Avalanche Summary

Snowpack Summary

Around 40cm of low density snow sits on the surface at tree line and below.  In the alpine, we have a mixture of low density snow and wind slabs.  All of this overlies a strong mid pack that is mostly pencil hardness density. The alpine should be approached with caution to sort out whether a slab is present. What is still on our radar is the fact that the strong mid pack is sitting on the december 10  basal facets that covers the bottom 50cm of the snow pack.  Despite the fact that we have not seen recent avalanche activity on the basal facets, if triggered from a thinner area, the potential is for a large avalanche.
