The unassuming hill on the right-center horizon is El Volcanicillo, a compound cinder cone that fed 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 aa Toxtlacuaya flow traveled down the opposite side of the ridge.  Highway 140 in the foreground, a major transportation corridor between Jalapa and Puebla, cuts across the flow. Photo by Lee Siebert, 2000 (Smithsonian Institution).
