More detailed information about the avalanche: 

R4-D3.5 (large relative to path, could damage a railway car, destroy a car, a woodframe house).  Looks to have gone naturally during heavy rain event last night/yesterday.  Wet slab.  2.5ft+ crown, wrapping around upper parts of both entire bowls.  Northerly facing bowls, starting zones in the low 30s for the most part.  Failed and ran ontop of upper October rain crust (~15cm above ground).  Underneigth this rain crust was mix of frozen basal ice and 2-2.5mm facets.  Entire snowpack to ground, save for top few inches of new dry snow, was quite moist.  12'+ debris piles in bottom portion of bowls.  Some small trees were taken out, along with some 10" diameter dead ones.  Of note, avalanches ran in forested areas adjacent to open bowls in the lower 1/2.  

*Skiing and riding has now gone to crap in the bowls, between firm shallow bedsurface with icy spots to frozen chunder avy debris (hard to walk thru, let alone navigate a ski or board).
