Observer Comments

I heard two whumphs and we saw a few shooting cracks throughout the day. Cracks were only in the pockets made by kick turnsm but went were deep (~10-15") where the new snow was deep, we didn't see if these cracks stopped at the top melt freeze crust or a lower layer.

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

New snow was deep in some pockets, up to 15" or so, average was more like 8". New rollerballs running from 2200'+, with lots coming from above treeline. Felt warmer up high, but could have just been getting into the sun.

Snow surface

Warm powder (wet but not saturated) on the surface especially from 2000'+. Wetter on more southern aspects. Breakable crust on the surface around 1600' and below.


No formal tests. New snow seemed well bonded to a (from the start of this storm?) melt freeze crust based on hand pits. Snow felt wet throughout.
