Pike Of Stickle
Pike of Stickle, also known as Pike o’ Stickle, is a fell in the English Lake District. It reaches a height of 709 metres (2,326 feet) and is situated in the central part of the national park in the valley of Great Langdale. The fell is one of three fells which make up the picturesque Langdale Pikes (the others being Harrison Stickle and Loft Crag), one of the best-known areas in Lakeland. A "stickle" is a hill with a steep prominent rocky top, while a "pike" is a hill with a peaked summit, the name being therefore partly tautological. Topography The Langdale Pikes form a raised rocky parapet around the southern and eastern edges of a high tableland centred upon Thunacar Knott. Pike of Stickle stands at the western end of this system and its crags fall south from the summit, presenting an arresting view from the valley floor 2,000 ft below, or from further afield. Loft Crag stands next along the rampart, with Thorn Crag and Harrison Stickle further to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loft Crag
Loft Crag is a fell in the English Lake District, situated west of Ambleside in the valley of Great Langdale. Along with the neighbouring fells of Harrison Stickle and Pike of Stickle it forms the picturesque Langdale Pikes, which when viewed from the area around Elterwater village gives one of the best-known views in the National Park. Topography The Langdale Pikes form a parapet to the lower hinterland to their north. From 'behind' they are unimpressive, but their southern faces fall full length over crags to the floor of Langdale, nearly below. Loft Crag has a peaked summit which apes in lesser proportion the fine knoll of Pike of Stickle. To the east, between Loft Crag and Harrison Stickle is the subsidiary top of Thorn Crag. This is sometimes counted as a Langdale Pike in its own right, but only Birkett amongst the major guidebooks takes this view.Bill Birkett: Complete Lakeland Fells: Collins Willow (1994): Ascents Loft Crag has a summit elevation of .

Tarn (lake)
A tarn (or corrie loch) is a proglacial mountain lake, pond or pool, formed in a cirque excavated by a glacier. A moraine may form a natural dam below a tarn. Etymology The word is derived from the Old Norse word ''tjörn'' ("a small mountain lake without tributaries") meaning pond. In parts of Northern England - predominantly Cumbria but also areas of North Lancashire and North Yorkshire - 'tarn' is widely used as the name for small lakes or ponds, regardless of their location and origin (e.g. Talkin Tarn, Urswick Tarn, Malham Tarn). Similarly, in Scandinavian languages, a ''tjern'' or ''tjørn'' (both Norwegian) or ''tjärn'' or ''tärn'' (both Swedish) is a small natural lake, often in a forest or with vegetation closely surrounding it or growing into the tarn. The specific technical use for a body of water in a glacial corrie comes from high number of tarns found in corries in the Lake District, an upland area in Cumbria. Nonetheless, there are many more bodies of wat ... [...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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyolitic
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lapilli
Lapilli is a size classification of tephra, which is material that falls out of the air during a volcanic eruption or during some meteorite impacts. ''Lapilli'' (singular: ''lapillus'') is Latin for "little stones". By definition lapilli range from in diameter. A pyroclastic particle greater than 64 mm in diameter is known as a volcanic bomb when molten, or a volcanic block when solid. Pyroclastic material with particles less than 2 mm in diameter is referred to as volcanic ash. Formation Lapilli are spheroid-, teardrop-, dumbbell- or button-shaped droplets of molten or semi-molten lava ejected from a volcanic eruption that fall to earth while still at least partially molten. These granules are not accretionary, but instead the direct result of liquid rock cooling as it travels through the air. Lapilli tuffs are a very common form of volcanic rock typical of rhyolite, andesite and dacite pyroclastic eruptions, where thick layers of lapilli can be deposited durin ...

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a vol ...

Breccia
Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its source area, since other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
