The Maya Region is traditionally divided into three cultural and geographic, first order subdivisions, namely, the Maya Lowlands, Maya Highlands, and the Maya Pacific. The Region's internal borders, like some of its external ones, are not usually precisely fixed, as they are rather demarcated by 'subtle environmental changes or transitions from one zone to another.' Additionally, the Lowlands, Highlands, and Pacific are often further subdivided along similarly imprecise lines, giving rise to a myriad roughly-demarcated second order subdivisions for the Maya Region.
