Created 512 x 512 Terrain Changed the terrain resolution to 64 x 64 (Very Coarse) Drew a rectangular shape from the top of the terrain to almost the bottom. Removed a few pixels from the side of the rectangular shape to create randomness. Increased the terrain to 1024 x 1024 (Massive Resolution). Filtering section with the default slope, Apply Vertical and then Apply Vertical Add. Added the appropriate Fractal Round Hills size and lightly painted the effect on the overall sloped terrain and especially around the edge of the rectangular. Added some Posterize and some Eroded. Square Edges to the very edge of the terrain and added some Mounds. Increased the Terrain Resolution to 4096 x 4096 (Planetary Resolution). Added Mounds and Height Noise. Super (Fine Art Anti-Aliasing). As you can see, the Mounds on the front of the image look weird as generated solely by the software. The massive rock formation in the background was originally painted and then effects were added.
