Video of Chute du Diable from Mont-Tremblant National Park, Québec, Canada.
Translated from French, Chute du Diable means Devil Falls, or I suppose it could also mean Devil's Fall since the Chute part meaning Fall is singular and not plural. It might sound like splitting hairs, but I personally like the sound of Devil's Fall better as some sort of epic defeat, versus Devil Falls which just sounds like another waterfall with a wicked name.
