Numerous layers of weak faceted snow throughout our snowpack remain the biggest threat. Drifts and wind slabs formed on top of these Persistent Weak Layers over the last few weeks. These are the locations where you are most likely to trigger an avalanche. The problem is now it's hard to identify the old drifts because they are hidden by the new snow. The photo below is a textbook example of what is possible today.
I don't take chances with buried facets. I've learned they are too unpredictable for my risk tolerance. The simple solution is to stick to slopes less steep than 30˚.
