This is a good tool to have in your arsenal - for Perlin's own presentation:

Also, there's a pretty good paper about the tricks that the "Tribal
Trouble" guys used to make their terrain here:

One thing I've had a hard time finding good references for is a means for
procedurally modeling the effect of glaciers on a heightfield terrain.
River erosion is pretty well covered, and you get "V"-shaped valleys as a
result of rivers. Glaciers behave differently, and their valleys tend to
be more "U" shaped.

I've tinkered with World Machine [http://www.world-machine.com/] and
Terragen [http://www.planetside.co.uk/terragen/] to play around with
terrain, but I'd like to be able to drive the whole process from within my
games, and there are a few pieces that I'm not sure how I'd implement.
Like glaciers.
