Hopegill Head
Hopegill Head is a fell in the English Lake District in Cumbria. It is located nine kilometres (5½ miles) west of the town of Keswick and is well seen from the B5292 road which crosses the Whinlatter Pass. Topography Hopegill Head is the middle fell of three fells on a ridge that starts at Braithwaite and goes west for eight kilometres to conclude at the northern end of Crummock Water. The other two fells on the ridge are Grisedale Pike and Whiteside. The fell is often referred to locally as Hobcarton Pike as it stands at the head of Hobcarton Gill. However, the Ordnance Survey have officially named the fell Hopegill Head on maps after Hope Gill, which is another valley that goes north-west from the summit. Hopegill Head reaches a height of 770 metres (2526 feet) and has two subsidiary summits, Ladyside Pike (703 metres / 2306 feet) and Sand Hill (756 metres / 2480 feet) both of which have Nuttall status. Hopegill Head’s most striking feature is the 130-metre-high (41 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whiteside (Lake District)
Whiteside is a fell in the north-western area of the English Lake District. It stands at the western end of the Grisedale Pike- Hopegill Head ridge overlooking Crummock Water. Topography The North Western Fells occupy the area between the rivers Derwent and Cocker, a broadly oval swathe of hilly country, elongated on a north-south axis. Two roads cross from east to west, dividing the fells into three convenient groups. The central sector, rising between Whinlatter Pass and Newlands Pass, includes Whiteside. The high ground in this group of fells is formed by a series of ridges in the form of the letter 'H' lying on one side. The northern ridge is formed by Whiteside, Hopegill Head and Grisedale Pike, while the Grasmoor to Causey Pike ridge runs parallel to the south. The bridge between the two is the pass of Coledale Hause. This stands at the head of two valleys, Coledale descending eastward and Gasgale Gill flowing west. Whiteside forms a shallow crescent, concave to the ... [...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] |
Eel Crag
Crag Hill is a mountain in the North Western part of the English Lake District. It was formerly known as Eel Crag; however, the Ordnance Survey now marks Eel Crag as referring to the northern crags of the fell. It is not to be confused with another Crag Hill lying on the border of North Yorkshire. It overlooks the valleys of Rannerdale on the west, and Coledale on the east. It is the second highest fell in the area of high ground between the passes of Whinlatter and Newlands, second to Grasmoor. It is 839 m (2,753 feet) high, and has a relative height of 117 m. Topography The North Western Fells occupy the area between the rivers Derwent and Cocker, a broadly oval swathe of hilly country, elongated on a north-south axis. Two roads cross from east to west, dividing the fells into three convenient groups. The central sector, rising between Whinlatter and Newlands passes, includes Crag Hill.

Coledale Horseshoe
The Coledale horseshoe, or Coledale Round, is a semi-circle of fells surrounding Coledale in the Lake District, England. It provides excellent ridge-walking over the fells. Due to the topography, there are multiple variants of the horseshoe with the option for walkers to add in a variety of extra peaks if they choose. Fell structure A horseshoe of high summits surrounds Coledale, from Grisedale Pike in the north, round through Hopegill Head, down to the pass of Coledale Hause, and then up to Eel Crag (known as 'Cragg Hill' on Ordnance Survey maps) and Sail. To the south the ridge splits into two, with Scar Crags and Causey Pike on the outer ridge and Outerside and Barrow forming what Wainwright called "a lower and parallel ridge like an inner balcony". The Rounds There is no definitive version of the round. The Coledale Horseshoe fell running race takes in Grisedale Pike before dropping down to Coledale Hause, and then covers Eel Crag, Sail, Outerside and Barrow, which is the ...

Coledale Hause
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.

Lorton, Cumbria
Lorton, a parish in the district of Allerdale of the English county of Cumbria, consists of two adjacent villages: Low Lorton and High Lorton. Both nestle at the northern end of the Vale of Lorton, surrounded by fells such as Grasmoor, Hopegill Head and Whiteside. They are about 4 miles (6.5 km) from Cockermouth, which gives access to the main A66 road. Other nearby places include Loweswater and Brigham. Tourism Lorton is relatively untouched by tourism, but many pass through on the way to the Buttermere valley. There are several hill walks available. For instance, Hopegill Head can be climbed from High Lorton and Fellbarrow from Low Lorton. Of interest are the 12th-century St Cuthbert's Church and the 1663 pele tower, but the latter is closed to the public. Lorton's ancient Yew Tree is the subject of a poem by Wordsworth. The Whinlatter Pass road connects Lorton with Braithwaite. The main road passing through Lorton links Cockermouth with Buttermere and Loweswater. The ...

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] |
Greywacke
Greywacke or graywacke (German ''grauwacke'', signifying a grey, earthy rock) is a variety of sandstone generally characterized by its hardness, dark color, and poorly sorted angular grains of quartz, feldspar, and small rock fragments or lithic fragments set in a compact, clay-fine matrix. It is a texturally immature sedimentary rock generally found in Paleozoic strata. The larger grains can be sand- to gravel-sized, and matrix materials generally constitute more than 15% of the rock by volume. The term "greywacke" can be confusing, since it can refer to either the immature (rock fragment) aspect of the rock or its fine-grained (clay) component. The origin of greywacke was unknown until turbidity currents and turbidites were understood, since, according to the normal laws of sedimentation, gravel, sand and mud should not be laid down together. Geologists now attribute its formation to submarine avalanches or strong turbidity currents. These actions churn sediment and cause mi ...

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] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lychnis
''Silene'' is a genus of flowering plants in the family Caryophyllaceae. Containing nearly 900 species, it is the largest genus in the family. Common names include campion and catchfly. Many ''Silene'' species are widely distributed, particularly in the northern hemisphere. Scientific history Members of this genus have been the subject of research by preeminent plant ecologists, evolutionary biologists, and geneticists, including Charles Darwin, Gregor Mendel, Carl Correns, Herbert G. Baker, and Janis Antonovics. Many ''Silene'' species continue to be widely used to study systems, particularly in the fields of ecology and evolutionary biology.Bernasconi et al. 2009. Silene as a model system in ecology and evolution. Heredity. 103:5-14. PMI19367316/ref> The genus has been used as a model for understanding the genetics of sex determination for over a century. ''Silene'' species commonly contain a mixture of hermaphroditic and female (or male-sterile) individuals (gynodioecy), and ...

National Trust For Places Of Historic Interest Or Natural Beauty
The National Trust, formally the National Trust for Places of Historic Interest or Natural Beauty, is a charity and membership organisation for heritage conservation in England, Wales and Northern Ireland. In Scotland, there is a separate and independent National Trust for Scotland. The Trust was founded in 1895 by Octavia Hill, Sir Robert Hunter and Hardwicke Rawnsley to "promote the permanent preservation for the benefit of the Nation of lands and tenements (including buildings) of beauty or historic interest". It was given statutory powers, starting with the National Trust Act 1907. Historically, the Trust acquired land by gift and sometimes by public subscription and appeal, but after World War II the loss of country houses resulted in many such properties being acquired either by gift from the former owners or through the National Land Fund. Country houses and estates still make up a significant part of its holdings, but it is also known for its protection of wild lands ...
