Observer Comments

We stayed on the lower slopes, checking out the new snow and wind effected areas. Poked around in the trees and meadows just above the Powerline trail and below Blueberry knoll. In one protected meadow, our party of 3 set off a large whumph. The Thanksgiving Crust was just 40 cm below the snow surface in that location. Further up, we saw a small natural slab avalanche and then were able to get additional cracking and small slabs to run on that same small test slope (see pictures).

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

Warm (36 F at the car), partly cloudy, with variable wind. Five to 10 mph for most of our short tour with a few gusts to 20 or 30. Lots of wind up higher and signs of snow transport off of the peaks. No new precip.

Snow surface

Mostly soft snow but wind affected pretty much everywhere. In protected tree areas, the snow was soft but dense. New snow from yesterday seemed to have settled out. Ski penetration was 20 cm, boot penetration was knee deep. No formal tests or pits, but TG crust was 65 cm down based on numerous pole probes.
