Mullach nan Coirean
or Sgùrr a' Chaorainn is one of the Mamores mountains in the Scottish Highlands. It reaches a height of 939 metres and is the most westerly of the ten Munros in the Mamores. It has a lower peak to the west, Meall a' Chaorainn. To the east, it is linked to the neighbouring mountain Stob Bàn by a bealach at a height of 846 metres; these two Munros are often climbed together from Glen Nevis.
Landscape
Mullach nan Coirean stands in stark contrast to the adjoining Stob Bàn, which is a pointed and light-shaded peak, owing to its crown of quartzite. Mullach nan Coirean is a large sprawling mountain of ridges and corries, with its granite rock giving it a red shade. The mountain has three north-facing corries: the finest of these is Coire Dearg which is drained by the Allt a' Choire Dheirg into Glen Nevis and is overlooked by Mullach nan Coirean’s South East Top which is listed as a "top" in Munro's Tables. The South East Top was previously called "Coire Dearg Top" but was changed to avoid confusion as the main summit also overlooks Coire Dearg. The other two northern corries are smaller: Coire Riabhach also drains to Glen Nevis while Coire a’ Mhuillinn empties further west into the River Kiachnish which delineates the mountain's western boundary. A fourth corrie, Coire Carach stands on the mountain's southern slopes.Mullach nan Coirean has four ridges radiating from its summit. The eastern ridge links to the adjoining Munro of Stob Bàn, which is three kilometres away, whilst the south western ridge links to the subsidiary top of Meall a' Chaorainn before descending steeply to the glen of the River Kiachnish. The northern ridge is four kilometres long and has the vitrified fort of Dùn Deardail near its end, just before it joins Glen Nevis. The fort is probably named after Deirdre, the princess of Ulster, and is one in a line of vitrified forts that stretches from Craig Phàdraig to the west coast. The northeast ridge also descends to Glen Nevis but is much shorter. The mountain's lower northern slopes are covered by the coniferous woodland of the Nevis Forest.
