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

High winds, no precip, warm 32F.

Snow surface

The surface was a mix of scoured rock, scoured old melt-freeze crusts, and more recently deposited wind slab.


No formal tests were performed. Hand sheer tests showed a softish slab with poor bonding to the snow beneath (where there was snow beneath it). Collapsing/whumphing of the wind deposits was expected but not observed.
