On Sunday, January 9, two boys went exploring in Bear Cave, Westmoreland County, Pennsylvania. They had two flashlights with one spare set of batteries. This semi-maze cave proved too confusing and their lights failed before they could exit. The two had left word with their parents, however, as to their destination, so in due time rescuers were called and the victims were found. They had been underground 17 hours.
