Map of Expansion areas? (And any late game tips)

I have 500k income and 95 cities with level 52 max, and most cities over 40. Gold is again the bottleneck (well and clay of course).

Is there a map of the expansion areas? Then I can find cities and clay easily.

And, any later game tips? Seems worth having as many taverns as you can reasonably fit as they generate 300+ gold each if well served via breweries.
