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. The upcoming heatwave will likely increase the sensitivity of these weak layers, and the rewards just don't outweigh the risks for me.
