In reply to Jamie B:
At the top of the scree off to the right straight up from the water slide. If it wasn't for the clag you could see the rannoch wall and curved ridge behind, central buttress is off to the left. Ignore the summer route, somewhat subjective I suppose but that's the way I've always done it, what I marked as the winter approach was a lovely long pitch of grade III water ice that day (had to down climb half of it to get back down!). It will have been climbed before just wondered if it had a name etc.
