+The lowest layer of the block array is always lava, having been set so during strata generation. A few lava flooded caves might form. Only width x height x depth / 20,000 lava sources will be seeded.
 
 For each lava source a random x and z coordinate value is chosen and the y coordinate is set to (water level - 3) x randomFloat() x randomFloat(). If the position is AIR then lava is flood-filled from that point.
