Snow Characteristics Comments

Snow had settled out from yesterdays almost to deep to ski to around 12 inches in upper Cardiff and Ivory Flakes. Cold and settlement had stiffened it up a little but still quality low density skiing.

Comments

Lots a stability testers in Cardiff today, most of the big steep lines got hammered by flocks of skiers. Sluffing in the steeper terrain was not as extensive as yesterday, thinking the cold, settlement and the north wind from yesterday, stiffened the new snow up a bit and reduced the sluffing. No real sighs of instability in the terrain covered today, dug a pit at about 10,000ft NE facing Ivory Flakes snow pack looks to be in fairly good shape, about twice as deep as the PC Ridgeline, at about 5ft and could not get a clean shear anywhere, even with the boot stomp on the shovel, could still identify the layering but the facets under the crust were non reactive as was the light density snow under the latest slab from last weeks warm wet storm. The depth of the snow pack in Cardiff has played a large part in healing the weak layers with compression and bridging. Did note some new snow activity that probably happened during high PI rates on the 25 but most of it was predictable and minor. Photos, New snow instabilities from the storm in the rock slabs and Hansens, snow pit with the layering showing but no clean shears.

The hazard was definitely in the moderate category in Cardiff today, that being said not so sure about the shallower weaker snow pack on the PC Ridge and other terrain with a shallow rocky snow pack and more loose facets buried in the pack. Hazard seems directly connected to the area and depth of snow pack right now.
