Dense settled powder. Snowpack is very supportable on skis, boards or machines. However - step out of your skis and you sink to the ground.

Comments

Surface snow was warm and dense with old surface hoar flakes lying flat. Not a concern in this location.

Sinking to the ground is the most relevant piece of information. It's just a matter of how much of a load it will take to get avalanches breaking on faceted layers. There are plenty of faceted layers for an avalanche to choose from.

Stability/snowpack test results show that the facets seem to be adjusting quite well to last week's load of new snow. I dont know what load tonight will reactivate them - however, this storm will give us good information. For Saturday, I wouldn't trust this snowpack - Its guilty until provent innocent.
