Choose an able leader. Appoint a competent tail-end Charlie – not the slowest/poorest skier! Invariably the best skiers want to be up front putting in fresh tracks.
Grading and Difficulty
There are several well-established systems used for grading ski mountaineering and off-piste skiing objectives. The Swiss, French, German, Italian and Austrian Alpine clubs have adopted these, or variations of them, for use in their guidebooks. Two widely used grading systems are the Blachère and Traynard scales, which are described below and have, more or less, been incorporated into this guidebook.
Blanchère Scale
On tours where skiing rather than Alpine climbing skills are required the following adjectival grades are used (see table below).
The Blanchère scale has been used in this guidebook. Invariably this means that the equipment carried must include rope, crampons, ice axe and the means to ensure safety on steep terrain and glaciers. This roughly relates to mountaineering grades as: SAM = F (facile); BSA = PD (peu difficile); TBS = AD (assez difficile). The mountaineering grades of D (difficile), TD (très difficile) and ED (extrêment difficile) were not covered by the Blanchère scale and have traditionally been relegated to the realms of Extreme Skiing.
