Dove Crag
Dove Crag is a fell in the English Lake District. Situated in the Eastern Fells of the national park, seven kilometres south-south-west of Glenridding, it reaches a height of 792 metres (2,598 feet). The fell is often climbed as part of the Fairfield horseshoe walk but a direct ascent from Patterdale is required to show the fell's full potential, displaying the impressive crags just to the north east of the summit. The highest point was originally unnamed on maps, being just a minor top, but over the years the summit has adopted the name of Dove Crag by mutual accord.. Wainwright's Pictorial Guides One of Dove Crag's claims to fame is that it was the first chapter ever written by Alfred Wainwright for his Pictorial Guide to the Lakeland Fells. He wrote the Dove Crag chapter on 9 November 1952 as he started Book One, after ascending the fell from Ambleside in the previous weeks, making notes and taking photographs. It would take Wainwright a further 14 years to finish the complet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hart Crag
Hart Crag is a fell in the English Lake District, being one of the Fairfield group of hills in the Eastern Fells. Topography The fell stands on the ridge running south east from Fairfield to Dove Crag, at the point where a long subsidiary spur sweeps off to the north east. This is Hartsop above How and, although in reality part of Hart Crag, was treated as a separate fell by Alfred Wainwright in his ''Pictorial Guide to the Lakeland Fells''. That convention is also followed here. Being at the meeting point of three ridges, Hart Crag also has a share in three valleys. Despite forming a part of the headwall in each case, the fell is not the true head of any of them. West of the summit runs the long and unfrequented valley of Rydal Beck. This flows almost due south for 3 miles, finally emptying into the River Rothay at Rydal village. The slopes of Rydal Head below Hart Crag are steep, but reasonably free of outcropping rock. To the north of Hart Crag is Link Cove. This is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kirkstone Pass
Kirkstone Pass is a mountain pass in the English Lake District, in the county of Cumbria. It is at an altitude of . It is the District's highest pass traversed by road, the A592 road between Ambleside in Rothay Valley and Patterdale in Ullswater Valley. The road gradient approaches 1 in 4. The picturesque view down into Patterdale has Brothers Water as its focal point. The Kirkstone Pass Inn stands close to the summit. Once a vital coaching inn, it now caters primarily for tourists. It is the third-highest public house in England. Slate quarrying Lead and copper ore mining and slate mining has spanned centuries. Petts Quarry worked by Kirkstone Green Slate Company is just to the Ambleside side of the summit. Nearby is Hartsop Hall lead mine. Caudale slate mine is a few miles further down, on the Ullswater side, and was last worked at the beginning of the 20th century; all its adits are now blocked. Name The name of the pass comes from a prominent stone, the Kirkst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Bouldering
Bouldering is a form of free climbing that is performed on small rock formations or artificial rock walls without the use of ropes or harnesses. While bouldering can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and to provide a firmer grip, and bouldering mats to prevent injuries from falls. Unlike free solo climbing, which is also performed without ropes, bouldering problems (the sequence of moves that a climber performs to complete the climb) are usually less than tall. Traverses, which are a form of boulder problem, require the climber to climb horizontally from one end to another. Artificial climbing walls allow boulderers to climb indoors in areas without natural boulders. In addition, bouldering competitions take place in both indoor and outdoor settings. The sport was originally a method of training for roped climbs and mountaineering, so climbers could practice specific moves at a safe di ...

Climbing
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Ca ...

British Geological Survey
The British Geological Survey (BGS) is a partly publicly funded body which aims to advance 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, Cardiff and London. The current motto of the BGS is: ''Gateway to the Earth''. History and previous names The Geological Survey was founded in 1835 by the Board of Ordnance as the Ordnance Geological Survey, under Henry De la Beche. This was the world's first national 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. On 1 January 1984, the institute was renamed the British Geological Survey (and often referred to as the BGS), a name still carried today. Competenc ...

Breccia
Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its source area, since other ... [...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 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) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 65% of ... [...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] |
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 ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Pike
Low Pike is a small fell in the English Lake District. It has a modest height of 508 m (1,667 ft) and is situated three kilometres north of Ambleside. Low Pike is well seen from the streets of the town as the first prominent fell on the ridge which continues northwards for a further four kilometres to Fairfield. This ridge is part of the Fairfield horseshoe walk and Low Pike is most commonly ascended as part of this. Topography Despite its modest height, Alfred Wainwright gave Low Pike a separate chapter in his ''Pictorial Guide to the Lakeland Fells'' because "it is sufficiently elevated above the deep valleys of Scandale and Rydale to give an impression of loftiness which exaggerates its modest altitude." Bill Birkett also mentions the fell in his “Complete Lakeland Fells”, but its altitude is not sufficient to be noted on any other mountain lists. Geology The crest of the ridge consists of the dacitic welded lapilli-tuff of the Lincomb Tarns Formation. And ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Pike (Scandale)
High Pike is a fell in the English Lake District, located five kilometres north of Ambleside. Situated in the Eastern Fells, it can be confused with another Lake District High Pike in the Northern Fells. High Pike reaches a height of . It is sometimes referred to as Scandale Fell, although this name really only applies to the high ground at the head of Scandale. Topography When viewed from the south around High Sweden bridge near Ambleside, High Pike has the look of a remote peak standing alone with cliffs falling away from the summit on its eastern side. However, in reality it is just a slight rise on the long southern ridge of Dove Crag with only about five metres of prominence which prevents it even qualifying as a “Nuttall”; nevertheless both Alfred Wainwright and Bill Birkett mention the fell in their books on the Lakeland Fells. Geology The crest of the ridge consists of the volcaniclastic laminated claystone and siltstone of the Esk Pike Formation. Beneath is the ...
