Avalanche Summary

On Saturday, a few wet loose avalanches to Size 1.5 were reported on steep south and west aspects. Last week, a few size 3 natural avalanches were reported on steep north (east) facing alpine faces in the Selkirks and also near 2500m east of Rogers Pass. The failure layers are unknown, but likely an early season crust.

Snowpack Summary

Daytime warming has only had effects on steep sunny slopes. With decreasing temperatures and some thin cloud, the sun's effects will be minimal. Crusts from late November have been showing reasonable bonding in snowpack and slope tests. Isolated wind slabs may still be found behind ridges and ribs, primarily on north through east aspects. Below treeline, the snowpack is shallow--look out for early season hazards like open creeks and tree stumps.
