Date of Observation: 12/02/2016
Name: Zach Guy and Ben Pritchett
Aspect: South East
Elevation: Above treeline
Avalanches: Investigated 2 crowns of recent remotely triggered avalanches. See photos. Extended column tests produced hard to additional loading propagating results on 1mm facets near the ground, with spotty crust distribution above the weak layers. Slabs ranged from 40 cm to 100 cm 4F to P hardness, depending on wind effect.
Weather: Overcast skies. Light SE winds. Light snowfall.
Snowpack: Snow depths increased from 25-30 cm below treeline, up to 130 cm in the heaviest wind drifted features above treeline. Near and below treeline, the snow was generally too incohesive and shallow for avalanche concerns; the potential exception would be heavily windloaded features. The base of the snowpack is comprised of 1mm facets, and there was some very small and localized collapsing on this layer near treeline. Above treeline, this same basal weak layer exists, with more of a cohesive slab above, ranging from ~40 cm to ~100 cm
