Snowpit Observations
More detailed information about the snowpack: 

Evidence of rain to 11000' on 1/4/2018. Trace amount of new snow capped by up to 2cm rain crust. Near surface facets developing on top of raincrust widespread. Widespread surface hoar observed on snow surface around 10500' on exposed W facing slope. Informal hand pits revealed easy and clean failures of the thin rain crust on precipitation particles beneath which were well preserved. Not much of a concern now, but possibly when buried by subsequent storms. Rain crust was breakable with skier weight.
