Beinn Eighe

Located between Loch Maree and Glen Torridon on the west coast of Scotland, Beinn Eighe is a complex mountain. The main ridge runs on a line extending from close to the village of Kinlochewe in the north-east to the narrow glen of the Coire Dubh Mòr, which separates it from the neighbouring mountain of Liathach to the south-west. The slopes into Glen Torridon on the south side are steep with few features and are covered in white quartzite screes. On the north side are four large corries between which are spurs extending out from the main ridge. The southern and eastern sides of the mountain are flanked by the A896 and A832 roads, however the area to the northwest is largely unpopulated, comprising the mountainous landscape of the Torridon Hills and the Flowerdale Forest. Two of Beinn Eighe's summits are classified as Munros. The highest point Beinn Eighe, Ruadh-stac Mòr ('Big Red Stack' in Scottish Gaelic), lies on one of the spurs off the main ridge and stands at a height of . Spidean Coire nan Clach ('Peak of the Corrie of Stones' in Scottish Gaelic), which was added to the list of Munros in 1997 to become the second Munro on Beinn Eighe, is the highest point on the main ridge itself. It stands at a height of and commands an extensive view over both Glen Torridon and the rest of the Beinn Eighe massif. Ruadh-stac Beag (), which lies on a spur from the main ridge east of Ruadh-stac Mòr, has sufficient relative height to be classified as a Corbett. One of the most famous features of Beinn Eighe is the corrie of Coire Mhic Fhearchair, often simply known as the "Triple Buttress Corrie" after the three large rock features which dominate the view from the north. There are many rock climbs on the buttresses and hillwalkers can access the tops of the buttresses from the head of the corrie. ==Geology==

In common with much of the Northwest Highlands, the underlying rocks of the area are composed of Lewisian gneiss, a very ancient rock type. The younger Precambrian Torridonian Sandstone, which sits on top of the gneiss, forms the bulk of all of the Torridon Hills, including Beinn Eighe, and was formed around 800 million years ago from the sediment of rivers that flowed across the landscape of the gneiss. Beinn Eighe is however unusual amongst the Torridon Hills in that the summit ridge is composed of white-coloured Cambrian basal quartzite. This is a very hard but brittle rock, that was laid down around 540 million years ago as pure white sands during a period when the area was flooded by warm tropical seas. The quartzite gives Beinn Eighe its familiar light coloured summits, which form a notable contrast to the other peaks in the area, and can appear similar to a covering of snow on the mountain. Within the Cambrian rocks a distinct rock layer, known as the Fucoid Beds, has been identified. The fossils found in the Fucoid Beds are very different to those from rocks of a similar age found in England, a fact that was crucial in establishing that during the Cambrian period the two land masses were separated by ocean. These fossils, which include trilobites, and worm burrows, are some of the oldest fossils to be found in Scotland. The fossil of one creature identified in the rocks of Beinn Eighe, Olenellus armatus, has not been found at any other location. The area was heavily sculpted by glaciers during successive ice ages. ==Flora and fauna==

Many rare plants, including two variants of dwarf shrub heath and a western variant of moss heath, are to be found at Beinn Eighe. In total 680 different species of plants have been identified, including the greatest variety of oceanic mosses and liverworts of any single site in Britain. The summit plateau is the only location in Britain at which the liverwort Herbertus borealis (northern prongwort) has been found; whilst Beinn Eighe is also the most northerly known global location at which the moss species Daltonia splachnoides has been identified. The Scots pine in this area show genetic differences to those in eastern parts of Scotland, and are more similar to those growing in southern Europe. It is thought that this results from the fact that western Scotland became ice-free first at the end of the last ice-age, allowing pine to move north along the western fringe of Europe. Pines reached Eastern Scotland from more northerly areas during a later period, as the ice sheets retreated further. Bird species observed at Beinn Eighe include golden eagles, Scottish crossbills, bramblings, ring ouzels, golden plovers, skylarks, redwings and divers. The reserve is home to mammal species including red deer, mountain hare and pine martens, although the Scottish wildcat has not been observed for many years. Otters breed along the shores of Loch Maree, and have been sighted on burns and lochans up to 400 m above sea level. == Ascents ==

Beinn Eighe's complex topography offers both hillwalkers and climbers a wide variety of routes, climbs and traverses. For the hillwalker a popular route is the western traverse which includes both of the Munro summits and Coire Mhic Fhearchair. A full traverse of Beinn Eighe includes navigating a series of pinnacles known as the Black Carls, which provide good scrambling and are located at the eastern end of the main ridge. Approached from the east the Black Carls are a popular climb in their own right. The cartographer Timothy Pont visited the Loch Maree area when producing his series of maps of Scotland in the late sixteenth century, including a sketch of Coire Mhic Fhearchair on his maps, however there is little evidence of any recorded visits to the summits of Beinn Eighe prior to the nineteenth century. The earliest recorded ascent appears to have been during surveying of the boundary between the Gairloch and Torridon Estates, which surveyor George Campbell Smith was required to determine and delineate in 1851. ==Air crash==

The Triple Buttress Corrie was the scene of an aviation tragedy on the night of 13–14 March 1951. An Avro Lancaster crashed about 5 m below the crest of the summit ridge in a gully now known as Fuselage Gulley (or Far West Gulley) above Loch Coire Mhic Fhearchair. The aircraft, which was part of 120 Squadron, had taken off from RAF Kinloss around 6 pm for a maritime reconnaissance mission in the vicinity of Rockall and the Faroe Isles, and was due back at around 2:30 am. During the return journey the weather conditions were poor, with freezing temperatures and a strong north-easterly wind. • Fl/Lt Harry Smith Reid DFC (29), Pilot, RAF. • Sgt Ralph Clucas (23), Co-Pilot, RAF. • Flt Lt Robert Strong (27), Navigator, RAF. • Fl/Lt Peter Tennison (26), Air Signals, RAF. • Sgt James Naismith (28), Air Signals, RAF. • Sgt Wilfred D Beck (19), Air Signals, RAF. • Sgt James W Bell (25), Air Signals, RAF. • Sgt George Farquhar (29), Flight Engineer, RAF. == Beinn Eighe National Nature Reserve ==

The Beinn Eighe National Nature Reserve covers 4758 hectares, including open moorland, woodland and bogs. It was established in 1951 by Dr John Berry in his role as Director of Nature Conservancy in Scotland, and was the first such area in Great Britain. In 2014 the Beinn Eighe NNR was merged with the neighbouring Loch Maree Islands NNR, which covers over 60 islands in Loch Maree to be managed as a single Beinn Eighe and Loch Maree Islands NNR, although the two reserves are still formally designated separately. Most of the Beinn Eighe reserve is owned by NatureScot, although an area of 577 ha on the western side belongs to the National Trust for Scotland. NatureScot provides a visitor centre at Aultroy, just over a kilometre northwest of Kinlochewe. From the visitor centre there are several marked trails through woodland on the lower slopes of Beinn Eighe, as well as picnic areas and viewpoints. Further to west, NatureScot have constructed two further routes: the 1.5 km-long Woodland Trail passes through the pinewood of the Coille na Glas Leitir, whilst the 6.5 km-long Mountain Trail climbs to the "Conservation Cairn" at c. which offers extensive views of the surrounding landscape including Loch Maree and the nearby mountain Slioch. NatureScot also provides a field station with full laboratory facilities for up to fourteen people which is used by scientists and researchers to co-ordinate field data recording and as a base for undergraduate fieldwork. A tree nursery lies alongside the field station; trees are raised from local stock for planting on the reserve in order to expand the amount of woodland. The Beinn Eighe and Loch Maree Islands NNR forms part of the UNESCO Wester Ross Biosphere reserve, and also lies within the Wester Ross national scenic area. The NNR is classified as a Category II protected area by the International Union for Conservation of Nature. The reserve is a Site of Special Scientific Interest (SSSI), and forms part of the Loch Maree Complex Special Area of Conservation (SAC), a European site of international significance, with the Caledonian pinewood, the rich mosaic of upland habitats and the otter population all forming part of the qualifying interests of the SAC designation. The Loch Maree Islands portion of the reserve also forms part of the Loch Maree Special Protection Area (SPA), which hosts the single most important breeding population of black-throated diver in Britain. == References ==
