UPDATE: A tragic avalanche incident just north of Lake Tahoe has claimed the life of 42-year-old Chris Scott Thomason from Bend, OR. The accident occurred on Monday, December 25, 2023, when Thomason and a group of experienced snowmobilers were caught in a large avalanche while returning from Castle Peak.
Despite being equipped with the latest safety gear, including avalanche beacons, the group was unable to save Thomason in time. The group had set out from Johnson Canyon on Donner Pass, fully prepared for winter conditions that have dominated the region following a series of atmospheric river storms. Recent snow accumulations have reached up to six feet in nearby areas, creating treacherous conditions.
According to the Nevada County Sheriff’s Office, Thomason was buried under the snow after the avalanche struck. His companions quickly activated their beacons to locate him, managing to dig him out shortly after the incident. However, the rapidly consolidating snow made rescue efforts increasingly urgent.
Upon freeing Thomason, his friends immediately began cardiopulmonary resuscitation (CPR). An off-duty medic from the Truckee Fire Department arrived shortly thereafter and joined the life-saving efforts. Despite their quick actions and the presence of trained rescuers, Thomason did not survive.
This incident marks the latest in a string of avalanche-related fatalities this holiday season, highlighting the dangers of winter sports in the Sierra Nevada. Just days prior, on December 27, another snowmobiler was buried at Latopie Lake in Mono County and required airlifting for severe injuries. Earlier, on December 26, a tragic avalanche at Mammoth Mountain took the life of Cole Murphy, a thirty-year-old ski patroller.
The Sierra Avalanche Center has issued warnings about ongoing avalanche risks, stating, “Triggering an avalanche remains possible today, especially on slopes where wind-blown snow has filled in terrain features.” Authorities emphasize caution as conditions remain unstable across the region.
As the winter season continues, the community mourns the loss of Thomason while grappling with the dangers posed by recent weather patterns. The avalanche risks are high, and snowmobilers are urged to prioritize safety and readiness when venturing into the backcountry.
For those in the area, stay updated on avalanche conditions and heed warnings from local authorities. The situation remains fluid, and the community’s safety is paramount as more snow is forecasted in the coming days.
