UPDATE - Aug. 23, 2020 - 5:30 p.m.
The Lolo National Forest has released an update on the 30-acre Cinnabar Fire that's burning east of Stevensville.
Firefighters are fighting the blaze which is burning in the Carron Creek drainage in the Welcome Creek Wilderness about 10 air miles east of Stevensville and 15 miles south of I-90 up the Rock Creek drainage on the Missoula Ranger District.
The Cinnabar Fire -- which was sparked by lightning last week -- is producing smoke that's visible from the Stevensville and Rock Creek areas.
The blaze is burning in steep terrain in "heavy downfall and beetle-killed timber" which presents many challenges to firefighters, according to a news release.
The fire was being fought on Sunday from the air with frequent water bucket drops as firefighters continue to assess the opportunity for access on the ground.
There are no structures threatened at this time. There are 14 people assigned to fight the fire.
