Minecraft wiki entry for After_Beta_1.8, associated text: Like low/high and selector noise which respectively control the Far/Fartherer and Farther/Farthest Lands, depth noise can be made to overflow at a given position. By default, it overflows at 42,949,672.96 blocks. Due to the Far Lands initiating before it, the overflow in depth noise is effectively impossible to see. However, if depth noise is made to overflow before tradition far lands, achievable by pushing the far lands farther out than this distance or moving the depth noise far lands closer, the effects can be seen: immediately as it overflows, the terrain will jump up a few blocks. Terrain after this point is slightly more boring than before due to depth noise controlling subtle variation, which no longer exists after the overflow due to it almost always being at the max possible value. Every so often, very long "rifts" characteristic of depth noise far lands can be seen, which extend for extremely long. These rifts end once they hit the point twice the distance of the first overflow, and rifts as a whole past this point do not seem to be able to come into existence. Rifts have also only been noted on the positive X axis, and are yet to be found on the Z axis.
