I get similar sort of stuff in my Single Player and SMP maps, but then, both of those were started back in the Alpha before the seeds. So it randomly generated terrain as you went out, then if went back later and generated more it could use something totally different and you end up with huge cliffs like that.
I've got an area like that in my Worldmap. It was from when I first generated the map (a really long time ago) and there were some rogue chunks generated, When I finally decided to explore the region I ended up with something similar!
It also happens when the map generates and then you generate more a long time after you've been to that region, though I don't think that happens anymore.
This happens when you generate chunks in a different Minecraft version. If you started this world in 1.3, for instance, but didn't explore to this area until now, the differences in the terrain generating engine cause chunks to be created without regard to the existing chunks.
I only get this when I try to start a multiplayer server, chunk generation in multiplayer is messed up. Generated probably 15 or so maps in single player and did some exploring before I just kept playing one and all of them seem to be fine with no stuff like this. At least you can see a lot of :Coal:...is the bedrock missing? or the sky limit?
I would give the download link, but it wont upload for some reason. :\
This.
There are so many chunk errors there that it looks amazing.
That's pretty wacky. Are you going to use that map for a while? It looks pretty sweet.
There's an Inception joke in there somewhere.
Might just be the game rendered off the pieces without the corner chunk, and that happened.
Or Notch heard u liek chunk errors, so he put a chunk error in your chunk error so you can worship the map gen well you worship the map gen.

Yo dawg we put a chunk error in your chunk error so you can mine while you mine.
Sig'd.
Would be a SHAME if something were to happen to it....
It really would be... :*(
