See Paul Fall And Lose His Phone While Skiing
I don't have the proof that this was the tumble where my phone came out, but it's only one of two head over heels incidences that happened that day, so the chances that my phone is somewhere in the snow right there are probably pretty good.
What a great fall it was. I saw the rise created by the snow piling on the brush, and went for it, hoping there would be a nice landing on the other side. The landing was nice...nice and flat. My skis stayed put and I popped forward and hit the snow face first. I assume that's where my phone came out. As you can see, the camera on my head was then pointed down, and I got up and skied away, oblivious that my phone was no longer with me.
Oh well, I guess it's time to go shopping!
