Avalanche Summary

No new natural avalanche activity was observed.

Snowpack Summary

20-30 cm of storm snow is overlying a buried wind slab. This new snow and the buried wind slab down 50cm are both reactive to snow pit tests in the Alpine. These two layers are certainly a concern for triggering. The November 12th melt-freeze crust is now 40-60cm down from the surface and is still showing a good bond with the snow above.
