If you go to the sign saying 'Put stuff in this box so you don't lose it' and then go down the map in a straight line, until you get to desert. There's a little skinny bit of desert the goes between two blobs of ocean? Just above and to the left of that there appears to be a surface spawner,

There also seems to be quite a few chunk-error style generation artifacts.

Minecraft servers with world maps that allow users to select different view styles need to be gently careful. One longform troll is to mine an enormous swastika at a specific depth. It takes so long to do this that map-resets are unpopular.
