Ravines are natural structures in Minecraft. They replace the ground with air, like caves. Ravines are about 20 blocks tall, 4 to 10 blocks wide, and about 60 blocks long. Ravines can be seen from the surface. If a ravine has its bottom below layer 10, the bottom will be filled with lava. Ravines commonly have water and lava coming from their sides, as well as lots of exposed ores.
