OSSIPEE, N.H. — A New Hampshire forest ranger says it could take days to put out a brush fire that’s over 130 acres in a steep, rocky area on Bayle Mountain in Ossipee.

The New Hampshire Army National Guard sent out a helicopter to help fight the fire Wednesday, and might return Thursday.

Forest ranger Stephen Kessler tells WMUR-TV the fire is in the middle of the Ossipee mountain range and is fairly remote. He describes it as “hike in, hike out.”

Firefighters from Eliot, Maine, have joined the Bayle Mountain firefighting effort.

Brush fires have been popping up around the state. One in Northfield shut down Route 140 near the Belmont town line, burning about 80 acres. The fire was about a half-mile from homes. Another in Merrimack didn’t threaten any structures.

A fire warning continued Thursday for northern and central New Hampshire.
