High

Avalanche Summary

Avalanche activity on Saturday was mostly reported as loose wet size 1-2 from steep terrain facing the sun.

Snowpack Summary

Surface snow is likely a supportive crust or moist snow at all elevations except high north facing. Weak faceted grains sitting a crust formed in early February are now buried 100 to 150 cm. This layer has generally been gaining strength, however it is still occasionally producing large avalanches at upper elevations where supportive crusts have not formed above it.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
