Glacier National Park on Friday released the identity of the Portage, Indiana, man who died Tuesday after falling on Mount Jackson while hiking with his son.

Dann R. Pilibow, 56, and his 27-year-old son were descending the east face of the 10,052-foot-tall mountain when the pair fell. His son was able to self-arrest on a snowfield and survived with minor injuries.

Glacier Park spokesman Tim Rains said Pilibow fell about 80 to 100 feet.

A helicopter search by Two Bear Air Rescue was unable to locate his body until Wednesday. Minuteman Aviation, which operates helicopter tours in the park, worked with a technical rescue team and recovered the body Thursday afternoon.

The son — who has not been identified — was transported via helicopter to West Glacier and then taken by Three Rivers Ambulance to North Valley Hospital. Hospital spokeswoman Catherine Todd said she did not know the extent of the man’s injuries, but said he was discharged Thursday.

The climbing route on Jackson, one of six peaks over 10,000 feet in Glacier, varies from a Class 3 to Class 4, depending on the route and the amount of snow and ice.

The routes are considered arduous with an elevation gain of 4,800 vertical feet, high amounts of loose scree and a significant amount of exposure on narrow ledges with steep drop-offs.

Falls are one of the leading causes of death in Glacier Park.

According to “Death in Glacier National Park” by Randi Minetor, there have been 32 climbing deaths and 21 deaths from falls while hiking in Glacier’s 106-year-old history.
