At approximately 1:00 p.m. Tuesday, a rockslide triggered an inbounds avalanche at Mammoth Mountain, California, beneath Starr Chute on the northeast portion of the resort’s terrain, according to a statement shared by Mammoth Mountain on Wednesday, March 26, 2025.

Mammoth Mountain patrollers visited the scene of the slide immediately and conducted a search using transceivers, Recco, avalanche rescue dogs, and probes, the resort said, adding that this search confirmed eyewitness reports that no skiers or snowboarders were in the area at the time of the avalanche.

Search efforts concluded at 3:47 p.m., the resort said.

The avalanche was caught on footage by Mammoth Mountain’s Main Lodge web camera. Tap or click below to watch footage of the slide.

The avalanche follows another slide that occurred at Mammoth Mountain on February 14 that led to the death of ski patroller Claire Murphy. The Valentine’s Day avalanche occurred during avalanche mitigation work after roughly six feet of snow had fallen at Mammoth Mountain in 36 hours. Another ski patroller involved in the incident was unharmed.

According to a fact sheet published by the National Ski Areas Association (NSAA), ski areas have implemented “continuous and aggressive training and education efforts” in pursuit of reducing the occurrence of inbounds avalanche fatalities.

As of October 2024, only seven of the 224 recorded avalanche fatalities over the past ten ski seasons were categorized as occurring “inbounds,” according to the NSAA. Most avalanche fatalities occur outside the controlled boundaries of ski resorts.

Still, the NSAA wrote, “avalanches remain an inherent risk of skiing.”
