Quaternary lava flows of varying ages cover the entire 4-km-wide field of view in this aerial photo of an area NW of Jalapa. Several lobes of the sparsely vegetated Toxtlacuaya lava flow extend across the center of the photo. The northernmost lobe joins with the darker-colored Río Naolinco lava flow at the upper right. Both of these flows were erupted about 900 years ago from El Volcancillo, a vent on the NE flank of Cofre de Perote. The Toxtlacuaya flow overlies older flows from the Central Cone Complex and still older flows at the bottom from Cerro La Joya.
