The Laguna Alchichicha maar is the largest of the Serdán-Oriental volcanic field, located just off Highway 140 between Puebla and Jalapa. The low rim of the maar increases in height to the west. The pyroclastic surge deposits contain juvenile fragments of scoriaceous basaltic or basaltic-andesite material. Tufa deposits such as those in the foreground are located along the shore of the lake. Cerro Pizarro in the distance is the northernmost lava dome of the Serdán-Oriental field.
