A tractor with a snow blower was reportedly backing to the south blowing snow to clear a farm drive causing temporary white out conditions on to the highway.
Meanwhile, a southbound Toyota Camry driven by James Harris of Fort Dodge was steering his car to give the tractor more room, crossing the center line and then collided with a northbound Ford Focus driven by Robert Eilerts of Algona.
A passenger in the Harris car, 81-year-old Norma Harris of Fort Dodge died of her injuries in the accident.
Both James Harris and Robert Eilerts were transported to a Fort Dodge hospital for treatment of their injuries.
The accident remains under investigation.
