The fire on Elevation Mountain is estimated to have doubled in size.
The Montana DNRC is estimating the fire has grown to 10-12 acres after reportedly being about six acres on Monday.
The DNRC's Clearwater Unit is currently working on battling the fire, according to a recent update. The fire is located in the Wales Creek drainage in Powell County.
No structures are currently threatened, no evacuations ordered or roads or trails closed.
"Extended attack now includes DNRC firefighters and a state Type 2 hand crew, along with two hotshot crews and eight smokejumpers that are currently working to contain the fire," the DNRC released in a statement. "It is approximately 10-12 acres in size, including a two-acre spot fire, and is burning in thick sub-alpine fir with heavy dead and down timber. The steep, rugged terrain and remote location adds to the incident’s complexity.
"Approximately 70 interagency personnel are assigned to the fire. They include two 20-person hotshot crews, one 20-person state Type 2 hand crew, overhead, and aerial support from three Type II helicopters and one heavy helicopter. Single Engine Air Tankers (SEATs) support with retardant drops as needed."
Firefighters will continue to build containment lines around the fire and crews will mop up any hot spots inside of the perimeter. Current weather conditions could create opportunity for active fires.
