The elongated Iztaccíhuatl has a more conical profile when viewed from the south at the Querentano hut on Popocatépetl. Paso de Cortés, a 3680-m-high saddle, separates the two 5000-m-high peaks. One of the youngest vents of Iztaccíhuatl is a dacitic lava flow north of this saddle. The flow traveled 5 km to the east.
