It's kind of wired felling that watching this documentary when I am working for this resort. And the day I watched this is also the day they close the both resort due to high risk of avalanche. So I stay at home and review this said history. It's not as said as I thought, but it remind me should respect our mother nature more next time when I go to Alpine. Ski or working... The whole documantary has many many interview with the person who experience this accident and many valuable materials. It really helps me understand more about avalanche control and many other knowledge about snow and mountains.
