Ski touring in the Cairngorms

Today the weather was glorious: but i was working indoors.
Yesterday i took Jim and Ann on a day of introductory ski touring. We went up to the summit of Cairngorm and over to Ben Macdui and then back to the car park via Lurchers Gully. The visibility was absolutely zero all day and snow fell on a moderate to gentle wind all day (today was wall to wall sunshine and snow in contrast). We covered kick turning, avalanche awareness (we actually met the SAIS on the top of Cairngorm and had a brief chat with them also). We also looked at safe, cautious 'survival' skiing techniques for zero vis and zero contrast. Fortunately Ann and Jim are quite strong skiers and coped fine with me out in front to break up the surface of the snow and give the ground some definition.
The ski touring will now be good for several weeks and the time for the big 4000ers tour is now as the snow settles down, visibility is good and there is deep snow on all parts of the Cairngorms. Sadly i'm working indoors till the weekend.
Here are some pictures of the zero vis for what they are worth and some shots from earlier in the week in Glen Torridon area.
