It all began when Reddit user ashinn found a beat up GoPro camera that had washed ashore in Huntington Beach, Calif. The camera was so rusted and in such poor condition, he had to tear it apart in order to retrieve the SD card, which stores the camera’s files.
Luckily, the card was still readable, and although there were only 16 files on it, ashinn uploaded them to Dropbox, and posted to the subreddit r/WhatsInThisThing, with the title “I found a GoPro washed up on the beach yesterday. Here are the files. How did it get there?”
