Ladder Hills
The Ladder Hills ( gd, Monadh an Fhàraidh) are a range of hills in northeast Scotland which straddle the border between Aberdeenshire and Moray and form a part of the Grampian Mountains. The highest point of the range is Càrn Mòr at , which is classed as a Corbett; other named tops include Monadh an t-Sluich Leith (800m), Carn Liath (792m), Dun Muir (754m) and Little Geal Charn (742m). The hills are formed for the most part from late Precambrian age metamorphosed sandstones and mudstones; quartzites, psammites, pelites and semipelites which together form the Ladder Hills and Kymah Quartzite formations. These are placed within the Islay Subgroup of the Argyll Group, itself a division of the late Dalradian Supergroup. Parts of the range are formed from carbonate rich rocks. Metadolerite dykes intrude this sequence in places. The rock strata are intensely folded and typically dip steeply to the southeast or northwest. The range takes its name from the Ladder Road, a high pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...

Mountains And Hills Of Aberdeenshire
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Raven
A raven is any of several larger-bodied bird species of the genus ''Corvus''. These species do not form a single taxonomic group within the genus. There is no consistent distinction between "crows" and "ravens", common names which are assigned to different species chiefly on the basis of their size. The largest raven species are the common raven and the thick-billed raven. Etymology The term "raven" originally referred to the common raven (''Corvus corax''), the type species of the genus ''Corvus'', which has a larger distribution than any other species of ''Corvus'', ranging over much of the Northern Hemisphere. The modern English word ''raven'' has cognates in all other Germanic languages, including Old Norse (and subsequently modern Icelandic) and Old High German , all of which descend from Proto-Germanic . Collective nouns for a group of ravens (or at least the common raven) include "rave", "treachery", "unkindness" and "conspiracy". In practice, most people use the more ...

Dotterel
The Eurasian dotterel (''Charadrius morinellus''), also known in Europe as just dotterel, is a small wader in the plover family of birds. The dotterel is a brown and black streaked bird with a broad white eye-stripe and an orange-red chest band when in breeding plumage. The female is more colourful than the male. The bird is tame and unsuspecting and the term "dotterel" has been applied contemptuously to mean an old fool. The Eurasian dotterel is a migratory species, breeding in northern Europe and Eurosiberia and migrating south to north Africa and the Middle East in the winter. It nests in a bare scrape on the ground and lays two to four eggs. The male does the incubation and rears the chicks, the female having gone off to find another male and lay another clutch of eggs. It is a common bird with a wide range and the International Union for Conservation of Nature has rated it as being of "least concern". Etymology The English name dates from 1440 when it was used to refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunlin
The dunlin (''Calidris alpina'') is a small wader, formerly sometimes separated with the other "stints" in the genus ''Erolia''. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from ''dun'', "dull brown", with the suffix ''-ling'', meaning a person or thing with the given quality. It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in northern Europe and Asia are long-distance migrants, wintering south to Africa, southeast Asia and the Middle East. Birds that breed in Alaska and the Canadian Arctic migrate short distances to the Pacific and Atlantic coasts of North America, although those nesting in northern Alaska overwinter in Asia. Many dunlins winter along the Iberian south coast. Taxonomy The dunlin was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa alpina''. Linnaeus specified the location as Lapland. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Plover
'' Pluvialis '' is a genus of plovers, a group of wading birds comprising four species that breed in the temperate or Arctic Northern Hemisphere. In breeding plumage, they all have largely black underparts, and golden or silvery upperparts. They have relatively short bills and feed mainly on insects, worms or other invertebrates, depending on habitat, which are obtained by a run-and-pause technique, rather than the steady probing of some other wader groups. They hunt by sight, rather than by feel as do longer-billed waders. Taxonomy The genus ''Pluvialis'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the European golden plover (''Pluvialis apricaria'') as the type species. The genus name is Latin and means relating to rain, from ''pluvia'', "rain". It was believed that they flocked when rain was imminent. The genus contains four species: The American and Pacific golden plovers were formerly considered conspecific Biological specificity is th ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Blanket Bog
Blanket bog or blanket mire, also known as featherbed bog, is an area of peatland, forming where there is a climate of high rainfall and a low level of evapotranspiration, allowing peat to develop not only in wet hollows but over large expanses of undulating ground. The blanketing of the ground with a variable depth of peat gives the habitat type its name. Blanket bogs are found extensively throughout the northern hemisphere - well-studied examples are found in Ireland and Scotland, but vast areas of North American tundra also qualify as blanket bogs. In Europe, the southernmost edge of range of this habitat has been recently mapped in the Cantabrian Mountains, northern Spain, but the current distribution of blanket bogs globally remains unknown. In the southern hemisphere they are less well-developed due to the relatively low latitudes of the main land areas, though similar environments are reported in Patagonia, the Falkland Islands and New Zealand. The blanket bogs known as 'f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Area Of Conservation
A Special Area of Conservation (SAC) is defined in the European Union's Habitats Directive (92/43/EEC), also known as the ''Directive on the Conservation of Natural Habitats and of Wild Fauna and Flora''. They are to protect the 220 habitats and approximately 1,000 species listed in annex I and II of the directive which are considered to be of European interest following criteria given in the directive. They must be chosen from the Sites of Community Importance by the member states and designated SAC by an act assuring the conservation measures of the natural habitat. SACs complement Special Protection Areas and together form a network of protected sites across the European Union called Natura 2000. This, in turn, is part of the Emerald network of Areas of Special Conservation Interest (ASCIs) under the Berne Convention. Assessment methodology in the United Kingdom Prior to being designated as a Special Area of Conservation (SAC), sites have been assessed under a two-stage process ...

Cairngorms National Park
Cairngorms National Park ( gd, Pàirc Nàiseanta a' Mhonaidh Ruaidh) is a national park in northeast Scotland, established in 2003. It was the second of two national parks established by the Scottish Parliament, after Loch Lomond and The Trossachs National Park, which was set up in 2002. The park covers the Cairngorms range of mountains, and surrounding hills. Already the largest national park in the United Kingdom, in 2010 it was expanded into Perth and Kinross. Roughly 18,000 people reside within the 4,528 square kilometre national park. The largest communities are Aviemore, Ballater, Braemar, Grantown-on-Spey, Kingussie, Newtonmore, and Tomintoul. Tourism makes up about 80% of the economy. In 2018, 1.9 million tourism visits were recorded. The majority of visitors are domestic, with 25 per cent coming from elsewhere in the UK, and 21 per cent being from other countries. Geography The Cairngorms National Park covers an area of in the council areas of Aberdeenshire, Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A939 Road
The A939 'Lecht Road' connects the A96 at Nairn on the Moray Coast with the A95 Grantown on Spey, then it continues to the A93 at Ballater by way of the Grampian Mountains, passing Tomintoul and the Lecht Ski Centre. This road passes over four summits: #at Dava Moor 1053 ft (321m), #west of Bridge of Brown 1436 ft (438m), #at the Lecht Ski Centre 2090 ft (637m), #at the Gairnshiel Summit 1836 ft (550m). On the old A939, now redesignated the B976 between Gairnshiel Bridge and Crathie, the road reaches 1568 ft (478m). The A939 is regularly the first road in Great Britain closed due to snowfall between Cock Bridge and Tomintoul.
