UPDATE: Missoula Rural Fire Chief Dan Merritt says the grass fire is now contained.
He says a resident on Blue Mountain Road was burning a wood pile when the wind picked up and caused the fire to spread out control over nearly an acre of grass.
The chief says this is a good reminder for people to be mindful of weather conditions during open burning season.
