Global Volcanism Program | Image GVP-11364

The broad forested ridge in the center of this photo is the Tenango lava flow, which was erupted about 8,500 radiocarbon years ago from an E-W-trending fissure at the western margin of the Chichinautzin volcanic field. It forms a prominent isolated mesa on which the fortified city of Teotenango with its many pyramids and courts was built by the Matlatzinca people about 1000 BCE.
