Avalanche Summary
Explosive control on Sunday produced two size 1.5 storm slabs from high, north-facing alpine terrain in the west of the region.
No natural or rider-triggered avalanches have been reported since Saturday.
Snowpack Summary
New snow accumulates on a robust crust or moist snow at all elevations except high north-facing.
Weak faceted grains sitting on 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 a supportive crust has not formed above it.
