Snow Characteristics Comments
Slopes on the southern half of the compass had a stout melt-freeze crust. Didn't see much northerly-facing terrain, but sheltered slopes below treeline appeared to be a mix of soft creamy snow and at lower elevations with less than 20cm of snow depth, the snowpack appears to be almost completely faceted.

Poor Snowpack Structure
Red Flags Comments
Persistent grains at the base of the snowpack as well as below a stout crust could(will?) become a problem with additional snow.

Comments
The snow in the alpine zone is.... quite rare. But in protected pockets like this wind drift near a ridgeline, we can see a little bit of structure. The most obvious is the stout, ~6cm melt freeze crust that has been forming during the warm sunny days. This crust offers surprisingly predicable skiing and sort of has the texture of a pumice stone (easy to skin up). Got some failures in column tests, but hard to translate this to avalanche activity. The crust(s) are adding strength and bridging over the possible weak layers. Of note- I noticed a very thin layer of sugary snow underneath the crust- I imagine there will be more development of facets above and below this crust and will be another interface to keep an eye on (if we ever get more snow??)
