An avalanche that buried up to 10 backcountry skiers north of Lake Tahoe is the latest tragedy in a deadly winter that has claimed multiple lives across California's mountain ranges. From deadly incidents on Mount Baldy and Mount Whitney to fatal accidents on the slopes of Mammoth Mountain, the state's vast mountain regions have seen a shocking number of fatalities this season, reinvigorating warnings about the dangers of outdoor activities in extreme winter conditions.

Why it matters

The string of deadly incidents in California's mountain areas has raised concerns about public safety and the need for better education and preparation for those venturing into these treacherous environments, especially as extreme weather events become more common due to climate change. The tragedies also highlight the risks faced by rescue teams and the strain on local resources during these emergencies.

The details

The latest incident occurred on Tuesday when an avalanche buried up to 10 backcountry skiers north of Lake Tahoe. Rescue efforts remained ongoing as authorities searched for survivors. This came just weeks after another avalanche killed a snowmobiler in the same region. Other recent mountain tragedies include three hikers dying on Mount Baldy in late December, a hiker found dead in Riverside County's mountain area in January, and several fatal skiing and snowboarding accidents at Mammoth Mountain, including the deaths of a longtime daily skier and a ski patroller.

  • On December 29, three hikers perished on Mount Baldy, while another two were rescued.
  • On January 17, a hiker who was searching for four missing friends was found dead at the bottom of a 150-foot rock face in Anza.
  • A few days later, on January 20, another hiker died within a few hundred feet of the summit of Mount Whitney.
  • On Christmas Day, Raymond John Albert Jr., a 71-year-old known for skiing nearly every day, died on Mammoth Mountain.
  • On December 26, ski patroller Cole Murphy, 30, died a few days after being swept up and injured in an avalanche on Lincoln Mountain.
