I just happened to run across this and thought I'd share information on this film:
I haven't seen it, but the trailer looks good.
Snow Guardians premiered in Bozeman on Dec. 28, 2012. It was shown in a few places around the U.S. in 2013. The film is a documentary that includes a lot of footage from Bridger. Also filmed at Big Sky. They were filming in March 2012 when there was a large in-bounds avalanche during control work. The film is a collaboration where professionals donated their time and talents to the effort. The trailer gives a taste of the stunning photography.
The film is now available on Vimeo On Demand. Can get access for one year for $9.95.
