Avalanche Summary
There have been no reports of avalanche activity since last week when there was a report of a small (size 1) skier accidental wind slab release on a north aspect in the alpine on Thursday. Last Wednesday, several small, skier-triggered avalanches were reported as well as explosives triggered slab avalanches up to Size 3 (stepping down to the late November crust) on wind-loaded slopes in the alpine and at treeline.
Snowpack Summary
A light dusting of new snow now covers a highly variable snowpack surface with hard and soft wind slabs as well as wind-scoured areas of exposed crust in the alpine, and soft unconsolidated snow in sheltered areas at treeline and below treeline. Approximately 5 cm of new snow overlies 20-40cm of old storm snow above the December 15th melt-freeze crust that formed on all aspects and elevations. Recent snowpack tests have ranged from no results, to moderate to hard resistant results on the December 15th layer.Beneath the December 15th layer lies at least 10 cm of sugary snow crystals (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.Some recent conditions reports can be found on the Mountain Information Network (MIN)
