Problem #1 Comments

I had "Wind Slabs" in my forecast today as the primary concern with a CONSIDERABLE danger rating for the higher north through east facing steep wind loaded slopes.  After poking around today I would rate the danger as LOW to MODERATE.  The recent wind drifted snow seems to be plastered into place.  I hit tons of high elevation north through east facing steep test slopes with my machine today and had no results whatsoever.

Comments

I haven't dug around in the 10000' range for a while now and I was quite pleased with what I found today.  The new snow is stable and the older snow from Thanksgiving is looking quite good.  I do not see any significant weak layers anywhere in the snowpack at this time.

There was much less avalanche activity from during the storm than I would have anticipated.  Actually, I saw no significant avalanches from the storm at all.  There was widespread cornice falls but they did not trigger any serious avalanches once they hit the slopes below.
