The situation seems secure, but take care of any instability point.
Supervise conditions change. Be careful!
8-22 points
Suspicious situation. Go very cautious on this road. Avoid crossing set and go from one shelter to another.
23-55 points
Not a good situation. It's far better to abandon this route. Approach route only if you are very experienced.
IN ANY CASE:
- Never enter a restricted area.
- Do not go alone.
- See weather conditions, forecast and local information about avalanches.
- Use appropriate materials and check their status.
- Tell someone what route you go.
- Follow advice from an experienced, well acquainted with the area you want to travel.
- Do not walk in groups, only one behind the other, keeping a safe distance.
- Announced if you will arrive later
- Request information from professionals: mountain rescuers, guides, monitors ski, mountain gendarmes.
Consider that there is NO safe area!
