Technically, the English name is a misunderstanding, being named after Lochan na Gaire, the 'little loch of the noisy sound', a loch to be found in the mountain's northeast corrie. Today the lochan is popularly called Lochnagar too. The summit itself may be referred to as Cac Càrn Beag, meaning "small cairn of faeces" in Scottish Gaelic, or less euphemistically, 'little pile of shit'. Peter Drummond, former chairman of the Architectural Heritage Society of Scotland, has also suggested that cac is a corruption of , which would lend a translation of little cairn of the slope. Lochnagar's alternative name, Beinn Chìochan, is probably the original Gaelic name for the mountain.
Geography
Lochnagar is located on the Royal Estate of Balmoral. Its principal feature is a north-facing corrie, around which most of the subsidiary tops, as well as the main peak, sit. The corrie is the location of many classic summer and winter climbing routes. The mountain is a Munro and is popular with hillwalkers at all times of the year, with the most common ascent route being from Glen Muick. Care should be taken on the summit in poor visibility: the plateau has few obvious features and has steep cliffs on its northern edge.
Climate
Lochnagar's summit experiences an Alpine Tundra Climate, with freezing, snowy winters and cool summers. The nearest UK Met Officeweather station is at Braemar northwest. The yearly temperature range is usually between and, but it can be slightly warmer and colder. January has the highest average frosts, despite February nights being colder; January has an average of 26.9 frost days, compared with 24.3 in February. There is the risk of a frost at any time of the year, even in July and August, when each month averages 1 air frost every 10 years.
Due to its location on the Balmoral estate the mountain has many royal links, and Queen Victoria climbed to the summit in 1848. In the film Mrs. Brown, John Brown and Benjamin Disraeli hike up Lochnagar to discuss the need for the Queen to return to active involvement with government. It is also the setting for a children's story, The Old Man of Lochnagar, originally told by Prince Charles. The poet Lord Byron spent time in the area in his youth, and wrote the poem, Lachin y Gair, which also forms the basis of a song: A malt-whisky distillery located near the Balmoral estate on the south side of the River Dee produces the Royal Lochnagar Single Malt whisky.
