More detailed information about the snowpack: 

Skiing today in the Red Cone area today was quite variable. Surface conditions ranged from supportable wind board to large sastrugi to breakable “trapdoor” snow with ski pen around 40 cm.  I didn’t note any recent avalanches or experience and wumphing, however I did note some shooting cracks on steep wind loaded features. I noticed signs of significant settlement and some surface warming. I was unable to find anywhere that had not been affected by the wind in one way or the other, even in the most sheltered areas.

I was able to dig pits in two locations today. One on a wind loaded ENE slope around 10000’ and another on a loaded NW aspect around 9000’.  Both pits showed similar structure and similar test results were found in both locations.  In both locations I found ~20 cm wind slabs that were reactive to moderate force as well as weakness at the interface with the old snow surface. While the sensitive wind slabs are concerning, I was more interested in the lower weak layer.  Test results showed this layer to be more stubborn but it will be interesting to see how it reacts as the wind slabs settle out and the surface snow consolidates.
