The lightning-caused Schoolhouse fire burning north and west of Lolo has grown to 250 acres. The fire is the largest of several new fires started by a lightning storm that moved through Saturday night. Smoke from this fire is visible in Missoula and it is one of two fires now burning in the Highway 12 corridor between the community of Lolo and Lolo Pass. The West Fork Two fire south of the highway is 60 acres. Information officer Cindy Super says none of the fires are currently threatening any structures.
