Snowpit Observations
More detailed information about the snowpack: 

Warm air temps with a deep snowpack creating a very uniform and stable snowpack.  Some facets developing just below a thin surface wind crust, not currently a stability problem.  Small, 1-2mm, surface hoar at lower elevations only-below 7200'.  E/NE winds light but just enough to keep things cool at upper elevations.  No roller ball activity observed today.
