A Persistent Weak Layer of sugary facets that formed in mid November is by far our biggest threat right now. Collapsing of the snowpack under foot is a regular occurrence during my fieldwork. The buried Persistent Weak Layer fails and you can actually feel the snow drop underneath you during some of these collapses. This is the same thing that happens when an avalanche releases. The only difference is that I am not on slopes that are steep enough to slide. This is the key to staying safe out there right now. You need to avoid being on or below steep slopes.
