Fire officials say a 17-year-old boy fell 30 feet off a cliff while hiking in a remote area of Massachusetts on New Year's Day.
Princeton Fire Chief John Bennett says the teen was hiking in the town around 10:30 a.m. when he fell.
Bennett says the boy had grabbed onto a tree branch on top of the cliff and the branch broke, causing the teen to fall and land on his back 30 feet (9 meters) below.
