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.

Bennett says it took rescuers about 20 minutes to reach the boy, and he was reported responsive at the hospital.
The boy's name and current condition have not been released.
Bennett is warning hikers to stay away from the cliffs which he says are extremely slippery and lack barriers.
