River width has been exaggerated to depict rapids and other features. The 
Mexican and Guatemalan 1:50,000 topographical maps do not always agree 
on the shoreline. Therefore the accuracy of this map is only ± 100 meters.
Maya site locations are only approximate.
Maya site names are capitalized. If known, the ancient name is shown first, 
with the modern name in parentheses.
Other names are in initial capitals and lower case, with alternate names in 
brackets and informal names in quotes.
