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

Sunny, calm wind, in the single digit temps.

Snow surface

Highly variable. Windblown powder, wind crusts, ice crusts.

Snowpack

Did 2 column tests at the summit of skyscraper - not very representative of the slope. But shows how variable the snow pack is depending on where you are. 1st pit yielded a result after 13 taps, broke under the 8" of wind slab, which stayed as a cohesive layer. 2nd pit yielded no result after 30.

Once we got into the east facing Skyscraper chute, it was settled powder with an ice crust between about 4" of settled powder on either side.
