A hiker impaled by a trekking pole on Montana’s highest mountain managed to descend for six and a half hours, covering roughly 10 miles before receiving medical care. David Cifaldi’s escape was not simply an endurance test. It depended on medical judgment, steady friends and the sensible decision not to pull a foreign object out of his body while standing around 12,000 feet above sea level.

Cifaldi, a wound-care nurse, was climbing Granite Peak with Brad Reich and Jesse Ross when he slipped on rocks. After getting back to his feet, he realized one of his poles had pierced his side.

“I just slipped on some rocks,” Cifaldi told KTMF. “It was just kind of a freak thing.”
