Unusual and far from safe avalanche conditions exist. The most dangerous slopes face west through north to southeast, generally near and above treeline. Here, you can trigger an avalanche that can easily grow large enough to bury you. You can trigger them from a distance, so be aware of steep slopes above you and other parties nearby. You may not experience obvious signs of instability, such as cracking and collapsing in the snow, before you trigger a large and destructive avalanche, so don't think a lack of these signs means it's safe. You may find safer terrain on south and southwest-facing slopes, but the easiest way to increase your safety margins is to avoid traveling on or underneath slopes steeper than about 30 degrees on aspects of concern, especially near and above treeline.
