Buried weak layers up to three feet deep are lurking under cohesive snow on many slopes. Easterly-facing slopes at upper elevations are the most dangerous. You may not get feedback from the snowpack like cracking and collapsing before you trigger an avalanche. You can trigger a large avalanche even after crossing a slope multiple times. The best way to avoid this problem is to stick to slopes around 30 degrees without steep slopes above.
