Avalanche Summary
Over the past couple days natural, dry loose avalanches up to size 1.5 were observed on steep south facing terrain.
A few skier triggered dry loose avalanches up to size 1 were also reported. These avalanches were in steep terrain on north aspects.
Snowpack Summary
Exposed terrain in the alpine and treeline is generally wind-affected. In sheltered terrain 10 to 40 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun exposed slopes and a layer of surface hoar on all other aspects
A weak layer of facets from early December is 60 to 120 cm deep.
The base of the snowpack consists of a thick crust with facets or depth hoar in many areas.
