    Around 50-80 cm of snow sits above a weak layer of surface hoar. This layer is most likely found in shaded and sheltered areas between 1700 m and 2000 m.

Confidence

Moderate - Due to the number of field observations

Snowpack Summary

15-30 cm of new snow with moderate southwesterly winds is sitting on a crust on all but northerly aspects, wind-affected surfaces in the alpine, and possibly a mixture of weak feathery surface hoar and/or sugary facets in sheltered terrain at treeline and below.A crust that recently formed right to mountain top on southerly aspects and on all aspects below 1700 m is now buried 50-80 cm deep. Additionally at this depth, feathery surface hoar may be found in shady sheltered areas at treeline. The remainder of the snowpack is generally well-settled and strong.
