Use extra caution at treeline.
There is some uncertainty in the distribution of buried surface hoar. In areas where surface hoar exists it is most likely to be preserved at treeline.
Up to 35 cm of recent snow will have formed a storm slab at all elevations. The largest slabs will be found on wind loaded terrain in the alpine. This new snow could overlie a surface hoar layer at treeline which it likely won't bond well to.
A few size 1 natural wind slab avalanches were reported in the north of the region. These avalanches were in the immediate lee of ridge features.
Up to 35 cm of recent storm snow will have formed storm slab. The largest slabs will be found on north and east aspects in the alpine. This new snow will overlie large surface hoar at treeline and a crust below treeline.
check out this great MIN from Shames.
The mid pack contains several crusts from November. In general, the mid pack is well settled. The height of snow at treeline is around 150 cm and tapers rapidly below treeline.
