Avalanche Near Lake Tahoe Leaves Ten Backcountry Skiers Missing as Rescue Efforts Complicate

Ten backcountry skiers are unaccounted for after an avalanche struck near Lake Tahoe on Tuesday, as heavy snowfall continued to fall in the area. The group, which included four guides and 12 clients, was in the Sierra Nevada's Castle Peak region near Truckee, California, when the avalanche occurred around 11:30 a.m., according to the Nevada County Sheriff's Office. The event took place at an elevation of approximately 8,200 feet and was rated D2.5 by the Sierra Avalanche Center, indicating a 'large' to 'very large' slide capable of burying or seriously injuring a person. The avalanche's scale and the remote location of the incident have complicated rescue efforts.

At least six skiers survived the event and were awaiting rescue on Tuesday afternoon, with authorities instructing them to shelter in place. The remaining 10 individuals are still missing, prompting a massive search operation. Nearly 50 first responders are currently scouring the Sierra Nevada area near Truckee to locate the survivors and find the missing skiers. A SnoCat team was deployed as part of the search and rescue mission, reflecting the extreme difficulty of the terrain and conditions.

The group had arrived at the Sierra Nevada region on Sunday and was scheduled to check out from the Frog Lake Huts, a backcountry lodge managed by the Truckee Donner Land Trust. Steve Reynaud, an avalanche forecaster with the Sierra Avalanche Center, noted that the usual routes to and from the lodge carry 'some degree of avalanche hazard.' He explained that the group appeared to be heading toward the Castle Peak trailhead, located near the Boreal ski area and adjacent to Interstate-80—a path that passes through 'numerous avalanche hazards.' Reynaud emphasized that an avalanche burying seven to 10 people would typically require either a very large slide or a group being in an especially dangerous location, or both.

The remote location and treacherous weather conditions have severely hindered search efforts. Travel in, near, or below avalanche terrain in the backcountry has been strongly discouraged by authorities, who warn that the situation remains 'highly dangerous.' The Nevada County Sheriff's Office issued an avalanche warning that remains in effect through Wednesday, as rapidly accumulating snowfall continues to add pressure to already fragile snowpack layers amid gale-force winds. These conditions have made rescue operations particularly challenging, with Reynaud stating that 'there's not an easy way for search and rescue or outside help to get there.'

Even getting rescue personnel to the location initially has been a major challenge, according to Reynaud. He noted that the current weather conditions are not only dangerous but also make movement in the backcountry extremely difficult due to new snow and wind. A helicopter rescue has been ruled out, further complicating the search. Interstate-80 was closed in both directions through the Sierra on Tuesday morning before reopening at 2:30 p.m. with tire-chain controls in place for vehicles.

The storm has also impacted the Lake Tahoe region, with parts of the area expected to receive four to eight feet of snow by the time the storm ends on Thursday. This extreme weather has led several ski resorts around Lake Tahoe to fully or partially close. While resorts have avalanche mitigation programs and are not expected to face the same level of risk as the backcountry, the Sierra Avalanche Center has warned that travel in avalanche-prone areas remains strongly discouraged.

Brandon Schwartz, the Tahoe National Forest lead avalanche forecaster, highlighted the dangers of the current situation, stating that the backcountry is particularly hazardous due to the height of the storm. The National Weather Service has issued a winter storm warning for the entire Sierra Nevada range, which remains in effect until 10 p.m. on Thursday. The service warned that elevations above 3,500 feet could see significant snow accumulation, further exacerbating the risks for those in the area.

The Nevada County Sheriff's Office is leading the response, working with multiple agencies, including Nevada County Search and Rescue, the Placer County Sheriff's Office, Tahoe Nordic Search and Rescue, the Washoe County Sheriff's Office, Washoe County Search and Rescue, and Truckee Fire. As the search continues, questions about the balance between personal risk and the need for restrictions in avalanche-prone areas remain unanswered. The incident underscores the dangers of backcountry travel during severe weather and the critical importance of preparedness, as even experienced groups face life-threatening conditions when nature intervenes on a large scale.
