Crews are continuing to battle the Hog Trough and Fuse Lake fires in the Bitterroot National Forest. The blazes — which were both sparked by lightning — have burned a combined 1,287 acres. The Hog Trough Fire is 71% contained while the Fuse Lake Fire is 0% contained. The fires are burning in rugged and remote terrain 18 miles southeast of Hamilton. No structures are currently threatened. Fire managers report the Hog Trough Fire remained active on Tuesday, producing smoke visible from the Bitterroot Valley. The southeast portion of the fire was most active, primarily burning dead and down fuels within the current perimeter and a previously burned area. The fire is slowly backing down the Weasel Creek drainage. Helicopters dropped water throughout the day to cool the fire and enable crews on the ground to have better access to directly attack the fire.
