    Hard and soft wind slabs exist on most aspects in the alpine and exposed treeline areas, and may still be reactive to light loads such as a skier or rider. Watch for new wind slab development with new snow and wind forecast for Wednesday.

Avalanche Summary

Snowpack Summary

A light dusting of snow covers a medley of surfaces which include stubborn wind slabs and wind-scoured exposed crust in the alpine, and soft unconsolidated snow in sheltered areas at treeline and below. Up to 40cm below the surface you'll likely find a widespread melt-freeze crust that was buried on December 15th. Recent snowpack tests have ranged from no results, to moderate to hard resistant results on this layer.Beneath the December 15th layer lies at least 10 cm of sugary facets and the late November crust, which is now buried 70-100 cm with a thin layer of facets above. Beneath this crust the lower snowpack is well settled.
