Route & General Observations

Snow line at 3500′. Semi supportable 2cm rain crust from 3500′ to 4250′. High density pow above 4250+ with minimal wind effect. Generally good skiing conditions above 4300′, but 4000′ cloud level and flat light created very challenging skiing and skinning conditions.

Red Flags
Red flags are simple visual clues that are a sign of potential avalanche danger. Please record any sign of red flags below.
Observer Comments

SW aspect approach gully had old wet loose debris throughout its length and apron. No signs of current instability.

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

Overcast with cloud ceiling at 4200'. Clouds rolling through created very poor visibility on the glacier. Lightly snow started @ 2 pm. Moderate winds from SSW

Snow surface

Snow line at 3500'. Semi supportable 2cm rain crust from 3500' to 4250'(top of approach gully marked immediate change from rain crust to settled/wind packed pow). Surface of rain crust was somewhat rough from wind scouring and decomposition. High density settled pow above 4250. Slight cracking around skis of upper 2" windslab. Extremely poor visibility prevented seeing a more holistic view of surface conditions in the area.

Snowpack

No formal pits dug. Pole probes above 4200' showed roughly 1 meter of snow on glacier. Hand pits generally revealed ~16" of settled pow (p hard) above a softer (1F?) 1" layer of preserved stellar dendrite. Hand pits failed at this interface with moderate force.
