Firefighters from more than a half-dozen local departments spent seven hours Saturday putting out a fire in Durand.
When crews arrived at about 11:00 a-m they say one of three connected pole barns had burned to the ground and two others were still burning.
They were able to save one of the sheds and limit the damage to a second one.
One firefighter had to be taken to a hospital for non-life-threatening injuries.
The Durand Fire Chief says an investigation is underway to determine a cause for the fire.
