Cavern-Tunnel Multiple Passages Set A

Publisher's blurb: The Cavern-Tunnel Multiple Passages group of Naked Geomorphs contains 18 tiles, each with one cavern opening (CD, CSD) and three or more connected tunnels (T). Sets A and B are completely interchangeable. I.e., tile M106A can be replaced with tile M106B, without changing the basic structure of your map. Set A has lots of narrow, one-hex wide, passages branching off the larger cavern area.
