Columba volcano, the youngest known vent of the dominantly Pliocene Calatrava Volcanic Field, rises above the Jabalón reservoir (foreground). The massive volcanic field covers an area of over 5,000 km² and contains more than 300 cones, maars, and lava domes. This field is mostly of Pliocene or late-Pleistocene age, although late-stage phreatomagmatic activity at Columba volcano was dated at the mid-Holocene. Fumarolic activity was recorded in the Sierra de Valenzuela area during the 16th-18th centuries.
