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

Light snowfall and very light wind in morning, with winds subsiding to calm in the afternoon. Clouds gradually lifting throughout the day.

Snow surface

6-8" of new snow.


Numerous hand shears indicated that new snow is bonding poorly to underlying facets. That said the new snow was fist hard, and in most areas didn't behave in a slablike manner. Up to roughly 2800' there was a thin layer of moist facets under the new snow.
