Avalanche Summary
No new avalanches were reported on Friday. Several small wind slab avalanches were reported earlier in the week, and lingering wind slabs may still be reactive in isolated wind-loaded pockets.
Snowpack Summary
Up to 5 cm of new snow covers a variable surface with a mix of soft wind slabs, hard wind slabs, sastrugi, faceted snow, and even some surface hoar. Last week's winds reverse loaded many terrain features and formed stubborn wind slabs on a surprising range of aspects. An interface of faceted (sugary) snow and surface hoar was buried on Boxing Day and can be found up to 100 cm deep. Recent observations suggest the snow has bonded well to this interface. Snowpack layers below this interface are also generally well bonded.
