Carn Mairg


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.
1041 m (3415 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).

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

Carn Mairg is the highest Munro on the N side of Glen Lyon. The summit, which is rocky and ringed by crags, is located on the rim of Coire Chearcaill and has steep slopes on its S and W flanks.

To the NW a broad ridge connects to Meall a' Bharr and onto Meall Garbh. To the E of the summit a broad ridge connecting to Meall Liath leads down to a coll from where easy slopes continue S to Meall na Aighean.

The terrain of the lower slopes is grass with some rock outcrops, and slopes are moderate to easy inclines with the exception of Coire Chearcaill.

Hazards you may encounter on Carn Mairg include
 Steep slopes 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.

The third and highest of the Invervar 4. The finest view of Schiehallion south face is from here but as Scottish weather can often dictate, it was a bit cloudy at this point. There is a tall cairn on this one. Descending SE from here is steep and navigation is needed when it is cloudy.

Climbed on 19/6/10. After leaving Meall Garbh and snacking on a large slab in the col, I reached my only "other top" of the day - Meall a' Bharr, but this was purely because it was on the way to Carn Mairg. It also has an odd metal structure at its summit. Carn Mairg is reached by a clear path and the crags look higher than the summit as you approach. Great views of Schiehallion's south face. The path I took off the summit towards Meall nan Aighean was steep and crossed a row of boulders and rocks. It looks easier if you head towards Meall Liath before heading south.
