More detailed information about the snowpack: 

Afternoon trip up to Twin Lakes to enjoy the new snow.  I figured parking would be the crux of the day but miraculously I found a plowed spot off the road.  

HNS at the road was 4in.  HNS from 8k-9k was 8-10in.  This new low density snow was sitting on top of 6-8in of wet snow from our recent rain event.  In most areas it appeared the new snow had accumulated quickly enough to insulate the previous snow surface and prevent it from properly freezing.  It was consistently supportable with skis but boot pen was around knee height.  Isolated terrain where sustained southerly winds had stripped the new snow had a frozen rain crust, creating slick skinning conditions.   

Localized collapsing was apparent throughout the day (cracks less than 1ft from skis) but I did not experience any larger collapses.  Hand pits showed the new snow bonding well to the previous surface.   Ski cuts in newly formed wind drifts showed only minimal reactivity (see photo)

No avalanche activity or any other glaring red flags in the terrain covered today, however it was all mostly sheltered and low/moderate angle.  Great skiing in cold smoke with the best turns on slopes >30 degrees.  Bottom feeding was increasingly apparent as slope angles increased.
