this is the pattern that determines the height of the landscape:

  pigment_pattern {
   pigment_pattern {
    crackle scale .75
    poly_wave .125
    warp {turbulence .125 lambda 3}
   }
   pigment_map {
    [0 rgb 0]
    [1 granite scale 10
    scale .5 warp {turbulence .75 lambda 3} scale .5
    ]
   }
  }

cu!
