It is located on the western Pacific coast, where it rose to become the major regional center following the decline of an earlier polity at Ojo de Agua, Chiapas.

Such an idea is consistent with the quatrefoil shape, which in the Classic period iconography symbolizes a watery portal to the supernatural realm.

Some of the figurines have facial features that anticipate those of the Monte Alto heads and potbellies, including the closed eyes with puffy lids and swollen cheeks.
