Armboth Fell
Armboth Fell is a fell in the English Lake District, regarded by Alfred Wainwright as the centre of Lakeland. It is named for the former settlement of Armboth. The fell is a domed plateau, three-quarters of a mile across, jutting out to the east of the Derwentwater-Thirlmere watershed, in the Borough of Allerdale. The fell is wet underfoot, with large areas clad in heather. The eastern slopes above Thirlmere have been planted with conifers. Topography Armboth Fell joins the main ridge via a shallow depression, a little to the south of High Tove, and due east of Middle Crag. This boggy low point is the source of both Fisher Gill and Launchy Gill, which form the fell's northern and southern boundaries respectively. Fisher Gill takes the shorter course, flowing straight for the shore of the reservoir through a break in the conifers below Cockrigg Crag. It enters the lake near the Armboth public car park. Launchy Gill flows across the plateau via Launchy Tarn. This is prominent on O ... [...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] |
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] |
Bowfell
Bowfell (named ''Bow Fell'' on Ordnance Survey maps) is a pyramid-shaped mountain lying at the heart of the English Lake District, in the Southern Fells area. It is the sixth-highest mountain in the Lake District and one of the most popular of the Lake District fells for walkers. It is listed in Alfred Wainwright's 'best half dozen' Lake District fells. Topography The Southern Fells include the highest ground in England, a horseshoe which begins with Scafell and Scafell Pike in the west and then curves around the north of Upper Eskdale to take in Great End, Esk Pike, Bowfell and Crinkle Crags. In addition to Eskdale, Bowfell has a footing in two other well known valleys. It stands at the head of Great Langdale — its east ridge dividing the two branches of Mickleden and Oxendale — while to the north is the Langstrath branch of Borrowdale. From all of these valleys Bowfell presents a striking profile with a conical top resting upon a wider summit plateau. To the north-w ...

Grisedale Pike
Grisedale Pike is a fell in the Lake District, Cumbria, England, situated west of the town of Keswick in the north-western sector of the national park. At a height of 791 m (2593 feet) it is the 40th-highest Wainwright in the Lake District; it also qualifies as a Hewitt, Marilyn and Nuttall. Grisedale Pike presents a striking appearance when viewed from the east, particularly from the vicinity of Keswick. It possesses two subsidiary summits: one unnamed (usually referred to as 'subsidiary summit', situated above Hobcarton Crag); the other Hobcarton End. Topography Grisedale Pike is a large fell throwing down three long ridges to the valley floors and two shorter ones that link to the adjoining fell of Hopegill Head and the strategically important Coledale Hause which links the fell to the rest of the Coledale Fells. It is bounded to the south by the 2½-mile (4-kilometre) valley of Coledale and to the north by the Whinlatter Pass which carries the B5292 ...

Helvellyn
Helvellyn (; possible meaning: ''pale yellow moorland'') is a mountain in the English Lake District, the highest point of the Helvellyn range, a north–south line of mountains to the north of Ambleside, between the lakes of Thirlmere and Ullswater. Helvellyn is the third-highest point both in England and in the Lake District, and access to Helvellyn is easier than to the two higher peaks of Scafell Pike and Scafell. The scenery includes three deep glacial coves and two sharp-topped ridges on the eastern side (Striding Edge and Swirral Edge). Helvellyn was one of the earliest fells to prove popular with walkers and explorers; beginning especially in the later 18th century. Among the early visitors to Helvellyn were the poets Samuel Taylor Coleridge and William Wordsworth, both of whom lived nearby at one period. Many routes up the mountain are possible so that it may be approached from all directions. However, traversing the mountain is not without dangers; over the last two h ...

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] |
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 ...

Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
