Hmmm, with a gopro I could see it going either way. If I came upon one at the ski area, I would almost certainly drop it off at lost and found.
For those of you who lose them in deep powder. Schedule a return trip in the summer to go hike around and look for it. We've had a few guys around here lose their gopros in powder. The went up to the area in the summer and found them. Managed to pull the footage off the of the camera and more importantly the camera still worked fine. So it's worth your time to go look for it.
