Glacier National Park staff are scaling back search efforts for missing hiker Jackson Kresier. The 19-year old Michigan man has been missing since he didn’t return from a day hike last Saturday.

Park staff say searchers haven’t found any new clues, and search efforts will be limited until new information surfaces. Yesterday, boot tracks led searchers to a dangerous cliff area, but no sign of Kreiser turned up.

Park staff believe Kreiser is wearing a yellow and gold sweatshirt, with grey pants. He’s about six feet fall with short, black, curly hair and a beard. Anyone with information on where he might be can call park dispatch at 406-888-7800.
