Stony Cliffs Are Cool Wiki

Minecraft builds its hills out of dirt with a thin layer of grass on top. That works on gentle ground, but wherever the land drops away sharply you are left looking at a wall of bare dirt - something a real hillside almost never shows, because loose soil cannot cling to a steep face and the rock underneath ends up exposed.

Stony Cliffs Are Cool adds that missing step. As terrain generates, dirt sitting on a steep exposed face is replaced with stone, so ridges, terraces and cut-away slopes come out with proper rock faces.

The replacement is not applied to dirt in general - it is targeted, which is why ordinary ground is unaffected.

A block is only changed when it is dirt that is genuinely part of an exposed steep face, with stone or similar material already present around or above it. In practice that means the vertical cuts on a hillside qualify, while a gentle grassy rise does not. The block on the surface stays grass, so slopes still look alive from above; it is the cliff face that changes.

Terrain height and terrain shape are completely unchanged. Hills sit where they sat, at the height they were, with the same silhouette - only the material showing on the cut face is different.

It also adds nothing: no blocks, no items, no mobs, no structures, no recipes and no biomes. Nothing about how you play changes, and removing it leaves behind a world whose landscape is still perfectly ordinary.

The rule runs across every overworld biome rather than being tied to a particular climate, so the effect follows the terrain instead of the weather. You will see it most on ridgelines, plateau edges, the sides of river valleys and around the rims of lakes - anywhere the ground has been cut steeply.

Flat biomes simply have less steep ground, so they show less of it. That is intentional: the effect appears where a cliff would actually form.

Because the work happens while land is generated, it applies to terrain created after it is installed. Chunks you have already explored keep the shape and the surface they were born with, so adding this to an existing world will not rewrite the hills around your base.

Walk far enough into unexplored land and the new terrain will generate with stone faces. This also means a world can safely be played with or without it later on - nothing depends on it being present.

The effect is intentionally understated. It is a texture-of-the-world change rather than a landmark generator, so a single screenshot shows less of it than actually walking a ridge does - the difference reads most clearly when you compare the same hillside with and without it.

There is no configuration to set and nothing to maintain; it either shapes the land as it generates or it does not.
