Knott Rigg
Knott Rigg is a fell at the head of the Newlands Valley in the English Lake District. It is situated some 8.5 kilometres south west of Keswick and has a modest height of 556 metres (1825 feet). Its name is derived from the Old English language and means ''“hill on a knobbly ridge”''. Because of its moderate height, the fell fails to be listed on any significant hill lists but it does merit a separate chapter in Alfred Wainwright’s Pictorial Guide to the Lakeland Fells. Topography Knott Rigg is located on a four kilometre long ridge, which springs from Rigg Beck in the Newlands valley midway along its length and runs south westerly to conclude at Newlands Hause. The ridge also contains the adjoining fell of Ard Crags which stands 1.5 kilometres north east of Knott Rigg; both fells are usually climbed in combination with each other. Knott Rigg is steep sided, with the western flank falling away to the valley of Sail Beck, while the eastern side descends to the min ...

Ard Crags
Ard Crags is a fell in the Lake District in Cumbria, England, it is situated in the Newlands Valley just off the minor road between Keswick and Buttermere. The Ordnance Survey officially records the fell's altitude at , considerably more than the approximate that Alfred Wainwright attributed to it in his ''Pictorial Guide to the North Western Fells'', published in 1964 well before the advent of satellite mapping. Ard Crags is situated close to other higher fells such as Causey Pike and Eel Crag and can be easily overlooked. However, viewed from certain points in the Rigg Beck or Newlands valley area it presents a clearly defined and pyramidal shape which catches the eye. Topography A long high ridge sweeps east from Whiteless Pike, via Wandope, Crag Hill, Sail (Lake District) and Causey Pike, crossing from Buttermere to Stair. Running parallel to the south is a lower ridge, a tenuous connection made centrally at Sail. This lower ridge consists of Knott Rigg and Ard Crags, and h ...

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 ...

Skiddaw
Skiddaw is a mountain in the Lake District National Park in England. Its summit is the sixth-highest in England. It lies just north of the town of Keswick, Cumbria, and dominates the skyline in this part of the northern lakes. It is the simplest of the Lake District mountains of this height to ascend (as there is a well-trodden tourist track from a car park to the north-east of Keswick, near the summit of Latrigg) and, as such, many walking guides recommend it to the occasional walker wishing to climb a mountain. This is the first summit of the fell running challenge known as the Bob Graham Round when undertaken in a clockwise direction. The mountain lends its name to the surrounding areas of Skiddaw Forest and Back o' Skidda, and to the isolated Skiddaw House, situated to the east, formerly a shooting lodge and subsequently a youth hostel. It also provides the name for the slate derived from that region: Skiddaw slate. Skiddaw slate has been used to make tuned percussi ...

High Spy
High Spy is a fell in the English Lake District it is situated on the ridge that separates the Newlands Valley from Borrowdale, eight kilometres (five miles) south of Keswick. Topography The fell reaches a height of 653 metres (2142 feet) and is defended by crags to the east and west as it falls away steeply to the valleys. It is a distinctive fell that has 148 metres (486 feet) of topographic prominence from the higher adjoining fell of Dale Head and so misses being a Marilyn by only two metres. Geologically the fell is made up of Borrowdale Volcanics. The meaning of the fell's name is obscure but may mean a “lookout post”, referring to some lost fort in the area. In the past it has been known as Scawdel Fell and Lobstone Band and these names are still used on maps to label other parts of the fell.ukonline.co.uk. deta ...

Causey Pike
Causey Pike is a fell in the English Lake District. It is situated in the Newlands Valley, 5 km south-west of the town of Keswick. Even though it has a modest height of 637 metres (2,090 ft) it is one of the most distinctive fells when viewed from the Derwent Water and Keswick area due to its distinguishing summit "knobble" which catches the eye. The fell is one of 214 fells described by Alfred Wainwright in his series of ''Pictorial Guides to the Lakeland Fells'': Causey Pike features in Book Six, ''The North Western Fells''. 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 Causey Pike. The highest ground in the North Western Fells is an east–west ridge in this central sector, begi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

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] |
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] |
Olistostrome
An olistostrome is a sedimentary deposit composed of a chaotic mass of heterogeneous material, such as blocks and mud, known as olistoliths, that accumulates as a semifluid body by submarine gravity sliding or slumping of the unconsolidated sediments. It is a mappable stratigraphic unit which lacks true bedding, but is intercalated amongst normal bedding sequences, as in the Cenozoic basin of central Sicily. The term olistostrome is derived from the Greek ''olistomai'' (to slide) and ''stroma'' (accumulation).Ernesto Abbate, et al., "Olistostromes and olistoliths", ''Sedimentary Geology'', 4 (1970), 521-557. See also *Submarine landslide Submarine landslides are marine landslides that transport sediment across the continental shelf and into the deep ocean. A submarine landslide is initiated when the downwards driving stress (gravity and other factors) exceeds the resisting str ... References Sedimentary rocks {{Geology-stub ...

Buttermere
Buttermere is a lake in the Lake District in North West England. The adjacent village of Buttermere takes its name from the lake. Historically in Cumberland, the lake is now within the county of Cumbria. Owned by the National Trust, it forms part of its Buttermere and Ennerdale property. Geography The lake is long by wide, and is deep. It has an elevation above sea level of . It is situated towards the head of the valley of the River Cocker and is surrounded by fells, notably the High Stile range to the south west, Robinson to the north-east, Fleetwith Pike and Haystacks to the south-east and Grasmoor to the north-west. The village of Buttermere stands at the north-western end of the lake, and beyond this is Crummock Water. There is a path around the lake which is about long, and at one point runs through a rock tunnel beneath the locality of Hassness. Access is by road, from Cockermouth in the north-west; from Borrowdale via the Honister Pass; or from Braithwaite and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newlands Hause
The Newlands Pass, also known as Newlands Hause, is a mountain pass in the English Lake District. It is located on an unclassified road linking the Newlands Valley, to the west of Keswick and Derwent Water, with the village of Buttermere. The highest point on the pass is at an altitude of , and it has gradients of 1 in 4 on both sides. The Newlands Pass is one of three passes that link the tourist area around Keswick, including Derwent Water and Borrowdale, with the valley of the River Cocker, including the lakes of Buttermere, Crummock Water and Loweswater. From north to south these passes are the Whinlatter Pass, the Newlands Pass, and the Honister Pass Honister Pass is a mountain pass in the English Lake District. It is located on the B5289 road, linking Seatoller, in the valley of Borrowdale, to Gatesgarth at the southern end of Buttermere. The pass reaches an altitude of , making it ....
