Kernpunkte

Fresh storm slabs may be primed for human triggers. Start in simple terrain to test the bond of the new snow.

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

Snowpack Summary

15-30 cm of new snow with moderate southwesterly winds have covered a variety of snow surfaces. These include crusts on all but northerly aspects, wind-pressed surfaces on northerly aspects in the alpine, and a mixture of surface hoar (weak feathery crystals) and surface facets (sugary grains) in terrain sheltered from wind/sun at treeline and below.Around 50-80 cm down is a melt-freeze crust to mountain top on southerly aspects, a crust below around 1700 m on all aspects, and feathery surface hoar in areas sheltered by the wind/sun at treeline elevations. The remainder of the snowpack is currently well-settled and strong in most locations.
