Snowpack Summary

Surface snow has been facetting during this period of cold weather, and last weeks storm snow has been settling slowly. Areas sheltered from the wind may be developing a new surface hoar layer. The mid-november crust is buried down 100-180 cm and produces variable results in snowpack tests. Moderate results may be more likely in shallower snowpack areas, and deeper snowpack areas may be more likely to show no results on this layer. Professionals continue to monitor the crust for facet develop that may provide a weak layer above a hard sliding surface in the future.
