Arkle (Sutherland)
Arkle () is a mountain in Sutherland, in the far north-west corner of the Scottish Highlands. Like its sister Foinaven, the mountain is made up of glistening white Cambrian quartzite, laid down around 530 million years ago on an uneven basement of much older Lewisian gneiss. The quartzite, and the Torridonian sandstone which makes up many of the other mountains in the area, have been dissected by rivers and glaciers, leaving a series of isolated peaks, such as Suilven, Quinag and Stac Pollaidh, standing above the "knock and lochan" landscape of small hills and lakes that is typical of the Lewisian gneiss. 'Ben Arkle' was the subject of a painting by Charles, Prince of Wales. This painting was reproduced by the British Post Office as one of a set of five stamps (SG 1810–1814, issued 1 March 1994) showing paintings by Prince Charles and also, as a commemorative label, in a stamp book (SG HB16) issued 14 November 1994 to celebrate the Prince's 50th birthday.

The first list was compiled in the 1920s by John Rooke Corbett, a Bristol-based climber and Scottish Mountaineering Club ("SMC") member, and was published posthumously, after his sister passed it to the SMC, in the 1953 edition of ''Munro's Tables''. Corbetts are the next category down from the Munros and Munro Tops in terms of height (e.g. below the threshold), but their explicit prominence threshold of , ensure they are material peaks. By definition, all Corbetts, given their prominence, are Marilyns. The SMC keeps a list of Corbetts. , there were 222 Corbetts in Scotland. 21 of these 222 Corbetts have a prominence that exceeds the P600 threshold of , which would class them as "Majors".

Cambrian
The Cambrian Period ( ; sometimes symbolized C with bar, êž’) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 million years ago (mya) to the beginning of the Ordovician Period mya. Its subdivisions, and its base, are somewhat in flux. The period was established as "Cambrian series" by Adam Sedgwick, who named it after Cambria, the Latin name for 'Cymru' (Wales), where Britain's Cambrian rocks are best exposed. Sedgwick identified the layer as part of his task, along with Roderick Murchison, to subdivide the large "Transition Series", although the two geologists disagreed for a while on the appropriate categorization. The Cambrian is unique in its unusually high proportion of sedimentary deposits, sites of exceptional preservation where "soft" parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marilyns Of Scotland
This is a list of Marilyn hills and mountains in the United Kingdom, Isle of Man and Ireland by height. Marilyns are defined as peaks with a prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,011 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophonous with (Marilyn) '' Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Marilyn was the first of several subsequent British Isles classifications that rely solely on prominence, including the P600s, the HuMPs, and the TuMPs. Topographic prominence is a more difficult to estimate than t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoroughbred
The Thoroughbred is a horse breed best known for its use in horse racing. Although the word ''thoroughbred'' is sometimes used to refer to any breed of purebred horse, it technically refers only to the Thoroughbred breed. Thoroughbreds are considered " hot-blooded" horses that are known for their agility, speed, and spirit. The Thoroughbred, as it is known today, was developed in 17th- and 18th-century England, when native mares were crossbred with imported Oriental stallions of Arabian, Barb, and Turkoman breeding. All modern Thoroughbreds can trace their pedigrees to three stallions originally imported into England in the 17th and 18th centuries, and to a larger number of foundation mares of mostly English breeding. During the 18th and 19th centuries, the Thoroughbred breed spread throughout the world; they were imported into North America starting in 1730 and into Australia, Europe, Japan and South America during the 19th century. Millions of Thoroughbreds exist today, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arkle
Arkle (19 April 1957 – 31 May 1970) was an Irish Thoroughbred racehorse. A bay gelding by ''Archive'' out of ''Bright Cherry'', he was the grandson of the unbeaten (in 14 races) flat racehorse and prepotent sire Nearco. Arkle was bred by Mary Baker of Malahow House, near Naul, County Dublin, and was born at Ballymacoll Stud, County Meath. He was owned by Anne Grosvenor, Duchess of Westminster, who named him after the mountain Arkle in Sutherland, Scotland, that bordered her Sutherland estate. Trained by Tom Dreaper at Greenogue, Kilsallaghan in County Meath, Ireland, he was ridden during his steeplechasing career by Pat Taaffe. Arkle won three Cheltenham Gold Cups and a number of other top races before his career was cut short by injury. At 212, his Timeform rating is the highest ever awarded to a steeplechaser. Early life Arkle, a bay colt with no white markings, was bred by Mary Baker, who kept a few mares on the family farm at Malahow, near Naul in County Dublin. His d ...

Stac Pollaidh
Stac Pollaidh (IPA: ˆs̪t̪ʰaÊ°kˈpʰɔɫ̪ais a mountain in the Northwest Highlands of Scotland. The peak displays a rocky crest of Torridonian sandstone, with many pinnacles and steep gullies. The ridge was exposed to weathering as a nunatak above the ice sheet during the last Ice Age, while the ice flow carved and scoured the smooth sides of the mountain. The modern Gaelic name is a recent invention. The peak is named on the first edition Ordnance Survey maps simply as "An Stac" (the pinnacle) and on later maps as "Stac Polly". The "Polly" element is of Norse origin, derived from "PollÃ¥" meaning "pool river". Due to its relatively low height of just over 2000 feet, fine views and ease of access from a road it has become a very popular peak to climb. It also provides some fine scrambling in the traverse of the summit ridge, including one ''bad step'' near the final summit. Consequentially it has suffered from a great deal of erosion, leading to Scottish Natural Heritage co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torridonian Sandstone
In geology, the term Torridonian is the informal name for the Torridonian Group, a series of Mesoproterozoic to Neoproterozoic arenaceous and argillaceous sedimentary rocks, which occur extensively in the Northwest Highlands of Scotland. The strata of the Torridonian Group are particularly well exposed in the district of upper Loch Torridon, a circumstance which suggested the name Torridon Sandstone, first applied to these rocks by James Nicol. Stratigraphically, they lie unconformably on gneisses of the Lewisian complex and their outcrop extent is restricted to the Hebridean Terrane. Rock type The rocks are mainly red and brown sandstones, arkoses and shales with coarse conglomerates locally at the base. Some of the materials of these rocks were derived from the underlying Lewisian gneiss, upon the uneven surface of which they rest, but the bulk of the material was obtained from rocks that are nowhere now exposed. Upon this ancient denuded land surface the Torridonian strat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewisian Complex
The Lewisian complex or Lewisian gneiss is a suite of Precambrian metamorphic rocks that outcrop in the northwestern part of Scotland, forming part of the Hebridean Terrane and the North Atlantic Craton. These rocks are of Archaean and Paleoproterozoic age, ranging from 3.0–1.7 billion years ( Ga). They form the basement on which the Torridonian and Moine Supergroup sediments were deposited. The Lewisian consists mainly of granitic gneisses with a minor amount of supracrustal rocks. Rocks of the Lewisian complex were caught up in the Caledonian orogeny, appearing in the hanging walls of many of the thrust faults formed during the late stages of this tectonic event. Distribution The main outcrops of the Lewisian complex are on the islands of the Outer Hebrides, including Lewis, from which the complex takes its name. It is also exposed on several islands of the Inner Hebrides, small islands north of the Scottish mainland and forms a coastal strip on the mainland from near L ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Loch Stack
Loch Stack is a large, irregularly shaped freshwater loch in the Northwest of Scotland. It lies approximately southeast of Laxford Bridge and is surrounded by mountains. Ben Stack rises steeply from the loch's southwestern shore and Arkle (Sutherland), Arkle lies directly to the north. Survey The loch was surveyed between 6 and 8 September 1902 by T.N. Johnston and James Murray and later charted as part of the John Murray (oceanographer), Sir John Murray's ''Bathymetrical Survey of Fresh-Water Lochs of Scotland 1897-1909''.
