More detailed information about the avalanche: 

Arrived to redcone bowl, and one small avalanche had been recently triggered on the north slope from the ridgeline.  Continued stomping along the ridgeline and triggered 3 more avalanches, the last one the largest (see video, crown photo and density profile photo).  Density of snow in crown picture: 15cm 1finger ontop of 15cm fist failing on 1finger old snow surface.  

 

Also ski cut accros the top of a sheltered north facing steep chute on the approach, which resulted in quite a bit of loose dry sloughing from wind deposited snow (see photo).
