An excellent seed I stumbled across in a world I generated. This seed has the most awesome survival island for singleplayer, multiplayer, and PvP I have seen so far.

It isn't too big but has a foresty area with birch and oak, a small lake, and two caves. There is an underground ravine nearby for mining. Comment to tell me what you have found/done with it!

Edit to add: The underground ravine is directly below the lake.
