Snow Characteristics Comments

New snow totaled between 10-15" sitting on top of a 6-10"shallow, faceting ground layer. The new snow was fairly inverted with just a couple inches of lighter graupel on top.

The snowpack was very reactive to the weight of a skier with loud, booming collapsing heard/felt/seen throughout the day.

Extensive cracking was also observed.

Fantastic whumpfing today. Weighting any piece of untracked snow led to immediate audible collapses that propagated across the slope.
