A massive search operation is underway near Castle Peak, California, after an avalanche struck on Tuesday, leaving six backcountry skiers rescued and ten others unaccounted for. The incident occurred amidst a powerful winter storm that has blanketed the Lake Tahoe region with heavy snowfall and triggered avalanche warnings.
The Nevada County Sheriff’s Office received a 911 call around 11:30 a.m. Reporting individuals buried in the snow near Castle Peak, a popular destination for backcountry skiing northwest of Lake Tahoe. Search and rescue teams, including personnel from the Sheriff’s Office, the California Department of Forestry and Fire Protection (CAL FIRE), immediately mobilized to the area, according to Sheriff’s Office spokesperson Ashley Quadros.
Authorities initially reported 16 people were involved – four ski guides and 12 clients – but have since revised that number to 15. Blackbird Mountain Guides, the company leading the skiing trip, stated the group was returning from a three-day excursion at Frog Lake when the avalanche occurred. Two of the rescued skiers were hospitalized for treatment, though their conditions have not been released.
Dangerous Conditions Prompted Avalanche Warning
The avalanche occurred as a major winter storm continues to batter California, bringing dangerous conditions including thunderstorms, strong winds and significant snowfall to mountainous areas. The Sierra Avalanche Center, based in Truckee, had issued an Avalanche Warning for the Central Sierra Nevada, including the Lake Tahoe region, citing high avalanche danger in backcountry areas. Large avalanches were expected Tuesday and into Wednesday, according to the center’s forecast.
Castle Peak, rising to 9,103 feet in the Donner Summit area of the Sierra Nevada, is a well-known spot for backcountry skiing. The area had received at least 76 centimeters (approximately 30 inches) of snow in the 24 hours leading up to the avalanche, as reported by the Soda Springs mountain resort. The rapid accumulation of snow, combined with weakened layers in the snowpack and strong winds, created the hazardous conditions. The Sierra Avalanche Center noted that areas with avalanche mitigation programs were not expected to be at such high risk, but backcountry areas remained extremely dangerous.
Several ski resorts around Lake Tahoe were either fully or partially closed due to the extreme weather conditions. The storm has also disrupted travel, with traffic temporarily halted on Interstate 80 near the Nevada border due to spinouts and accidents, as reported by the California Department of Transportation.
Recent Avalanche History and Risks
This incident follows a similar tragedy in January, when an avalanche in the region claimed the life of a snowmobiler, authorities said. Avalanches pose a significant risk in the United States each winter, with the American Avalanche Association reporting that 25 to 30 people die in avalanche incidents annually.
The ongoing search efforts are being supported by specialized rescue ski teams from Boreal Mountain Ski Resort and Tahoe Donner’s Alder Creek Adventure Center. A SnoCat team from Alder Creek is also assisting, along with a leadership team from Blackbird Mountain Guides. The California Office of Emergency Services is coordinating to provide additional resources to aid in the search for the missing skiers.
The Interstate 80 corridor has been significantly impacted by the storm, remaining closed since Tuesday morning from Colfax to the Nevada state line. This closure further complicates rescue efforts and highlights the severity of the weather conditions.
As of Wednesday morning, the search continues for the ten remaining skiers. Authorities are urging anyone planning backcountry activities in the Sierra Nevada to heed avalanche warnings and exercise extreme caution. The Avalanche Warning remains in effect through 5 a.m. Wednesday, with danger rated as “high” below the treeline and above.
The focus now remains on locating the missing skiers and providing support to those affected by this tragic event. Further updates will be provided as the search progresses and more information becomes available.
