A missing 19-year-old hiker from Michigan was rescued in Glacier National Park Monday night after a helicopter team picked up his heat signature.

Matthew Read initially went missing Friday after slipping into a drainage on the eastern side of the park’s Huckleberry Mountain. Falling into deep snow, Mr. Read lost his phone, water bottle and shoes.

After determining that he couldn’t get back up to his trail, Mr. Read decided to soldier on down the drainage, the National Park Service said.

Mr. Read was reported missing Sunday after his family back in Michigan reported him overdue. Rangers found his vehicle at a lookout, and the search began.

The investigation continued for over a day until slide marks and footprints led rescuers to the drainage. Mr. Read’s heat signature was picked up by the privately funded helicopter rescue group Two Bear Air, and he was rescued at 11 p.m. Monday.

Given Mr. Read’s loss of his shoes and the dearth of supplies, rescuers say he had, despite his slide, fairly good fortune.

“He had a backpack and a little windbreaker, but shorts and stuff. He’s pretty lucky,” Two Bear Air pilot Rob Cherot told the Missoulian newspaper.

The Huckleberry Lookout Trail that Mr. Read had first been hiking on reopened Tuesday morning, having been closed for the duration of the search.
