Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Light snowfall -1cm/hr. High humidity, mostly calm winds, but occasional gusts swirled through.

Snow surface

2" of dry new snow (Fist hardness) on top of, 4-10" partially settled new snow (4F hardness).


Highly reactive snow found on N aspects, where the "new" snow sits on top of near surface facets. ECTP12, CT1 Q1 (Sudden Collapse), CTC Q1 (Sudden Collapse).
On aspects without, near surface facets, stability, seemed fair to good. There were some density inversion in the new snow, and in some locations I observed a shear plane within the new snow.
