Avalanche Summary
Early on Friday a few natural slab avalanches to size 2 were reported in storm snow above 1900 m. Explosive control was able to release similar avalanches.
Snowpack Summary
Between Monday and Friday, 70-100 cm of storm snow accumulated in the region. Below the new snow from this week lies the Boxing Day interface which consisted of wind affected surfaces, faceted (sugary) snow, or surface hoar. Recent observations suggest the overlying snow is generally well bonded to this interface. Recent weaknesses in the snowpack have been isolated to storm snow interfaces. Recent strong winds have been from a variety of directions and have been loading leeward and cross loaded features in wind exposed terrain. The mid-December interface is now down 100-150 cm and is generally considered to be stable in this region.
