Bleaberry Fell
Bleaberry Fell is a fell in the Lake District in Cumbria, England, with a height of 590 metres (1,936 feet). It stands on the main watershed between Borrowdale and Thirlmere and can be climbed from either flank. Walla Crag is a subsidiary top of Bleaberry Fell. Topography Situated in the central area of the national park, four kilometres ( miles) south of Keswick, Bleaberry Fell is the northernmost top on the ridge that separates the valleys containing the lakes of Derwent Water (Borrowdale) and Thirlmere. This ridge, which also contains the fells of High Seat and High Tove, is notoriously boggy underfoot, but Bleaberry Fell is mostly dry and the heather-covered summit gives an excellent all-round vista. To the east the fell has the rock faces of Iron Crag and Goat Crags as it falls away towards the Thirlmere valley. Ascents The fell is usually climbed from the car park in Great Wood in Borrowdale, firstly ascending Walla Crag via Cat Gill and then continuing south-e ...

Hause Gate
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.

Keswick, Cumbria
Keswick ( ) is a market town and civil parishes in England, civil parish in the Allerdale Borough in Cumbria, England. Historic counties of England, Historically, until 1974, it was part of Cumberland. It lies within the Lake District National Park, Keswick is just north of Derwentwater and is from Bassenthwaite Lake. It had a population of 5,243 at the United Kingdom census, 2011, 2011 census. There is evidence of Prehistoric Cumbria, prehistoric occupation of the area, but the first recorded mention of the town dates from the 13th century, when Edward I of England granted a Royal charter, charter for Keswick's market, which has maintained a continuous 700-year existence. The town was an important Coal mining in the United Kingdom, mining area, and from the 18th century has been known as a holiday centre; tourism has been its principal industry for more than 150 years. Its features include the Moot Hall, Keswick, Moot Hall; a modern theatre, the Theatre by the Lake; one of Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porphyric
Porphyry ( ) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term ''porphyry'' refers to the purple-red form of this stone, valued for its appearance. The term ''porphyry'' is 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 plagioclase. Some authors claimed the rock was the hardest known in antiquity. Thus, "imperial"-grade porphyry was prized for monuments and building projects in Imperial Rome and thereafter. Subsequently, the name was given to any igneous rocks with large crystals. The adjective '' porphyritic'' now refers to a certain texture of igneous rock regardless of its chemical and mineralogical composition. Its chief character ...

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 ...

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] |
Phyric
300px, feldspathic phenocrysts. This granite, from the Switzerland">Swiss side of the Mont Blanc massif, has large white plagioclase phenocrysts, triclinic minerals that give trapezoid shapes when cut through). 1 euro coins, 1 euro coin (diameter 2.3 cm) for scale. A phenocryst is an early forming, relatively large and usually conspicuous crystal distinctly larger than the grains of the rock groundmass of an igneous rock. Such rocks that have a distinct difference in the size of the crystals are called porphyries, and the adjective porphyritic is used to describe them. Phenocrysts often have euhedral forms, either due to early growth within a magma, or by post-emplacement recrystallization. Normally the term ''phenocryst'' is not used unless the crystals are directly observable, which is sometimes stated as greater than .5 millimeter in diameter. Phenocrysts below this level, but still larger than the groundmass crystals, are termed ''microphenocrysts''. Very large phenocrysts ...

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] |
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 ...

High Tove
High Tove is a fell in the English Lake District, close to the geographical centre of the Cumbrian hills. It forms part of the watershed between the Derwentwater and Thirlmere catchments, a ridge running broadly north-south. Topography Sitting astride the spine of the Central Fells, High Tove is an outlier of High Seat. It is separated from its taller northern neighbour by the Pewits, an extremely boggy depression. The ridge moves on south across further upland marsh towards Ullscarf, passing over the three rocky (and dry) outcrops of Middle Crag, Shivery Knott and Watendlath Fell (summit unnamed on Ordnance Survey maps). Armboth Fell lies to the south east of High Tove, connected to the ridge by a broad heathery saddle. High Tove covers around one and a half miles of the north-south ridge, which is approximately a mile in width. It is bounded on the west by Watendlath Gill and its main feeder, Blea Tarn Gill. These flow to Watendlath Tarn, a popular beauty spot. The tarn is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derwent Water
Derwentwater, or Derwent Water, is one of the principal bodies of water in the Lake District National Park in north west England. It lies wholly within the Borough of Allerdale, in the county of Cumbria. The lake occupies part of Borrowdale and lies immediately south of the town of Keswick. It is both fed and drained by the River Derwent. It measures approximately long by wide and is some deep. There are several islands within the lake, one of which is inhabited. Derwentwater is a place of considerable scenic value. It is surrounded by hills (known locally as fells), and many of the slopes facing Derwentwater are extensively wooded. A regular passenger launch operates on the lake, taking passengers between various landing stages. There are seven lakeside marinas, the most popular stops being Keswick, Portinscale and the Lodore Falls, from which boats may be hired. Recreational walking is a major tourist activity in the area and there is an extensive network of foot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walla Crag
Walla Crag is a fell in the English Lake District, near Keswick. The fell is a short walk from Keswick and overlooks Derwentwater. Topography The crag is the terminal cliff on a short ridge running north west from Bleaberry Fell, dropping about 400 ft from the plateau above. Below this are further steep slopes before the gradient slackens on the shore of Derwentwater. The face is heavily wooded — mainly with conifers — almost to the top. The trees continue down through Great Wood to the lake. Walla Crag has one major breach, Lady's Rake. The summit lies a little way back from the brink, the smooth heather-clad hinterland then dropping to the broad depression of Low Moss. Beyond here the ground rises again to Bleaberry Fell. The southern boundary of the fell is formed by Cat Gill, which flows west from Loss Moss to the lake. The gill separates Walla Crag from the neighbouring Falcon Crag, popular with rock climbers. Brockle Beck flows north from Low Moss, before turnin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
