Hi lch:
You found good details. Thanks for the comments.
Yes, the cave entrances are special. I think all of the boundaries are as I intended in terms of the neighbor connections, but the map could make them a bit clearer.
Unfortunately, my GIMP is not working, but I found a replacement for now. Maybe I will be able to tweak the map and fix those things. That might be next weekend's project.
