A field, near county road K-42 and Interstate 29, started burning as part of a controlled burn before 10 o'clock Monday morning, but the wind changed direction around 11.
From there, the fire spread to nearby fields, and even approached the interstate itself.
Fire department's from Sloan, and Whiting, quickly got the fire under control.
But, officials say it could have been a lot worse.
"They got out there and chased it to the interstate fence, and then they got out on 29, because they have all the bells and whistles and stopped it where they stopped it between here and that overhead," John Strain of the Iowa DNR said.
DNR officials say the area that was burned Monday could have been burned at a later time.
