Overview The Olmec heartland is the area in the Gulf lowlands where it expanded after early development in Soconusco, Veracruz. This area is characterized by swampy lowlands punctuated by low hills, ridges, and volcanoes. The Sierra de los Tuxtlas rises sharply in the north, along the Gulf of Mexico's Bay of Campeche. Here, the Olmec constructed permanent city-temple complexes at San Lorenzo Tenochtitlán, La Venta, Tres Zapotes, and Laguna de los Cerros. In this region, the first Mesoamerican civilization emerged and reigned from BCE.Dates from Pool, p. 1. Diehl gives a slightly earlier date of 1500 BCE (p. 9), but the same end-date. Any dates for the start of the Olmec civilization or culture are problematic as its rise was a gradual process. Most Olmec dates are based on radiocarbon dating (see e.g. Diehl, p. 10), which is only accurate within a given range (e.g. ±90 years in the case of early El Manatí layers), and much is still to be learned concerning early Gulf lowland settlements.
