More detailed information about the snowpack: 

Snowpack depth is greatly increased after this last snow/rain event especially above 8000'.  At 9500' on the East Ridge of Tamarack Peak HS=190cm, there was a 2cm rain crust from the Sunday storm with 45cm of new snow on top.  Similiar conditions existed at 9700' on the shoulder of Tamarack Peak, HS =180-200cm, rain layer was barely detectable with 45-50cm of new snow on top.  Surface snow conditions were new unconsolidated snow that had some sort of wind effect depending on how exposed the terrain was.

Video:  ECTN at hasty pit on East Ridge of Tamarack Peak, 9500', North aspect, 32 degree slope, just East of Prolitariate Bowl.  HS=190cm at pit location.  Basal facets could be felt with probe but seemed more consolidated than pre storm.

Photo#1and #2:  2 separate natural avalanches off of the East Ridge of Tamarack Peak.  9400', North aspect, 35-40 degree slope, D2, R2.  Both of these thought to have occured during the high rain event early Sunday morning, debris mostly covered up by new snow.

Photo #3:  Large cornices continuing to build out today with the moderate SW winds and were breaking off easy with the weight of a skier.
