If it wasn't the the MASSIVE loving amount of lighting errors, this whole area would look amazing. I found covers, overhangs, etc. If someone could load all the changes of the area and run some program to force light updates, you could use this place.
Edit: These mountains, too: 880, 100, -230
Edit2: Massive floating island: 440, 103, -383
Edit3: Minecraft 1.6 general:
Jeb just stated horses will be harder to find in the wild now, and their equipment will only be found in dungeon chests. However, dungeons will now have more chests. I hope this doesn't include horse saddles... probably does... "Find dungeons again. :(" ?
