Well, my theory has always been that when the game needs to create a new part of the map (by which I mean a 128x128 "superblock"), they might make one edge match up with whatever is next to it, but they don't bother trying to make the other three edges match. So you end up with these cliffs. Also, in Astronaut_lairs notice the photo at the end, of a narrow corridor that was right up against the edge of a superblock. I have also noticed that the plants that get cut off are also right on the edge of a superblock. In both cases (the lair and the plants) I used my mapping program (see User_blog:Mrob27/Internal_Data_Format) to confirm where the edges of the 128x128 blocks are.
