Ben Nevis - Navigation and Safety

Navigation and Safety

Ben Nevis's popularity, climate and complex topography contribute to a high number of mountain rescue incidents. In 1999, for example, there were 41 rescues and four fatalities on the mountain. Some accidents arise over difficulties in navigating to or from the summit, especially in poor visibility. The problem stems from the fact that the summit plateau is roughly kidney-shaped, and surrounded by cliffs on three sides; the danger is particularly accentuated when the main path is obscured by snow. Two precise compass bearings taken in succession are necessary to navigate from the summit cairn to the west flank, from where a descent can be made on the Pony Track in relative safety.

In the late 1990s, Lochaber Mountain Rescue Team erected two posts on the summit plateau, in order to assist walkers attempting the descent in foggy conditions. These posts were subsequently cut down by climbers, sparking controversy in mountaineering circles on the ethics of such additions. Critics argued that cairns and posts are an unnecessary man-made intrusion into the natural landscape, which create a false sense of security and could lessen mountaineers' sense of responsibility for their own safety. Supporters of navigational aids pointed to the high number of accidents that occurred on the mountain (between 1990 and 1995 alone there were 13 fatalities, although eight of these were due to falls while rock climbing rather than navigational error), the long tradition of placing such aids on the summit, and the potentially life-saving role they could play. A series of solidly-constructed cairns currently (September 2009) marks the upper reaches of the Pony Track.
