Sorry for the crosspost.
I made a video tutorial (as they are all the rage) of this thread as it was recently resurrected. It creeped to almost 12 minutes (I tend to babble).
I recorded the screen in 1024x768 and scaled the video to 640x480 off line.
It is currently hosted at showmedo at 640x480 (though I think will host up to 800x600:

Excellent tutorial! Thanks!
Sorry, but I voted no - not because I couldn't find it of use, but becasue there were no explanations to the steps. It'd be good if you knew what was going on, but to a GIMP noob - sorry I couldn't follow it all,
Take Care,

Rob,
Three things Amigo,
Firstly - it's good to another Cardinal Fang Devotee
Secondly - Excellent tutorial, simple and easy to follow, I will be using this in future
Finally - This process, and all the others I have seem seem to produce a mountain range with the peaks in the middle, which is good enough. But what about escarpment ranges - where for example one tectonic plate, or similar, subducts another, raising the top plate gradually on one side with a steep fall-off on the other where the subdudtion occurs. The prime examples I can think of for this are the Rockies and Andes.
Basically - what I'm asking is how can we reproduce a non central range of peaks within a range? I'm not explaining this too well am I
Take Care
Norm

Normski-
That type of range is even simpler. Just add some noise to a simple linear gradient, then play with the levels and curves.
Here is a simple escarpment heightfield on an oval:
And here is a quick render in POV:
From above (gimp alone):
