Any other comments about the observation or links to outside pages that have more info on the observation: 

When we started at Tamarak at 9am, the sky was obscured. It was very windy and snowing quite  hard. At 10:30 snowing stopped and winds calmed a bit. Sky cover was broken at that time. 

I jumped on many small leeward rollovers . Did not get any results. No cracking.

Skied N-facing bowl and trees down to Hoeseshoe lake and did not see any cracking or any sensitive  wind slab build up on my way down. The headwall off the west summit of Red Cone was definitely receiving steady wind loading but I did not ski into it to check sensitivity. 

Handshear at 9300 ft : moderate force , broke at 40 cm on old -new snow interface.

Handshear at 9100 ft : easy force, broke at 25 cm on old- new  snow interface.

Weather cleared. Winds were moderate at ridge top level only and after 12:30 it was low to calm below ridge top level.
