The barren, sparsely vegetated area in the foreground is part of the voluminous Río Naolinco lava flow, which extends about 50 km from the El Volcancillo vent complex on the NE flank of Cofre de Perote. The tube-fed pahoehoe lava flow traveled from 2700 m on the NE flank of Cofre de Perote down to 360 m elevation near the town of Chicuasén at the edge of the Atlantic coastal plain. The 900-year-old lava flow is the youngest of a series of youthful flows erupted on the NE flank of the volcano.
