Canyons and Cliffs and Biomes Mod overhauls the world generator to build massive mountains, giant caves, and wider rivers. It pushes the world limits from -256 at the bottom all the way up to 1664 in the sky. The mod makes biomes much larger so you can walk through open forests and plains without sudden cuts. Canyons and caves appear less often across the land, but they are much bigger when you find them.
