NPS Mountaineering Ranger Dies After Crevasse Fall on Denali

Her death, the fourth on the peak this season, has prompted an active National Park Service investigation into conditions on Denali.

Overview

  • Robin Pendery, a seasonal National Park Service mountaineering ranger, fell into a crevasse near 14,000 Foot Camp around 2 p.m. on Thursday, June 4, and did not survive despite immediate rescue efforts.
  • The National Park Service confirmed the death, said rescue teams responded right away, and opened an active investigation but has released few operational details so far.
  • Pendery had served on Denali’s mountaineering staff since 2024 and worked in climber safety, emergency response and medical care; she previously guided for Alpine Ascents International.
  • This is the fourth fatality on Denali in 2026, following a late-May fall near Denali Pass that killed three climbers, raising fresh concerns about early-season hazards on the mountain.
  • Park officials and weather reports note heavy high-elevation snow and changing conditions at play, and investigators’ findings could affect on-mountain patrols, helicopter operations and public safety guidance.
