Birks (Lake District)
Birks is a fell in the English Lake District situated two kilometres south west of the village of Patterdale in the Eastern Fells. The fells summit sits on a shoulder of the north east ridge of the higher and better known fell of St Sunday Crag, by which it is dominated, walkers often pass over the top of Birks either climbing or descending from the larger fell. The fell's name means a place where Birch trees predominate. Topography Birks reaches a height of 622 meters (2,041 feet) and is characterised by a grassy summit ridge which has precipitous craggy slopes to the north and west which fall away to the valley of Grisedale, its southern flank is steep and grassy and ends in the valley of Deepdale and to the north east the main ridge descends towards Patterdale over Black Crag and through Glenamara Park. Birks is regarded by guide book writers as an unspectacular fell, it has 19 meters of prominence from St Sunday Crag and therefore qualifies as a Nuttall, while Alfred Wa ...

St Sunday Crag
St Sunday Crag is a fell in the English Lake District, part of the Fairfield group in the Eastern Fells. It is a prominent feature in the Patterdale skyline, with a distinctive rounded shape. Indeed, it figures so finely in views from the upper reach of the lake that it is sometimes referred to as ‘the Ullswater Fell’.Richards, Mark: ''Near Eastern Fells'': Collins (2003): Topography St Sunday Crag is the high point on the north-eastern ridge of Fairfield, which runs for two miles before descending to the valley floor behind Patterdale village. From the flat Fairfield summit a rough slope descends over the subsidiary top of Cofa Pike to the col at Deepdale Hause at ''c''680 m (2,200 ft). This is a narrow point on the ridge, deeply scarred by pedestrian traffic. The ground now rises again to St Sunday Crag, soaring above the fells on either side. Beyond the summit there is a swift drop to the lower plateau of Birks and beyond this is the further satellite of Arnis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Nuttalls In England
This is a list of Nuttall mountains in England and Wales by height. Nuttalls are defined as peaks above in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above ; a mix of imperial and metric thresholds. The Nuttall classification was suggested by Anne and John Nuttall in their 1990 two–volume book, "The Mountains of England and Wales". The list was updated with subsequent revised editions by the Nuttalls. Because of the prominence threshold of only , the list is subject to ongoing revisions. In response, Alan Dawson introduced the Hewitts, with a higher prominence threshold of . This was the prominence threshold that the UIAA set down in 1994 for an "independent" peak. In 2010, Dawson replaced his Hewitts with the fully "metric" Simms, consisting of a height threshold of , and a prominence threshold of . However, both the Nuttall and Hewitt classifications have become popular with peak baggers, and both remain in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fells Of The Lake District
A fell (from Old Norse ''fell'', ''fjall'', "mountain"Falk and Torp (2006:161).) is a high and barren landscape feature, such as a mountain or moor-covered hill. The term is most often employed in Fennoscandia, Iceland, the Isle of Man, parts of northern England, and Scotland. Etymology The English word "fell" comes from Old Norse ''fell'' and ''fjall'' (both forms existed). It is cognate with Danish ''fjeld'', Faroese ''fjall'' and ''fjøll'', Icelandic ''fjall'' and ''fell'', Norwegian ''fjell'' with dialects ''fjøll'', ''fjødd'', ''fjedd'', ''fjedl'', ''fjill'', ''fil(l)'', and ''fel'', and Swedish ''fjäll'', all referring to mountains rising above the alpine tree line.Bjorvand and Lindeman (2007:270–271). British Isles In northern England, especially in the Lake District and in the Pennine Dales, the word "fell" originally referred to an area of uncultivated high ground used as common grazing usually on common land and above the timberline.

Ullswater
Ullswater is the second largest lake in the English Lake District, being about long and wide, with a maximum depth a little over . It was scooped out by a glacier in the Last Ice Age. Geography It is a typical Lake District "ribbon lake", formed after the last ice age by a glacier scooping out the valley floor, which then filled with meltwater. Ullswater was formed by three glaciers. Surrounding hills give it the shape of an extenuated "Z" with three segments or reaches winding through them. For much of its length, Ullswater formed the border between the historic counties of Cumberland and Westmorland. Etymology The origin of the name Ullswater is uncertain. Whaley suggests "Ulf's lake", from Old Norse personal name Ulfr plus Middle English water, influenced in usage by the Old Norse ''vatn'' (water or lake). ''Ulfr'' is also the Old Norse noun meaning wolf, and Hutchinson thought that the name might refer to the lake as a resort of wolves, or to its elbow-shaped bend (citi ...

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 ...

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] |
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] |
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 W ...

Alfred Wainwright
Alfred Wainwright MBE (17 January 1907 – 20 January 1991), who preferred to be known as A. Wainwright or A.W., was a British fellwalker, guidebook author and illustrator. His seven-volume '' Pictorial Guide to the Lakeland Fells'', published between 1955 and 1966 and consisting entirely of reproductions of his manuscript, has become the standard reference work to 214 of the fells of the English Lake District. Among his 40-odd other books is the first guide to the Coast to Coast Walk, a 182-mile long-distance footpath devised by Wainwright which remains popular today. Life Alfred Wainwright was born in Blackburn, Lancashire, into a family which was relatively poor, mostly because of his stonemason father's alcoholism. He did very well at school (first in nearly every subject) although he left at the age of 13. While most of his classmates were obliged to find employment in the local mills, Wainwright started work as an office boy in Blackburn Borough Engineer's Departme ...

Topographic Prominence
In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's ''key col'' (the highest col surrounding the peak) is a unique point on this contour line and the ''parent peak'' is some higher mountain, selected according to various criteria. Definitions The prominence of a peak may be defined as the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following way: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''key saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the pro ...
