National Park Service Ranger Dies in Crevasse Fall on Mount McKinley

A National Park Service ranger died Thursday afternoon after falling into a crevasse on Mount McKinley, the highest peak in North America, according to officials at Denali National Park and Preserve. The ranger was identified as Robin Pendery, 33, of Enumclaw, Washington, a seasonal mountaineering ranger who joined the Denali staff in 2024.

Pendery fell into a crevasse near the 14,000-foot camp (4,328 meters) at approximately 2 p.m. on June 4 while on a climbing patrol, the National Park Service confirmed in a press release. Rescue personnel responded immediately, but Pendery did not survive.

A Life Dedicated to the Mountains

Pendery was far more than a seasonal ranger. She brought nearly a decade of experience as a mountain guide, ski patroller, and avalanche forecaster in the Pacific Northwest, having begun her career in 2015. She was also a registered nurse who worked in an emergency department in Seattle, having studied nursing at the University of Washington.

According to Alpine Ascents International, where Pendery worked as a guide, her significant ascents included Mount Rainier, Mount Hood, Mount Baker, Mount St. Helens, and Forbidden Peak. She had guided three expeditions on Mount McKinley in recent years. Her certifications included Wilderness First Responder, CPR, AIARE Pro Level II, and AMGA Rock Guide Course training.

Jonathon Spitzer, Director of Operations at Alpine Ascents, described Pendery as a “phenomenal person” who was well loved by fellow guides and climbers, as reported by Alaska’s News Source (KTUU).

Community in Mourning

“We are heartbroken by the loss of a member of our Denali family,” said Superintendent Brooke Merrell in the NPS statement. “Our mountaineering rangers dedicate themselves to serving visitors and helping others in one of the most challenging environments in the world. Today, we mourn the loss of a valued colleague, friend and teammate. Our thoughts are with Robin’s family and loved ones.”

Pendery’s family was en route to Alaska as of Friday, according to KTUU. The NPS said it is focused on supporting the employee’s family, friends, and colleagues during this difficult time.

A Deadly Season on Denali

Pendery’s death marks the fifth fatality on Mount McKinley during the 2026 climbing season. Just one week earlier, on May 27, three Latvian climbers died after falling near Denali Pass at approximately 17,200 feet. A fourth climber was rescued via helicopter long-line. They were part of a seven-person team traversing a route known for its exposed sections, where many climbers have died or been injured over the years, the Associated Press reported.

Earlier in the season, another climber died from a medical emergency near the summit. As of late May, there were 516 climbers on the mountain, which typically sees climbing activity from late April through mid-July.

Investigation and Context

The incident remains under investigation, and additional details are not yet available. The mountain, standing at 20,310 feet (6,190 meters), is known by its Indigenous Koyukon Athabascan name Denali, meaning “the high one.” The federal government has alternated between the names Denali and Mount McKinley in recent years, reflecting ongoing political and cultural tensions.

The loss of a ranger in the line of duty is a significant event for the NPS community. Mountaineering rangers at Denali conduct climbing patrols, provide safety education, perform emergency rescues, and maintain routes in one of the world’s most extreme environments.

What to Watch For

The investigation into Pendery’s death may lead to reviews of safety protocols for climbing patrols on the mountain. The broader question of climbing safety on Denali, particularly on exposed sections and near crevasses, is likely to receive renewed attention given the multiple fatalities this season. The NPS has indicated that additional information will be released when it becomes available and appropriate to share.

Pendery’s legacy as a dedicated mountaineer, nurse, and public servant who chose to work in one of the most challenging environments on Earth will be remembered by the climbing community and the National Park Service alike.
