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] |

Scar Crags
Scar Crags is a fell in the north western part of the English Lake District in the county of Cumbria. It is one of the Coledale group of fells situated seven kilometres south west of Keswick and reaches a height of 672 metres (2205 feet). Topography The fell is part of the long ridge that radiates easterly from Eel Crag and includes the adjoining fells of Sail and Causey Pike before dropping to the Newlands Valley. Scar Crags is characterised by steep craggy flanks on its southern side which fall away steeply to Rigg Beck, while the northern slopes are less steep and grassy as they drop to Stoneycroft Gill. Geology The ridgeline is composed of the laminated mudstone and siltstone of the Kirkstile Formation.British Geological Survey: 1:50,000 series maps, ''England & Wales Sheet 29'': BGS (1999) Ascents Scar Crags is very rarely climbed directly. The only feasible direct ascent follows an old mine road that starts from Stair and goes up Stoneycroft Gill to finish at Sail Pa ...

Newlands Pass
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 ....

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 ...

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] |
Skiddaw Group
''For the Skiddaw group of hills, see Skiddaw Group'' The Skiddaw Group is a group of sedimentary rock formations named after the mountain Skiddaw in the English Lake District. The rocks are almost wholly Ordovician in age ( Tremadoc through Arenig to Llanvirn epochs) though the lowermost beds are possibly of Cambrian age. This rock sequence has previously been known as the Skiddaw Slates, the Skiddaw Slates Group and the Skiddavian Series. Its base is not exposed but in its main outcrop area, it is considered to be in excess of thick though less elsewhere. It consists largely of mudstones and siltstones with subordinate wacke-type sandstones. Their main occurrence is within the northern and central fells of the Lake District, either side of the major ENE-WSW aligned Causey Pike Fault, but inliers are found at Black Combe in the south of the Lake District and at Cross Fell in the North Pennines.

Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Union of Geological Sciences, Intern ...

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 ...

Outerside
Outerside is a fell in the Lake District in Cumbria, England. It is located 6 kilometres west of Keswick in the north western part of the national park and is a smaller member of the Coledale group of fells with a height of 568 metres (1863 feet). The fell is part of a ridge on the southern side of Coledale which descends from the higher fell of Scar Crags and continues over the neighbouring smaller fell of Barrow before reaching the valley at the village of Braithwaite. 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 Outerside. The highest ground in the North Western Fells is an east–west ridge in this central sector, beginning with Grasmoor above Crummock Water and then gradually des ...

Barrow (Lake District)
Barrow is small fell in the English Lake District in the county of Cumbria which reaches a height of 455 metres (1,494 feet). It is in the Newlands Valley 2.5 miles (4 km) south-west of Keswick. Although comparatively small in height, Barrow commands an all-round view, with the vales of Keswick and Newlands being visible. The name of the fell originates from the Anglo Saxon language meaning a hill or long ridge. Topography Barrow is a slender ridge climbing south-west from Braithwaite. At the summit it turns due west across the depression of Barrow Door, diverted by the valley of Stonycroft Gill. Beyond the col are Stile End and Outerside. The valley of Coledale lies to the north-west and Newlands Beck forms the eastern boundary. Ascents Ascents of the fell are usually started from either the Newlands Valley or Braithwaite, both providing a short ramble which can be combined with the adjoining higher fell of Outerside. The climb from Newlands starts at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sail (Lake District)
Sail is a hill in the English Lake District, lying between Derwentwater and Crummock Water. 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 Sail. The highest ground in the North Western Fells is an east-west ridge in this central sector, beginning with Grasmoor above Crummock Water and then gradually descending eastwards over Crag Hill, Sail, Scar Crags and Causey Pike. Sail is in every sense a satellite of Crag Fell, although having sufficient prominence to be listed as a Hewitt. From the summit of Crag Hill the eastward ridge narrows between opposing walls of crag. This rocky crest is The Scar, the depression being at around 2,425 ft.
