I don't think it's camps, cat. The game will re-use z-levels of instanced areas that expire, IE, camps, houses, other dungeons, battles, etc. So what you're seeing is just the remnants of another map; though in camps you shouldn't be able to see outside of the area, or even those yellow squares at the edge, so that's odd.

I think I did add a cache to getting border walls in dungeons, so maybe that's why this is happening.
