Flames from a van that caught fire on Interstate 82 south of Coffin Road spread to 150 acres before it was contained, according to Benton Fire District 1 spokesman Devin Helland.
The fire started at about 2:30 p.m. Saturday and took about four hours to contain. One person, who was not a firefighter, was taken to a hospital by ambulance for smoke inhalation, Helland said.
The fire burned in brush but came close to crop circles, Helland said.
Visibility was poor at times along Interstate 82 in the area of milepost 122 to milepost 127 because of smoke from the fire.
