Snowpack Discussion
On Thursday, 20 to 30 cm of new snow fell, accompanied by moderate southwest winds, forming new storm and wind slabs. Since last Saturday, up to 90 cm of storm snow has accumulated, sitting on a hard melt-freeze crust and surface hoar crystals in wind-sheltered areas.
Weak layers of surface hoar and/or faceted grains, buried in mid-February and late January, are found 60 to 150 cm deep.
The lower half of the snowpack remains strong.
Avalanche Activity
Many small to large (size 1 to 3) storm, wind slab, and cornice avalanches were either triggered naturally, by humans, or by explosives on Wednesday. These occurred at treeline and alpine elevations primarily on north aspects. Most slabs were 50 to 80 cm deep.
With new snow and daytime warming, human-triggered avalanches will be very likely on Friday.
