Against a montage of cascading snow hurtling down from jagged mountains tops, we are reminded that avalanches are among the most lethal weapons in nature's arsenal. Avalanches of glowing red lava and hot ash erupt from volcanoes, swirling with noxious fumes that poison the atmosphere. Avalanches of rock rush like water, destroying everything in their path. With the use of stunning footage and harrowing personal tales, this DVD reveals the mechanisms by which these forces of nature wreak havoc.
