A fire burning in the 325-foot-tall Doerner Fir, one of the world's tallest trees in Oregon, is being fought by authorities. While active flames have subsided, heat remains within a trunk cavity. Challenges include accessing the high cavity to extinguish the fire. Helicopters and sprinklers are being used, and the cause, ruled out as lightning, remains under investigation. Though 50 feet of the top has burned, the tree is not imminently threatened due to its size, and efforts are focused on saving it.
