Middle Dodd
Middle Dodd is a fell in the English Lake District, an outlier of the Helvellyn range in the Eastern Fells. It stands above Kirkstone Pass on the road from Ullswater to Ambleside. Topography Middle Dodd is properly the northern ridge of Red Screes, but was given the status of a separate fell by Alfred Wainwright in his ''Pictorial Guide to the Lakeland Fells'' and that convention is followed here. His decision was based on its being "…the most striking object in a fine array of mountain scenery…"Alfred Wainwright: ''A Pictorial Guide to the Lakeland Fells'', Book 1: The fell is named as the middle one of three Dodds when viewed from Hartsop, the others being (Low) Hartsop Dodd and High Hartsop Dodd. The names thus refer to position in the valley rather than height. All three present an imposing pyramidal profile when seen from below, totally obscuring their parent fells. Similarly, all three appear entirely derivative when viewed from other angles. From the wide summit of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Screes
Red Screes is a fell in the English Lake District, situated between the villages of Patterdale and Ambleside. It may be considered an outlier of the Fairfield group in the Eastern Fells, but is separated from its neighbours by low cols. This gives Red Screes an independence which is reflected in its prominence. Topography Red Screes is a ridge of high ground which runs for nearly 7 km in a north north-easterly direction from the town of Ambleside, and reaches a maximum height of 776 m. This ridge narrows at either end, giving it the shape of a long upturned boat. It is separated from neighbouring fells by Scandale Pass to the west (c.516 m) and Kirkstone Pass to the east (455 m). These two low cols mean that Red Screes is seen as an independent fell when viewed from the south of the Lake District. They also give the fell sufficient prominence to be classified as a Marilyn. There are two minor subsidiary tops: Snarker Pike (644 m) on the south ridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartsop Dodd
Hartsop Dodd is a fell in the English Lake District, standing to the south east of Brothers Water. It is a subsidiary top on the north ridge of Caudale Moor, but was given separate fell status by Wainwright in his ''Pictorial Guide to the Lakeland Fells''.Alfred Wainwright:''A Pictorial Guide to the Lakeland Fells'', Book 2: That convention is followed here. Topography A broad grassy ridge descends gently from Caudale Moor, running north from the summit plateau and topped by a stone wall. After about half a mile it narrows considerably and turns north-west for the same distance again. Finally it throws up a small grassy dome which is the summit of Hartsop Dodd. After this the ridge drops quickly to valley level between Hartsop village and Brothers Water. The western flank of the ridge stands above the high valley of Caudale, which is a feeder of Kirkstone Beck and Brothers Water. On the eastern side is Pasture Bottom, the valley of Pasture Beck. This stream joins the outflow ... [...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] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...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 ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...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 geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained (aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline volcanic rock, subalkaline tholeiite, tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene (augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form rhyodacite, transitions to the rhyolites. The rel ...

Brothers Water
Brothers Water is a small lake in the Hartsop valley, in the eastern region of the Lake District in England. Once called Broad Water, it lies at the northern end of Kirkstone Pass, affording views on the descent towards Patterdale. The name was changed in the 19th century after two brothers drowned there. Dorothy Wordsworth, having left William Wordsworth sitting on Cow Bridge, walked beside the lake on 16 April 1802, commented on: The lake is not among the most popular in the national park, being shallow and full of reeds. Water lilies bloom in July, providing colour. To the north-east of Brothers Water is the village of Hartsop, which has several 17th-century stone farm buildings and cottages. Some of the buildings still contain spinning-rooms where villagers would have made their own clothing, selling any surplus in the local market towns. The word Hartsop means "valley of the deer", which would have lived in the woodlands of the lower areas of the surrounding fells. A wal ...

Scandale Pass
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.
