Curious about exactly what it looks like to be riding on the surface of a fast moving avalanche? This is your chance. Once this avy cracks at 0:36 the visual experience just becomes surreal. You see the original crack, you see the spiderweb fracturing of the snow surface, then the rapid downhill movement, followed by further cracking of the snow as it the avy goes over a small bump, and then the slow process of the snow engulfing the camera.
Scary, huh?
