Keep decision making conservative as weak layers remain a concern.
Choose smaller, low angle slopes free from overhead hazard.
Winds have picked up and loose snow is available to build fresh and reactive wind slabs.
Small wind slabs could step down to deeper weak layers producing very large avalanches.
While this layer is becoming less likely to be affected by a rider, if triggered, a large and destructive avalanche is certain. Avoid areas where the snowpack thins, like steep, rocky start zones. Weak layers are more easily triggered here
Explosive control work continued on Thursday, producing numerous avalanches up to size 4 (very large). While natural activity appears to have tapered off now, human triggering is still a concern.
A notable size 3.5 avalanche was remote-triggered from a ridgeline in the Bonningtons on Tuesday, see the photo below.
And check out this photo blog of recent avalanches throughout the province.
Surface conditions include settling storm snow, sun crusts on south facing slopes, and lightly wind-affected snow at higher elevations.
A widespread crust is buried 100-150 cm deep with a layer of weak facets above (and/or surface hoar in isolated sheltered terrain). This continues to be the layer of concern throughout this region, as it continues to produce very large avalanches throughout this region.
The snow below the crust is generally strong and well bonded.
