    Coalinga, California, December 1, 1991 -- Crews cleared burned hulks
      of cars and trucks off an interstate and tried to identify victims of a
      pileup that killed 17 people and injured 150 others during a blinding dust
      storm.

    "Tangled Wreckage...Dust Takes Toll"
       "Eight persons were injured during the early-morning rush hour
      today when 20 vehicles rammed together in blinding dust blowing across
      Interstate 40 just east of the Amarillo city limits." -Amarillo

    Any soil that is loose, dry, bare, and smooth
      is a candidate to be blown by the wind. If that soil is also unprotected
      for some distance, it will erode under windy conditions. | 
  
  
      | 
    Most soil movement is within a foot of the
      ground. 
      
     | 
  
  
      | 
    Soil moved as saltation and surface creep is
      deposited in a road ditch in Iowa.
