High on Denali’s frozen slopes, 33-year-old seasonal ranger Robin Pendery was doing what she loved most: protecting climbers and keeping order in one of the harshest environments on Earth. Assigned to the 14,000-foot camp, she spent her days monitoring routes, responding to emergencies, and watching over strangers who trusted the mountain far more than it deserved. On Thursday afternoon, that same landscape turned on her. A hidden crevasse opened beneath her, and within moments, a dedicated protector became Denali’s latest victim.
