The large, steep-sided Xicomulco lava flow descends from the flanks of the Sierra Chichinautzin into the Valley of Mexico. The viscous lava flow averages 75 m in thickness, displays prominent flow levees, and traveled 4.5 km north. The flow was extruded with very little explosive activity and the vent was subsequently filled in and is now overlain by the town of San Bartolo Xicomulco (right-center). In the background is the town of San Pablo Oztotepec. Volcán Tlaloc is the broad volcano in the center of the horizon.
