I like the fact that you changed the port/mine symbols. I always hated that they were basically upside-down versions of each other. The only think I would tweak is to highlight every 5/10 space on the scoring track.
The port/mine fix was sorely needed, although I thought the pick axe worked fine as a mine.
You might get some confusion over what counts as a mountain space with this map. ("No, you only get the mountain attack bonus from a purple space, not a space with a picture of a mountain on it.")
Still, all your map redesigns are very impressive. Thanks for them!
