California Avalanche Kills Eight Skiers
A fatal avalanche in California's Sierra Nevada killed eight backcountry skiers and left one missing this week. The guide company had issued warnings about unstable snowpack prior to the trip. The tragedy highlights changing weather patterns challenging old safety assumptions in outdoor adventure tourism.
- The avalanche on February 17, 2026, near Castle Peak is the deadliest in modern California history, with a death toll that surpasses the seven fatalities in the 1982 Alpine Meadows avalanche. The guided group consisted of 11 clients and four guides from Blackbird Mountain Guides. Three of the company's guides were among the deceased. - On the morning of the avalanche, the Sierra Avalanche Center had issued a "High" danger warning for all elevations. The forecast explicitly stated, "Travel in, near, or below avalanche terrain is not recommended today," and predicted a "widespread natural avalanche cycle." The storm had deposited between 3 and 6.5 feet of new snow in the region in the preceding days. - The Nevada County Sheriff's Office is conducting an investigation into whether criminal negligence was a factor in the deaths. Additionally, Cal/OSHA, the state's workplace safety agency, has opened its own investigation into Blackbird Mountain Guides. - The victims were primarily parents, mostly mothers, connected to the Sugar Bowl Academy, a local competitive ski school. Six skiers, five clients and one guide, survived the avalanche after taking shelter and communicating with rescuers via a satellite device. - The incident occurred amid a surge in popularity for backcountry skiing. Backcountry alpine touring participation saw a significant increase, with 30% of snowsports survey respondents participating in the 2022-23 season compared to 17% the prior season. - Seasonal forecasts for the 2025-2026 winter in the Sierra Nevada indicated the potential for a drier season overall due to La Niña conditions, but with volatile "boom-bust" periods of precipitation. Experts had warned that a weak, early-season snowpack followed by heavy storms could create unusually dangerous avalanche conditions.
