Avalanche Summary
There have been no reports of avalanche activity since the weekend when a small, natural, wind slab avalanche was observed on a north-facing, alpine, ridge-top feature on Saturday. Prior to that, several natural loose, wet and wet slab avalanches up to size 2 were observed on solar aspects at treeline and above.
Snowpack Summary
Warm temperatures have created a spring-like, melt-freeze crust on all aspects which will likely to become moist in the afternoon on steep, sun-exposed slopes. On north aspects this surface crust is 1-2 cm thick, with dry, sugary snow crystals (facets) below. Beneath the surface, the upper snowpack is well settled and overlies a thin layer of facets on 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.
