You can trigger a dangerous avalanche on steep slopes that face northwest through north to east. The most dangerous slopes are near and above treeline, generally above 10,000 feet, facing these directions. You can trigger one of these avalanches from a distance so be aware of steep slopes above you and where you stop to rest or regroup. You can dramatically decrease your chances of being caught in an avalanche by avoiding slopes steeper than about 30 degrees on these aspects of concern, or move to south or west-facing slopes.
