Avalanche Summary

Numerous wet loose avalanches to size 2 were observed on steep solar slopes the past few days.

Snowpack Summary

15 - 30 cm of new snow from this past weekend has become moist at and below treeline and is refreezing overnight. This along with windslab in the alpine sits on an older melt-freeze crust at all aspects and elevations. The Feb 3rd crust/facet weak layer is buried 60-120 cm deep. Below this, the snowpack consists of a mixture of settled snow and crust/facet layers to ground. Snowpack depths between 80 - 250 cm.
