Dangerous avalanche conditions exist. You can trigger an avalanche on several weak layers and it can grow into a destructive and likely unsurvivable avalanche. If you decide to travel in avalanche terrain be aware that you are threading the needle. You can reduce your chances of triggering an avalanche by traveling on south and southwest-facing slopes with supportable crusts underneath the new snow. If you don't want to thread the needle you can always stick to slopes less than around 30 degrees steep without similarly steep slopes overhead.
