Authorities said Chris Scherzinger was on the weekend trip with his father, Jim Scherzinger, in the Mark O. Hatfield Wilderness about 40 miles east of Portland.
The incident took place along the Eagle Creek Trail, a popular hiking trail in the Columbia River Gorge.
The Scherzingers were with other adults and Scouts when Chris Scherzinger reportedly was on some logs when he fell and struck the left side of his head.
Jim Scherzinger said Sunday that he found his son unconscious and bleeding from a deep cut near his ear after friends told the adults leading the hike about the accident.
While adults tried to resuscitate the boy, others reached a doctor who happened to be on the trail. But all efforts to revive the boy failed.
It took over four hours for personnel to bring Chris's body back down over seven miles of the Eagle Creek trail.
Because of the dense woods, remote location and steep terrain, cell phones and even some two-way radios will not work along the trail.
In an interview, Jim Scherzinger said that Chris was "the nicest, most self-aware kid, he was nice to everybody."
"There are a lot of Christophers in the world, and they're sweet young, innocent kids."
Scherzinger said parents should "hold them close."
