Nevada County, California – Eight skiers have been confirmed dead and a ninth remains missing but is presumed deceased after a powerful avalanche struck a backcountry group near Castle Peak north of Boreal Mountain Ski Resort on Tuesday morning.
Authorities said the avalanche occurred around 11:30 a.m. as a heavy snowstorm brought blizzard conditions and high avalanche danger to the Sierra Nevada region. A total of 15 backcountry skiers were caught in the slide, with six survivors rescued from the scene.
Incident Overview
The avalanche took place near Castle Peak in Nevada County, an area known for challenging terrain and backcountry skiing routes. According to the Nevada County Sheriff’s Office, nine individuals were initially reported missing following the slide.
By Wednesday morning, search efforts intensified as weather conditions temporarily improved. Later that morning, sheriff’s officials confirmed that eight of the nine missing skiers had been found dead. The ninth skier remained unaccounted for, but authorities stated that given the conditions at the site, they are presuming the individual has also died.
Officials said none of the eight recovered bodies had yet been removed due to dangerous and unstable conditions. Avalanche poles were placed at recovery points so crews can relocate the victims when it is safe to proceed.
Timeline of Events
The avalanche was reported shortly after 11:30 a.m. Tuesday, as Northern California experienced a strong winter storm system. Blizzard conditions were reported at higher elevations, with limited visibility and significant snow accumulation.
Search operations began immediately but were complicated by ongoing snowfall and elevated avalanche risks. As of Wednesday morning, nine people remained missing. By late Wednesday morning, eight were confirmed dead following extensive recovery efforts.
Authorities stated that search operations for the final missing skier are ongoing but are being conducted cautiously due to treacherous terrain and continuing avalanche danger.
Details From Officials
During a press conference Wednesday, sheriff’s officials outlined the severity of the scene and the dangers faced by rescue crews.
The six survivors included one man and five women, ranging in age from 30 to 55 years old. Two of the survivors were hospitalized for treatment. Officials confirmed that one injured person was stabilized, while the other remained under medical care.
Among the group was a guided team from Blackbird Mountain Guides, which had been leading the skiers on a three-day backcountry trip returning from Frog Lake. The group consisted of four ski guides and 11 clients.
Blackbird founder Zeb Blais issued a statement expressing deep sorrow over the loss.
“This was an enormous tragedy, and the saddest event our team has ever experienced. In addition to mourning the loss of six clients, we also mourn the loss of three highly experienced members of our guide team. We are doing what we can to support the families who lost so much, and the members of our team who lost treasured friends and colleagues.”
Blais noted that each guide was either certified or formally trained in backcountry skiing, and all four guides were qualified instructors with the American Institute for Avalanche Research and Education. The company has suspended field operations through at least February 22.
Avalanche Warning and Risk Conditions
At the time of the incident, an Avalanche Warning had been issued for the region. The Sierra Avalanche Center had rated the danger level as “high.”
Even into Wednesday, search teams faced elevated risks of additional slides. Authorities emphasized that backcountry conditions were particularly unstable due to recent heavy snowfall combined with strong winds, which can create deep and unpredictable snow slabs.
Sheriff’s officials referenced a separate avalanche in January near Castle Peak that killed a snowmobiler, underlining that the area has experienced repeated hazardous conditions this winter season.
Impact on the Community
The Sugar Bowl Academy, a private school and gold-certified U.S. Ski and Snowboard club serving athletes ages 5 to 20, confirmed that multiple academy members were among those who died in the avalanche.
The academy released a statement expressing grief and support for affected families, noting the profound loss felt throughout the skiing community.
Backcountry skiing is a popular activity in the Lake Tahoe region, but officials stressed that even experienced skiers and certified guides are not immune to rapidly changing mountain conditions.
Backcountry Safety Awareness
Authorities used the tragedy to remind outdoor enthusiasts that avalanche warnings should be taken seriously, particularly when danger levels are rated high. Backcountry terrain lacks the avalanche control measures present at managed ski resorts.
Officials advise skiers and snowboarders to:
• Check avalanche forecasts before heading into the backcountry
• Carry proper safety equipment, including avalanche beacons, probes, and shovels
• Travel with trained partners
• Avoid steep slopes during high-risk periods
• Monitor weather changes closely
Even with preparation and training, natural forces can overwhelm experienced groups, particularly during severe storm systems.
Conclusion
The avalanche near Lake Tahoe stands as one of the deadliest backcountry incidents in recent California history. With eight confirmed fatalities and a ninth skier still missing but presumed dead, the tragedy has shaken the regional skiing community.
As recovery efforts continue under dangerous conditions, officials are urging the public to respect avalanche warnings and exercise extreme caution in mountainous areas during winter storms.
