Avalanche Summary

No new avalanches have been observed the past few days but some older wet loose and wind slab avalanches are still visible.

Snowpack Summary

A few cm of new snow sits over widespread wind effect at all elevations. Exposed windward slopes are scoured to crust and sastrugi is common in open terrain. On northerly aspects there is less wind effect. Recent warm temps and solar input have moistened the surface snow at treeline and below. Beneath this, 30–50 cm of settled snow overlies crusts and facets. The lower snowpack is generally well settled.
