To Ken and Jim, Thanks a lot indeed.

I agree about the rockface in the foreground. It is frustratingly not coming 
out as I want it to be. The reason is of course that the height_field is too 
smooth at that distance/angle, which cannot be entirely compensated by a 
texture. What I need to do is follow Robert McGregor's tip about adding 
irregularities to the mountain in the foreground. I can also scale them down 
with distance and making them merge with the rocks.

The snow/ice is all to be credited to a nice snow texture by Gail Shaw, she 
presented here a couple of years ago:

//snow texture by Gail Shaw:
#declare T_Snow_close=
texture {
  pigment {rgb <0.95,0.95,1>}
  finish {
    ambient 0.0
    diffuse 1.0
    reflection {0,0.2}
    specular 0.6 roughness 0.008
  }
  normal {granite 0.1 scale 0.01}
}

For the snow in the distance, I simply commented out the normal.

Thomas
