I built a new, huge top for our dining room table and my daughter decided we should build a giant map that filled the table. (No argument here.)
None of my pictures captured the entire thing in one pic, but we generally went hot to cold: Desert and lava on one end, giving way to dungeon and rocky land (with an "evil" castle and a graveyard. A river divides it with a swamp/jungle island in the middle, with forest and green mountains, ice world, and rocky mountains with another castle at the other end.
View from the snowy end:
