Little Hart Crag
Little Hart Crag is a fell in the Lake District area of England. It stands at the head of Scandale, six kilometres north of Ambleside, at a height of 637 metres (2090 feet). It is an eastern outlier of Dove Crag in the Eastern Fells, although it does have 34 metres of prominence from that fell making it both a Hewitt and a Nuttall fell. It is frequently climbed as part of the Dovedale horseshoe, an 11 kilometre walk over the neighbouring fells of Hartsop above How, Hart Crag, Dove Crag and High Hartsop Dodd, starting and finishing at Brothers Water. Topography Little Hart Crag is composed of grassy slopes on its eastern slopes above the Scandale Pass, with the tiny Scandale Tarn tucked in a hollow in the hill. To the east it drops steeply into Caiston Glen. On its west side it is connected to Dove Crag by the boggy hollow of Bakestone Moss and to the north east a ridge falls away towards Patterdale going over High Hartsop Dodd before dropping steeply to the valley.

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] |
High Hartsop Dodd
High Hartsop Dodd is a fell in the English Lake District, an outlier of the Fairfield group in the Eastern Fells. It stands above Kirkstone Pass on the road from Ullswater to Ambleside. Topography High Hartsop Dodd is properly the north eastern ridge of Little Hart Crag, 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 it having ''"the appearance of an isolated mountain with a peaked summit and steep sides, a very shapely pyramid rising from the green fields."'' Alfred Wainwright: '' A Pictorial Guide to the Lakeland Fells'', Book 1: There are three Dodds when viewed from Hartsop, the others being (Low) Hartsop Dodd and Middle Dodd. The names refer to their position in the valley rather than their height. All three present an imposing pyramidal profile when seen from below, totally obscuring their parent fells. Similarly, all three appear entire ... [...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.

Fairfield (Lake District)
Fairfield is a fell in the English Lake District. It is the highest of a group of hills in the Eastern Fells, standing to the south of the Helvellyn range. Topography There is a marked contrast between the character of the northern and southern flanks of Fairfield. Alfred Wainwright in his influential ''Pictorial Guide to the Lakeland Fells'' wrote that ''"From the south it appears as a great horseshoe of grassy slopes below a consistently high skyline...but lacking those dramatic qualities that appeal most to the lover of hills. But on the north side the Fairfield range is magnificent: here are dark precipices, long fans of scree...desolate combes and deep valleys."''Alfred Wainwright:''A Pictorial Guide to the Lakeland Fells'', Book 1: Fairfield has connecting ridges to several other fells and in plan view can be likened to a bow-tie. The top has an east–west axis with ridges running out north and south from each end. The two southern arms make up the popular walk, the Fa ...

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] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

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 ...

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 related to ... [...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 ...
