A fire is burning in the Doerner Fir, one of the world's tallest trees in Oregon. The over 325-foot-tall coastal Douglas fir, estimated to be over 450 years old, has been burning since Saturday. While infrared scans show no active flames at the top, heat remains within a trunk cavity. Firefighters are strategizing access for water, considering scaffolding or adjacent trees. Helicopter water drops and sprinklers at the base have reduced activity, and the tree isn't at immediate risk of total destruction, though the fire has already damaged its top. The cause remains under investigation, with lightning ruled out.
