On rock tiles you can [[Prospecting|prospect]] for ore, create [[mining|cave entrances]], and terraform it.
Rock tile terraforming with a pickaxe works in the same way as [[digging]] dirt. Stand on the corner you want to ''lower'', activate a pickaxe, right-click a rock tile, and select ''Mining''. Every few actions you ''lower'' the corner by 1 dirt. All four tiles surrounding the corner must be dug to rock.
You can not raise a rock tile, but you can raise the corner by dropping [[Pile of dirt|dirt]] or [[heap of sand|sand]] on it.
You can also dig Rock up by digging into the dirt. It is widely known that you need to dig 200 or more slopes to find rock.
