Diane Bunker, 73, Dies in Tragic Fall on Glacier National Park’s Highline Trail

The majestic, rugged beauty of Glacier National Park was the setting for a profound tragedy this week that claimed the life of a vibrant Iowa woman, reminding all of the fragile line between adventure and peril. Diane Bunker, a 73-year-old from Muscatine, Iowa, died on Wednesday after a catastrophic 450-foot fall from the famed Highline Trail.

The incident occurred in a steep and exposed section of the trail between Big Bend and the Triple Arches. Bunker was hiking with a large group of companions when, in a heart-stopping moment, she tragically stumbled and fell over the edge, vanishing from sight. The group immediately alerted park officials, who received the distress call at approximately 11 a.m.


In a swift response, the park’s renowned helicopter rescue service, Two Bear Air, was dispatched to the remote and treacherous location. Crews located Bunker’s body far below the trail and performed a difficult recovery operation. The Park Service confirmed she succumbed to traumatic injuries from the fall.

To facilitate the recovery and ensure the safety of the crew, a segment of the iconic Going-to-the-Sun Road was temporarily closed for about an hour, a solemn pause in the park’s bustling summer activity. The incident is a stark reminder of the inherent dangers that accompany the breathtaking vistas of one of America’s most wild and beautiful landscapes.

Diane Bunker’s passing is mourned not just by her hiking group, but by a community that remembers a woman whose spirit for exploration and love for the great outdoors defined her life. Her story is one of passion and adventure, tragically cut short on a path she loved.
