Avoid wind loaded unsupported terrain.
Good skiing can be found in sheltered locations. Look out for wind slabs in immediate lees in steeper terrain.
Avoid wind loaded unsupported terrain.
A variety of crusts with facets above and below exist at the bottom of the snowpack. These layers are going to be with us for a long time and pose a low probability, high consequence situation if triggered.
There was a size 1, and a size 2 wind slab observed on different features of Parkers ridge on December 27th.
Outside the park there have been recent reports of explosive results on the early season crusts producing avalanches up to size 2.5
Strong to extreme winds have redistributed surface snow and scoured windward aspects. Sheltered locations may still hold 15cm of soft snow if winds did not get to it. In protected areas, a weak layer of 7mm Surface Hoar may be 10-30cm down. The mid pack is mostly made up of facets. At the bottom of the snowpack there are multiple early season crusts with facets above and below.
