Nice light breeze from SW. very warm out of the wind. Colder at lower elevations.

Snowpack

Snowpack is about 7 feet deep right side up and strong and stable. Failures in extended column test initiated on density changes as well as 85cm down on 1/3 rain crust yet non of the failures propagated. I even did a deep tap test on the 1/3 crust and it withstood 22 taps before breaking. We couldn’t notice any facets under the crust, and the crust is bonded to the snow above it well.
