A fire burning in the Doerner Fir, a 325-foot-tall coastal Douglas fir in Oregon, is being fought by authorities. While infrared scans show no active flames at the top, heat remains within a tree cavity. Extinguishing the fire presents challenges due to the tree's height. Helicopter water drops and sprinklers have been used, and the cause, ruled out as lightning, remains under investigation. Though 50 feet of the top has burned, officials are optimistic the tree, a potential global height contender, won't be completely destroyed due to its immense size.
