Tree well inversion rescue video

That's a remarkable statement. What does "mechanized ski industry mean? Does it mean chairlifts only, or also include cat skiing and helicopters?

Sorry I wasn't more specific. I was referring to guided skiing using helicopters and snowcats. This was a comment made by a very credible source on a guides course early this winter. Sorry I don't have the link to the information.

Did you notice the size of the tree?  It was not a majestic hemlock as might be imagined, but a pathetically small (almost) seedling .  One should ask themselves "How many times have I skied by a tree of that size?".  Maybe after seeing the video we all will begin noticing such traps and appreciate the danger. 

That is the size of tree that presents the biggest danger. Larger trees most often have branches too far off the ground to create a tree well that will trap you.
