Very little change over the past 24hrs.  Widespread wind affect in alpine terrain. At treeline, pockets of windslabs and persistent slabs overlying the Dec13th crust down 30-50cm. Moderate sheers persist at this interface on a layer of facets above the crust. Crust seems to disappear above 2300m. 1106CR down 120-140cm and is continuing to break down.
