The profile of Iztaccíhuatl seen from the summit of Papayo volcano to the north. The northern base of the volcano is the Llano Grande edifice (the oldest edifice of Iztaccíhuatl) and the NW-flank La Trampa lava flows. The low-angle ridge extending to the NE (left) consists of the Teyotl dacite lava flows that erupted from a vent on the upper northern flank about 80,000 years ago. A gas plume can be seen at the summit of Popocatépetl to the far right.
