I think you just have the height field aligned wrong, try this:
height_field {
   pattern 240, 240 {hf_gray_16 bozo
      color_map {
         [0 color Black]   
         [1 color White]
      }
      scale 0.1
   }
   smooth
   rotate -x*90
   scale <5, 3.8+2, 0.1> translate -<2.5,2,0> 
   texture {
      pigment {color Red}
      finish {specular 0.5}
   }
   rotate x*60
}

Remember that a height field's height varies along the y axis.
Also, the resolution you had(20*20) was too coarse to get good results, 
so I changed it to 240*240, which is more than enough. Probably less 
than 100*100 would be enough with smoothing on.
