Fast work from firefighters has kept the Blacktail Canyon Fire at about five acres.
The forest fire in dead, standing trees about 4 miles southeast of Butte, was reported Wednesday afternoon near Homestake Pass.
According to Leona Rodreick of the Beaverhead-Deerlodge National Forest, crews have built fireline around two-thirds of the fire and the weather seems to be cooperating today, helping the firefight. No injuries reported.
Two fire engines and a water tender are on the lines, along with the Helena Hotshots.
