Sgurr Mhor (Beinn Alligin)


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.
986 m (3234 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.

Sgurr Mor is the highest peak on Beinn Alligin and is a very distinctive mountain with its great cleft, the Eag Dubh, on its S face.

From the summit a ridge runs SW, curving S to a col below the rocky slopes of Tom na Gruach. The col is the normal ascent route, either from Tom na Gruach or from Coire Toll a Mhadaidh Mor to the E.

To the E of the summit a craggy ridge leads to Na Rathan with its rocky crest. This ridge is known as the Horns of Alligin. A traverse of the Horns, which requires scrambling, leads to a descent into Bealach a' Chomla.

Beinn Alligin is a relatively steep sided mountain with much of its slopes formed of terraced layers of red sandstone which erode to a rounded profile making hand and footholds difficult.

Hazards you may encounter on Sgurr Mhor include
 Steep slopes on or near ascent routes.
 Crags on or near ascent routes.
 Crags near summit.
 Narrow Ridges, with exposure.
 Scrambling (minor), easy hand and footholds.
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.

A great mountain with some stunning views. The Eag Dubh gully is jaw dropping as you round the ridge. The horns were good fun but getting off them was tricky if you try to come off in a straight line from where the path fades over the rock slab area. I would recommend doing this route in reverse.

Did this walk early Sept 2008. Set off from car park at 9am on a sunny Tuesday morning with Gill and a sack of chocolate, bananas and factor 15 sun cream. Weather was a s good as I've ever had on Scotland's mountains as we did clockwise traverse. Have to say it's a great ridge walk when weather is clear, you can see every step of the ridge from either summit and the views are fantastic. The drop of Tom na Gruach summit was a wee bit tricky with steep cliffs to the south but well worth the effort once on the ridge. Back to the Old Inn at Gairloch for well deserved beer afterwards, a great walk.
