Those smug baggers among grough’s readership who are resting on their Munro laurels may have to get their boots back on.

Surveyors have been drafted in to see if two Scottish peaks can be added to the 284 which already qualify as 3,000-footers.

Foinaven and Beinn Dearg, both in the North of Scotland, fall tantalisingly short of the magic metric equivalent of being 914.4m high. They are recorded on Ordnance Survey maps as 914m in height, just 40cm short of Munro status.

Now the Munro Society has called in an independent surveying company to ascertain the exact height of the two mountains. Two surveyors will accompany society members and various interested mountaineering bodies up the two peaks. If the hills measure up, the society’s 3,000-plus members, all of whom have bagged the 284 current Munros, will have to boot up and conquer the two extra mountains.

CMCR, a survey company based near Falkirk, will do the work employing the latest techniques. Surveyors using Global Positioning System equipment can now achieve an accuracy of within one centimetre. This should be good enough to satisfy the Scottish Mountaineering Club, the official keeper of Munro records, which will not alter its tables, first published in 1891, without a surveyor’s confirmation.

Beinn Dearg, north of Torridon, will be measured on 21 and 22 April and Foinaven, in Sutherland, on 12 and 13 May.
