High thin clouds moving in and out through the day. Wind speeds didn't seem to decrease throughout the day, but the amount of blowing snow did.

Snowpack

The PSa problem felt more stubborn in this area. An example was finding a suspect snowpack structure at 11,200ft on an east-facing slope. Crossing the slope with four people and jumping didn't produce any obvious results. Later, I snowmobiled on the slope and was able to get shooting cracks across the slope. The snowpack structure there was around 100cm with a 1F hard mid-pack slab over 4F- facets that were 2 to 2.5mm in size. 

The snowpack structure in the area was highly variable due to previous extreme wind events. Those changes were felt while probing across the terrain. Some areas had been eroded, leaving behind a shallow and weak snowpack, now hiding under the recent snow. While other areas had old hard slabs under the recent new snow. 

Snow surfaces on the easterly- and westerly-facing terrain mostly consisted of decomposing and wind-packed rounds. Some exposed areas had more notable wind-affected snow surfaces. See photos. 

Avalanche

Observed avalanches were all previously reported.
