Avalanche Summary
There have been no reports of avalanche activity since last week when numerous small to large loose wet avalanches up to size 2 were observed on solar aspects. Also a small natural wind slab avalanche in steep terrain on a northerly aspect in the alpine on Saturday. Warming and cloud cover on Sunday produced pinwheeling and snowballing on all aspects.
Snowpack Summary
Warm temperatures have created a spring-like, melt-freeze cycle on all aspects with the overnight crust becoming moist in the afternoon on sun exposed slopes. On north aspects the surface crust is 1-2 cm thick with dry, sugary snow crystals (facets) below. Beneath the surface crust the upper snowpack is well settled and overlies a thin layer of facets above the late-November rain crust. Recent snowpack test have found hard, sudden compression test results on the facets just above the crust, which is now buried between 60-100 cm at treeline elevations. Beneath this crust the lower snowpack is well settled and consists of several crusts that formed in the early season.
