Which city tiles are replaced by salt cities on each map, and where are the rules?

Question

Accepted Answer

One city token of each letter group A-D is replaced by a salt city. Which token is replaced for each letter is printed on the back of the Forum tableau, not in the Salsa rulebook, and the designer says this applies to the base game and later maps too.
