The base of our snowpack consists of a foot or more of loose sugary faceted snow grains. On top of that we have a few layers that are a bit stronger. This is an unstable set up and we are adding more layers on top. If we see a foot of snow and a little bit of wind, the dangerous situation will get more dangerous. Human triggered avalanches will be almost certain.
