A dramatic video has surfaced from Whistler, Canada of a skier being knocked off a cliff by a small avalanche.
In the clip, which was filmed from a helmet camera last month, the skier is traversing a steep slope when suddenly the snow beneath him cracks.
The avalanche sends him sliding down and carries him off a 15-19 metre rock with a sheer face.
No-one else was involved in the incident and he escaped without serious injuries.
