The body of a 22-year-old Missoula man was recovered from the north side of Mount Siyeh in Glacier National Park on Sunday night, Sept. 14, at approximately 7 p.m., park officials announced Monday.

Evidence suggests Beau Weiher died after BASE jumping off Mount Siyeh, according to the National Park Service. BASE jumping includes leaping off a fixed object with a parachute.

Park dispatch was notified Saturday at 8 p.m. from Weiher’s family that he was overdue from a solo day hike in the Many Glacier area.

Early Sunday morning park rangers initiated a ground and aerial search. Information from Weiher’s family and friends indicated that Weiher’s intended route was probably a challenging hike in the Piegan Pass and Mount Siyeh areas, and may have included a base jump.

Park rangers found tracks that suggested Weiher might have been in the area below the summit of Mount Siyeh. The area included snowy terrain. At approximately 6 p.m. Sunday, personnel on board the Two Bear Air Helicopter spotted what they believed to be a parachute. Weiher’s body was found at approximately 7 p.m. Sunday night below the summit of Mount Siyeh.

The body was recovered and transported to the Many Glacier area via Two Bear Air. Glacier County Sheriff’s Office confirmed the death and the identity of Weiher.

The initial investigation indicates that Weiher attempted to BASE jump off an area of Mount Siyeh. BASE jumping is prohibited in most National Park Services sites, including Glacier National Park.

Cooperating agencies that assisted the National Park Service with this incident included Two Bear Air, Flathead County Sheriff’s Office, and Glacier County Sheriff’s Office.
