 Rescue crews say the 16-year-old was digging a six to eight foot hole in the sand when it collapsed, trapping her neck deep. Rescuers dug for about 15 minutes. Lifeguards, park rangers and firefighters eventually helping lift her out of the sand. As they carried her off the beach, she flashed a peace sign. Safety experts are reminding all beachgoers, don't dig yourself into a hole much past your knees and be sure to fill holes back when you're done.
