David Cifaldi, 32, trekked about 10 miles and descended nearly 5,000 feet from Granite Peak with a 44-inch steel-tipped trekking pole still lodged beneath his left arm and out his back.
After slipping near the Froze-to-Death Plateau, the Billings wound-care nurse examined himself, concluded the pole had missed his chest cavity and vital organs, and told rescuers he would hike out.
A six-hour self-rescue followed across boulders, snowfields and backcountry terrain while his two friends supported him and Stillwater County Search and Rescue monitored without intervening.
At the trailhead, the group drove to a clinic before Cifaldi was transferred to St. Vincent Regional Hospital, where doctors removed the pole, treated him and released him; he returned to work within days.
Cifaldi said he would likely make the same choice again, adding that helicopter cost, two experienced companions and a satellite Garmin inReach all factored into declining evacuation.
