The TD Gap, showing how, with care, it is possible to abseil out into Coir a Ghrunnda if the climbing difficulties prove too great. It is also possible to avoid the gap completely by traversing beneath it and ascending the south face of Sgurr Alasdair (Grade 3 scramble).
Scrambling on the WSW Flank of Sgurr nan Eag. A good, but shortish slabby section in the middle leads on to broken ground and a long rough approach to the summit.
The upper section tedium however was lightened by copious carpets of various flowers at around 600-700 metres.
If you are looking to avoid ascending Sgurr Dubh na Da Bheinn enroute to Sgurr Dubh Mor, follow the red line from the foot of Caisteal a Garbh choire. The lower peak can be climbed on returning to the ridge. The route is not completely obvious and not recommended in murky weather.
Climbing on Caisteal a Garbh choire by the South Ridge and West Face. This is by far the roughest and most adhesive rock anywhere in the British Isles. Peridotite knocks southern gritstone into a cocked hat!
For anyone looking to slake their thirst around Coire a Ghrunnda, check out the red dot on this photo. This mossy spring has never dried up to my knowledge and provides the most refreshingly chilled water anywhere high on the ridge. It is only a short descent off of the ridge and for parties considering avoiding the TD Gap it is on the way to a much easier alternative on the south face of Alasdair.
Just before the sun hit the face. In the late afternoon or evening this area gets the full blast of the setting sun.
