In common with other approaches on this side of the mountain, it has the advantage of giving an extensive view of the cliffs of the north face, which are hidden from the Pony Track. The north face of Ben Nevis is riven with buttresses, ridges, towers and pinnacles, and contains many classic scrambles and rock climbs. It is of major importance for British winter climbing, with many of its routes holding snow often until late April. It

(Grid references may be written with or without spaces; e.g., also NN166712.) NN has an easting of 200 km and northing of 700 km, so the OSGB36 National Grid location for Ben Nevis is at 216600, 771200. Grid references may also be quoted as a pair of numbers: eastings then northings in metres, measured from

According to the observations carried out at the summit observatory from 1883 to 1904, fog was present on the summit for almost 80% of the time between November and January, and 55% of the time in May and June. The average winter temperature was around −5 °C (23 °F), and the mean monthly temperature for the year was −0.5 °C (31.1 °F). In an average year

Subsequently, the John Muir Trust cleared a number of smaller informal cairns in 2016 which had been erected by visitors, which were seen as dangerous as they could confuse walkers using them for navigation.

5168-447: The words nèamh meaning 'heaven' (which is related to the modern Scottish Gaelic word neamh meaning 'bright, shining') and bathais meaning 'the top of a man's head'. Thus, Beinn Nibheis could derive from beinn nèamh-bhathais , "the mountain with its head in the clouds", or 'mountain of heaven'. The Scottish Gaelic word neimh can be translated as 'malice', 'poison' or 'venom', yielding 'venomous mountain'. As
5244-417: The world to study the weather at high altitude. In the summer of 1881, Clement Lindley Wragge climbed the mountain daily to make observations (earning him the nickname "Inclement Rag"), leading to the opening on 17 October 1883 of a permanent observatory run by the SMS. The building was staffed full-time until 1904, when it was closed due to inadequate funding. The twenty years worth of readings still provide
5320-539: The year. Ben Nevis is all that remains of a Devonian volcano that met a cataclysmic end in the Carboniferous period around 350 million years ago. Evidence near the summit shows light-coloured granite (which had cooled in subterranean chambers several kilometres beneath the surface) lies among dark basaltic lavas (that form only on the surface). The two lying side by side is evidence the huge volcano collapsed in on itself creating an explosion comparable to Thera ( 2nd millennium BC ) or Krakatoa (1883). The mountain
5396-485: Was "the climax of a magnificent week's climbing by Smith and Marshall, and the highpoint of the step-cutting era". The history of hill running on Ben Nevis dates back to 1895. William Swan, a barber from Fort William, made the first recorded timed ascent up the mountain on or around 27 September of that year, when he ran from the old post office in Fort William to the summit and back in 2 hours 41 minutes. The following years saw several improvements on Swan's record, but
5472-418: Was completed by Dave MacLeod in 2008 after two years of preparation. The north face is also one of Scotland's foremost venues for winter mountaineering and ice climbing and holds snow until quite late in the year; in a good year, routes may remain in winter condition until mid-spring. Most of the possible rock routes are also suitable as winter climbs, including the four main ridges; Tower Ridge, for example,
5548-766: Was considered the hardest route on the mountain, is described by W. H. Murray in Mountaineering in Scotland – and, on Càrn Dearg , Centurion and The Bullroar (both HVS), Torro (E2), and Titan's Wall (E3), these four described in the SMC 's guide as among "the best climbs of their class in Scotland". Many seminal lines were recorded before the First World War by pioneering Scottish climbers like J. N. Collie, Willie Naismith, Harold Raeburn , and William and Jane Inglis Clark. Other classic routes were put up by G. Graham Macphee, Dr James H. B. Bell and others between
5624-517: Was covered by BBC Scotland. On 6 May 2019, a team of highliners completed a crossing above the Gardyloo Gully, a new altitude record for the UK. Also in May 2019, a team of 12, led by Dundee artist Douglas Roulston carried a 1.5-metre (4.9-foot) tall statue of the DC Thomson character Oor Wullie to the top of the mountain. The statue, which had been painted by Roulston with a 360-degree scene of
5700-410: Was in the region to collect botanical specimens. Another early ascent was in 1774 by John Williams, who provided the first account of the mountain's geological structure. John Keats climbed the mountain in 1818, comparing the ascent to "mounting ten St. Pauls without the convenience of a staircase". The following year William MacGillivray , who was later to become a distinguished naturalist, reached
5776-404: Was one of the first places in Scotland to receive the attention of serious mountaineers; a partial ascent and, the following day, a complete descent of Tower Ridge in early September 1892 is the earliest documented climbing expedition on Ben Nevis. (It was not climbed from bottom to top in entirety for another two years). The Scottish Mountaineering Club's Charles Inglis Clark hut was built below
