Global Volcanism Program | Image GVP-07490

The small Xitle scoria cone in the center of the photo is directly below Volcán Ajusco, the large lava-dome complex on the horizon, and was the source of a voluminous lava flow about 1,670 years ago. The 3.2 km3 flow traveled 13 km north and underlies much of the forested area in the middle of the photo as well as the southern part of Mexico City in the foreground. The flow covered the Preclassic city of Cuicuilco, one of the oldest archaeological sites in central México, and underlies the campus of the National University of México (UNAM).
