The father of the 22-year-old hiker who went missing in Yellowstone National Park on a solo trek, found a chilling note that revealed the treacherous conditions he faced before vanishing, according to a report.
Austin King set off on a seven-day backcountry trip in mid-September, with the goal to reach Eagle Peak, the highest mountain in Yellowstone. On September 17, King called his family to let them know he had reached the summit, but that was the last they heard from him, according to the National Park Service.
