Professional snow boarder Meesh Hytner was boarding in the back country near Montezuma, Arizona when a class 3 avalanche literally engulfed her. She only had a few moments to react, and the pro thankfully deployed her BCA Float 30 avalanche airbag in time to help keep her above the snow. The chilling video is featured on Gizmodo, , YouTubeTrends, and GrindTV.
