Walla Crag
Walla Crag is a fell in the English Lake District, near Keswick. The fell is a short walk from Keswick and overlooks Derwentwater. Topography The crag is the terminal cliff on a short ridge running north west from Bleaberry Fell, dropping about 400 ft from the plateau above. Below this are further steep slopes before the gradient slackens on the shore of Derwentwater. The face is heavily wooded — mainly with conifers — almost to the top. The trees continue down through Great Wood to the lake. Walla Crag has one major breach, Lady's Rake. The summit lies a little way back from the brink, the smooth heather-clad hinterland then dropping to the broad depression of Low Moss. Beyond here the ground rises again to Bleaberry Fell. The southern boundary of the fell is formed by Cat Gill, which flows west from Loss Moss to the lake. The gill separates Walla Crag from the neighbouring Falcon Crag, popular with rock climbers. Brockle Beck flows north from Low Moss, before turnin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hause Gate
Hill passes of the Lake District were originally used by people in one valley travelling to another nearby without having to go many miles around a steep ridge of intervening hills. Historically, in the Lake District of northwest England, travel on foot or by pony was difficult because of the region's steep-sided valleys so tracks across the ridges were created taking the easiest route over passes – often, but not always, via a col. Since Roman times long-distance travel had tended to be along ridges. From the 19th century these passes and ridge routes were brought back into use when recreational hill walking become popular. Forty hill passes within the Lake District National Park are listed here, using criteria for selecting the major routes. Background The Lake District National Park was created in 1951 covering an area of over and, although its population is only 42,000, over 10 million visitors arrive each year, mostly attracted by the lakes and fells.

Plagioclase
Plagioclase is a series of 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 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 crystal lattice structure. Plagioclase in hand samples is often identified by its polysynthetic crystal twinning or 'record-groove' effect. Plagioclase is a major constituent mineral in the Earth's crust, and is consequently an important diagnostic tool in petrology for identifying the composition, origin and evolution of igneous rocks. Plagioclase is also a major constituent of rock in the highlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summit Of Walla Crag
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary. ...

Pictorial Guide To The Lakeland Fells
''A Pictorial Guide to the Lakeland Fells'' is a series of seven books by A. Wainwright, detailing the fells (the local word for hills and mountains) of the Lake District in northwest England. Written over a period of 13 years from 1952, they consist entirely of reproductions of Wainwright's manuscript, hand-produced in pen and ink with no typeset material. The series has been in print almost continuously since it was first published between 1955 and 1966, with more than 2 million copies sold. It is still regarded by many walkers as the definitive guide to the Lakeland mountains. The 214 fells described in the seven volumes have become known as the Wainwrights. the LDWA register of those who have climbed all the fells listed 674 names. The Wainwright Society maintains a "register of current Society members who have climbed all 214 fells". First editions The first five books were originally published by Wainwright's friend, Henry Marshall, Chief Librarian of Kendal and West ...

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

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 ...

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 moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often 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. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...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 the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bleaberry Fell
Bleaberry Fell is a fell in the Lake District in Cumbria, England, with a height of 590 metres (1,936 feet). It stands on the main watershed between Borrowdale and Thirlmere and can be climbed from either flank. Walla Crag is a subsidiary top of Bleaberry Fell. Topography Situated in the central area of the national park, four kilometres ( miles) south of Keswick, Bleaberry Fell is the northernmost top on the ridge that separates the valleys containing the lakes of Derwent Water (Borrowdale) and Thirlmere. This ridge, which also contains the fells of High Seat and High Tove, is notoriously boggy underfoot, but Bleaberry Fell is mostly dry and the heather-covered summit gives an excellent all-round vista. To the east the fell has the rock faces of Iron Crag and Goat Crags as it falls away towards the Thirlmere valley. Ascents The fell is usually climbed from the car park in Great Wood in Borrowdale, firstly ascending Walla Crag via Cat Gill and then continuing south-e ...
