This is a drone video from Vancouver, British Columbia, where Youtuber mactac was trying to capture some scenic footage of a mountain range when he inadvertently captured an avalanche flowing down the mountain like water. Talk about being in the right place at the right time! Or, if you were a person on that mountain, the wrong place at the wrong time.

Keep going for the video, all the avalanche footage is at the beginning though so feel free to stop after the snow stops flowing.
