Avalanche Summary
A few small loose point release avalanches observed on a field day around Parker Ridge.
Snowpack Summary
Warm temperatures are making the surface snow moist below 1900m and on south facing terrain. The Icefields has wind effect even into treeline while the Bald hills have had noticeably less. In sheltered areas there is roughly 15cm of snow overlying the January 30th layer which is a temperature crust or wind slab depending on the area. The midpack is weak and faceted. The bottom of the snowpack is comprised of large depth hoar.

Problems
Wind Slabs
These windslabs may be sitting on top of facets or the January 30th crust.
Aspects: All aspects.

Deep Persistent Slabs
Large depth hoar at the bottom of the snowpack. These layers are going to be with us for a long time and pose a low probability, high consequence situation if triggered.
