Mountain code:
#declare MountFunc = function {"ridgedMF" <0.3, 4, 6, 0.45, 1.9>}
#declare maxH = 5;
#declare MBase =
isosurface{
  function {y - MountFunc(x,0,z)*1*max(0,sqrt(z))}
  eval
  contained_by{box{<-5,-0.1,0>,<5,maxH,maxH*maxH>}}
  texture{MBaseTex}
}
object{MBase scale<150,150,150> translate z*160}

Thanks, mountains are my passion.

Texture for snow it quite good and realistic, but I think that its
diffuse level is probably a little bit too high, usually snow is more
uniformly coloured. And mountains could be more visible, I guess.
Foreground snow field could have different relief as well, now it is too
uniform. 
Here is picture from real mountains (Les Deux Alpes, taken with digital
video camera) to compare with:

Thanks for the photo - a useful reference. I'll try taking the diffuse
down - the current settings were a quick approx. and, given that, closer
than I expected.

Looking at your pic, I've got some ideas for a few changes in the rmf
function.

The forground is just a rough (a noise3d iso).

BTW - this is (possibly) the start of my next irtc entry - scene setting for
the fortress of solitude.

Thanks again.

The sample function i posted in p.g. came from that picture BTW.
