Other visitors who witnessed the incident made their way back to the trailhead, where they encountered two park maintenance employees working in the area, who relayed the information to Yellowstone law enforcement rangers.
The victim was moved by rangers to the trailhead to await helicopter transport to a medical facility, but after attempts to revive him failed, he was declared dead at the scene.
Yellowstone rangers who responded reported windy weather conditions in the area at the time, and that the fallen tree had been a standing, dead lodgepole, fire-killed during the park’s 1988 fires.
The victim’s name is being withheld pending notification of family members. The incident remains under investigation by the National Park Service.
