As far as doing things in TG goes.
How about this?:
I can imagine a few ways to go about getting this break up on a flat terrain floor. But how would you get this into some alpine like mountains, so that it was scattered about in a believable way?
I suppose the first thing to do would be get the effect on a flat terrain ground. Then make a clip. Then try to make smooth angular mountains like in the image. Then try to apply the clip... Yeah, easier said than done! Would love to see it though.
