Quick Observation
Cold temps, but light winds in Cascadilla Drainage.
We saw obvious signs of wind effect on all aspects above 6500 feet.
East aspect had more settled fresh snow making it feel "thick" while skiing. No solar effect on this aspect (or south aspect) despite being in the sun most of the day.
Winds were far more mild than forecasted and appeared to be from the SW. We experienced minor cracking while skinning in steeper terrain and on ridges above 5800'.
We witnessed one fresh (overnight?) wind slab release on a steep north facing slope below the ridge, most likely triggered by a cornice. Many more fresh cornices were developed over the past week on ridgelines as low as 6000'.
We skied north and west facing slopes above 36 degrees with only mild sluffing; however, in more exposed terrain it likely would have been possible to trigger a wind slab/pocket.
The potential for storm slabs seems to have settled out in the past 24 hours. The skiing was stellar on protected slopes where the wind had not effected it!
