An Stac


Quick Facts
This is the height of the mountain above sea level. However, on the climb, it is the ascent that matters, i.e. the sum of all the uphill parts of the route.
814 m (2670 ft)

This is the standard notation used on Ordnance Survey Landranger maps.

Each reference consists of two letters identifying a 100,000 metre square block then three digits defining the Easting and finally the three digits defining the Northing with reference to the South West corner of the block.

NN166712 is the grid reference for the summit of Ben Nevis. Where you are given the map number ( For Ben Nevis = 41) it is acceptable to omit the two initial letters e.g. 166712. (Instructions on how to read the references are given on the OS maps).

Mountain names are usually in Gaelic, the native language of the Scottish Highlands, or have been derived from the old Scots and Norse languages. We give the most commonly accepted meaning, but accept that some of these are disputed.
The stack

A description of the characteristics of the mountain including any hazards of which you should be aware.

The head of Coire a' Bhuiridh, which lies just to the E of Loch Ailort is formed by 6 significant peaks, 3 of which are deemed to be Corbetts. These are An Stac, Rois-Bheinn (882m) (Corbett), and Sgurr na Ba Glaise (874m) (Corbett) and consequently they are climbed as a group.

An Stac is the most distinct peak, where as Rois-Bhein and Sgurr na Ba Glaise lie on a ridge running from Rois-Bheinn in the W to An t-Slat-bheinn in the E, where the ridge then turns NNE to Beinn Coire nan Gall.

These hills are not well supplied with access paths so the routes tend to go from top to top. An Stac is a steep sided conical hill with many rocky out crops.

Hazards you may encounter on An Stac include
 Steep slopes on or near ascent routes.
 Crags on or near ascent routes.
 Crags near summit.
General Considerations
 Temperature decreases by 1degree C for every 100m of ascent.
 Wind usually increases with altitude.
 Visibility can change markedly with cloud level.
 River/Stream levels can increase markedly in one day.
