Buried layers of weak, faceted snow continue to plague our snowpack near and above treeline on northerly facing slopes. Above treeline, thick, hard slabs 2-4 feet thick sit on top of these persistent weak layers. Although the likelihood for triggering a deep and dangerous avalanche has significantly decreased, all it takes is finding the right trigger point such as a shallow, rocky area or thin spot over a convexity. There are many slopes out there now where you can get away with it, but when it comes to life and death, I don't want to just get away with it, I want to know that it's good to go. For that reason, I'm continuing to avoid steep northerly aspects.
