"Nine people died in the Castle Peak avalanche on February 17, 2026, during one of the biggest storms in the last 50yrs. This is a internationally certified guide's breakdown of what happened, why it happened, and what you can do to prevent further deaths. We cover the snowpack, the terrain, the four route options, the human factor traps, and why the backcountry community, guides & the public, need stop-and-go guardrails like other high risk industries where lives are on the line."

"The #snow has stopped but not before giving us another 18.5″ (47 cm) in the last day. That brings our 5-day total to 111″ (281.5 cm), the third snowiest 5-day period on record at the lab behind December 1970 (113″) and April 1982 (118.5″) with digitized records beginning in 1970."

On February 17, 2026, nine people died in an avalanche at Castle Peak during one of the largest storms in 50 years. The UC Berkeley Snow Lab recorded 111 inches of snow over five days at Donner Summit, the third-largest 5-day total since 1970. This represents the deadliest ski and snowboard avalanche in North American history. An internationally certified guide analyzed the incident, examining snowpack conditions, terrain factors, route options, and human decision-making that contributed to the tragedy. The analysis emphasizes the need for structured safety protocols and guardrails in backcountry skiing similar to those in other high-risk industries to prevent future fatalities.
