Austin King, a 22-year-old concession worker at Yellowstone, was last heard from on Sept. 17, when officials say he called friends and family from the summit of Eagle Peak.
ing vanished during a 7-day backcountry trip. A boat dropped King off on Sept. 14 at Terrace Point, along the southeast arm of the lake, the National Park Service said. Two days later, he spoke to a park ranger at Howell Creek cabin in the nearby backcountry, which was not on his intended route. At the time, King was planning to spend the night at a campsite in the area before climbing Eagle Peak on Tuesday.
When King last made contact with anyone, he had reached the top of Eagle Peak. He described fog, rain, sleet, hail and windy conditions while on the summit, according to the park service.
Search operations began when King failed to show up for his boat pickup near the lake's southeast arm last Friday.
