The Cuicuilco pyramid in the southern part of Mexico City was surrounded by lava flows from Xitle volcano about 1,600 years ago. The basaltic flows underlie the area to the right and are exposed in the trench walls around the pyramid. The Preclassic Cuicuilco site is one of the oldest archaeological areas in central México. The earliest occupations date back to 2,100-1,800 BCE, and the pyramid was constructed about 80-600 BCE, when Cuicuilco had become an important Pre-Hispanic city.
