Hard Knott
Hard Knott is a fell in the English Lake District, at the head of Eskdale. Geology Rhyolitic lava-like tuff of the Bad Step Tuff forms the summit rocks with the dacitic lapilli-tuffs of the Lincomb Tarns Formation to the north west. Border end shows outcropping plagioclase-phyric andesite lavas of the Birker Fell Formation. British Geological Survey: 1:50,000 series maps, ''England & Wales Sheet 38'': BGS (1998) Summit Hard Knott reaches a height of 549 metres (1,803 feet), the summit knoll bearing a cairn. There are other named tops on the ridge in addition to the summit, with Yew Bank to the north and Border End to the south. Hard Knott is famous for its superb view of the Scafell massif to the north, while Harter Fell dominates the vista to the south. For a fabulous view of Eskdale it is recommended that the walker visits Border End half a mile to the south of the main summit.Richards, Mark: ''Mid-Western Fells'': Collins (2004): Alfred Wainwright: ''A Pictoria ...

Hardknott Roman Fort
Hardknott Roman Fort is an archeological site, the remains of the Roman fort ''Mediobogdum'', located on the western side of the Hardknott Pass in the English county of Cumbria. The fort was built between 120 and 138 on a rocky spur, and was initially garrisoned by a detachment of the '' Cohors IV Delmatarum'' from the Dalmatian coast (in modern Croatia). It was abandoned around a decade later, then reoccupied circa 200 and remained in use for much of the next two centuries. Location and name The fort was built on a rocky spur giving a superb view over the River Esk in both upper and lower Eskdale, and protecting Hardknott Pass. At an altitude of 800 feet, it isn't the highest fort in the Roman province of Britannia, the highest fort is Epiacum or Whitley Castle, just over the border from Cumbria in Northumberland, at an altitude of 1,050 feet. The ruins have been commonly known in recent times as Hardknott Fort or Hardknott Castle, but are identified from the ''Ravenna Cos ...

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 ...

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.

Hardknott Pass
Hardknott Pass is a hill pass between Eskdale and the Duddon Valley in the Lake District National Park, Cumbria, England. The tarmac-surfaced road, which is the most direct route from the central Lake District to West Cumbria, shares the title of steepest road in England with Rosedale Chimney Bank in North Yorkshire. It has a maximum gradient of 1 in 3 (about 33%). Etymology The pass takes its name from Hard Knott which is derived from the Old Norse ''harthr'' (hard) and ''knutr'' (craggy hill). Geography A single track road runs between Eskdale in the west to the edge of the neighbouring Wrynose Pass in the east. On the western side is Harter Fell and the remains of Hardknott Roman Fort ( above sea level). The Hardknott Pass stands at a maximum elevation of . The road descends steeply at a gradient of 30% (1 in 3) into the Duddon Valley. At the eastern end of the pass is Cockley Beck farm, built in the 1860s and owned by the National Trust.

A 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 ...

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 Department. He ...

Scafell
Scafell ( or ; also spelled Sca Fell, previously Scawfell) is a mountain in the English Lake District, part of the Southern Fells. Its height of makes it the second-highest mountain in England after its neighbour Scafell Pike, from which it is separated by Mickledore col. Topography Scafell stands between Wasdale in the west and upper Eskdale to the east. The highest part of the fell is a ridge running south from Mickledore as far as Slight Side, which is counted as a separate fell by most guidebooks.Richards, Mark: ''Mid-Western Fells'': Collins (2004): Despite regarding Slight Side as a separate entity, Wainwright included the wide upland area beyond it to the south west as a part of Scafell. More modern guides have partitioned the plateau off as a further independent top, Great How. The opposing flanks of Scafell are entirely different in character. To the south, monotonous smooth slopes, stony and lacking vegetation at higher levels, run down toward Burnmoor and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cairn
A cairn is a man-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word ''cairn'' comes from the gd, càrn (plural ). Cairns have been and are used for a broad variety of purposes. In prehistoric times, they were raised as markers, as memorials and as burial monuments (some of which contained chambers). In modern times, cairns are often raised as landmarks, especially to mark the summits of mountains. Cairns are also used as trail markers. They vary in size from small stone markers to entire artificial hills, and in complexity from loose conical rock piles to elaborate megalithic structures. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. A variant is the inuksuk (plural inuksuit), used by the Inuit and other peoples of the Arctic region of North America. History Europe The building of cairns for various purposes goes back into prehistory in Eurasia, ranging in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
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] |
