I've not descended from Bealach Sneachda, so can't advise based on personal experience (although there certainly looks to be a feasible line from everything I see on the map). However, if you want to see aerial photos that aren't covered in snow, then Bing Maps tends to be much more helpful than Google Maps - and so is the case here (Bing just has a thin line of cornice remaining).

If you use the OS map layer on Bing Maps to find the location you're interested in, you can then switch to the Satellite layer to view the same location - and helpfully the Munro summits are also marked on the Satellite layer so, in this case, it's easy to orientate yourself.
