Here's the deal: A man named David Nieland was recently hiking in the mountains along the Blue Ridge Parkway in North Carolina when he spotted a memory card near a stream. He picked it up, took it home, and accessed the photos on the card, a few of which offered enough visual clues to help him track down the family that had taken the photos.
The family was particularly appreciative to have the photographs because they included a few shots of a family member who had since died of cancer. This angle made the story irresistible for the Today show, which recently produced an extremely hokey (but nonetheless informative) segment about the memory card:
As noted toward the end of the Today segment, one of the most interesting aspects of the story is that Nieland -- the guy who found the memory card -- was recently reconnected with a lost object from his own past. His grandfather's high school diploma had somehow ended up in a garbage truck, where it was found and ultimately returned to him.
(Special thanks to Jennifer Hayden for pointing me toward this one.)
