The wrinkled surface of a pahoehoe lava flow of Los Flores volcanic field is exposed near the town of Nuevo Morelos. The basaltic lava flow, seen here about 35 km from its source at Cerro Partido, traveled about 80 km to the SSE down a narrow valley in the Sierra Madre Oriental. The geologic hammer at the lower right provides scale.
