AVALANCHE ACTIVITY:
Dry loose sloughing yesterday on Blackcomb.On Sunday there were a few size 1 dry loose avalanches reported, as well as one size 2 explosives triggered cornice avalanche.
Earlier this month, we saw significant deep persistent slab activity, both natural and human triggered. Deep glide cracks have also been observed previously but appear to be holding together in the cool temperatures.
Snowpack Summary
10-15 cm of new snow sits on a variety of old surfaces. Generally speaking, the new snow sits on firm wind slabs at upper elevations, on a crust below 1900 m and at all elevations on south-facing slopes, and on surface hoar in sheltered areas.
A crust from early December may be found around 200 cm deep in the snowpack. In shallow rocky areas, recent test results suggest that it may still be possible to trigger this layer. In deeper snowpack areas it has shown no recent results and appears to be unreactive in these areas.
