Aircraft and smoke jumpers were deployed to a 2 acre fire burning in the Rattlesnake Recreational Area Saturday night.
According to Lolo National Forest spokesman Boyd Hartwig, the blaze has been named the Stewart Peak Fire, and is located 2 miles southwest of Stewart Peak.
Hartwig told NBC Montana the fire was likely started by lightning.
No structures are threatened, and no trails have been closed.
We'll have an update on the fire later tonight.
