Avalanche Summary
On Sunday, a Size 1 storm slab was reported in the north of the region - on a steep, unsupported convex roll. Otherwise, no new avalanches observed.
Snowpack Summary
Approximately 40-60 cm of snow from late last week now sits on top of a rain crust (or multiple crusts) that formed during the wet weather at the end of November. The snow appears to be bonding well to the crust with no avalanche activity reported recently on this layer.Up high, the main concern has been winds (first from the south, and more recently from the north) that have blown snow around in exposed areas creating drifts and scoured areas. The take-home message is that wind slabs can be found on many aspects at higher elevations - including some southerly aspects, which is an unusual pattern. Other than steep south facing slopes, much of the riding in the region consists of 20-30cm of low density snow that is right-side up (the snow gets more dense as you go deeper into the snowpack).
