    Sherman

    8 deaths, 45 injured

    What happened

    A wall of dust formed along the cold front that was advancing across the east half of the county. Loose soil from a field near I-70 added to the dust in the air. The visibility fell to zero at MM 28 just east of Edson leading to a multi-vehicle accident in both east and westbound lanes. Seventy-one vehicles, and 80 people, were involved in the accident. All but one of the fatalities/injuries were in the eastbound lanes. All fatalities except for one occurred at the accident scene. One fatality occurred at a local hospital. The dust was so thick that rescuers standing at arm's length could not see one another; there was no frame of reference for up and down at times.
