According to a park release, the hiker who was able to self-arrest on a snowfield was unable to find his companion. He then hiked back to the Gunsight Campground and reported the accident to park dispatch shortly after 11 p.m. Tuesday.

He was later transported via helicopter to West Glacier, and then transported via Three Rivers Ambulance to North Valley Hospital.

Park rangers worked with Two Bear Air and Minutemen Aviation to locate the body of the fallen individual on Wednesday. A technical rescue team worked with Minutemen Aviation to recover the individual on Thursday. Officials did not identify the individuals involved.

 Jackson Peak is one of the tallest peaks in Glacier National Park at 10,052 feet. The climbing route varies from a Class 3 to Class 4 depending on the route and the amount of snow and ice. The climbing routes are considered arduous, with an approximate elevation gain of 4,800 vertical feet, high amounts of loose scree, a significant amount of exposure on narrow ledges with steep drop offs.
