Athough recent winds have been from the north, northeast, and east, there is definitely evidence of cross-loading, with drifts possible on all aspects. Most of the wind drifts we were finding below 9300' were shallow, but we were also finding pockets of hard fresh drifts up to 15 cms thick, sitting on top of the weak, very low-density snow that fell on Thursday and Friday. The wind slabs should relax somewhat by Saturday, but may still be reactive as they are on top of such weak snow.

Have been looking at some thinner snowpack areas over this past week, and am finding several areas with weak, faceted snow underneath the storm snow that has fallen over this past week. Other than areas that had already avalanched (portions of Cardiac Bowl and Cardiac Ridge), I have been finding weak snow in the bottom 30-45 cms of the snowpack in thinner snowpack areas on aspects facing northwest through east. These thinner snowpack areas have likely been undergoing faceting over the recent 7-10 day period of colder conditions, leading to mid-pack facets above the October basal facets/depth hoar at the ground. In areas we were looking at today I could not identify a stronger slab on top of the weaker facets, but the weak structure is in place for possible future problems once the snowpack gets additional loading from wind and/or storm snow. (Our observation today definitely aligned with a 12/27 observation the UAC received.)
