"While grooming the xc trails in Beaver Creek drainage last night, I observed extensive cracking and collapsing in the 12"+ of new snow. Essentially every slope above the trail would fail as I approached them, some breaking up to 30' away. I know it's not a good sign but was cool to watch.
7,5k'-7,9k' mostly North facing aspect.

Yesterday's addition here was right side up with the initial snow coming in very wet and heavy, while ending in a light fluffy topping which is now getting blown around. Additional trace overnight and currently snowing again at 8am. "

I skinned up the south edge of the apron below the midways today. 12 inches plus or minus, the wind moved it a little. Hard crust underneath up to 3” thick. 3 good whoomphs on the up track and another skier that broke trail above me to the bottom of the first midway said he had a good settlement while he was stomping out a spot. I didn’t see any cracks or any movement but it made me step back
From obs: "Dug into the hillside right before going up the creek. Snow pack was 75 cm deep consisting of three layers. Bottom 35cm is obviously faceted, grain size is around 2mm. Very thin ice crust at around 35cm. Upper 35 cm of snow is brand new snow from this current storm, precipitation particles, low density, with minor wind effect. Performed a quick Compression Test and the ice crust layer failed on the second tap." Photo: S. Gralla

"We skied in Republic Creek and Hayden Creek today.
No avalanche activity observed, but we had very widespread collapsing (about 20 large thunderous ones), on all aspects, primarily in the upper elevations.
Snowpit attached from a west aspect at 9700'. HS: 90. ECTP3 @ 54."
