More detailed information about the avalanche: 

This was up right by the ridge. I threw a 360 and the landing triggered a slab avy from the wind loaded snow. It was my 3rd lap and I had already skied once on this same slope that slid. The second video was cut right as it was happening but shows it starting. I tried to ski to the side, but the crack went a few hundred feet further than where I was at, and there were trees around me. I pointed my skis straight down and tried to out ski it. As soon as the slide started moving underneath me it knocked me over. Luckily there was a little knoll to stop the slide and I was only buried to my knees.
