The November Persistent Weak Layer of sugary facets (DETAILS HERE) showed its cards again on Saturday with the remotely triggered avalanches described above. My partner and I continued to experience collapsing (whumpfing) of the snowpack while traveling on skis. Recent avalanches and collapsing are NOT signs of a stable snowpack. They are actually red flags of avalanche danger. They are bullseye clues that the snowpack is unstable and capable of producing more avalanches. Continue to avoid steep slopes for a while until the snowpack is stable.
