It's a single height_field made from a function.

I start with a highly exponentally raised noise3d function:

#include "functions.inc"
#declare f_hills = function (x,y,z) {f_noise3d(x,y,z)^10*15}

I clip that function in the 0-1 range and add some smaller noise to it that
increases with altitude:

#declare f_nhills =
function (x,y,z) {
   min(
      1,
      (
         f_hills(x,y,z)
         * (1+f_noise3d(x*10,y*10,z*10)*1.0)
         * (1+f_noise3d(x*30,y*30,z*30)*0.5)
      )
   )
}

I then add together three of these f_nhills functions with different
strengths and also add a f_ridged_mf function to it all. The rest is
tweaking.

Hope that helps!
