I almost lost myself to a tree well. I was relatively new to snowboarding but was a good skier, and figured that I could hit some tree powder no problem. I lost my balance and ended up head down on my back.
It was pretty scary - the more I moved the more I sunk and my energy was almost down to nothing. Eventually I decided to release my bindings which took more energy, while I continued to wonder if this was the best move. Thankfully once I did this I was able to use my board (a 160 cm Airwalk!) as a plank to shuffle me out a bit, grabbed onto a branch and then just sat there for twenty minutes or so
