Problem #1 Comments
Alternating between S-2 and S-5 for most of the morning, but with minimal wind transport and low density. New snow was running long and fast on wind and sun affected slopes; sensitive but non-hazardous as of now.

Problem #2 Comments
As in most areas of the Wasatch, the White Pine area has recently been prone to wind-loading in varying directions. This is evident in ridgetop cornice formation, contradicted by signs of wind transport back to typically windward (SW) aspects. No apparent active loading; previous loading is the concern at mid/high-elevation terrain.

Comments
Relatively good cohesion in the main body of the snowpack. As we move into an active weather pattern, our main concern for north-facing terrain could be the near surface facets beneath new snow, especially if this new snow forms a cohesive, wind-effected layer.
