GORHAM, N.H. — Cool, wet weather has given firefighters an opening against the Wild River Fire in the White Mountain National Forest near Gorham, New Hampshire, which the Forest Service put at 821 acres on Sunday, according to The Boston Globe and the Portland Press Herald.

Reports differ on how much of the fire is contained. The Press Herald, citing a Sunday update from the national forest, reported 29%, and NHPR, citing the forest's Facebook page, gave the same number. The Globe reported that a Forest Service social media post put containment at about 20%.

Heavier rain than forecast soaked the burn area during the weekend, the Globe reported, and much of the fire had calmed to a slow burn in dead leaves on the forest floor.

Crews are using the break to build up the fire's perimeter and make the paths they travel safer, Forest Service spokesperson Jessie Dubuque said, according to the Globe. The agency expects the blaze to stay inside 856 acres, and it anticipates the containment figure will keep rising, she said.

Getting to the fire is among the hardest parts of the job, Dubuque said. With no road since 2023 storms and no bridge over the Wild River, firefighters reached the fire by utility vehicle and then on foot through the water. They have since dropped a tree across the river to walk over.

The Globe reported that 95 people are assigned to the fire, backed by a pair of helicopters, a bulldozer, two engines, a drone and eight suppression modules.

Officials will not call the fire controlled, meaning put out, until a season-ending soaking of several inches of rain or snow, the Globe reported. Contained means it has stopped spreading beyond a set boundary.

The fire is entirely inside the national forest and endangers neither people nor private land, the Forest Service said, according to the Globe. The area around it remains closed to the public.

The cause is under investigation, the Globe reported. NHPR reported that the Forest Service suspects people started it.

The Signal reported Nov. 2 that the fire, first spotted Nov. 1, had spread across roughly 300 acres and that 40 federal personnel had been sent to fight it.

On Thursday, The Signal reported, citing NHPR, that new mapping put the fire at 856 acres and about 11% contained, making it the largest in the history of the White Mountain National Forest.
