The easternmost of two pyroclastic cones named Cerros Las Hermanas (The Sisters) appears at the left, with an unnamed cone to the NE on the right horizon. These cones on the low coastal plain along the Gulf of Mexico barely reach 250 m elevation. The cones are located at the NW end of the Aldama volcanic field, an area of Quaternary phonolitic and basaltic pyroclastic cones and lava flows SE of the Sierra de Tamaulipas. Trachytic and phonolitic explosive eruptions were followed by the emission of young basaltic lava flows.
