Just got off the Lift. Boot packing uphill 100 ft from the Patrol shack. A pocket of windrifted snow let loose above me . I looked up when I heard by buddies behind me calling out to watch out. I was knocked off my feet by an initial slab, then a second larger slab dragged me down the hill about 20 ft. My snowboard was ripped out of my and swallowed by the mountain. Bummer. No injuries. Happy to be unscathed. Keep your heads up out there!
