For seb and elipsis1 and other noobies having difficulty connecting the banana crumble clip file, I've attached, below, an image illustrating the complete node network incorporating the clip file. The tgd, and a render of the scene. You should notice when you refer to the tgd that I have increased the scale and displacement values of the first power fractal shader, and the strata & outcrop shader to increase the size of the terrain features.
