High Seat, Lake District
High Seat is a fell in the centre of the English Lake District. Despite being below 2,000 ft it is the highest point for about 5 miles in any direction; a consequence of the curious fact that the centre of the district is lower than the surrounding parts. Topography The main watershed of the Central Fells runs north-south, with Bleaberry Fell forming the northern end of the ridge. High Seat is the next fell to the south, before the land falls to High Tove. High Seat sends out the spur of Dodd to the north west, separated from the body of the fell by Ashness Gill — a feeder of Watendlath Beck. Oddly, by the time the Gill reaches the famed viewpoint of Ashness Bridge, it has actually become Barrow Beck. The western flank here is clad in broadleaved woodland, but further south along Watendlath Beck this gives way to rock. Reecastle Crag being the principal face. The southern boundary of the fell is formed by Raise Gill on the western side of the ridge and Shoulthwait ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Raise (Langdale)
High Raise is a fell in the Central Fells of the English Lake District, not to be confused with another High Raise situated in the Far Eastern Fells. High Raise is one of the most spectacular mountains in the district; with a height of 762 metres (2,500 ft) it is the highest point in the central fells of Lakeland. High Raise is in fact commonly regarded as the most central mountain in the district and this position gives a fine viewpoint to admire the surrounding mountains and beyond. All of England's 3,000-foot (914 m) mountains (Skiddaw, Helvellyn and the Scafells) can be well seen from the summit while the more distant views include the Three Peaks in the Yorkshire Dales (37 miles / 60 km) and Morecambe Bay (25 miles / 40 km). Summit The summit itself, which is also known as High White Stones due to a smattering of grey boulders in the vicinity of the highest point, has an Ordnance Survey column and a large cairn which also doubles as a wind sh ...

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] |
High Seat, Yorkshire Dales
High Seat is a fell in the dale of Mallerstang, Cumbria. With a summit at , it is the fourth highest fell in the Yorkshire Dales after Whernside, Ingleborough and Great Shunner Fell. It is in the north-western part of the Dales, overlooking the deep trench of Mallerstang, and is usually climbed from this side. To the south-east is Hugh Seat (whose summit is marked by Lady Anne's Pillar, commemorating Sir Hugh de Morville). On the opposite (western) side of Mallerstang is the more striking (but 1 metre lower) Wild Boar Fell. It is not a Marilyn, having a relative height of 112 m, and therefore may be regarded as a subsidiary top of Great Shunner Fell, to the east. It is, however, a HuMP. Oddly enough, it is the highest point on the main England east-to-west watershed in the Dales, the three higher fells being some distance from the watershed. Three main rivers have their origins in the peat bogs here: the River Eden, the River Swale, and the River Ure. See also * H ...

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 ...

Watendlath
Watendlath is a hamlet and tarn (a small lake) in the Lake District in the English county of Cumbria, historically part of Cumberland, Watendlath is owned by the National Trust and sits high between the Borrowdale and Thirlmere valleys at above sea level. Watendlath Tarn Watendlath Tarn is fed by Bleatarn Gill from Blea Tarn, above, below Bell Crags. Water from Watendlath Tarn flows into the beck of the same name and eventually feeds Lodore Falls, and ends up in Derwent Water. The tarn is in size, with a maximum depth of . It was given to the National Trust by Queen Victoria's daughter, Princess Louise, in memory of her brother, King Edward VII. Watendlath Tarn is stocked with brown trout and rainbow trout and is a popular fly fishing water, with wading and boat fishing used. Governance Watendlath is within the Copeland UK Parliamentary constituency. Trudy Harrison is the Conservative Member of Parliament. Before Brexit for the European Parliament its residents voted ...

Blencathra
Blencathra, also known as Saddleback, is one of the most northerly hills in the English Lake District. It has six separate fell tops, of which the highest is the Hallsfell Top at 2,848 feet (868 metres). Name For many years, Ordnance Survey listed Blencathra under the alternative name of Saddleback, which was coined in reference to the shape of the mountain when seen from the east. The guidebook author Alfred Wainwright popularised the use of the older Cumbric name, which is now used almost exclusively. Ordnance Survey currently marks the summit as ‘Saddleback or Blencathra’. It is likely that the name Blencathra is derived from the Cumbric elements *''blain'' ‘top, summit’ and ''cadeir'' ‘seat, chair’, meaning ‘the summit of the seat-like mountain’. Andrew Breeze has proposed an alternative interpretation of the second element of the name, arguing that it represents a Cumbric cognate of Middle Welsh ''carthwr'' ‘working horse’. Richard Coates has sug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crinkle Crags
Crinkle Crags is a fell in the English Lake District in the county of Cumbria. It forms part of two major rings of mountains, surrounding the valleys of Great Langdale and Upper Eskdale. The name reflects the fell's physical appearance as its summit ridge is a series of five rises and depressions (crinkles) that are very distinctive from the valley floor. In Old English, ''cringol'' means twisted or wrinkled. Topography The nomenclature of the various tops is very confused. Traditional guidebooks tend to rely on what the eye sees and therefore focus attention upon the five ‘crinkles’ of the summit ridge. These are generally referred to as the first to fifth crinkles, but RichardsRichards, Mark: ''Mid-Western Fells'': Collins (2004): starts in the north, BirkettBirkett, Bill: ''Complete Lakeland Fells'': Collins Willow (1994): in the south and WainwrightAlfred Wainwright: ''A Pictorial Guide to the Lakeland Fells'', Book 4: employs both conventions, depending up ...

Helvellyn Range
The Helvellyn range is the name given to a part of the Eastern Fells in the English Lake District, "fell" being the local word for "hill". The name comes from Helvellyn, the highest summit of the group. The Helvellyn range forms a ridge extending for about 10 km, at no point dropping below 600 m. The ridge runs in a north–south direction, with Patterdale on the eastern side and the Thirlmere valley to the west. The village of Threlkeld lies directly to the north, below the northernmost point on the ridge, Clough Head. Generally, the slopes above Thirlmere are steep and grassy, whilst the Patterdale side exhibits rockier features, due to cirque glaciation on the north east side of the ridge. List of peaks The majority of the peaks in the range lie directly on the north–south axis, although there are some outliers on the eastern side of the ridge. *Clough Head (726 m) *Great Dodd (856 m) * Watson's Dodd (789 m) * Stybarrow Dodd (843 m) **Green ...

Porphyritic
Porphyritic is an adjective used in geology to describe igneous rocks with a distinct difference in the size of mineral crystals, with the larger crystals known as phenocrysts. Both extrusive and intrusive rocks can be porphyritic, meaning all types of igneous rocks can display some degree of porphyritic texture. Most Porphyritic rocks have bimodal size ranges, meaning the rock is composed of two distinct sizes of crystal. In extrusive rocks, the phenocrysts are surrounded by a fine-grained (aphanitic) matrix or groundmass of volcanic glass or non-visible crystals, commonly seen in porphyritic basalt. Porphyritic intrusive rocks have a matrix with individual crystals easily distinguished with the eye, but one group of crystals appearing clearly much bigger than the rest, as in a porphyritic granite. The term comes from the Ancient Greek (), meaning "purple". Purple was the color of royalty, and the "imperial porphyry" was a deep purple igneous rock with large crystals of pla ...

Garnet
Garnets () are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. The different species are pyrope, almandine, spessartine, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets make up two solid solution series: pyrope-almandine-spessartine (pyralspite), with the composition range ; and uvarovite-grossular-andradite (ugrandite), with the composition range . Etymology The word ''garnet'' comes from the 14th-century Middle English word ''gernet'', meaning 'dark red'. It is borrowed from Old French ''grenate'' from Latin ''granatus,'' from ''granum'' ('grain, seed'). This is possibly a reference to ''mela granatum'' or even ''pomum granatum'' ('pomegranate', ''Punica granatum''), a plant whose fruits contain abundant and vivid red seed covers ( arils), whic ...

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] |
