LAYTON -- A teenage hiker fell 80 feet and suffered critical injuries Saturday night, Davis County sheriff's deputies said.
The accident happened about 7:30 p.m. at Adams Falls in Adams Canyon east of Layton.
The boy suffered multiple system trauma, including broken bones, Davis County Sheriff's Deputy Kelly Sharp said.
Personnel from the Davis Search and Rescue and the Layton fire department responded on foot.
A LifeFlight helicopter hoisted the teen out of the canyon and took him to Primary Children's Medical Center in Salt Lake City.
Deputies said numerous hikers were on the trail and were able to help the injured boy and summon rescuers.
T.J. Dab was one of the hikers who helped the boy and his friends.
"We ran into this kid who was running down the trail shouting for help," Dab said.
He and several other hikers helped comfort the boy, flagged down the helicopter and hoisted him onto the net.
"He was really beaten up, so he needed as many hands carrying him," he said.
The boy fell while climbing down from the falls and may have been split up from his friends. He was hiking with a group of four.
Sharp said in recent memory there have only been two other incidents of people getting seriously injured at the falls.
