On Friday, an in-bounds avalanche buried two ski patrollers on California’s Mammoth Mountain. The resort confirmed on Sunday, Dec. 28, that one of the patrollers, Cole Murphy, died from his injuries.
The patrollers were working on the resort’s Lincoln Peak when the slide occurred around 7:30 a.m. Both were immediately taken to Mammoth Hospital, where they were treated for their injuries.
“With profound sorrow, Mammoth Mountain confirms that the Ski Patroller who was critically injured and hospitalized Friday has died from his injuries,” Mammoth wrote in a Facebook post about the accident. “Cole Murphy, 30, was an experienced patroller with a deep passion for the mountains and love for his career.”
The avalanche occurred after Mammoth received a reported 5 feet of snow in just 3 days. The resort remained closed from Friday, Dec. 26, through Saturday, Dec. 27. It reopened to the public on Sunday.
Severe Avalanche Conditions & Patroller Fatalities
The winter storm that created the conditions for Friday’s avalanche started on Dec. 23 and deposited 4 to 5 feet of snow throughout the Sierra Nevada Mountains. Other parts of the state experienced severe rainstorms and flooding, which resulted in the death of four people.
Avalanche conditions were high across the Sierras following the storm. Murphy and the other Mammoth patroller were working on mitigating in-bounds avalanche danger on Lincoln Peak, a sub-peak within Mammoth Mountain, when the slide occurred. Both patrollers suffered severe injuries, and Murphy was left in critical condition.
Ski patroller deaths at resorts are exceptionally rare. However, this is the second death at Mammoth in 2025. Last February, patroller Claire Murphy (no relation to Cole Murphy) died in the same area of Mammoth on Lincoln Peak.
Mammoth included a statement from Murphy’s family in its post announcing his death.
“The mountain was where Cole felt most alive,” his family wrote. “It was his place of purpose, his community, and his second home. Serving on ski patrol wasn’t just a role for him — it was a calling. To his ski patrol family, the ones who worked beside him, had confidence in him, and shared a bond shaped by snow, service, and unwavering camaraderie: thank you for loving him as one of your own.”
