More detailed information about the snowpack: 

On 2/11 our route took us from the People's Gate to Voodoo bowl where we turned around after getting stuck repeatedly.  Moderate to strong winds were moving snow available for transport above treeline and depositing on lee slopes.  Light winds with minimal snow transport observed below treeline.  

On 2/12 strong to extreme winds were observed in exposed alpine terrain throughout the day with the majority of slopes above treeline being scoured of any snow available for transport.  Below treeeline moderate, gusty winds were loading lee slopes with loose snow forming wind slabs and "upside down" surface conditions in terrain with any exposure.  Ski cuts and similar attempts at provocation of newly formed wind slabs below treeline produced no cracking or signs of reactivity.   Settlement of our latest storm cycle was apparent with some of the largest settlement cones I've ever seen (2-3ft, approx ski pen: 15cm).

There's scattered evidence of a midstorm avalanche cycle from the Sat/Sun storm.  Partially buried crowns in the D2-D3 range were observed on various steep, convex terrain features on N/NE aspects.
