A fire continues to burn in a cavity within the Doerner Fir, one of the world's tallest trees, in Oregon's Coast Range. Firefighters have contained the spread but are struggling to extinguish the stubborn blaze 280 feet up the tree. Helicopters and hand crews have been deployed, but a hot spot remains. Arborists are consulting on how to reach the fire, and the cause is under investigation, with human activity a possibility. The area remains closed.
