WEST GLACIER, Mont. (AP) — A 22-year-old Montana man has died, possibly after attempting an illegal BASE jump in Glacier National Park.

The National Park Service was notified at Saturday night that Beau Weiher, of Missoula, was overdue from a solo day hike in the Many Glacier Area.

Family and friends say he likely planned a hike in the Piegan (PEE’-gun) Pass and Mount Siyeh (sy-EE’) areas. They say he might have planned a BASE jump, an activity that involves leaping from a ledge or other fixed object with a parachute.

Searchers began looking for Weiher on Sunday morning and eventually found tracks in the snow that indicated he might have been in an area below the summit of Mount Siyeh.

At about 6 p.m. searchers in a helicopter spotted what they believed to be a parachute. Weiher’s body was found at the base of Mount Siyeh on Sunday night.
