This Ski-Powder.com video clearly shows the speed and power of an avalanche. It appears to have been filmed by a climber who calmly filmed the event and panned up and down the chute to show final streams of snow and water. An instant rainbow formed when the snow hit the river.
Another Ski-Powder.com avalanche video. This one of a large avalanche triggered by an explosive charge. In the beginning of the video look for the tiny white helicopter on the very right side of the screen. The crew is planting the charge. Then when you see the shot go off start counting until you hear the sound. Now you know how far away the camera was from the source of the slide.
