Watch for reactive pockets around ridgecrest and steep rolls. Consider cross-loaded slopes as you move into more exposed and alpine-like features.
Wind slabs may still be triggerable in steep terrain. Practice good travel habits and think about what's below you.

On Tuesday several small dry loose avalanches were reported near Sun Peaks.
Alpine terrain is wind-affected, while sheltered areas have settling snow from recent storms.
A layer of facets, surface hoar, and/or crusts buried in early December is 50-70 cm deep. No avalanches have been reported on this layer since December 19 and it's possible that the recent mild temperatures helped it bond to the rest of the snowpack.
The lower snowpack is strong and settled south of Highway 1, and potentially weaker and more faceted north of Highway 1.
Treeline snow depths vary from 90-150 cm.
