The Ranger Who Died on Denali Was Also an ER Nurse and Avalanche Expert — Her Community Is Devastated

Robin Pendery, a 33-year-old seasonal mountaineering ranger with Denali National Park and Preserve, died on June 5, 2026, after falling into a crevasse near the 14,000-foot camp on Mount McKinley in Alaska. She was on a climbing patrol at the time of the fall, which occurred around 2 p.m. National Park Service personnel launched an immediate rescue effort. Pendery did not survive.

The National Park Service confirmed her identity in an official statement published June 5, 2026. The exact circumstances of the fall remain under investigation.

Pendery had been part of the Denali mountaineering staff since 2024, focused on climber safety, emergency response, and high-altitude operations. But her relationship with the mountain long predated her government badge.

A guide for Seattle-based Alpine Ascents International since 2015, she had led expeditions on Mount Rainier, Mount Baker, and Mount McKinley itself. She also worked as a registered nurse in emergency medicine in Seattle, an avalanche forecaster for the Northwest Avalanche Center, and a member of Crystal Mountain’s snow safety program. Pendery spent her professional life preparing for and responding to emergencies in terrain that routinely kills experienced climbers.

Jonathan Spitzer, director of operations at Alpine Ascents, described her to The News Tribune as “next-level great and incredibly smart,” adding that she was the only person he knew “who went to nursing school and thought it was easy.” He had been texting with her the day before her death, while she was on the mountain, asking about his family’s new puppy.

Gordon Janow, director of programs at Alpine Ascents, called her “the consummate professional, compassionate, thorough, with an infectious love for the mountains.”

“Heartbroken by the Loss”

Denali Superintendent Brooke Merrell addressed Pendery’s death in an official statement.

“We are heartbroken by the loss of a member of our Denali family,” Merrell said. “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 had confirmed to Alaska’s News Source that they were en route to Alaska following news of her death. The NPS stated that additional details would be released when it becomes “available and appropriate to share.”

A Deadly Season on Mount McKinley

Pendery’s death was the fourth on Mount McKinley in under two weeks during the 2026 climbing season. Just days before, three members of a Latvian mountaineering expedition — Inese Puceka, Vija Olte, and Renars Kunigs-Salaks — died after falling near Denali Pass, one of the most hazardous sections of the mountain. A fourth climber from the same team survived in critical condition.

Mount McKinley, renamed from Denali in January 2025, stands at 20,310 feet and is North America’s highest peak. Around 1,000 climbers attempt to summit the mountain each year, with a historical summit rate of approximately 51 percent. The risks are severe: more than 130 people have died on its slopes since 1903, according to GearJunkie citing NPS records.

The 14,000-foot camp where Pendery was based sits along the West Buttress route, the path used by most climbers attempting the summit. The camp serves as a staging point for acclimatization and as the main hub for park service medical and safety operations on the mountain.

Tributes came from communities across the Pacific Northwest. Crystal Mountain Resort called her “an avid climber, accomplished alpinist, and dear friend to many” who left “a lasting impact on the mountain community.” The Northwest Avalanche Center described her as “an integral part of our community for years.”

At the time of her death, Pendery was one of two rangers in charge of the 14,000-foot camp, according to a field update published by the park service. She was a climber, a nurse, an avalanche forecaster, a rescuer — among the most qualified people the mountain had ever seen doing that work.

The investigation into how she died on a mountain she had guided others safely up for over a decade continues.
