The Rincón de Chapultepec scoria cone is seen here with a switchback road on the southern flank and is one of the younger vents within the Naolinco volcanic field. The crater rim is barely visible against the tip of a ridge of the Sierra de Chiconquiaco range on which the cone was constructed. The valley floor is underlain by tephra deposits from Rincón de Chapultepec that overlie a lava flow that issued from the base of the cone. Rincón de Chapultepec formed about 3,000 years ago.
