Day trip from La Casa del Rector, hotel in Almagro, to the volcanic Campo de Calatrava area.
The Columba Volcano (38º-45'-30 "N / 3rd-47'-00" W) is located south the Jabalón River, in the vast lowland that extends from the southern flank of the anticline of Almagro, to the Sierra de La Calzada. It originated a slender cone topped by a double subcircular elongated depression which corresponds to the crater. Like other volcanoes in the Campo de Calatrava area, the hydromagmatic eruptions took place in three of the many eruptive stages that affected the region. These eruptions issued high-powered casts along with pyroclastic surges, muddy flows (lahars) and abundant pyroclastic fall. The open quarries on the slopes of the Columba cone have altered its appearance.
