The Sierra Nevada east of the Valley of Mexico is a N-S-trending volcanic chain that runs perpendicular to the E-W trend of the Mexican Volcanic Belt. As with other transverse volcanic chains such as Cántaro-Colima and Cofre de Perote-Orizaba, the Sierra Nevada range is younger to the south. The broad forested volcanoes of Tláloc and Telapon in the distance are Pliocene in age, snow-capped Iztaccíhuatl in the center is largely Pleistocene, and steaming Popocatépetl in the foreground has been historically active.
