A fire in Prospect that began at midmorning Friday in an unpopulated area near Half Moon Pond burned at least 10 acres before being contained in the evening.

The Maine Forest Service has classified much of Maine as in a high category of fire risk due to drought, including Waldo County, where Prospect is located.

Crews from eight nearby towns joined volunteer firefighters from Prospect to fight the fire, along with the Maine Forest Service, which assisted via helicopter, according to Diane Terry, whose husband, Tim, is the chief of the volunteer fire department.

The Maine Forest Service assisted via helicopter, she said.

At 8 p.m. Friday, firefighters from Stockton and Searsport were still on scene with the crew from Prospect, she added. The Village Soup reported that firefighters from Frankfort, West Frankfort, Stockton Springs, Searsport, Searsmont, Liberty, Monroe and Waldo responded.

Terry said no structures were threatened. She said the fire had begun in a hollow near Half Moon Pond but she wasn’t sure how many acres total had burned. “I have had no conversation with the chief,” she said.

But it was at least 10 acres, she said.

“You could smell it quite a distance,” Terry said.

She had heard from her son-in-law, the chief of Stockton’s volunteer fire department that her husband, who is 73, had walked the entire perimeter of the fire. “He’s sturdy,” she said.

Her son David is also a Prospect volunteer firefighter.
