The broad Cofre de Perote massif towers above the eastern margin of the Serdán-Oriental basin. The low-angle andesitic-dacitic shield volcano consists primarily of thick lava flows. Cofre de Perote is the northernmost of a roughly N-S-trending volcanic chain at the eastern margin of the Mexican Volcanic Belt that extends southward to Orizaba volcano. The ridge in the center of the photo is an outcrop of Cretaceous limestone that underlies the Cofre-Orizaba volcanic chain and is exposed on either side of the range.
