Toured up to Red Cone bowl from Tamarck this afternoon to check on new snow amounts and wind deposits.  It looked like things were clearing up mid-afternoon, but snow intensity picked up again for a bit around 3pm, and temperatures began dropping.  ~3-4" of new snow was found in sheltered trees around 10,000'.  Some isolated small areas of wind deposit had as much as 6-8".  At the high point above the north face of red cone at 4:15pm: air temp was a chily -6°C, the clouds parted, the moderate to strong SW winds died dramatically to light levels out of the south, and late afternoon sunshine made for a beautiful ski out.  Stomping on small cornices above the north slope, and ski cuts produced no results, and no cracking or other signs of instability skiing down the wind deposited snow in the bowl (~4-6" new snow).  

Dug a quick pit just below the ridge on the more shallow western slope to check on facets at 10,250', and found: 83cm total snow depth.  

-83-75=new snow, 4 finger minus.

-75-73=thin layer of fist facets

-73-72=thin decomposing melt freeze crust

-72-ground = faceted grains transitioning from 4finger at the top of the layer to pencil at the ground.

-CT1 Q1/2 @ 75cm (top of thin facet layer).  No other failures.   

Despite the lack of signs of instablity on this tour, I would imagine that concerning pockets of newly deposited wind slab could exist in steeper more extreme terrain, below ridges and cross loaded gullies/couloirs.  Winds could be seen blowing snow all around the mammoth area to Bloody Mtn from the Hwy at 2:30pm (see attached video, just capturing a little bit of that).
