Firefighters finished mopping up a 10-acre grass fire at about 3 p.m. Thursday near Hardin.
Crews from Big Horn County and the Haley Bench Fire District extinguished the blaze along Interstate 90 near mile marker 472.
It isn’t clear yet what started the fire.
Firefighters also were mopping up on a blaze that began in a hayfield off of South 64th Street West.
Corey McIlvain, deputy Laurel fire chief, said the fire on 64th Street West was caused by a farmer who was baling straw after the barley harvest. A mechanical problem on the farm equipment sparked the straw.
McIlvain said the farmer had a water truck, but the pump was broken. Another farmer from down the road came over with his water truck, but wasn’t able to knock down the flames before fire got out of hand.
Five Laurel firetrucks with 10 firefighters and one Billings brush truck with a crew of two got the blaze under control. No structures were threatened.
“We’ll spend the afternoon mopping up those until they’re out cold,” McIlvain said.
