Pike. Ascents Ill Crag may be climbed en route to Scafell Pike, via a path from Esk Hause, but it is commonly passed by without going to the actual summit, which is rocky making progress slow. Ill Crag's summit is a few hundred metres to the south of the path from Esk Hause to Scafell Pike Scafell Pike () is the highest and the most prominent mountain in England, at an elevation of above sea level. It is located in the Lake District National Park, in Cumbria, and is part of the Southern Fells and the Scafell massif. Scafell ...

Lapilli
Lapilli is a size classification of tephra, which is material that falls out of the air during a volcanic eruption or during some meteorite impacts. ''Lapilli'' (singular: ''lapillus'') is Latin for "little stones". By definition lapilli range from in diameter. A pyroclastic particle greater than 64 mm in diameter is known as a volcanic bomb when molten, or a volcanic block when solid. Pyroclastic material with particles less than 2 mm in diameter is referred to as volcanic ash. Formation Lapilli are spheroid-, teardrop-, dumbbell- or button-shaped droplets of molten or semi-molten lava ejected from a volcanic eruption that fall to earth while still at least partially molten. These granules are not accretionary, but instead the direct result of liquid rock cooling as it travels through the air. Lapilli tuffs are a very common form of volcanic rock typical of rhyolite, andesite and dacite pyroclastic eruptions, where thick layers of lapilli can be deposited during a ...

Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained (aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline volcanic rock, subalkaline tholeiite, tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene (augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form rhyodacite, transitions to the rhyolites. The rel ...

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] |
Claystone
Mudrocks are a class of fine-grained siliciclastic sedimentary rocks. The varying types of mudrocks include siltstone, claystone, mudstone, slate, and shale. Most of the particles of which the stone is composed are less than and are too small to study readily in the field. At first sight, the rock types appear quite similar; however, there are important differences in composition and nomenclature. There has been a great deal of disagreement involving the classification of mudrocks. A few important hurdles to their classification include the following: # Mudrocks are the least understood and among the most understudied sedimentary rocks to date. # Studying mudrock constituents is difficult due to their diminutive size and susceptibility to weathering on outcrops. # And most importantly, scientists accept more than one classification scheme. Mudrocks make up 50% of the sedimentary rocks in the geologic record and are easily the most widespread deposits on Earth. Fine sedimen ...

Volcaniclastic
Volcaniclastics are geologic materials composed of broken fragments (clasts) of volcanic rock. These encompass all clastic volcanic materials, regardless of what process fragmented the rock, how it was subsequently transported, what environment it was deposited in, or whether nonvolcanic material is mingled with the volcanic clasts. The United States Geological Survey defines volcaniclastics somewhat more narrowly, to include only rock composed of volcanic rock fragments that have been transported some distance from their place of origin. In the broad sense of the term, volcaniclastics includes pyroclastic rocks such as the Bandelier Tuff; cinder cones and other tephra deposits; the basal and capping breccia that characterize ʻaʻā lava flows; and lahars and debris flows of volcanic origin.Vincent 2000, pp.27-28 Volcaniclastics make up more of the volume of many volcanoes than do lava flows. Volcaniclastics may have contributed as much as a third of all sedimentation in the geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borrowdale
Borrowdale is a valley and civil parish in the English Lake District in the Borough of Allerdale in Cumbria, England. It lies within the historic county boundaries of Cumberland. It is sometimes referred to as ''Cumberland Borrowdale'' to distinguish it from another Borrowdale in the historic county of Westmorland. Geography The valley rises in the central Lake District, and runs north carrying the River Derwent into the lake of Derwentwater. The waters of the river have their origins over a wide area of the central massif of the Lake District north of Esk Hause and Stake Pass. These origins include drains from the northern end of Scafell, Great End, the eastern side of the Dale Head massif, the western part of the Central Fells and all the Glaramara ridge. Near Rosthwaite the side valley of Langstrath joins the main valley from Seathwaite before the combined waters negotiate the narrow gap known as the ''Jaws of Borrowdale''. Here it is flanked by the rocky crags of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scafell Pike
Scafell Pike () is the highest and the most prominent mountain in England, at an elevation of above sea level. It is located in the Lake District National Park, in Cumbria, and is part of the Southern Fells and the Scafell massif. Scafell Pike forms part of the inactive Scafells volcano. Etymology and name history The name ''Scafell'' is believed by some to derive from the Old Norse ''skalli fjall'', meaning either the fell with the shieling or the fell with the bald summit, and is first recorded in 1578 in the corrupted form ''Skallfield''. An alternative derivation is from the Old Norse "skagi", meaning a cape, headland, promontory or peninsula – so giving an etymology that aligns with Skaw in Shetland. It originally referred to Scafell, which neighbours Scafell Pike.Dorothy Wordsworth's ascent of Scafell Pike, 1818, http://www.pastpresented.ukart.com/eskdale/wordsworth1.htm What are now known as Scafell Pike, Ill Crag, and Broad Crag were collectively called either ''t ...

Seathwaite, Allerdale
Seathwaite is a small hamlet in Borrowdale valley in the Lake District of Cumbria, North West England. It is located southwest of Keswick at the end of a minor road that heads southwest from the hamlet of Seatoller, which is where the B5289 road begins its steep climb up the pass to Honister Hause on the boundary between Borrowdale civil parish and Buttermere civil parish. The nearby Seathwaite Fell takes its name from the hamlet and lies about to the south-southwest of it. The name derives from a combination of the Old Norse words ''sef'' (sedges) and ''thveit'' (clearing) and may be taken to mean "clearing in the sedges". The name, then spelled Seuthwayt, first appeared in written records in 1340. History Along the nearby Newhouse Gill, which descends from Grey Knotts, is a graphite mine which was opened after the discovery of graphite there in 1555. The extracted graphite was eventually used to supply the Derwent Cumberland Pencil Company factory in Keswick. The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Gable
Great Gable is a mountain in the Lake District, United Kingdom. It is named after its appearance as a pyramid from Wasdale, though it is dome-shaped from most other directions. It is one of the most popular of the Lakeland fells, and there are many different routes to the summit. Great Gable is linked by the high pass of Windy Gap to its smaller sister hill, Green Gable, and by the lower pass of Beck Head to its western neighbour, Kirk Fell. Topography The Western Fells occupy a triangular sector of the Lake District, bordered by the River Cocker to the north east and Wasdale to the south east. Westwards, the hills diminish toward the coastal plain of Cumbria. At the central hub of the high country are Great Gable and its satellites, while two principal ridges fan out on either flank of Ennerdale, the western fells forming a horseshoe around this valley.Alfred Wainwright: ''A Pictorial Guide to the Lakeland Fells, Volume 7 The Western Fells'': Westmorland Gazette (1966): Gr ...
