Spanish climber emerges from 500-day cave isolation

Spanish mountain climber Beatriz Flamini emerged from a cave in southern Spain after spending 500 days isolated from the outside world, setting a possible new world record. Her pursuit was part of a project called Timecave that was designed to study how someone would fare going solo underground for so long. Flamini used two cameras to document her experiences and placed the recordings at an exchange point in the cave. Her teammates dropped off food and other necessities at the retrieval site and picked up whatever she left there.
