The new Disney movie, Frozen, used a very sophisticated computer modelof snow behavior. Director of the Forest Service National Avalanche Center, Karl Birkeland visited the Disney studio early in the project to talk to the team about snow and avalanche behavior. He was accompanied by snow researchers, Jeff Dozier and Ken Libbrecht. He said they had a very talented and creative team working on this.

Here is a very cool video of how they did it with lots of examples. If you're not a modeling or algorithm geek, be patient with the first minute of this video. Now, if we could just get these same folks to build a realisticmodel avalanche release and flow.
