OK is it a coincidence that this happened during some aboriginal religious ceremony? Crikey, if there is anything to learn from scores of bad B movies, it is do not tempt the old g-ds; crankiness is directly proportional to age among the supernatural. Think about it, all those ancient dudes (and dudettes) they were mean to the core. I guess when you have been around for so long it just gets tiresome to hear and see the same ol' thing.
Towards the end of the video there is the realization that this thing was going to hit us. I yelled turn around, and it soon engulfed and pelted us with ice, snow, and cold cold moisture. Luckily we were dressed well enough - no swimmers - to endure it.
