https://www.nps.gov/yose/lostandfound.htmHopefully Yosemite has a higher number of honest folks and someone turned in your camera into the lost and found. The pictures are worth more than the camera. Though it's more unlikely that someone would take the camera but leave the memory card with L/F. It would be an expensive "finder's fee" if someone did that, but at least you'd have your photos. I wish you luck getting everything back.
Similar thing happened to someone I know. He misplaced/lost his Garmin 60csx GPS during/after a long hike. More than likely it happened on one of the crowded shuttle buses. But also could have been at the Village Store on one of the benches in front, while enjoying a couple of cold beers. Or maybe even along the Snow Creek trail (not as likely). August 5, 2017 was the date, in the unlikely event someone on this forum turned it in. Again, it's not really the device itself. Rather it's all the waypoints and everything else that was logged. Dates and places. Lots of history lost. He wishes he had placed some type of sticker with personal info on the device, or a simple note card in the carrying case. Strange part is that the carrying case is usually securely clipped onto his waist. Maybe he was pickpocketed on the shuttle? Probably not. Perhaps the clip snapped on the loud, crowded shuttle.
In my friend's situation, he wanted to make sure it was actually lost (looked everywhere in his house) before he reported it only about a week ago. We'll see how long it takes to hear back from the park, with any type of news (good or bad).
