Avalanche Summary
No new avalanches were reported in this region on Tuesday.
Snowpack Summary
Expect to find sun crusts on steep solar aspects. The old wind slabs created over the weekend are faceting and becoming less reactive to human triggers.A crust/surface hoar layer buried mid-January is now roughly 80-140 cm below the surface, and still has the potential to be triggered from a thin snowpack spot, or with a large trigger like a cornice fall.It is unlikely, but may still be possible to trigger very large avalanches on facets at the bottom of the snowpack in steep, rocky, and shallow snowpack areas or with large triggers.
Problems
Wind Slabs
Wind slabs are becoming less likely to human trigger. Steep, convex, and rocky areas are the most likely spots to trigger these lingering wind slabs.
Use ridges or ribs to avoid pockets of wind loaded snow.Avoid steep, rocky, wind effected areas where triggering is more likely.
Aspects: All aspects.
Elevations: Alpine, Treeline.
