Snowpack Discussion

Snow continues through the day which could add up to 40cm on top of 20 cm of recent snow. This snow sits on a crust on solar aspects and all aspects below 1800 m. Above the crust, surface hoar or facets exist in sheltered areas and on north aspects.

Two concerning weak layers are present in the mid snowpack: facets/surface hoar or a crust from mid-February buried 50-90 cm, and facet/surface hoar/crust from late January buried 80-120 cm.

Avalanche Activity

On Monday: A few natural and skier triggered storm slab and wind slab avalanches were reported up to size 2.5 (very large). They happened on north and east aspects in the alpine and at treeline.

Some of these avalanches stepped downto weak layers that are buried in the snowpack.
