[Aztlan] Maya trade routes

[Dan Parker]

A good book on trading routes in that area is:

The Maya Chontal Indians Of Acalan- Tixchel (Hardcover) by Scholes &  
Roys,
     * Publisher: University of Oklahoma Press (1968)

I returned the copy to the library, so I don't have it in front of me  
now, but I remember there was quite a bit of information about the  
Grijalva River network in the book.

Regards,
Dan
