BANGOR, Maine — Maine Forest Service rangers are battling three wildfires, each of them in remote locations, a district ranger said late Monday afternoon.

One of the fires is near the top of Big Boardman Mountain in Township A, Range 11 WELS, District Ranger Joe Mints said. It has been contained to about 3 acres.

Another is on an island in Upper Lead Mountain Pond, Mints said. He said 3 to 4 acres are affected and that rangers reached it by boat and have it about 25 percent contained.

Rangers also are on their way to a third forest fire, this one in Township 4, Range 9 NWT, also known as Seboeis Plantation, Mints said. Details were not immediately available about that fire, which was reported about 5 p.m.

None of the fires is a threat to buildings, Mints said.
