HAMILTON - Officials with the Bitterroot National Forest in western Montana say a wildfire has burned 75 to 100 acres in steep timber about 12 miles northeast of Hamilton.
Public affairs officer Todd McKay says 20 firefighters, four engines and four helicopters are battling the Dominic Point fire, which was first reported at 3 p.m. Sunday and estimated at 35 acres.
Another 80 firefighters are expected to join the effort early Monday.
The fire briefly threatened Willow Mountain Lookout. A helicopter evacuated Lookout staff, four citizens and a rescue crew after flames crossed the only road in and out of the area.
The cause of the fire is unknown, but McKay says authorities believe lightning may have sparked the blaze during a thunderstorm on Thursday.
