OGDEN -- The teenager who died Saturday night after falling while hiking and climbing in Waterfall Canyon was identified by Weber County Sheriff's Office as Christopher Kirvan, 17, of Roy.
Weber County Sheriff's Sgt. Lane Findlay said Kirvan was climbing the rock face next to the waterfall around 7 p.m. when he reached for a rock that came loose and he fell about 100 feet.
Findlay said Kirvan sustained severe head trauma in the fall.
He said Kirvan's friends administered CPR for about 40 minutes before paramedics arrived.
Rescue workers also tried to save the teen, but he was pronounced dead at the scene at about 9:30 p.m.
Rescue workers said a medical helicopter remained on standby throughout the operation but was not called to the scene.
Findlay said Kirvan and four friends were hiking a well-traveled trail to get to the waterfall about three miles from the trailhead in Ogden.
Findlay said Kirvan and another young man had hiked past the trail's end into more difficult terrain.
Mayomi Ryujin, of Roy, a friend who was hiking with the group, said she and another girl left the others, three boys, early because they needed to get back to meet their ride home.
Ryujin said the three young men were climbing a high rock face without rock-climbing equipment when she and her friend left them.
"They were so high up there," she said recalling the position she'd seen her friends obtain on the mountain. "It's not safe at all."
Ryujin said she and her friend learned that Kirvan had fallen from other hikers as they headed back to the trailhead.
At the trailhead, Ryujin, her mother and friend were busy contacting the families of their male friends to tell them about Kirvan's injuries.
She said the parents of one of the other young men were able to drive Kirvan's parents to the scene, where they and other family members received the news of his death shortly after arriving.
Rescue workers were busy comforting the family as best they could with blankets and physical contact, as family members waited into the night for Kirvan's body to be taken down the mountain and taken away by ambulance.
Ryujin said the group of five who had hiked together to the waterfall were all friends who had attended Roy High School. All of them, except one of the young men who was a year older, graduated last spring.
She said the group frequently participated in such activities together.
Julia Saxton, a recent graduate of Roy High School, said she knew Kirvan because they had some classes together.
"I know there are a lot of distraught Roy High students," she said.
A memorial now is in the planning stages for 7 p.m. Tuesday in the Roy High parking lot, 2150 W. 4800 South, she said.
The event will be both a candle-light vigil and a fundraiser to help the family defray the funeral costs.
