The hill on the horizon is El Volcanicillo, a scoria cone that produced two lava flows down opposite sides of a ridge on the NE flank of Cofre de Perote volcano. The forested area extending across the photo below the cone is the Río Naolinco lava flow, a massive 900-year-old pahoehoe flow that reached as far as 50 km from El Volcanillo; the ‘a’a Toxtlacuaya flow traveled down the opposite side of the ridge. Highway 140 is in the foreground.
