One time I hiked Main Chute at Alta from Snowbird. I had a regular HD camera rigged up for a POV. I lost it somewhere in the chute. I skied back to Snowbird and got on the tram. I hiked back to the top of Baldy and skied Main Chute again, skimming it foot by foot for my camera. I could not find it. After skiing the rest of the day at Snowbird I drove to Alta. I went to their lost and found and someone had turned in my camera. I was very fortunate. I hope you are just as fortunate.
Me finding my camera was a good reminder that if I ever find something on the slopes, the proper thing is to turn it in to lost and found. We all lose stuff sometimes, don't be a douche if you find something that doesn't belong to you, turn it in to a lost and found.
