Ski area spokeswoman Brandy Ream told the Tri-City Herald the ski patrol found him injured shortly after noon Saturday at the top of a beginner trail called the Country Road run.
A Life Flight helicopter was requested but unable to respond because of the weather. An ambulance took the boy to Columbia County Hospital in Dayton where he died.
He was an eighth-grader at Columbia Middle School in Burbank.
Ski Bluewood is located in the far southeast corner of Eastern Washington, four miles north of the Oregon border in the Umatilla National Forest.
