The most obvious feature in the corrie from a skiing point of view, is The Great Stone Shoot. This wide corridor separates Sgurr Alasdair from Sgurr Thearlaich, and the spine of the main ridge. The top of the gully is a narrow col, and in winter, forms an arete which is unlikely to ever form much of a cornice. On a clear day, the views out to sea over Coire a' Ghrunnda are superb.
Optimum conditions would allow a descent all the way to the lochan at 560m a.s.l., giving you over 400m of vertical. The gully gets its name for a reason - there are a lot of stones in it, and getting enough snow to cover them is critical. However, it happens more than people expect. Getting enough snow cover all the way to the lochan is harder, and it is likely that timing your visit to coincide with this will be more taxing than the actual descent itself!
It is easiest to ascend the gully first, rather than approaching along Sron na Ciche or from the main ridge. The slopes below the gully are at least as steep as the gully itself, and this is one of the easiest Grade I gullies you are likely to ski. It is in the most part at least 15m wide, and rarely exceeds 30 degrees. It's a fine outing, and comes highly recommended.
