  A. Bare soil 
   1.  Lighter tones are generally indicative of one or more of the following: 
    a)  low soil moisture  b)  low organic content 
    c)   finer textured soils  d)  higher topography 

   2. Darker tones are generally indicative of one or more of the following: 
    a)  high soil moisture  b)  high organic content 
    c)   coarse textured soils  d)  area lower topographically 

  B. Soil moisture is most easily distinguished using IR film. 

  In general, the coarser the stream pattern, the more resistant is the bedrock.
