Good Mountain to Cave Transition

[JakeCWolf]

(This might not be the right place to ask, but I'm lost on a better section for this, so if this is in the wrong sub forum, I apologize and please feel free to move it.)

I was looking for a little Wesnoth Map Editor help, namely a good way to make a mountains to cave translation, one that didn't make the mountains look meek and tiny compared the imposing cave walls. Most maps I see that deal with such transitions just seem to use a Keep in the side of mountain and leave it at that.

Any suggestions?
