Park Ranger Dies in Horror Fall While Patrolling America’s Tallest Mountain

A National Park ranger has died in a tragic climbing accident after falling into a crevasse while patrolling the highest peak in North America.

Robin Pendery, 33, was working on a climbing patrol on Mount McKinley in Alaska on Thursday, June 4, when the deadly fall happened near the mountain’s 14,000-foot camp, according to the National Park Service.

The accident unfolded around 2 p.m. local time in one of the most dangerous and unforgiving mountaineering environments in the world. Other National Park Service personnel rushed to help immediately, but Pendery could not be saved.

The National Park Service said Pendery was a seasonal mountaineering ranger who had been helping protect climbers and assist with rescue operations on the massive Alaska peak.

“We are heartbroken by the loss of a member of our Denali family,” Denali National Park and Preserve Superintendent Brooke Merrell said in a statement.

“Our mountaineering rangers dedicate themselves to serving visitors and helping others in one of the most challenging environments in the world,” Merrell continued. “Today, we mourn the loss of a valued colleague, friend and teammate. Our thoughts are with Robin’s family and loved ones.”

Pendery, who was from Enumclaw, Washington, joined the Mount McKinley mountaineering staff in 2024. Her job placed her in the middle of a brutal landscape where altitude, ice, weather and hidden crevasses can turn deadly in an instant.

Mount McKinley, formerly known as Denali, rises 20,310 feet above the Alaska Range. It is the tallest mountain in North America and one of the most feared climbs on the continent.

One of the mountain’s biggest dangers is its glacier terrain. Crevasses, which are deep cracks in glacier ice, can be hidden beneath snow bridges and difficult to spot, even for experienced climbers.

Pendery was no beginner. According to her profile with Alpine Ascents International, she had more than a decade of mountain experience and had worked as a guide, avalanche forecaster and ski patrol member in the Pacific Northwest since 2015.

She was also a full-time emergency room nurse, but her passion for the mountains kept pulling her back to the ice, snow and high-altitude world she loved. She had climbed major peaks including Mount Rainier, Mount Hood and Mount Baker.

Her death has devastated the tight-knit climbing and rescue community.

“We are devastated to report the loss of one of our climbing rangers, Robin Pendery,” ranger Chrissie Oken said, according to Denali Rescue Volunteers.

The group also shared its heartbreak online, saying the community was sending love to Pendery’s family, friends and fellow rangers.

A close friend, Bailey Disher, told The New York Times that she last spoke with Pendery in April, when the ranger called to wish her a happy birthday. During that conversation, they talked about the dangers that came with Pendery’s work.

“She knew that there were a lot of risks associated with this level of mountaineering in this level of guiding,” Disher said.

For those who knew Pendery, that awareness makes the loss even more painful. She understood the danger, but she also understood the calling.

She spent her life helping people survive in places where one wrong step could be fatal.

Now, the climbing world is mourning a ranger, nurse, guide and friend who died doing the dangerous work she loved.

The National Park Service said an investigation into the deadly fall is ongoing.
