A National Park Service mountain guide has died after falling into a crevasse on Mount McKinley, officials said.
The incident happened near the 14,000-foot camp inside Denali National Park and Preserve on Thursday. The guide was identified as Robin Pendery, a seasonal mountaineering ranger from Enumclaw, Washington. She was assigned to climbing patrol duties at the time of the fall. Despite rescue efforts, she did not survive.
The National Park Service said she fell into a crevasse near the high-altitude camp area. The agency confirmed she had been working in one of the most remote and dangerous regions of the mountain. Denali is North America’s highest peak and is known for extreme weather and technical climbing routes. At the time of the incident, weather conditions were reported as mild for the region. Temperatures were around 67 degrees, with light winds and cloudy skies.
The ground had heavy snow coverage, including fresh snowfall from the previous weekend. Officials said about two feet of snow had fallen at the 11,200-foot level. Pendery had worked at Denali National Park since 2024 as a mountaineering staff member. Her duties included climber safety, emergency response, and mountain operations. She also worked as a nurse and provided medical support on the mountain. She previously worked with Alpine Ascents International as a professional guide.
Colleagues described her as highly skilled and deeply committed to mountain safety. Gordon Janow of Alpine Ascents said the loss was devastating for the team. He said she was a professional with strong compassion and love for mountains. Denali Superintendent Brooke Merrell said staff members are heartbroken by the loss. She said mountaineering rangers serve visitors in one of the world’s toughest environments. The National Park Service has launched an investigation into the cause of the fall. Authorities have not yet released further details about how the accident occurred. The park service said more information will be shared once the review is complete.
Pendery was known among colleagues for her calm leadership in high-risk situations. She often helped coordinate emergency responses during challenging climbs. Her work combined medical training and advanced mountaineering expertise. Alpine Ascents said she guided expeditions in both Washington and Alaska. She was certified in multiple climbing disciplines and rescue operations. The organization called her loss deeply painful for the entire climbing community. Friends and colleagues shared messages of grief after news of her death. Many said she inspired others with her dedication and kindness. Officials emphasized the dangers of working at extreme altitude on Denali. Even experienced climbers face serious risks in the mountain’s changing conditions. The park service continues to review safety procedures for high-altitude operations. Support teams remain on alert as the investigation continues.
The Denali climbing season attracts guides and climbers from around the world each year. Rangers play a key role in guiding safety and rescue operations on the mountain. The National Park Service said Pendery had strong experience in both guiding and medical care. Her background made her an important part of the mountain support team. Search and rescue teams responded quickly after the fall was reported. Despite fast action, medical efforts could not save her life. Officials are urging caution for all teams working in high-altitude snow and ice zones.
The area near the 14,000-foot camp remains one of the most technical parts of Denali. Investigators will review weather data, terrain, and team movements during the incident. The park service said it will continue to support Pendery’s family and colleagues. Her legacy is remembered by many in the climbing and guiding community. She is survived by family and friends who are mourning her sudden passing. The National Park Service said safety training will be reviewed after the incident. The investigation remains ongoing with no final cause determined yet. Denali continues to be a challenging environment for all climbing staff.
