Red Pike (Wasdale)
Red Pike is a fell in the English Lake District. It is high and lies due north of Wast Water. It is often climbed as part of the Mosedale Horseshoe, a walk which also includes Pillar (Lake District), Pillar. The fell can be confused with Red Pike (Buttermere), not least because its namesake is only away, so according to Alfred Wainwright it is conventional to call it Wasdale Red Pike. 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 Cumberland. 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 Water, Ennerdale, the western fells in effect being a great horseshoe around this long wild valley.Alfred Wainwright: ''A Pictorial Guide to the Lakeland Fells, Volume 7 The Western Fells'': Westmorland Gazette (1966): Red Pike is an outl ...

List Of Wainwrights
Wainwrights are the 214 English peaks (known locally as ''fells'') described in Alfred Wainwright's seven-volume ''Pictorial Guide to the Lakeland Fells'' (1955–66). They all lie within the boundary of the Lake District National Park in Cumbria, and all but one (Castle Crag) are over in height. Over two million copies of the ''Pictorial Guides'' have been sold since their publication. In 1974, Wainwright published a supplementary volume ''The Outlying Fells of Lakeland'' (1974), which includes another 116 summits (described in 56 walks); these are the Wainwright Outlying Fells. Summiting all of the Wainwrights is a popular form of peak bagging in the Lake District, along with the List of Birketts in the Lake District, Birketts. Because both lists are based on historical books, unlike, for example, the Lists of mountains and hills in the British Isles#Munros, Munros, their constituents remain fixed, regardless of revisions to height or other metrics. There are 214 Wainwrights ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kirk Fell
Kirk Fell is a fell in the Western part of the English Lake District. It is situated between Great Gable and Pillar on the long ring of fells surrounding the valley of Ennerdale, and also stands over Wasdale to the south. However, it is separated from its two higher neighbours by the low passes of Black Sail and Beck Head, giving it a high relative height and making it a Marilyn, the thirteenth highest in the Lake District. The direct ascent up the south-western slope from Wasdale Head is exceptionally steep and the subject of an amusing drawing by Wainwright.Alfred Wainwright: ''A Pictorial Guide to the Lakeland Fells, Volume 7 The Western Fells'': Westmorland Gazette (1966): Usual ascents are by one of the aforementioned passes; alternatively one may climb Kirk Fell as part of the Mosedale Horseshoe, a walk on the fells surrounding Mosedale, a side-valley of Wasdale.

British Geological Survey
The British Geological Survey (BGS) is a partly publicly funded body which aims to advance Earth science, geoscientific knowledge of the United Kingdom landmass and its continental shelf by means of systematic surveying, monitoring and research. The BGS headquarters are in Keyworth, Nottinghamshire, England. Its other centres are located in Edinburgh, Wallingford, Oxfordshire, Wallingford, Cardiff and London. The current tagline of the BGS is: ''Understanding our Earth''. History and previous names The Geological Survey was founded in 1835 by the Board of Ordnance as the Geological Survey of Great Britain, under Directors of the British Geological Survey, directorship of Henry De la Beche. This was the world's first national Geological Survey, geological survey. It remained a branch of the Ordnance Survey for many years. In 1965, it was merged with the Geological Museum and Overseas Geological Surveys, under the name of Institute of Geological Sciences. In 1969, Beris Cox was ...

Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture (geology), texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained matrix (geology), groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent of granite. Its high silica content makes rhyolitic magma extremely viscosity, viscous. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been used extensively for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lapilli Tuff
Lapilli (: lapillus) 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'' 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 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 basal surge eruption. Most lapilli tuffs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Geology of Mars, Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) to porphyritic (coarse-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plagioclase
Plagioclase ( ) is a series of Silicate minerals#Tectosilicates, tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series. This was first shown by the German mineralogist Johann F. C. Hessel, Johann Friedrich Christian Hessel (1796–1872) in 1826. The series ranges from albite to anorthite endmembers (with respective compositions NaAlSi3O8 to CaAl2Si2O8), where sodium and calcium atoms can substitute for each other in the mineral's crystallography, crystal lattice structure. Plagioclase in hand samples is often identified by its polysynthetic crystal twinning or "phonograph record, record-groove" effect. Plagioclase is a major constituent mineral in Earth's crust and is consequently an important diagnostic tool in petrology for identifying the composition, origin and evolutio ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and Rock (geology), rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines are those formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French language, French , which in turn is derived from the Savoyard dialect, Savoyard Italian ('mound of e ...

Wastwater
Wast Water or Wastwater () is a lake located in Wasdale, a valley in the western part of the Lake District National Park, England. The lake is almost long and more than wide. It is a glacial lake, formed in a glacially 'over-deepened' valley. It is the deepest lake in England at . The surface of the lake is about above sea level, while its bottom is over below sea level. It is considered relatively oligotrophic. It is owned by the National Trust. Surroundings The head of the Wasdale Valley is surrounded by some of the highest mountains in England, including Scafell Pike, Great Gable and Lingmell. The steep slopes on the southeastern side of the lake, leading up to the summits of Whin Rigg and Illgill Head, are known as the "Wastwater Screes" or on some maps as "The Screes". These screes formed as a result of ice and weathering erosion on the rocks of the Borrowdale Volcanic Group, that form the fells to the east of the lake, towards Eskdale. They are approximately , fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Pass
A mountain pass is a navigable route through a mountain range or over a ridge. Since mountain ranges can present formidable barriers to travel, passes have played a key role in trade, war, and both Human migration, human and animal migration throughout history. At lower elevations it may be called a hill pass. A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind. Overview Mountain passes make use of a gap (landform), gap, saddle (landform), saddle, col or notch (landform), notch. A topographic saddle is analogous to the mathematical concept of a saddle surface, with a saddle point marking the minimum high point between two valleys and the lowest point along a ridge. On a topographic map, passes can be identified by contour lines with an hourglass shape, which indicates a low spot between two higher points. In the high mountains, a difference of between the summit and the mountain is defined as a mountain pass. Passes are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yewbarrow
Yewbarrow is a fell, in the English Lake District, which lies immediately north of the head of Wast Water. It is high and in shape resembles the upturned hull of a boat or a barrow. Yewbarrow is on the left in the classic view of Great Gable and Wast Water. The top of Stirrup Crag forms a second summit high, north of the main summit. The Hewitt and Nuttall lists classify the Yewbarrow North Top as a separate summit. The name is derived from the past prevalence of yew trees on the fell and its " barrow" shape. 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 Cumberland. 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 in effect being a great horseshoe around this long wild valley.Alfred Wainwright ...
