Windslabs persist in leeward slopes. Sheltered areas may offer the best chance for finding soft turns,
Multiple crusts from earlier in the season are still present near the bottom of the snowpack and have the potential to be unstable. Consider digging down and having a look in the area you are skiing or riding in.
Recent winds have created windslabs in leeward features. Avoid wind loaded pockets and evaluate carefully before entering steep and unsupported terrain that could be affected by wind. Windslab avalanches may step down to deeper layers.
A variety of crusts with facets above and below exist at the bottom of the snowpack. These layers are going to be with us for along time and pose a low probability, high consequence situation if triggered.
One natural size 2 avalanche, failing on the early season crust, and two natural size 2 windslabs were observed on alpine southwest and south aspects on Monday, December 9th near the Icefields.
Throughout the week moderate to strong winds at treeline and above have redistributed up to 20cm of snow into windslabs. There is a surface hoar layer that has been found in sheltered Alpine areas down 40-60 cm's. At the bottom of the snowpack there are a variety of early season crusts with large faceted crystals above and below. Both of these layers have been producing sudden planar, compression test results in test profiles.
