Aonach Mor


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.
1221 m (4005 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).

Big ridge

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

Aonach Beag and Aonach Mor are the two highest peaks on a long ridge running N-S from the Great Glen to the head of Glen Nevis. The sides of this ridge are generally steep and craggy and it is best to assume that you should only attempt an ascent or descent from the N or S ends of the ridge.

As the N slopes of Aonach Mor are developed for skiing, it is normal to ascend both these mountains from the S via Sgurr a'Bhuic.

An alternative route leads up Coire Giubhsachan to a high col (830m) between Aonach Beag and Carn Mor Dearg. Whilst an ascent of this path is relatively easy, it can be difficult to locate when descending and any deviation will lead you to dangerous crags. If in doubt avoid this route.

Hazards you may encounter on Aonach Mor include
 Crags on or near ascent routes.
 Crags within 1km of 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.
