Avalanche Summary

Avalanche activity on Sunday and Monday was reported as a few loose wet size 1-2 from steep alpine.

Snowpack Summary

There may be 10-30 cm of new snow sitting on the surface. This likely sits on a supportive crust or moist snow at all elevations except high north facing slopes. Weak faceted grains sitting a crust formed in early February are 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.
